Obout Grid：仅在特定行的网格上隐藏图像

Question

使用带有以下列的 obout 网格：

<obg:Column ID="Image" DataField="" HeaderText="" Width="50" runat="server">
   <TemplateSettings TemplateId="ImageTemplate" />
</obg:Column>

以及以下模板：

<Templates>
  <obg:GridTemplate runat="server" ID="ImageTemplate">
    <Template>
      <img src="images/test.png" title="test" />
    </Template>
  </obg:GridTemplate>
</Templates>

我正在尝试以编程方式隐藏某些行上的图像：

protected void grd_RowDataBound(object sender, GridRowEventArgs e)
{
    if (testpassed())
    {
        e.Row.Cells[1].Text = "";  // Column 2 is the image
    }
}

但它并没有隐藏图像。如何仅对某些行使用 obout 网格以编程方式隐藏图像？在此先致谢。

如果找到答案以防将来有人遇到此问题：

protected void grd_RowDataBound(object sender, GridRowEventArgs e)
{
  // Check if this is a DataRow
  if (e.Row.RowType == GridRowType.DataRow)
  {
    // Check if we are hiding the image
    if (testpassed())
    {            
      // Retrieve Image Cell (Column 2 in my case)
      GridDataControlFieldCell cell = e.Row.Cells[1] as GridDataControlFieldCell;

      // Retrieve Literal Control with Image Source Html (Found at Level 5)
      LiteralControl imgTag = cell.Controls[0].Controls[0].Controls[0].Controls[0].Controls[0] as LiteralControl;

      // Remove Html <img src.. code from Literal Control in order to hide image
      imgTag.Text = "";
    }
  }
}
