How to disable reordering specific column?

[Raymond]

Hi

RadGridView has property AllowColumnReorder.

How can I disable reordering specific column?

 

In my case I don`t want let user move first column, all other columns can be reordered.

Hi Raymond,

Hope you're well.
This should stop the first column being re-ordered

this.radGridView1.Columns.CollectionChanging += new NotifyCollectionChangingEventHandler(Columns_CollectionChanging);

private void Columns_CollectionChanging(Object sender, NotifyCollectionChangingEventArgs e)
{
    if (e.Action == NotifyCollectionChangedAction.Move)
    {
        if (e.OldStartingIndex == 0)
        {
            e.Cancel = true;
        }
    }
}

Hope that helps
Richard

Hi again Raymond,

Actually, the below works better... the above would fail if you re-order one of the other columns to the 0 indexed position.

  this.radGridView1.Columns.CollectionChanged += new NotifyCollectionChangedEventHandler(Columns_CollectionChanged);
private void Columns_CollectionChanged(Object sender, NotifyCollectionChangedEventArgs e)
   {
       if (this.radGridView1.Columns["Id"].Index != 0)
       {
           this.radGridView1.Columns.Move(this.radGridView1.Columns["Id"].Index, 0);
       }
   }

However, the limitation to this is that if you pin a different column to the left, then it will still replace the 0 indexed column.

I changed your code a little:

if (e.Action == NotifyCollectionChangedAction.Move)
{
    if ((e.OldStartingIndex == 0) || (e.NewStartingIndex == 0))
    {
        e.Cancel = true;
    }
}

and it works fine.

Thanks for help.

Yep, that would do it. Glad I could help
All the best

Hello Shashikant,

Thank you for writing.

This forum concerns RadControls for WinForms, and your question seems to be unrelated to it. Please address it to the appropriate forums: RadGridView for ASP.NET AJAX.
