The Final Guide

While working with inventory screens or multiple items of any category, we often need to face situation of representing the items in ASP.Net GridView on a webpage providing CheckBox to select single or multiple items. CheckBox control can’t be placed in a column of GridView directly, in which case it must be embedded in an ItemTemplate column of the ASP.Net Gridview.

Design Source

<asp:GridView ID="grvItems" runat="server" AutoGenerateColumns="False" DataKeyNames="ItemNo">
  <Columns>
    <asp:BoundField DataField="ItemName" HeaderText="Name" />
    <asp:BoundField DataField="Description" HeaderText="Description" />
    <asp:TemplateField HeaderText="No" InsertVisible="False">
      <ItemTemplate>
         <asp:CheckBox ID="chkItemNo" runat="server" Text='<%# Eval("ItemNo") %>' />
       </ItemTemplate>
    </asp:TemplateField>
  </Columns>
</asp:GridView>

Coding

C#]
foreach (GridViewRow gvRow in grvItems.Rows)
{
CheckBox chk = (CheckBox)gvrRow.FindControl("chkItemNo");
if (chk.Checked)
  {
    Do_Something_edit_delete_update(grvItems.DataKeys[gvRow.RowIndex].Value);
  }
}

[VB]
For Each gvRow As GridViewRow In grvItems.Rows
  Dim chk As CheckBox = DirectCast(gvRow.FindControl("chkItemNo"), CheckBox)
  If chk.Checked Then
    Do_Something_edit_delete_update(grvItems.DataKeys(gvRow.RowIndex).Value)
  End If
Next
