Hi Bob,
I would suggest writing a new render method for your gridview items instead
of using a HTML table.
We had done something similar in ASP.Net 1.1 using a datagrid.
the code we used was something like this:
//first set a new render method
private void dgRoI_ItemCreated(object sender, DataGridItemEventArgs e)
{
if(ListItemType.Item == e.Item.ItemType ||
ListItemType.AlternatingItem == e.Item.ItemType)
{
e.Item.SetRenderMethodDelegate(new
System.Web.UI.RenderMethod(NewRenderMethod_Div));
}
}
//This is the new render method that we are going to use. In this we use a
class level variable to intRowCounter to keep track of the number of rows we
have render. Only for the first row, (when no rows have been rendered as
yet) create the div and the table.
private void NewRenderMethod_Div(System.Web.UI.HtmlTextWriter writer,
System.Web.UI.Control ctl)
{
if(intRowCounter==0)
{
writer.Write("<TD colspan=\"11\">");
writer.Write("<DIV id=\"CombinedDiv\" style=\"OVERFLOW:
auto; overflow-y:scroll; HEIGHT: 250px\">\n");
writer.Write("<TABLE id=\"DivTbl1\" border=\"1\"
style=\"border-collapse:collapse;\" bordercolor=\"Black\" cellpadding=\"0\"
cellspacing=\"0\" align=\"left\" >");
writer.Write("<TR align=\"Center\"
style=\"height:30px;\">");//align="Center" style="height:30px;"
}
for(int i=0; i<= ctl.Controls.Count-2; i++)
{
ctl.Controls[i].RenderControl(writer);
}
intRowCounter+=1;
}
This will render the datagrid in the format you want. Hope you can adapt
this for ASP.Net2.0 gridview.
regards,
Animesh
