How to find the div inside the Gridview (outside of gridview function)

.aspx file

<div id=”tooltip” style=”display: none;”></div>

Code Behind file

Make hide of the div

foreach (GridViewRow row in gvdStatus.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{

HtmlGenericControl dive = new HtmlGenericControl();
dive = ((HtmlGenericControl)(row.FindControl(“tooltip”)));
dive.Visible = false;
}
}

Applying color to the row based on the condition

if (e.Row.RowType == DataControlRowType.DataRow)
{
if (Convert.ToInt32(e.Row.Cells

[2].Text) > 525)
{
e.Row.BackColor = System.Drawing.Color.Blue;
}
}

Note :

A table can have header data or footer rows. The above statement will make sure that the row is data row.
row.RowType == DataControlRowType.DataRow: use it every time if you want to look for something in every row.
