Assign ValidationGroup to RadGrid

[Rob Venable]

Hi,
I have a grid that is editable and I want to assign a ValidationGroup to the Delete and Update functionality so that it doesn't interfere with the other controls on the page. How do I set the ValidationGroup on these controls?
Here are my Edit and Delete Grid Command Columns:

<telerik:GridEditCommandColumn  ButtonType="ImageButton" UniqueName="EditCommandColumn">
        <HeaderStyle HorizontalAlign="Center" Width="30px" />
        <ItemStyle CssClass="MyImageButton" HorizontalAlign="Center" />
    </telerik:GridEditCommandColumn>
    <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
        ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
        UniqueName="DeleteColumn">
        <HeaderStyle HorizontalAlign="Center" Width="30px" />
        <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton" />
    </telerik:GridButtonColumn>

I tried using ValidationGroup but it doesn't recognize it as a property for these columns. It happens when I hit the Delete column and when I hit the Update link after clicking the Edit column..

Thanks

Hi,

Try the code snippet below to access  the controls for edit and delete accordingly:

C#

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editedItem = (GridEditableItem)e.Item;
            ((ImageButton)editedItem.FindControl("UpdateButton")).ValidationGroup = "GroupA";

        }
        if (e.Item is GridDataItem)
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            ((ImageButton)dataItem["DeleteColumn"].Controls[0]).ValidationGroup = "GroupA";
        }
    }

Thanks,
Princy

That is a design bug! I need to write code to set the ValidationGroup?

A much better way will be something like that:

        <telerik:GridEditCommandColumn                   
          ValidationGroup="GroupXY"
          ButtonType="ImageButton"
          />

Telerik - can you please fix that?
I see no reason why a ValidationGroup is needed for a delete buttom?

Kind regards,
Sörnt

Hello Sörnt,

You can simply set:

<ValidationSettings EnableValidation="true" ValidationGroup="SomeGroup"/>

RadGrid will propagate the validation setting to all built-in buttons.

All the best,
