Loop through RadGrid and read Check Boxes when not in edit mode

by ebarcza 10/10/2017 8:17:00 AM

Step 1 - create a GridTemplate Column with a checkbox

 <telerik:GridTemplateColumn UniqueName="colCheckDelete" HeaderText="Delete">
                    <ItemTemplate>
                        <asp:CheckBox ID="chkDelete" runat="server" />
                   </ItemTemplate>

 </telerik:GridTemplateColumn>

Step 2 - The codebehind loop

foreach (GridDataItem item in rgDeals.MasterTableView.Items)
        {
            CheckBox chkDelete = (CheckBox)item["colCheckDelete"].FindControl("chkDelete");
            if(chkDelete.Checked)
            {
                //Delete the deal
                try
                {
                    int dealID = Convert.ToInt32(item.GetDataKeyValue("DealID"));
                    string sql = "Delete stuff where dealID = " + dealID;
                    int rslt = Utility.ExecuteNonQuerySQL(sql);
                }
                catch (IndexOutOfRangeException ex)
                {
                    //do nothing
                }
                catch (Exception ex)
                {
                    ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "alert", "CreateMasterAlert('alert alert-danger', '" + "One or More deletes failed" + "');", true);
                }
            }
        }
        rgDeals.Rebind();
        ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "alert", "CreateMasterAlert('alert alert-success', '" + "Delete Operation completed" + "');", true);
