Hi All,

I don't want to show any row in highlighted mode.
by default it should be in highlight mode for the top row of Datagridview.

i tried Datagridview1.ClearSelection();
but still the top row is displayed in highlighted mode.

here is my code

<pre><pre lang="C++">private void FillGridView()
{
try
{
DataTable dtfillgrid = new DataTable();
dtfillgrid = dc.GetDataTable(&quot;Select * From SIF Where UID=&quot; + Convert.ToInt32(Constants.NodetooltipUnit));
DataTable dtClassificationSIFIDs = new DataTable();
dtClassificationSIFIDs = dc.GetDataTable(&quot;Select SIFID from ClassificationSIF&quot;);
if (dtfillgrid.Rows.Count &gt; 0)
{
dgrid.DataSource = dtfillgrid;
dgrid.Columns[&quot;SIFID&quot;].Visible = false;
dgrid.Columns[&quot;UID&quot;].Visible = false;
//dgrid.ClearSelection();
//dgrid.Rows[0].Selected = false;
if (dtClassificationSIFIDs.Rows.Count &gt; 0)
{
for (int i = 0; i &lt; dtClassificationSIFIDs.Rows.Count; i++)
{
for (int j = 0; j &lt; dgrid.Rows.Count; j++)
{
if (dtClassificationSIFIDs.Rows[i][&quot;SIFID&quot;].ToString().Equals(dgrid.Rows[j].Cells[&quot;SIFID&quot;].Value.ToString()))
{
dgrid.Rows[j].DefaultCellStyle.BackColor = Color.Green;
}
}
}
}
}
}
catch (Exception ex)
{
DataClass.LogError(ex);
}
}</pre></pre>

let me know if u have any idea.

Regards,
Pawan.
