Question

In my PrinterPackage.aspx file i have the following ‘User Control’:

<%@ Register Src="~/ProvisionControls/DeferredTaxRollforwardControl.ascx" TagPrefix="uc9" TagName="DeferredTaxesRollforwardControl" %> 
   ...
   ...
 <div>
    <uc9:DeferredTaxesRollforwardControl ID="DeferredTaxesRollforwardControl1" runat="server" />
 </div>

which calls the control file ‘DeferredTaxRollforwardControl.ascx‘ that contains my table defined as follows:

<table style="width: 4600px; border-spacing:0px;" border="0" frame="hsides" cellpadding="2" cellspacing="1">

<tr id = "tblTempDiff"> //want to import this


<td style="width:7.6%;" width="2px;" class="paintYellowTotalLeftBold">
    Grand Total Current
</td>
<td style="width:2.8%;" width="2px;" class="paintYellowTotalBold">
    <asp:Label ID="lblGrandTotalUnadjustedBeginningBalance" runat="server" Text=""></asp:Label>
</td>
... and more <td>

I am trying to display the table and also hide some of the columns using the following code in my PrinterPackage.aspx.cs file :

 TableRow row = DeferredTaxesRollforwardControl1.FindControl("tblTempDiff") as TableRow;
        row.Cells[0].Visible = true;
        row.Cells[1].Visible = true;
        row.Cells[2].Visible = true;
        row.Cells[3].Visible = true;
        row.Cells[4].Visible = true;
        row.Cells[5].Visible = true;
        row.Cells[6].Visible = true;
        row.Cells[7].Visible = true;
        row.Cells[8].Visible = true;
        row.Cells[9].Visible = false;
        row.Cells[10].Visible = false;
        row.Cells[11].Visible = false;
        row.Cells[12].Visible = false;

But, this doesn’t seem to pick up the table row tblTempDiff and gives me a null value instead. How can i import the data from the TableRow tblTempDiff into row and then hide whatever columns i want to hide?

Please ask me questions if you need more information, as i know i am not the best person when it comes to explaining my questions.

Answer 1

The code behind cannot see the <tr> you created because it’s not a server control. Add the runat="server" attribute to the <tr>:

<tr id="tblTempDiff" runat="server">

And use System.Web.UI.HtmlControls.HtmlTableRow instead of TableRow. Two different things.
