  custom databoundfield with two controls

  Dec 13, 2012 04:51 AM|LINK

  hi,

  i need a custom boundfield inside a grid where i have two controls inside.

  i thought of something like this:

  Public Class MyBoundColumn Inherits BoundField Private name As String Private userId As String Public Sub New() Dim hfUserId As New HiddenField hfUserId.Value = userId Dim lblName As New Label lblName.Text = name cell.Controls.Add(hfUserId) cell.Controls.Add(lblName) End Sub end class

  but as you for sure know this is not working like this.

  i need inside the cell a label or literal where the username is shown, and a hidden field where the userid is the value. the username and userid are both coming from the sql datasource of the grid.

  
  I know there is a way to do this in design view with templates and eval(). But for different reasons i really need it as a class
  i hope this works and you can help.

  thanks :-)

  Hi,

  you need to use RowDataBound event

  example: create a template field in your gridview and add a asp:PlaceHolder shown below

  <asp:TemplateField HeaderText="User Name">
      <ItemTemplate>
             <asp:PlaceHolder ID="PlaceHolder" runat="server"></asp:PlaceHolder>
       </ItemTemplate>
  </asp:TemplateField>

  in code behind

          private string name;
          private string userId;
          
          protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
          {
              if (e.Row.RowType == DataControlRowType.DataRow)
              {
                  //find the place holder in each row
                  var placeHolder = e.Row.FindControl("hiddenPlaceHolder");
                  HiddenField hfUserId = new HiddenField();
                  hfUserId.Value = userId;
                  Label lblName = new Label();
                  lblName.Text = name;
                  placeHolder.Controls.Add(hfUserId);
                  placeHolder.Controls.Add(lblName);
  
              }
          }

  Hope this helps

  The above code is just for a demostration purpose only, there are several ways you can get the UserName and UserId from sql datasource. What are you trying to do actually??
