  Confirmation on DataGrid "Delete" LinkButton

  Feb 26, 2013 10:03 PM|LINK

  Not sure there is a solution out there for the way I'm creating my gridview but I need to have the user confirm deleting the record.

  <asp:GridView ID="grdFiles" runat="server" skin="Default" DataKeyNames="DocId" AutoGenerateColumns="false"
              OnRowCommand="grdFiles_ItemCommand">
              <Columns>
                  <asp:BoundField DataField="DocId" HeaderText="ID" Visible="false" />
                  <asp:TemplateField>
                      <ItemTemplate>
                          <asp:LinkButton ID="lnkbtnView" runat="server" CommandName="View" Width="50px" ForeColor="Red"
                              CausesValidation="False" Text="View">
                          </asp:LinkButton>
                      </ItemTemplate>
                  </asp:TemplateField>
                  <asp:BoundField DataField="FileNames" HeaderText="File Name" />
                  <asp:TemplateField>
                      <ItemTemplate>
                          <asp:LinkButton ID="lnkbtnDelete" runat="server" CommandName="DeleteIt" Width="50px"
                              ForeColor="Red" CausesValidation="False" Text="Delete">
                          </asp:LinkButton>
                      </ItemTemplate>
                  </asp:TemplateField>
              </Columns>
          </asp:GridView>

   List<Facade.File> up = new List<Facade.File>();
              up = FilesQueries.GetAllFiles(SessionManager.AuthenticatedUser, Id);
              grdFiles.DataSource = up;
              grdFiles.DataBind();

   protected void grdFiles_ItemCommand(object sender, GridViewCommandEventArgs e)
          {
              LinkButton lnkBtn = (LinkButton)e.CommandSource;    // the button
              GridViewRow myRow = (GridViewRow)lnkBtn.Parent.Parent;  // the row
              GridView myGrid = (GridView)sender; // the gridview
              int ID = Convert.ToInt32(myGrid.DataKeys[myRow.RowIndex].Value.ToString());
  
  
              switch (e.CommandName)
              {   case "DeleteIt":
  
  // need to confirm delete
  
                     bool success = Facade.FilesTransaction.DeleteFile(SessionManager.AuthenticatedUser, ID);
  
  
                      break;
                  default:
                      break;

  
  
  I'm doing going to search the web some more, maybe I need to change the way I'm creating my grid view.

  Typically the javascript confirm will be used to prompt the user and there are many possible ways to implement it in gridview. Here's a step by step example of different options: http://geekswithblogs.net/dotNETvinz/archive/2009/02/22/display-confirmation-message-on-gridview-deleting.aspx

  If you want more fancy then you can try out this opensource control: MessageBox controls for WebForms. And here's a simple demo: http://geekswithblogs.net/dotNETvinz/archive/2012/02/01/using-proudmonkey-confirmbox-control-in-gridview.aspx

  The OnCleintClick is never called.
