Hi all

I have a very wide grid, I am using Header Context Menu to Hide/Show the columns then I save the settings of the grid using GridSettingsPersister mentioned in the help.

My problem is that when I hide columns, save settings, and on the next time I load the settings and apply it on the grid, then I show some hidden columns(using header context menu, the grid does not resize, instead, with width of the other columns decreased. I used: TableLayout="Fixed", but It did not work. The width of the grid and master MasterTableView is calculated on GridSettingsPersister as follows:

            double totalWidth = 0; 
 
            foreach (GridColumn column in gridInstance.MasterTableView.Columns) 
            { 
                Triplet triplet = new Triplet(); 
                
                    triplet = dict[column.UniqueName]; 
                    Unit width = (Unit)triplet.Second; 
                    column.OrderIndex = (int)triplet.First; 
                    column.HeaderStyle.Width = width; 
                    column.Display = (bool)triplet.Third; 
 
                    if((bool)triplet.Third) 
                        totalWidth += width.Value;                    
                 
               
            } 
            gridInstance.Width = Unit.Percentage(totalWidth); 
            gridInstance.MasterTableView.Width = Unit.Percentage(totalWidth); 

Settings the width to 100% does not fix the issue, also leaving it empty.

Hello idwaikat,

Does enabling the column resizing for the control and setting ResizeGridOnColumnResize = true produces the desired result? You can see the effect on the following online demo of the product:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/resizing/defaultcs.aspx

Additionally, I think that using TableLayout = Auto is more appropriate in this case (to make the grid auto-size based on the cell content width).

Setting ResizeGridOnColumnResize = true  does not fix the issue, I used it before, also I tried TableLayout = Auto, it did not fix it too. Also I saw your example before, it shocked me, I made exactly the same settings, but your demo differs from my project, because my project contains HeaderContextMenu, which makes the problem more bigger... becuase hiding/showing columns devastate the grid width.. that's the major point (HeaderContextMenu).
