datagrid checkbox

[jithu_hai]

Hi all

I have a datgrid in which I have added three template columns with checkboxes.I have added a push button to the last column and on its button click I am redirecting the page to the same URL with difeeerent querystring parameters.That is if the check boxes are checked then the value passed is 1 other wise zero.The code for it is added in the itemcommand property of datagrid.

Everythhing works fine when I click the button for the first time.But after that nothing happens on button click and the URl remains same.

Please help

Thanks
Sujith
