extjs grid Select All checkbox issue - asp.net

I Want to get the total count of rows fetched when the user selects/checks SelectAll checkbox in Extjs grid.
Pls let me know how to do this.

To get all the rows in a grid, use:
store.getRange();
To only get the selected rows use:
var selectionModel = grid.getSelectionModel();
var selected = selectionModel.getSelection();

You can use like,
var sm = grid.getSelectionModel();
var Selected_record_count = sm.getCount()
Explanation;
getSelectionModel() - Returns the selection model being used and creates it via the configuration if it has not been created already.
getCount() - Returns the count of selected records.

Trying To Filter Only Rows That Meet Two Criteria

I promise I have read through the Query information page, but obviously I am missing/misunderstanding something.
I have a Table that has the statuses for multiple departments (the fields are Strings). When a user loads that table I want App Maker to hide jobs that have been finished.
The way we categorize a job as finishes is when:
The Inventory Status = Complete and when the The Delivery Status = Delivered.
Both these conditions need to be met.
Example:
Inventory (Complete) + Delivery (Delivered) = hide
Inventory (In Progress) + Delivery (Delivered) = don't hide
Inventory (Complete) + Delivery (Scheduled) = don't hide
I tried the following, however it hides all the example listed above, not just the first one.
var datasource = app.datasources.SystemOrders;
var inventory = ['Complete'];
var delivery = ['Delivered'];
datasource.query.filters.InventoryStatus._notIn = inventory;
datasource.query.filters.DeliveryStatus._notIn = delivery;
datasource.load();
I have also tried this:
var datasource = app.datasources.SystemOrders;
datasource.query.filters.InventoryStatus._notIn = 'Complete';
datasource.query.filters.DeliveryStatus._notIn = 'Delivered';
datasource.load();
But I get this error:
Type mismatch: Cannot set type String for property _notIn. Type List is expected. at SystemOrders.ToolBar.Button2.onClick:2:46
Any help would be greatly appreciated.
Filters are using AND operator. Please consider switching the Datasource Query Builder and applying the following query:
"InventoryStatus != :CompleteStatus OR DeliveryStatus != :DeliveredStatus"
Set CompleteStatus variable to Complete
Set DeliveredStatus variable to Delivered
Explanation:
Filter you want to apply is "NOT(InventoryStatus = Complete AND DeliveryStatus = Delivered)" which is equivalent to "InventoryStatus != Complete OR DeliveryStatus != Delivered".
Vasyl answer my question perfectly, but I wanted to add a few details in case anyone needs to do the same thing and aren't familiar with using the Datasource Query Builder.
All I did was click the Database I was using and then clicked the Datasources section at the top.
I clicked Add Datasource, named it a new name and pasted Vasyl's code into the Query Builder Expression box.
Two new boxes appear below it allowing me to enter the desired statuses that I wanted to filter out.
Lastly I went back to my Table and changed its datasource to my newly created datasource.
Since you are changing your datasource, if you have any extra code on there it may need to be updated to point to the new datasource.
Example:
I had some buttons that would filter entries for the various departments.
So this:
widget.datasource.query.clearFilters();
var datasource = app.datasources.SystemOrders;
var statuses = ['Complete'];
datasource.query.filters.WarehouseStatus._notIn = statuses;
datasource.load();
had to change to this:
widget.datasource.query.clearFilters();
var datasource = app.datasources.SystemOrders_HideComplete;
var statuses = ['Complete'];
datasource.query.filters.WarehouseStatus._notIn = statuses;
datasource.load();
You can use multiple run and then concatenate their results something like following
/**
* Retrieves records for ActionItems datasource.
* #param {RecordQuery} query - query object of the datasource;
* #return {Array<ActionItems>} user's rating as an array.
*/
function getActionItemsForUser_(query) {
var userRoles = app.getActiveUserRoles();
query.filters.Owner._contains = Session.getActiveUser().getEmail();
var ownerRecords = query.run();
query.clearFilters();
query.filters.AddedBy._contains = Session.getActiveUser().getEmail();
var addedByRecords = query.run();
return addedByRecords.concat(ownerRecords);
}

How Can I Duplicate A Item/Record?

(Deleted my old question to simplify it. )
I enter data in a table, I then want to make an exact duplicate of that data in a new item/record/row*.
*not sure the proper term.
Is there any way to accomplish this?
Sorry for the slow response. Here is what you should do:
Add a "copy" button in the row. In the onClick on that button, add this code:
var createDataSource = widget.datasource.modes.create;
var rowDataSource = widget.datasource;
createDataSource.item.foo = rowDataSource.item.foo;
createDataSource.item.bar = rowDataSource.item.bar;
// And so on for each field
createDataSource.createItem();
You could probably make sure of javascript for-in to loop through all the properties of the item in so you don't have to manually specify each record, but I didn't have time to experiment with this.
Edit:
The above code won't show the copied record in the list immediately, because I used row's create data source, instead of the lists create data source. Try this instead:
var rowDataSource = widget.datasource;
// Instead of using the row datasource for create, explicitly use the data source of your list.
var listDatasource = app.datasources.NameOfYourListsDataSource;
var createDataSource = listDatasource.modes.create;
createDataSource.item.foo = rowDataSource.item.foo;
createDataSource.item.bar = rowDataSource.item.bar;
// And so on for each field
createDataSource.createItem();

Flex 3: dynamically created checkbox column in datagrid - data population issues and event listener

I have a datagrid control in my mxml file:
Now in my AS file, in the result function when obtaining data from DB, I can create columns dynamically. Let's say I create 1 column (client name):
private function GetDebtors_Result(event:ResultEvent):void
{
var arrayCol:Array = new Array();
var xmlSrc:XML = new XML("<main></main>");
var xmlTmp:XML;
var colClientname:DataGridColumn;
//Build an XML from DB data received (could as well use "event.result" directly to act as dataprovider for the datagrid, but I needed to break it down here)
for each(var o:Object in event.result)
{
xmlTmp = <row>
<CLIENTNAME>{o.CLIENTNAME}</CLIENTNAME>
</row>;
xmlSrc.appendChild(xmlTmp);
}
//Create the column CLIENTNAME
colClientname = new DataGridColumn("CLIENTNAME");
colClientname.headerText = "Client Name";
//Add the newly created column in the "Column" array.
arrayCol.push(colClientname);
//Use the "Column" array to set the columns of the datagrid.
dgSearch.columns = arrayCol;
//Populate the datagrid with the XML data.
dgSearch.dataProvider = xmlSrc.row;
}
This works well.
Now comes the issue: I need to add a second column which will contain checkboxes. They will be selected or deselected depending on the data from database. I'll show how I've done it by updating the same "GetDebtors_Result" function as above (added lines are commented as "// ADDED"):
private function GetDebtors_Result(event:ResultEvent):void
{
var arrayCol:Array = new Array();
var xmlSrc:XML = new XML("<main></main>");
var xmlTmp:XML;
var colClientname:DataGridColumn;
var colSel:DataGridColumn; // **ADDED**
//Build an XML from DB data received (could as well use "event.result" directly to act as dataprovider for the datagrid, but I needed to break it down here)
for each(var o:Object in event.result)
{
xmlTmp = <row>
<CLIENTNAME>{o.CLIENTNAME}</CLIENTNAME>
<SELECTED>{(o.SELECTED == 1)?true:false}</SELECTED> //**ADDED**
</row>;
xmlSrc.appendChild(xmlTmp);
}
//Create the column CLIENTNAME
colClientname = new DataGridColumn("CLIENTNAME");
colClientname.headerText = "Client Name";
//Create the column SELECTED
colSel = new DataGridColumn("SELECTED"); // **ADDED**
colSel.headerText = ""; // **ADDED**
colSel.itemRenderer = new ClassFactory(mx.controls.CheckBox); // **ADDED**
colSel.dataField = "SELECTED"; // **ADDED**
//Add the newly created column in the "Column" array.
arrayCol.push(colClientname);
//Add the "selection" column in the "Column" array.
arrayCol.push(colSel); // **ADDED**
//Use the "Column" array to set the columns of the datagrid.
dgSearch.columns = arrayCol;
//Populate the datagrid with the XML data.
dgSearch.dataProvider = xmlSrc.row;
}
Problem #1: The checkbox column appears, I can check and uncheck the checkboxes, but they are not checked/unchecked respective to DB data when loaded.
Problem #2: How do I associate a function to the checkboxes, for instance one which will update the XML so that I can save the new data to the DB?
Anybody got the solution? Thank you in advance.
Seems to be a very old question that I saw today.
Hopefully you would have found out the solution by now, just in-case if anyone has same problem:
While adding a checkbox to column- just instantiate it 1st:
var chkTempCheck: Checkbox = new CheckBox();
Then set all the properties required:
chkTempCheck.selected = o.dBColumnToDecideCheckUnCheck
here 'o' is the Object you are using from event.result.
This will work for sure!
The initial scenario was: all columns were defined in the mxml file. The checkbox column used itemrenderer and was working properly. I was using the same datagrid in 3 different cases - only thing was that some columns were set visible/invisible depending on the 'views'. The problem was when shifting 'views' and populate the grid and shift 'views' again, the column widths kept increasing exponentially. I excluded the checkbox column and everything worked fine; columns widths were ok. I included the checkbox column back and tried setting the column widths in AS file and the column-increasing-exponentially problem was fixed but the column widths were never the same when populating grid in view A and when populating grid in view B. ...So I ventured out in trying to set the columns in AS file just after obtaining DB data. Hope you can find yourself in those situations. Thanks for helping.

How to update content in Row after selection in dojo datagrid

I have created one dojo datagrid. Every column has a formatter attached to it. When grid is generated the formatter is called. Now I want it so that if a user selects any row the formatter will be called and some strings should be attached to the selected row's column element.
Like grid is like this :
COLUMN
-------
a
b
c
and now user selects the 2nd row, the grid should change to :
COLUMN
-------
a
b SELECTED
c
Currently I implemented it like this :
if(this.grid.selection.selectedIndex !== -1){
retrun value + "SELECTED";
}else{
return value;
}
Can you please suggest a some good way of doing this? Please note that "SELECTED" string should not be added to the grid store.
The formatted is not hooked into clicking / selection of rows. It is solely performed when the contents (value) of a cell is set. Instead you'd want to move focus over to onRowClicked - an event on the grid component. It works like this:
grid.onRowClick = onRowClickHandler;
I wouldnt know which of following samples would put you closest to your goal but onRowClickHandler could be setup as such:
function onRowClickHandler(evt) {
var rows = this.selection.getSelected();
// perform cell rendering here
dojo.forEach(rows, function(row) {
// this row is an item though.. you will have row._O as its index
});
}
OR
function onRowClickHandler(e) {
var cellClicked = this.focus.cell
cellClicked.formatter();
}
However you may find that there are not much references to the viewable data anywhere in the grid component.. You could use following query selectors to find cell data and update the viewed html by calling formatter on each value. You would need to capture a previous selection for 'teardown' of your custom setting of values though.
var prevSelectedRows = [];
function onRowClickHandler(evt) {
var idx = this.selection.selectedIndex,
rawRow = dojo.query(".dojoxGridRow:nth-child("+(idx+1)+")", this.domNode)[0],
self = this;
// perform resetting of viewable values
dojo.forEach(prevSelectedRows, function(raw) {
dojo.query('.dojoxGridCell', raw).forEach(function(cellDOM, i) {
cellDOM.innerHTML = cellDOM.innerHTML.replace("SELECTED", "");
});
});
prevSelectedRows = []; // reset prev selection
// look into grid.view.content for methods on this
// perform setting of viewable values (SELECTED)
dojo.query('.dojoxGridCell', rawRow).forEach(function(cellDOM, i) {
// this function might be of interest, lets see how it looks in console
console.log(self.layout.cells[i].formatter);
cellDOM.innerHTML = cellDOM.innerHTML + "SELECTED"
});
prevSelectedRows.push(rawRow);
}

CheckBox header renderer with HierarchicalCollectionView

I've gotten a checkbox header renderer to work well with flat DPs, but a
hierarchical collection view is another story. On click, I want it to select all
checkboxes in a given column. Here is my code:
var dp:HierarchicalCollectionView = _dataGrid.dataProvider as
HierarchicalCollectionView;
var testDp:GroupingCollection = dp.source as GroupingCollection;
var rawDp:ArrayCollection = testDp.source as ArrayCollection;
for(var i:int=0 ; i < rawDp.length ; i++){
rawDp[i][_dataField] = cb.selected;
}
It selects all checkboxes on the 2nd level of data, but doesn't select the top
level of data. What am I missing here? I can't seem to find it.
Any tips are greatly appreciated. Thank you.
For hierarchical data you have to use a cursor which iterates over all levels of the hierarchical data.
var dp:IHierarchicalCollectionView = _dataGrid.hierarchicalCollectionView;
var cursor:IViewCursor= dp.createCursor();
while (!cursor.afterLast)
{
cursor.current[_dataField] = cb.selected;
cursor.moveNext();
}
Howerver, this works only with nodes that have previously been opened. So either expand all nodes with _dataGrid.expandAll() (you can collapse them afterwards since the nodes only have to be opened once) or iterate your hierarchical data manually:
function setCheckBoxValue(children:ArrayCollection, value:Boolean):void
{
for each (var child:Object in children)
{
if (child.hasOwnProperty("children") && child["children"])
setCheckBoxValue(child["children"], value);
child[_dataField] = value;
}
}
var myDataProvider:HierarchicalData = /* your data provider */;
// Call it like this...
setCheckBoxValue(myDataProvider.source, cb.selected);
Update: To answer your second question...
Create a new CheckBoxColumn which extends AdvancedDataGridColumn. You can use it to preconfigure your headerRenderer and itemRenderer.
In your custom item renderer you get hold of your column like this:grid = AdvancedDataGrid(listData.owner);
column = grid.columns[listData.columnIndex] as CheckBoxColumn;
Do the same in your header renderer.
Whenever the CheckBox value in one of your item renderers changes dispatch a event through your column. Something like: column.dispatchEvent(new Event("checkBoxValueChanged"));
Your header render should add an event listener to the column for the "checkBoxValueChanged" event (or whatever you call it). Whenever that event is fired loop through your data provider and update the headers CheckBox accordingly.
In theory that should work. HTH
