Hi experts..

I have a template that I load that is comprised of a simple html table structure..

structure is similar to below..

<table id="MainForm">
   <tr>
      <th>
         Column1
      </th>
      <th>
         Column2
      </th>
      <th>
         Column3
      </th>
   </tr>
   .
   .
   .
</table>

In the dotted section I want to prgramatically insert <tr> and <td> elements..

Reason is that I am building an email template on the fly that will contain a variable number of rows retrieved from a database..

The table structure is fairly basic and static (column headings etc..), but the nbumber of rows returns will be varialble..

Can someone help in pointing me to the right way to achieve this please?

Thanks in advance..

set the runat=server property to table tag like this and id

<table id="MainForm" runat= "server">

then in code behind

 //Instantiate Row Object and Cell Object

       

        HtmlTableRow htRow = new HtmlTableRow();

        HtmlTableCell htCell = new HtmlTableCell();        

 

        //Add Text to cell and add Cell to Row

 

        htCell.InnerText = "This is Implementation of HTML Control";

        htRow.Cells.Add(htCell);

        MainForm.Rows.Add(htRow);

 

        //Add Second Row in a Table

       

        htRow = new HtmlTableRow();

        htCell = new HtmlTableCell();

 

        TextBox txttext = new TextBox();

        txttext.Visible = true;

        txttext.Text = "Inside Cell";

       

        htCell.Controls.Add(txttext);

        htRow.Cells.Add(htCell);

        MainForm.Rows.Add(htRow);

You have to create a  a Label Control or PlaceHolder Control in your HTML

string htmlTable = "<table><tr><td>" + yourData + </td></tr></table>;

YourLabel.Text = htmlTable;

Hi
Just look this code
protected void Page_Load(object sender, EventArgs e)
{
 
        //Instantiate Row Object and Cell Object
       
        HtmlTableRow htRow = new HtmlTableRow();
        HtmlTableCell htCell = new HtmlTableCell();      
 
        //Set the sytle of a table
       
        table1.BgColor = "#FCDDFE";
        table1.Align = "left";
        table1.Border = 1;
        table1.Attributes["Style"] = "font-family:Verdana;font-size:11px;font-style:italic;";
 
        //Add Text to cell and add Cell to Row
 
        htCell.InnerText = "This is Implementation of HTML Control";
        htRow.Cells.Add(htCell);
        table1.Rows.Add(htRow);
 
        //Add Second Row in a Table
       
        htRow = new HtmlTableRow();
        htCell = new HtmlTableCell();
 
        TextBox txttext = new TextBox();
        txttext.Visible = true;
        txttext.Text = "Inside Cell";
       
        htCell.Controls.Add(txttext);
        htRow.Cells.Add(htCell);
        table1.Rows.Add(htRow);
 
}

One way this could be done is that you store the header only in the template like below

<table id="MainForm">
   <tr>
      <th>
         Column1
      </th>
      <th>
         Column2
      </th>
      <th>
         Column3
      </th>
   </tr>


Note the missing </table> tag. Now you can just append text to the template and then at the end, append the </table></body></html> nodes when finished.



If there is more than </table></body></html> at the end, you can store it in a separate file and append that file at the end.

Hi all..
Thanx for the responses..
To be honest, all solutions presented would have worked, so I split the points equally..
I ended up using a solution that used placeholdes in a standard HTML form, then replacing these placeholders with valid HTML in code behind, that I built on the fly after pulling the data from the DB..(Just like PHP)
Once again, thanx for the solutions..All very helpful.
