After completion table creation enter some dummy and design your aspx page like this
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Delete Rows in Gridview with Checkbox</title>
<style type="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
color:black;
}
</style>
<script type="text/javascript">
function Confirmationbox() {
var result = confirm('Are you sure you want to delete selected User(s)?');
if (result) {
return true;
}
else {
return false;
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvUserDetails" runat="server" DataSourceID="objUsers"
DataKeyNames="UserId" CssClass="Gridview" AutoGenerateColumns="false"
HeaderStyle-BackColor="#61A6F8" HeaderStyle-Font-Bold="true"
HeaderStyle-ForeColor="White">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkdelete" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="UserName" HeaderText="UserName" />
<asp:BoundField DataField="FirstName" HeaderText="FirstName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" />
<asp:BoundField DataField="Location" HeaderText="Location" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="objUsers" runat="server" ConnectionString="<%$ConnectionStrings:dbconnection%>"
SelectCommand="select * from UserInformation"
DeleteCommand="delete from UserInformation where UserId=@UserId" >
<DeleteParameters>
<asp:Parameter Name="UserId" Type="Int32" />
</DeleteParameters>
</asp:SqlDataSource>
</div>
<asp:Button ID="btnDelete" runat="server" Text="Delete" onclick="btnDelete_Click" />
</form>
</body>
</html>
................................. .cs ...................
protected void Page_Load(object sender, EventArgs e)
{
btnDelete.Attributes.Add("onclick", "javascript:return Confirmationbox()");
}
protected void btnDelete_Click(object sender, EventArgs e)
{
//Loop through all the rows in gridview
foreach(GridViewRow gvrow in gvUserDetails.Rows)
