How can I uncheck the check box column (Column Header) programatically.

[Pradeep Kumar]

Hi,

I have a DataBoundGrid which contains checkbox as one of the Header column. when i check that check box then all the check boxes in that column will be checked. similarly when i uncheck that, all the check boxes in that column will be unchecked.
The problem i got is when i check the check box in the header then all the check boxes will be checked it is o.k, but when the datasource of that grid is made null, all the data will be cleared, then also the check box in the column header is checked. How can i uncheck the checkbox through programatically.


-Thanks
Deepak

Hi,
Thanks for your samples. The sample works fine to check or uncheck the checkboxes dynamically which are in the grid. Here my requirement is how can i uncheck the check box which is defined as a column header dynamicaly. which means i want to change the column header value dyanamically.

Thanks

Here is that sample modified to allow you to change the CheckBoxValue for the header cell in the GridDataBoundGrid from a button handler.
