How to hide a column?

[Todd Davis]

This seems like it should be an easy thing, but I'm hitting roadblocks all over the place.

I have a RadGridView inside of a User Control that I use on more than one page. The first column of the RadGridView is a GridviewSelectColumn, however, in certain situations, I don't want this column to appear.

The first thing I tried to do was Name it, then hide it:
<grid:GridViewSelectColumn x:Name="SomeName" />
(in Load Event)
SomeName.IsVisible = false;

But this fails because SomeName always comes up as null.

Then I tried creating a public property and trying to bind it to the column:

<grid:GridViewSelectColumn IsVisible="{Binding IsHidden}" />
(in code behind)
public bool IsHidden{ get; set; }

This did not seem to work either.

How the heck do I hide this conditionally?

Hi,

You cannot access grid columns by Name since columns are not FrameworkElements. Again because of this you cannot bind column properties since Binding is supported only for FrameworkElements - grid columns are plain DependencyObjects. You can access this column however using grid columns collection - by UniqueName, by index or even by type:

var column = RadGridView1.Columns["YourUniqueName"];

or

var column = RadGridView1.Columns[0];

or

var column = RadGridView1.Columns.OfType<GridViewSelectColumn>().FirstOrDefault();
