ExpandCollapseColumn Display/Visible

[Lucania]

I've found quite a few threads talking about the Display and Visible properties of ExpandCollapseColumn. Several describe work-arounds for hiding this column, but none explain why 2 properties which the documentation says should show/hide the column seem to do nothing at all.

Please, either make sure these properties do what the documentation says, or fix the documentation. I should not have to write code to do what the documentation says can be done by setting a property.

Thanks

Hi Ross,

I tried to reproduce the described issue, but to no avail. The Visible and the Display properties works exactly as it described into our documentation:

Visible property  gets or sets a value indicating if the column and all corresponding cells would be rendered.
Display property gets or sets a value indicating whether the cells corresponding to a column would be rendered with a 'display:none' style attribute (end-user-not-visible). To completely prevent cells from rendering, set the GridColumn.Visible property to false, instead of the Display property.

Also please note that the GridExpandColumn is an automatically generated and automatically placed column that appears when the grid has a hierarchical structure.More information you could find here:
http://www.telerik.com/help/aspnet-ajax/grid-structure-overview.html (GridExpandColumn section)

I am sending you a simple example which demonstrates that. Also on the following link I attached a small video which demonstrates how the example works on my side.

Please check it out and let me know if it helps you.

Apologies, my post sounded a bit terse.

Thanks for your example and video. They both use back-end code to set the property, and that is how I currently do it. What I was referring to is the ExpandCollapseColumn item within MasterTableView and GridTableView in the front end. If I put:

<ExpandCollapseColumn Visible="false" />

in the front end, I expect the column to not be rendered, but that is not the case. Setting Display="false" likewise appears to have no effect.

I am using version 2011.1.519, maybe this issue has been fixed since then?

Hello Ross,

Try the following CSS to hide ExpandCollapseColumn.
CSS:

.rgExpandCol
{
   display:none !important;
}

Hi Ross,

Indeed I verified the described issue exists in the current version of RadGrid, however I forwarded it to our developers. At a meantime to avoid the described exception you could try using the suggested approaches in the previous posts.
