White space between columns

[Eugene]

Hello!
I'm having an issue with empty space between two columns, when the column between them is hidden.
I changed the order and width of columns.
This simple project demonstrates the problem (https://1drv.ms/u/s!AvjI7FUHDKc8bN-uiEV4lHRS67s ).

Hello Sergei,

You can avoid the behavior by applying the changes in the columns'  appearance in the DataLoaded event of the RadGridView instead of the AutoGeneratingColumns:

private void gridView_DataLoaded(object sender, EventArgs e)
       {
           foreach (var col in gridView.Columns)
           {
               if (col.UniqueName == "Name")
               {
                   col.Width = 300;
                   col.IsVisible = true;
                   col.DisplayIndex = 2;
               }
               if (col.UniqueName == "Established")
               {
                   col.IsVisible = false;
                   col.DisplayIndex = 1;
               }
               if (col.UniqueName == "StadiumCapacity")
               {
                   col.IsVisible = true;
                   col.DisplayIndex = 0;
               }
           }
       }

We use properties binding, and applying of the changes in the columns' appearance happens before data loads.

Hello Sergei,

Applying the logic through the Dispatcher also works fine:

private void gridView_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
      {
          Dispatcher.BeginInvoke((Action)(() =>
          {
              if (e.Column.UniqueName == "Name")
              {
                  e.Column.Width = 100;
                  e.Column.IsVisible = true;
                  e.Column.DisplayIndex = 2;
              }
              if (e.Column.UniqueName == "Established")
              {
                  e.Column.IsVisible = false;
                  e.Column.DisplayIndex = 1;
              }
              if (e.Column.UniqueName == "StadiumCapacity")
              {
                  e.Column.IsVisible = true;
                  e.Column.DisplayIndex = 0;
              }
          }));
      }

I hope it will be suitable for you as well.
