Hi All,

I am using the wrong argument for Selection() function. I should use as follow. Now function return false if selected row index and disabled checkbox index but still can select the row and check box is checked. Please let me know. Thanks.

function Selecting (sender, eventArgs)

{

var i = 0;

while(typeof(a[i]) != "undefined")

{

if (a[i++] == eventArgs.get_itemIndexHierarchical())

{

return false;

}

}

}

Solved.

using 

eventArgs.set_cancel(

true) instead of return false.
