Adding <tr> from repeater's ItemDataBound Event

My repeater's templates generate a table, where each item is a table row.

When a very very specific condition is met (itemdata), I want to add an additional row to the table from this event.

How c开发者_JS百科an I do that?

protected void rptData_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
   if (e.Item.ItemType == ListItemType.Item ||
         e.Item.ItemType == ListItemType.AlternatingItem)
   {

        bool tmp = bool.Parse(DataBinder.Eval(e.Item.DataItem, "somedata").ToString());
        if (!tmp && e.Item.ItemIndex != 0)
        {
            //Add row after this item
        }

   }
}

I can use e.Item.Controls.Add() and add TableRow but for that I need to locate a table right?

How can I solve that?

I would put in the control in the repeater item template, set its visibility to hidden & only in that case, I will show it...

Like:

<asp:Repeater ...>

..

<ItemTemplate>

 <tr>
   <td>...</td>
 </tr>
 <tr runat="server" id="tr_condition" Visible="false">
  <td> Show only in specific condition </td>
 </tr>

Then in the ItemDataBound event:

var tr_condition = e.Item.FindControl("tr_condition") as HtmlTableRow;
tr_condition.Visible = myCondition;

where myCondition is a flag which gets sets on the specific condition

One way to do this is to include the row in the template code, and set the Visible property based on your 'tmp' variable. The you don't need to 'add' it - it is already there.

Edit: another idea - insert your extra row using a <%# %> data binding block. To do this, you need to generate the <tr><td>.. code as a atring in your ItemDataBound event. Use a protected string variable - like this:

protected string _extraRowHtml;

in ItemDataBound:

_extraRowHtml = tmp ? "<tr><td>  -- generated content -- </td></tr>" : string.Empty;

in ItemTemplate:

<tr><td> -- regular row content --</td></tr>
<%# _extraRowHtml %>
