How to set the minimum width of a column while AllowColumnResize is set to "True"

[Sudha]

Hi,

AllowColumnResize

 

 

="True" in the rad gird. This allows resizing the columns to any width. I want to set a minimum value to which the column width can be reduced. if the user tries to reduce the width of the column lower than what is specified , then the width should be set to the minimum value mentioned.

Kindly let us know if this can be achieved and how.

Thanks,
Sudha.

I would set HeaderStyle > Width for the column in question, Sudha. I think that in this way you should be able to define minwidth for the column when resized.

Thanks.
But we have the width set in the HeaderStyle. It is not working.

Hello,

It was not possible but try with below code snippet.
It was not exactly fulfill your requirement but its helpful to you.

function ColumnResizing(sender, eventArgs) {
             if (eventArgs._gridColumn._data.UniqueName == "YourColumnUNiqueName" && eventArgs.get_gridColumn()._columnResizer._currentWidth < 100) {
                 eventArgs._cancel = true;
             }
         }

<ClientEvents  OnColumnResizing="ColumnResizing" />

Thanks,

Hi Sudha,

You cannot set min/max column widths, but you can use the ColumnResizing client event to check what the new column width would be and cancel/modify it:

After cancelling the event, you can resize the column to a preferred min/max width with the control's API -
