protected void textBox4_TextChanged(object sender, EventArgs e) { // Loop through all rows in the grid foreach (GridViewRow row in grid.Rows) { // Only look for `lbClose` in data rows, ignore header and footer rows, etc. if (row.RowType == DataControlRowType.DataRow) { // Find the `lbClose` LinkButton control in the row LinkButton theLinkButton = (LinkButton)row.FindControl("lbClose"); // Make sure control is not null if(theLinkButton != null) { // Enable the link button theLinkButton.Enabled = true; } } } }
