Hi Kavithale

if you are using template field in the gridview:
foreach (GridViewRow gr in yourGrid.Rows)
{
string strValue = ((Label)gr.FindControl("controlname")).Text
}

or

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
DataGridViewRow row = dataGridView1.Rows[i];
row.Cells[2].Value = true;
}

DataGridViewRow IS THIS MY GRIDVIEWNAME?

Orcun Iyigun 5-Mar-13 5:04am

yourGrid!!!! is the ID of your gridview...(in the for each loop)
dataGridView1 is the ID of your gridview...(in the for loop)

No Kavithale... It is a DataGridViewRow Class (System.Windows.Forms)

you have to replace dataGridView1 with your gidview name
