I am having a issue when using a cell editing grid that has a field that opens a window. The issue is when you open the editor for the field and click on one of the combobox triggers, a window opens, which causes the field to fire validateedit, resulting in the editor closing. I am looking for a way to prevent this. The reason that I am opening a window is that I am giving the user the ability to quickly add a new record to the combobox, without having to go to another place in the system. I am able to get this functionality to work with row editing but my customer does not like they way row editing works.
Here is my fiddle example.

I have a ComboBox in a DataGridTemplateColumn.CellTemplate. When editing an existing entry the UpdateSourceTrigger=PropertyChanged fires on property change. However, I want it to fire on a new line as well just as if I have press (clicked) in any of the cell to start new entry.
By the way I am not using DataGridTemplateColumn.CellEditingTemplate for editing but DataGridTemplateColumn.CellTemplate which I thinks looks better unlike the default
In MS documentation it says DataGridCell.Selected Event Occurs when the cell is selected. That means when one presses a KeyDown or mouse click in the cell. I guess what I want is how to select a cell through a ComboxBox selection changed event. I want when I select a record in the combobox to begin the a new line just as if I have started typing soemthin in any of the DataGrid cells.
I use AgGrid Enterprise, and allow users to edit an entire row so all cells switch to edit mode.
I also have an event listener to save the row in database when the user put the focus on a new line or outside the grid.
In the first column of my grid, i have a custom cell displaying a combo.
When the user select a value, it should update the cell AND 3 other cells in the row.
So i use the API to refresh the 3 cells.
Doing so put the cell in view mode, i loose the edit mode and the save event is triggered.
Is there a way in edit mode, to update cell content without loosing the edit mode ??
Thanks a lot.
You said your are try to entire row and and also have custom cell with combo
but ag-grid does not work any popup editor with full row edit.
You have to remove ag-grid property editType: 'fullRow' and it will work.

I have a grid with 3 columns and 5 rows.
I have attached a CellEditing plugin to the grid.
And for the 3rd column i have defined an numberfield editior.
So now due to this each row 3rd column has a numberfield editor attached to it.
But due to some condition present in data/column metadata, i want to disable the numberfield editor for 2nd and 4th row.
I am unable to disable cell editor for particular rows as the editor is attached at the column level.
Is there a way in ExtJS to handle this kind of scenario.
I am using ExtJS 5.
As noted in the comments by Evan, you need to use the beforeedit event to veto the edit before it starts.
ExtJS does not attach an editor to every cell. Instead, when the user triggers the edit (e.g. by single- or double-clicking on the grid cell), the CellEditing plugin will be invoked. If the beforeedit event is not vetoed, it will then attach the edit field to the cell in place. When the edit is finished, the edit field will be detached.
If you want to style the non-editable fields differently, to help indicate that they are not editable, the column can be assigned a renderer, which will allow you to provide cell-specific attributes, including CSS style.
I have an infragistics ultragrid control in a windows form. There is an 'Add New' button outside to insert new rows to the grid.
The problem I faced is, when I click the button outside the grid, while I'm editing a cell inside the grid, the cell doesn't lose focus. Because of this the edited new value is not updated to its underlying data source.
I need this cell to lose focus and update it's underlying data source, because the 'Add New' button creates a new row with this particular column having a default value which is calculated based on the previous row's edited value.
So any ideas on how to unfocus the ultragrid cell? This situation may apply to normal GridView also.
If your button is on a Toolbar, then the behavior you are seeing is expected because toolbars don't take focus. If this is the case before performing your logic you can use the PerformAction method of the grid and pass in UltraGridAction.CommitRow to force the row that was being editor to commit its updates.
For example:
this.ultraGrid1.PerformAction(UltraGridAction.CommitRow);
I used myUltraGrid.ActiveRow.Cells[0].Activate(); which also works. But the solution by #alhalama is better one I guess.
I have a silverlight DataGrid, by default on page load the all the cells of the datagrid should be Readonly. I have 2 problem , can any one help me?
1.On Click on the RowHeader the current row should be editable
2. On click of the columnHearder current column of all row should be editable
This might not solve your entire problem but it should partially address it.
This is to make a column read-only in a datagrid
DataGrid.Columns[7].IsReadOnly = true;
Obviously the property can be changed from events but the data grid does not have row/column headers event handlers. Custom controls seem the way to go without introducing any new gui elements like buttons and changing the feel of the application.
