How can tick check box in datagridview with mouse click?

1.Add Itemplate as label
and call javscript function on onclick event of label with passing id of this label.

code:

<ItemTemplate >
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company")%>' onClick="return FunctionName(event,this);" contentEditable="true"></asp:Label>
</ItemTemplate>


javscript:
fucntion functionname(e,ctrl)
{

//from this you can get current row index and cellindex by using this you can make

var row=ctrl.offsetParent.parentNode.rowIndex;
var cell=ctrl.offsetParent.cellIndex;

var gdv = document.getElementById('GridView1');
gdv.rows(row).cells(column number of your checkbox column).children.item(0).checked=true;

}



Or

2.you directly call javascript function on gridview click

code:

<asp:GridView ID="GridView1" runat="server" Width="80%"  onClick="return return FunctionName(event,this);" >

javscript:

fucntion functionname(e,ctrl)
{

var gdv = document.getElementById('GridView1');

//from this you can get current row index and cellindex by using this you can make

var row=ctrl.document.activeElement.parentElement.rowIndex;
var cell=ctrl.document.activeElement.cellIndex;

gdv.rows(row).cells(column number of your checkbox column).children.item(0).checked=true;

}

I hope it helps you
