Show Total amount for RadGrid when clicking CheckBox

[Lakshman]

How to Display total amount as Label when selecting the check-boxes in the Telerik Rad Grid.  

For example: I have three columns in the grid (Code, Description, Amount) one more column for Check box in each row. By selecting check box the total amount should display as label dynamically. If selects all then display total amount.



Thank you,

Hello,

Try the following code.
ASPX:

<telerik:GridTemplateColumn UniqueName="chkbox" HeaderText="templatecol">
     <HeaderTemplate>
        <asp:CheckBox ID="chk2" runat="server" OnCheckedChanged="chk2_CheckedChanged" AutoPostBack="true"/>
     </HeaderTemplate>
     <ItemTemplate>
       <asp:CheckBox ID="chk1" runat="server" OnCheckedChanged="chk1_CheckedChanged" AutoPostBack="true" />
     </ItemTemplate>
</telerik:GridTemplateColumn>

CS:

protected void chk1_CheckedChanged(object sender, EventArgs e)
   {
       CheckBox chk1 = (CheckBox)sender;
       GridDataItem item = (GridDataItem)chk1.NamingContainer;
       string s = item["ColUniquename"].Text;
       Label lbl1=new Label();
       lbl1.Text=s;
       form1.Controls.Add(lbl1);
   }

//for select all checkbox
   protected void chk2_CheckedChanged(object sender, EventArgs e)
   {
       int i = 0;
       foreach (GridDataItem itm in grid1.MasterTableView.Items)
       {
          string s1= itm["ColUniquename"].Text;
          i = i + Convert.ToInt16(s1);
       }
       Label lbl = new Label();
       lbl.Text = i.ToString();
       form1.Controls.Add(lbl);
   }

Thanks,
Princy.
