Hi,

I dont know it is doable, but I wanna ask it anyway.

I am pulling 5 different data from a datatable row by row. So each row
has 5 fields and row count is variable not a constant. So, each row's fields
will be shown in a table in a different design. That means, I cannot use
DataGrid, because the view should be different. Here is the html:table
structure fo each datarow:

<table>
for (int i=0;i<DataSet.Tables["mytable"].Rows.Count;i++)
{
DataRow row = DataSet.Tables["myTable"].Rows;
// from here the html table's rows are being entered
<tr>
<td width=18%><img src=row[4].ToString()></td>
<td colspan=2>row[2].ToString()</td>
</tr>
<tr>
<td rowspan=2>&nbsp;</td>
<td rowspan=2 width=54%>row[5].ToString()</td>
<td width=28%>row[3].ToString()</td>
</tr>
<tr>
<td>row[1].ToString</td>
</tr>
<tr>
<td colspan=3><a href=details.aspx?dno=row[0].ToString()>Click Here
For More Info</a></td>
</tr>
}
</table>

As you have seen here, the table row count cannot be known, so I will
have to create tablerows as much as the datarow goes.

I have tried to do it with Rersponse.Write, but it is writing all of
these on top of the page, and it is ruining the design. I have tried to use
the <asp:Table> object, but it needs the <asp:TableRow> and <asp:TableCell>s
to be declared at design time. I wanted to do it inline of the aspx page, it
has given alot of runtime errors regarding to the compilation. (Because I am
using VS.NET and I am writing the code behind, not in the aspx files.)

So, how can I create these table rows on-the-fly ? Or I am kind of hoping
that, there must be another command, that does similar thing Response.Write
command does, but it puts the code whereever I want to be put.

Thanks and Regards.

Create your table w/ the LiteralControl. The LiteralControl takes as it's
constructor a string argument...which is the html. Build that string with a
StringBuilder object.
Put a PlaceHolder control on the aspx page and add a the new LiteralControl
to the PlaceHolder control. Something like this:

private void MakeTable(DataTable dt)
{
StringBuilder mytable = new StringBuilder("<table width=/"100%/">");
for each ( DataRow dr in dt )
{
mytable.Append(GetRow(dr));
}
mytable.Append("</table>");
myPlaceHolder.Controls.Add(new LiteralControl(myTable.ToString()));
}

private string GetRow(DataRow dr)
{
//do the processing on the row
}

PJ,

Thank you very much. It is exactly what I was looking for.
