Solution 1

you can iterate through the grid using grid.Rows
like

foreach(GridViewRow row in grid.Rows)
{
Control cntrl = row.FindControls("controlName");

}

if you have a Label then you can casta to Label and use the property from it.

Label lblControlName = row.FindControl("controlName") as Label;

the above case will work with Itemtemplate if you are using bound column you can use row.Cells[] array and find the value.

hope it helps..

//Take a textbox(txtSearch) and A button(Search) on your Page
//Follow this Code .....
private void SearchText()
{
/////////////Bind Your Grid Here
bindGrid();
string SrchExpression = null;
if (!String.IsNullOrEmpty(txtSearch.Text))
{
SrchExpression = string.Format("{0} '%{1}%'",
GridName.SortExpression, txtSearch.Text);

}
dv.RowFilter = "CustomerName Like" + SearchExpression;
GridName.DataSource = dv;
GridName.DataBind();

}

//To find Your Expression
public string Highlight(string InputTxt)
{
string Search_Str = txtSearch.Text.ToString();
Regex RegExp = new Regex(Search_Str.Replace(" ", "|").Trim(),
RegexOptions.IgnoreCase);
return RegExp.Replace(InputTxt,
new MatchEvaluator(Words));
}

public string Words(Match m)
{

return "<span class=highlight>" + m.Value + "</span>";
