ComboBoxEditorSettings and Cell Edit Mode

[Ludovic Gerbault]

Hello

I created a GridViewDataColumn set with a ComboBoxEditorSetting.

What I'd like to do is when my grid gets the focus, I want the first cell of the first row (wich is my ComboBox) to enter in edit mode and I want to set the IsDropDownOpen property to true.

I've managed the first part, but I'm getting stucked with the second one (I can't get the RadComboBox in the GridViewCell)

Here's what I've wrote from a piece of code in this forum

	private void FormGrille_GotFocus(object sender, RoutedEventArgs e)
	{
	FormGrille.GotFocus -=new RoutedEventHandler(FormGrille_GotFocus);
	DataRecord record = (DataRecord)this.FormGrille.Records[0];
	var element = (GridViewRow)this.FormGrille.ItemsControl.ItemsGenerator.GenerateItemAtIndex(record.DataSourceIndex);
	((GridViewCell)element.Items[0]).IsInEditMode = true;
	}

Any ideas, anyone ?

Please, I'm still stucked on this one.

Hi Subileau Pascal,

This is quite a specific scenario and is unfortunately not supported by the internal logic of the ComboBoxColumn and the ComboBoxEditorSettings.

Indeed there is no way to get the ComboBox editor  as it loads on demand after the cell has entered edit mode. To serve such scenario , we have scheduled to add an EditorLoaded event to the RadGridView for our very next official version.

Meanwhile there is a kind of solution:

Since GridViewComboBoxColumn does not help much here , you may use  a templated GridViewColumn.

You may place a ComboBox within the cell template and manually bind it to data and respond to selection changes, update datasource etc.
