[Solved] Add/Remove Column

[John]

I have a grid that has 6 columns on it by default.  I then allow the user to add/remove other columns at run time.  The add works well however if they add a column and then attempt to remove that column only the Header for the column actuall get removed.

Eaxmple the user selects a checkbox that adds State column to a grid.  I add the column, set the datafield and uniquename.  ReBind the grid and all is good.  The user the deselects the State checkbox so I attempt to remove the column by finding that column with the unique name, do a Remove (I have also tried getting column and using RemoveAt) and a rebind.  The header for State is now gone but all the actual rows are still populated with the state data.  If the then attempt to add State again a new column is created with the state info and the previous column now shows System.Collection.Dataobject still with no header.

Any assitance would be welcome.

Thanks

Hi John,

RadGrid does not support mixed column load i.e. part of the columns defined in .aspx and another part added programmatically, as mentioned here. You can toggle the Visible property of the column, I have attached a small page showing this. Alternatively, you can check this help topic dedicated to changing the grid structure on postback.
