RadGrit with DataTable as Datasource. No Columns in the Grid

[Gunther]

Hello,

 

if i bind a RadGrid with a DataTable as DataSource.
There are no columns in the RadGrid only the DataSource had some.

Displaying the data works.

 

I have to let the user group the columns. It don't work if there are none.

GridColumnGroup colGrp = new GridColumnGroup();
            colGrp.Name = TextBox1.Text;
            colGrp.HeaderText = TextBox1.Text;

            RadGrid1.MasterTableView.ColumnGroups.Add(colGrp);

            RadGrid1.MasterTableView.Columns[0].ColumnGroupName = TextBox1.Text;
            RadGrid1.MasterTableView.Columns[1].ColumnGroupName = TextBox1.Text;

 

Please take a look at the added pictures.

Hi Gunther,

I tried to replicate the behavior you describe, however, I was not able to. Please check the attached sample that I used for testing.

The RadGrid in the sample is data-bound to a DataTable filled with dummy data. The functionality is working as expected on my end. Give the sample a try and let me know what should be modified in order to replicate the behavior you are seeing.
