I have created a kendo.data.dataSource without transport (only data with model and fields) with success, and I am able to bind it to the KendoUI Grid on my page.
After loading, the grid is empty. I do calling the net line to add a empty data item in the grid so the user can enter data directly in the grid (inline mode).
$("#divid").data("kendoGrid").addRow();
This all works.
But after the user finished the input and hit the OK/Save button, I like to add a new empty row immediatly, below the previous added row. I try this during the grid function Save:
save: function(e) {
$("#divid").data("kendoGrid").addRow();
}
But the previous row with inserted data disappear and a new empty dataitem isn't added.
Also trying this same way during the datasource event 'change', but with the same behaviour.
My question is, what I doing wrong or what is the best way to add a new empty row to the Kendo Grid when user hits the OK/save button of a current inine editing row.
If you want to save multiple record at a time, you can go for batch editing. You can bind a keypress event to create new row as well. Try this:
$(document.body).keypress(function (e) {
if (e.keyCode == 13) {
var grid = $("#grid").data("kendoGrid");
grid.addRow();
}
});
13 is the value for enter key.

I know how to add a button to a datagridview. What I am having a problem with is changing the text displayed based on whether a associated record exists in another table. I would like to change the text on the button to "View SR" or "Add SR" depending on if a service request exists for the record. if it even possible, how I would go about this ?
You just need to capture the exact cell and cast it in a Grid View Button Cell to adjust the value displayed. Following is a tried solution:
if (SomeTrueValue)
{
((DataGridViewButtonCell)dataGridView1.Rows[0].Cells[0]).Value = "Hello";
}
else
{
((DataGridViewButtonCell)dataGridView1.Rows[0].Cells[0]).Value = "World";
}
I have a created a gridview and added a checkbox in item template. This grid has few columns along with DataKey (primary key). Due to performance gain, this grid will fetch the next set of recrods on each page change based on the page number click. So that is done.
Now when user selects a checkbox in page one and then go to page 2 and coming back to page one, then user will not see the checkbox checked as the user did earlier.
So is there a good way to persist the checkbox when user move page to page?
This checkbox be used as a flag to select the rows that can be deleted later by a button outside the grid.
Since you receive a new set each time a paging is selected, I suggest the following approach:
Create an array[] object via javascript that will add to list the datakey whenever a checkbox is selected and in turn remove it if the checkbox is deselected. Something like this:
var selectedDataKeys = [];
$('.checkboxclass').on('change', function() {
// Considering you assign the data key as id for the checkbox otherwise implement a way to retrieve the id.
var dataKey = $(this).prop('id');
// Determine if the dataKey is in the selected data keys array
var isContained = (selectedDataKeys.indexOf(dataKey) > -1 );
if($(this).is(':checked')) {
// If is contained is false - add to the array
if (!isContained)
selectedDataKeys.push(dataKey);
} else {
// If is contained is true - remove to the array
if (isContained){
selectedDataKeys = $.grep(selectedDataKeys, function(value) {
return value != dataKey;
});
}
}
});
From this point on the client user will have an active list of selected items, now its up to you to use that list to manipulate your grid display page. Either modify the display on document ready by comparing all the item on the grid display with the selectedDataKeys array or sending those keys and do the comparison server side.
Hope this helps.
I have a grid I created in Gridx which lists a bunch of users. Upon clicking a ROW in the grid (any part of that row), a dialog pops up and shows additional information about that user and actions that can be done for that user (disable user, ignore user, etc.) - when one of these options is selected from the pop up, I want to DISABLE that row. The logic for getting the row, etc. I can take care of, but I can't figure out how to make a grid row actually "appear" disabled and how to make that row no longer clickable.
Is there a simple way to do this? If you aren't familiar with gridx, solutions that apply to EnhancedGrids or other Dojo grids are also appreciated.
Alright now that I have a little more information here is a solution:
Keep a list of all the rows you have disabled so far either inside the Grid widget or in its parent code. Then on the onRowClick listener I would write code like this:
on(grid, "onRowClick", function(e) {
if(disabledRows[rowIndex]) {
return;
}
// Do whatever pop up stuff you want and after
// a user selects the value, you can "disable"
// your row afterwards by adding it to the disabled
// list so that it can no longer be clicked on.
var rowIndex = e.rowIndex;
disabledRows[rowIndex] = true;
// This is just some random class I made up but
// you can use css to stylize the row however you want
var rowNode = e.rowNode;
domClass.add(rowNode, "disabled");
});
Note that domClass is what I named "dojo/dom-class". Hope this helps!
This is perhaps not exactly what you are seaching for:
If you want to hide one or more rows by your own filterfunction you could just add to these rows in the DOM your own class for nodisplay. Here I show you a function for display only those rows which have in a choiceable field/column a value inside your filterlist.
function hideRowFilter(gridId, fieldName, filterList)
{
var store = gridId.store;
var rowId;
store.query(function(object){
rowId = gridId.row(object.id,true).node();
if (filterList.indexOf(object[fieldName]) == -1)
domClass.add(rowId, "noDisplay"); // anzeigen
else
domClass.remove(rowId, "noDisplay"); // verstecken
});
}
CSS:
.noDisplay { display: none; }
So I can for example display only the entries with a myState of 3 or 4 with this call:
hideRowFilter(gridId, 'myState', [3, 4]);
Note that domClass is what I named "dojo/dom-class"
I am working in extjs4. I have grid panel view as=
i want to show image in floating window whenever user clicks on grid row.So i have written function namely showImage() and calling it as=
me.mon(me, {'itemclick' : me.showImageViewer
}, me);
But i dont want to call this function when user clicks on FileName column of grid. So how to restrict calling showImage function when user clicks on grid column 'FileName'
You can listen to the column click function. Define common listener for columns you need. In arguments you should recieve grid, cell element, row index, column index, event data and record(in such order). So if you'll move, rename headers or do whatever you want with column with such listener it wouldn't change click listener.
i want to show image in floating window whenever user clicks on grid row.
Do you mean you'll show a popup containing the bigger image if image on row is clicked? if yes, on your showImageViewer function, you have to check the attributes of the cell if it's an image or you can check its dataIndex.
You can also listen to cellClick instead of itemClick. With that, you can check the cellIndex of the cell being clicked. In your case, if cellIndex is equal to 2 (index of your FileName column, don't call showImageViewer.
cellClick : function(view, cell, cellIndex, record, row, rowIndex, e) {
}
You can use a css selector to differentiate between elements inside the row, using a code like the following
listeners: {
itemclick: {
fn: function (view, record, item, index, e, eOpts) {
var photo = e.getTarget('.photo');
if(photo) {
alert(record.get('photo'));
}
}
}
You can try a working sample here. Hope it helps to solve your problem
I have an an array of objects. I populate the datagrid from the array. The nmber of columns in the datagrid is fix i.e.5 and the first column always shows serial number (0,1,2,3,4).
I have a link button called 'CLEAR' in the last column of the datagrid.
1> How do I make the clear button visible only when the row is particularly clicked ?
2> When the clear button is clicked, how do I make the contents of that particular row cleared. Not deleted, only cleared to insert data again. Also, the serial number (0,1,2,3,4) should not be cleared, nor deleted. How to do this ?
To make your clear button visible something like this would work.
may have to play around with it a bit.
private function onDatagridClick(event:ListEvent):void {
if ( event.rowIndex == -1 ) {
return;
}
clearBTN[event.RowIndex].visible = true;
}
If you don't want to delete your column you need to place some data in there as the datagrid is bound by the data provider you can always add dummy data i.e. blank string, "Enter data" or a custom item renderer for when data is required.
