[Solved] GridViewComboBoxColumn only in insert mode

[Michele]

Hello Telerik,
it's possible to have the combobox only in the InsertRow mode and as a textbox in normal and edit mode?
Thanks

Hello Paolo,

It is not internally supported, but with a small hack , it can be done.

You may place a small user control in the CellEditTemplate. In the code behind , when loading the user control you may check if the parent is GridViewRow or GridViewNewRow and conditionally show/hide the editor.

Let me know if you need sample code on that .

Kind regards,

Hello Paolo,

In the sample attached , i have tried to resemble the scenario -

When the user presses Insert - a new row appears with a combo editor,
When a regular row is edited - a textbox editor is shown .

In case you find further troubles with this, just let me know.

Thanks

Hi Paolo,

You can use binding to pass the ItemsSource to the combo inside the user control.

For this you will need.

1. Expose an ItemsSource property on the user control wrapping the combo ( this property should be bound to the items source of the internal combo

2. In the CellEditTemplate , you may then bind the new property to the list of items for the combo.

3. To be able to use binding , you will need to expose the list as a static resource , and then in the cell edit template use syntax like :

ItemsSource= {Binding , Soruce={StaticResource  ......

Let me know if you need me to extend  the example to cover this as well.
