Prevent grouping when edit/insert

[JP]

Hello,

I want to prevent the user from grouping when the grid is currently in edit or insert mode.
For the sort command, I did this in GridItemCommand:

public bool IsInEditMode
      {
         get { return MasterTableView.IsItemInserted || EditItems.Count > 0; }
      }


private void _GridItemCommand(object sender, GridCommandEventArgs e)
{
     if (IsInEditMode &&
             e.CommandName == RadGrid.SortCommandName)
         {
            e.Canceled = true;
         }

But the grouping won't call the GridItemCommand event handler. How can I cancel the grouping?

Hi,

Please try the following code snippet to prevent Grouping on edit/Insert.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        RadGrid1.GroupingEnabled = false;
        RadGrid1.ShowGroupPanel = false;
    }
}

Thanks,
Shinu.

Hi,

this will indded disable the grouping, but when the grid leaves the edit mode, the grouping panel is still disabled although the Grouping gets enabled in OnLoad (including ShowGroupPanel=true).

Hi,

Please try the following code snippet as well.

C#:

protected void Page_Load(object sender, EventArgs e)
{
   RadGrid1.GroupingEnabled = true;
   RadGrid1.ShowGroupPanel = true;
}

Thanks,
Shinu.

The second snippet works, but after a postback (e.g. in the edit form) the Grouping gets enabled again.
It seems that I need to disable the GroupingPanel/GroupPanel in a method which will get called during every postback. Would the Grid's PreRender event handler be the best place for this?

Hi,

Please try the following code snippet in the PreRender event.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
         RadGrid1.GroupingEnabled = true;
         RadGrid1.ShowGroupPanel = true;
         RadGrid1.Rebind();
}

Thanks,
Shinu.
