Unable to find control inside TemplateDataField
posted

Hello,

with Infragistics v14.2 I am not able to find a servercontrol inside a TemplateDataField. My ASPX-Code looks like this:

<ig:WebDataGrid ID="wdgData" runat="server" EnableViewState="True" EnableDataViewState="True" DataKeyFields="Product" AutoGenerateColumns="false">
  <Columns>
    <ig:BoundDataField Key="Prodduct" DataFieldName="Product" Header-Text="Product"></ig:BoundDataField>
    <ig:TemplateDataField Key="Comment">
      <ItemTemplate>
        <asp:TextBox ID="txtComment" runat="server"></asp:TextBox>
      </ItemTemplate>
    </ig:TemplateDataField>

  </Columns>
</ig:WebDataGrid>

The grid is filled on PageLoad and shows the data as expected. However when I click an ASP.NET - Button my code is not able to get the TextBox. The code looks like this:

void btnButton_Click(object sender, EventArgs e)
{
  foreach (Infragistics.Web.UI.GridControls.GridRecord r in wdgData.Rows)
  {
    TextBox textbox = (TextBox)r.Items[0].FindControl("txtValue");

    if (textbox != null) // -> always null
    {
        //Do something with the textboxvalue
    }

  }
}

The project is configured to use .NET 4.5. If I set up a project using .NET 3.5 and Infragistics v12.2 my code is running fine and working as expected. Is there anything that has changed from v12.2 to v14.2?
