I'm trying to set a column to be the row's detail column.  I am having trouble using the code as implemented in the demo.

            this.radGridView.DetailsColumn = this.radGridView.Columns["Notes"];

I am getting the error that the radgridview object does not contain detailscolumn.

Hi Mark,

Have a look at my Code Library Project which gives an extended version of the RadDetailsGrid and is available in both C# and VB.NET. You can use it as a control to just drag on like a standard RadGridView and you just need to tell it your Details column,

Hope that helps but let me know if you have any questions

Thanks,
I'll give it a look on Monday, I'm creating the grid at runtime for now, but the design view is nice to have, too.

Hi Mark,

Ok, let me know how you get on. You can still instantiate this grid and build it at runtime and use t as a standard radgridview if you so wish too.
Have a good new year

Hello Mark,

Richard has pointed you to a very nice article that he had created. Do not hesitate to write back in case you need additional assistance.

This is a fantastic project to be sure but I had no end of problems getting it to work.  I don't use databound grids so that might be the root of the problem but I even went as far as creating dummy classes (like you have in your sample projects) and those didn't work.  Pretty soon, the very first cell of the very first row stopped displaying too.

I'd be happy to send you my code but it's a virtual replica of your sample project - the only difference being I had 10 columns instead of 5 and of the 10 only 4 were "visible" so that might be the culprit.  Anyway I wanted to say thank you for this project because I'm sure once I become better than a Novice with the Grid control, i'll be able to debug whatever the issue is and figure out a work-around.

 

Lastly - you should check to see if ColumnDetails is Nothing in ShowRowDetails property of GridViewRowDetailsExtended.  Anyone using this as their standard grid WITHOUT a detail column and this'll crash the ap:

Change:

Set(ByVal value As Boolean)
     m_ShowRowDetails = value
     Me.DetailsColumn.IsVisible = value
     TableElement.Update(GridUINotifyAction.Reset)
     TableElement.UpdateView()
End Set

 

To:

Set(ByVal value As Boolean)
     m_ShowRowDetails = value
     If Not IsNothing(Me.DetailsColumn) Then Me.DetailsColumn.IsVisible = value
     TableElement.Update(GridUINotifyAction.Reset)
     TableElement.UpdateView()
End Set

 

Kindest regards and again, this is pretty outstanding (even with my issues, I'm fairly certain I'm the cause of the problems and not your modifications.)
