Button Disable

In your datagrid's ItemDataBound(or RowDataBound):
1. You know the number of records to be displayed here (Dataset row count) - X
2. Setup a counter (Y) and track number of rows disabled based on the field that is deciding the checkbox value
3. At the end of the loop, when the data is binded, check if the counter you set is equal to total row count (X==Y?). If so, disable the button on server side. Or else, leave it as it is.

P.S.: The counter that will track number of rows disabled should be global variable and not local.

hello,

I have done in the Grid view.
If any check box is checked then the button outside gridview is Enabled and if not checked then the button is diasabled.

You can modify it and can use.

<script type="text/javascript">
function check(chkB) {
//var IsChecked = alert(document.getElementById(chkB));
if (chkB.checked) {
document.getElementById("ctl00_ContentPlaceHolder1_btnRemove").disabled = false;
}
else {
document.getElementById("ctl00_ContentPlaceHolder1_btnRemove").disabled = true;
}

}
</script>


and on checkbox:

onClick="check(this)"

this will work.


this id in the javascript is buttons runtime id that is created automatically
"ctl00_ContentPlaceHolder1_btnRemove"

my button id is btnRemove,but at runtime thats created.
