Hi, I'm implementing gridview crud operation. I used command field with button type button, all the functions (edit, update,delete) worked properly. But when I changed command field button type to image, delete function is not firing. When I click on Delete icon, Javascript alert is coming, and when I click ok, it is not firing OnRowDeleting function, Below is my code
  1. <asp:GridView ID="grdCenterVisitDate" runat="server" AutoGenerateColumns="false" OnRowDataBound="OnRowDataBound"  
  2. DataKeyNames="CenterVisitID" OnRowEditing="OnRowEditing" OnRowCancelingEdit="OnRowCancelingEdit" PageSize = "5" AllowPaging ="true" OnPageIndexChanging = "OnPaging"  
  3. OnRowUpdating="OnRowUpdating" OnRowDeleting="OnRowDeleting" EmptyDataText="No records has been added."
