  Need help with Displaying message in label control in DetailsView within InsertItem Template

  Feb 13, 2016 02:24 PM|Matt99|LINK

  Hi all,

  I have the following html page:

      <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" 
      DataKeyNames="SN" DataSourceID="SafeDescriptionDTS" Height="50px" 
          Width="300px" DefaultMode="Insert" style="text-align: left; float: none" 
                      CellPadding="4" ForeColor="#333333" GridLines="None">
          <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
          <CommandRowStyle BackColor="#E2DED6" Font-Bold="True" />
          <EditRowStyle BackColor="#999999" />
          <FieldHeaderStyle BackColor="#E9ECF1" Font-Bold="True" />
      <Fields>
          <asp:TemplateField HeaderText="Folder Name: " 
              SortExpression="FolderName">
              <InsertItemTemplate>
                  <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("FolderName") %>' 
                      Width="200px" MaxLength="20"></asp:TextBox>
                  <br />
                  <asp:RequiredFieldValidator ID="RequiredFieldtxtBox1" runat="server" 
                      ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="Empty!" 
                      Font-Bold="True" ForeColor="Red" ValidationGroup="DetailsVew1"></asp:RequiredFieldValidator>
                  <asp:Label ID="lblDuplicate" runat="server" Font-Bold="True" ForeColor="Red"></asp:Label>
              </InsertItemTemplate>
              <HeaderStyle Wrap="False" HorizontalAlign="Left" VerticalAlign="Top" 
                  Width="150px" />
              <ItemStyle Width="150px" Wrap="False" />
          </asp:TemplateField>
          <asp:TemplateField ShowHeader="False">
              <InsertItemTemplate>
                  <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" 
                      CommandName="Insert" Text="Insert" ValidationGroup="DetailsVew1"></asp:LinkButton>
                  &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
                      CommandName="Cancel" Text="Cancel"></asp:LinkButton>
              </InsertItemTemplate>
              <EditItemTemplate>
                  <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" 
                      CommandName="Update" Text="Update"></asp:LinkButton>
                  &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
                      CommandName="Cancel" Text="Cancel"></asp:LinkButton>
              </EditItemTemplate>
              <ItemTemplate>
                  <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" 
                      CommandName="Edit" Text="Edit"></asp:LinkButton>
                  &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
                      CommandName="New" Text="New"></asp:LinkButton>
                  &nbsp;<asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="False" 
                      CommandName="Delete" Text="Delete"></asp:LinkButton>
              </ItemTemplate>
          </asp:TemplateField>
      </Fields>
          <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
          <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
          <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
          <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
  </asp:DetailsView>

  Code page:

      protected void SafeDescriptionDTS_Inserted(object sender, SqlDataSourceStatusEventArgs e)
      {
          if (e.Exception != null)
          {
              //Response.Write("<span style='color: red'>Duplicate Folder Name Exists!</span>");
                  Label lblDuplicatex = DetailsView1.Rows[0].FindControl("lblDuplicate") as Label;
                  lblDuplicatex.Text = "Duplicate Folder Name!";
  
              e.ExceptionHandled = true;
  
          }
      }

  When I try to insert a duplicate record the label control does not display the message.

  The code works fine with Response.Write except for findcontrol.

  I appreciate any help.

  Thanks in advance.

  When I try to insert a duplicate record the label control does not display the message.

  The code works fine with Response.Write except for findcontrol.

  Try finding the control like given below

     protected void SafeDescriptionDTS_Inserted(object sender, SqlDataSourceStatusEventArgs e)
          {
              if (e.Exception != null)
              {
                  //// Find control on page
                  Label lblDuplicatex = (Label)DetailsView1.FindControl("lblDuplicate");
                  lblDuplicatex.Text = "Duplicate Folder Name!";
  
                  e.ExceptionHandled = true;
  
              }
          }

  Thanks,

  The page content is inside a contentplaceholder I will need to findcontrol inside the contentplaceholder

  <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

  </asp:Content>

  It is not the content placeholder... But it is the master page is causing the controls not to be detected.

  Hi Matt99,

  Matt99

  Label lblDuplicatex = DetailsView1.Rows[0].FindControl("lblDuplicate") as Label;

  lblDuplicatex.Text = "Duplicate Folder Name!";

  Matt99

  When I try to insert a duplicate record the label control does not display the message.

  Do you debug your code to check whether there are any error with your code? Besides, please make sure you could find “lblDuplicate” control before you assign the text to lblDuplicatex.

  Best Regards,

  Fei Han
