I have set up a grid panel with groupingsummary (tried grouping feature also - no luck) feature and actioncolumn [for deleting and editing records]. I'm wrestling a couple of days to get row index but to no avail.
Without the groupingsummary feature the actioncolumn works as it should, i can edit or delete a row by clinking the action icons using the following code to select a row:
handler: function(grid, rowIndex) {
rec = grid.getStore().getAt(rowIndex);
rowId = rec.get('rowId');
rowName = rec.get('rowName');
...
...
}
Then i execute an Ajax request to the server for the corresponding action [edit, delete].
How do i select a row in a grid with groupingsummary feature? Is it a bug?

I would like to add new row in table field if I press tab on the last column of the last row.
If user press tab on cell (editable cell) it select next cell in row or go in new (existing) row. But I would like to achieve that if I press tab on last row with last column that this action would create new row. Currently it focus next button/field/... in form.
Is there a way to do this?
Have you tried to use something like this:
Add on the last Column a execCompleteEdit and check if you are in the last row
#Override
protected void execCompleteEdit(ITableRow row, IFormField editingField) {
if (row.getRowIndex() == row.getTable().getRowCount() - 1) {
// create row
ITableRow r = row.getTable().addRow(getTable().createRow());
//eventually you have to set values into cells
//get first editable cell(in this case NameColumn) and request focus
row.getTable().requestFocusInCell(getNameColumn(), r);
}
}
It is a standard QTableWidget
All cells are QTableWidgetItem.
All cells are editable/selectable
Question: How can I modify all the cells I have selected?
Possible way is to use the dialog open. So the idea is like this :
Select the items
Make a button or something to open input dialog.
Apply the value of input dialog to all selected items.
I was facing a similar problem a couple years ago and I solved it like this:
I have inherited my own view and I have reimplemented methods commitData() and mouseReleaseEvent().
commitData takes all selected indices from the selection model and calls QAbstractItemModel::setData() for all of them. Data are taken from the editor like this:
QByteArray n = editor->metaObject()->userProperty().name();
if (n.isEmpty())
n = delegate->itemEditorFactory()->valuePropertyName(model()->data(index, Qt::EditRole).userType());
if (!n.isEmpty())
{
QVariant data = editor->property(n);
for (const QModelIndex & idx : selectedIndices)
{
model()->setData(idx, data);
}
}
mouseReleaseEvent() performs three steps:
Get a current selection from the selection model.
Call original event handler (QTableWidget::mouseReleaseEvent())
Restore selection: QItemSelectionModel::select()
I've been searching for similar solutions out there but am coming up short so far. Here is what I want to accomplish:
I need to come up with a basic solution to sync inventory quantities at the end of each day. We take physical counts of inventory sold throughout the day but need something to log these changes and share between users. I would like to utilize two buttons (click one to subtract amount of items sold at the end of the day and click one button to add newly received inventory).
This is how my sheet is set up:
Col A: Product Tag
Col B: Product sku
Col C: Amount Sold Today
Col D: Total Inventory Quantity
Col E: Add New Inventory
Column D will be pre-populated with initial inventory counts. At the end of each day, I would like to go down my product list and fill in the amount of each item sold that day in Column C. Once Column C is fully populated, I would like to click the "subtract" button and have Column C subtracted from Column D.
On the other side, once we receive new stock of an item I would like to enter these counts into Column E. Once this column is fully populated, I would like to click the "Add" button and have Column E added to Column D. Ideally once the add or subtract function has been completed, columns C or E will be cleared and ready for the next days entry.
I already have designed my buttons, I just need help coming up with the scripts to accomplish this.
You can use Google Apps Script for this.
If you are unfamiliar, in your particular spreadsheet, go to Tools → Script Editor and then select the Blank Project option.
Then you can write functions like this to achieve what you want!
function subtractSold() {
var sheet = SpreadsheetApp.getActiveSheet();
var c1 = sheet.getRange("C2");
var c2 = sheet.getRange("D2");
while (!c1.isBlank() && !c2.isBlank()){
c2.setValue(c2.getValue() - c1.getValue());
c1.clear();
c1 = c1.offset(1, 0);
c2 = c2.offset(1, 0);
}
}
Basically what the function does is:
Get a reference to the active spreadsheet
Get references to the cells C2 and D2, for the first row of data.
Use a while loop to repeated go through the rows. Terminate when either cell is empty.
In the loop, we get the appropriate values, subtract and set the value back into the cell. Then we clear the cell in column C. We then move both cell references down by one row (the offset method returns a reference to the original cell, but offset by row, column).
Then assign the script to the button image by entering the name of the function (subtractSold in this case) in the "Assign script" option for the button.
I have made an example sheet here (go to File → Make a Copy to try the scripts and see the code): https://docs.google.com/spreadsheets/d/1qIJdTvG0d7ttWAUEov23HY5aLhq5wgv9Tdzk531yhfU/edit?usp=sharing
A bit faster
If you try the sheet above you can see it processes one row at a time, which might get pretty slow when you have a lot of rows. It is probably faster to process the entire column in bulk, but it may be a bit more complicated to understand:
function subtractSoldBulk() {
var sheet = SpreadsheetApp.getActiveSheet();
var maxRows = sheet.getMaxRows();
var soldRange = sheet.getRange(2, 3, maxRows); // row, column, number of rows
var totalRange = sheet.getRange(2, 4, maxRows);
var soldValues = soldRange.getValues();
var totalValues = totalRange.getValues();
for (var row in soldValues) {
var soldCellData = soldValues[row][0];
var totalCellData = totalValues[row][0];
if (soldCellData != "" && totalCellData != "") {
totalValues[row][0] = totalCellData - soldCellData;
soldValues[row][0] = "";
}
}
soldRange.setValues(soldValues);
totalRange.setValues(totalValues);
}
The difference here is that instead of getting one cell, we get one range of cells. The getValues() method then gives us a 2D array of the data in that range. We do the calculations on the two arrays, update the data in the arrays, and then set the values of the ranges based on the array data.
You can find documentation for the methods used above from Google's documentation: https://developers.google.com/apps-script/reference/spreadsheet/sheet
LATEST UPDATE: Issue answered here. Some one else at stackoverflow had a similar issue and it was resolved. Solution provided for convenience. This is the line of code I was missing:
comboHeaderColumn.useLabelFunctionForFilterCompare = true;
that line is followed by these:
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
comboHeaderColumn.labelFunction = formatState;
where formatState is a local method that formats the data for the combobox.
UPDATE: I've now got the combobox's loading with the correct data, but when I select a value nothing happens. The combo boxes load only data that is in the column, and when you select a value in the combobox, it's supposed to filter the rows on that value. It doesn't.
Thanks for looking. I'm having trouble getting multiple filters to work in Flex in Flash Builder 4 using the ExtendedDataGrid and ComboBox's. Here is an image of part of the grid:
The User Name and City filter properly if you type text into the box's above the column header and the Request Date lets you select date ranges if you click on the Custom bar, but the Request Reason and State ComboBoxes do not list anything. I've created them using comboHeaderColumn.filterComboBoxBuildFromGrid = true; but all it does is put "[object Object]" as the only other selection under All.
I've used this article but it will only allow you to use a single filter for the entire grid.
My finished grid will have about 20 columns and from 20,000 to 450,000 rows of data so the filters are really important and I'll need more than one.
The code is very straight forward and loops through all the returned data and if the column is identified as a filter column it does this:
comboHeaderColumn.filterComboBoxDataProvider = codeValuePairs;
comboHeaderColumn.filterComboBoxLabelField = "Value";
comboHeaderColumn.filterControl = "ComboBox";
comboHeaderColumn.filterOperation = FilterExpression.FILTER_OPERATION_TYPE_EQUALS;
comboHeaderColumn.headerText = ac.Header;
comboHeaderColumn.dataField = ac.Name;
if( ac.Header == "State" || ac.Header == "Request Reason" )
{
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
}
ProfileDataColumns.push(comboHeaderColumn);
This creates 2 entries in the combo box: All and [object Object]
What am I missing??? Anyway, after half a day searching I decided to reach out.
Any suggestions or direction to an article would be very much appreciated.
Thanks.
I'm creating a table that displays information from a MySQL database, I'm using foreignkeys all over the place to cross-reference data.
Basically I have a datagrid with a column named 'system.' The system is an int that represents the id of an object in another table. I've used lableFunction to cross-reference the two and rename the column. But now sorting doesn't work, I understand that you have to create a custom sorting function. I have tried cross-referencing the two tables again, but that takes ~30sec to sort 1200 rows. Now I'm just clueless as to what I should try next.
Is there any way to access the columns field label inside the sort function?
public function order(a:Object,b:Object):int
{
var v1:String = a.sys;
var v2:String = b.sys;
if ( v1 < v2 ){
trace(-1);
return -1;
}else if ( v1 > v2 ){
trace(1);
return 1;
}else {
trace(0);
return 0;
}
}
One way to handle this is to go through the objects you received and add the label as a property on each of them based on the cross-referenced id. Then you can specify your label property to display in your data grid column instead of using a label function. That way you would get sorting as you'd expect rather than having to create your own sort function.
The way that DataGrids, and other list based classes work is by using itemRenderers. Renderers are only created for the data that is shown on screen. In most cases there is a lot more data in your dataProvider than what is seen on screen.
Trying to sort your data based on something displayed by the dataGrid will most likely not give you the results you want.
But, there is no reason you can't call the same label function on your data objects in the sortFunction.
One way is to use the itemToLabel function of the dataGrid:
var v1:String = dataGrid.itemToLabel(a);
var v2:String = dataGrid.itemToLabel(b);
A second way is to just call the labelFunction explicitly:
var v1:String = labelFunction(a);
var v2:String = = labelFunction(b);
In my experience I have found sorting to be extremely quick, however you're recordset is slightly larger than what I usually load in memory at a single time.
