Make Rows in DataTable to InVisible

Hi  

please help,

Want to make the rows in the DataTable to invisible, for the below situation(Web Application)

I'm googled but not find the exact result.

if (itemstodisablelist.Count() != 0)
{
for (int i = 0; i < itemstodisablelist.Count(); i++)
{
rowCount = 1;

foreach (DataRow grd1Row in dt.Rows)
{
if (valueKeys[i].Equals(dt.Rows[rowCount][1].ToString()))
{

dt.Rows[rowCount].Visible = false;    //  Have to make the Row in the DataTable To Invisible.. Visible Property is not working here . What will be the exact replacement for this
grd1Row.Visible = false;

}

rowCount++;
}
}
}

Thanks in Advance :-)

Best regards
