public partial class Repair_Information_mapping_Home : System.Web.UI.Page
{
public SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["WebConStr"].ToString());
protected void Page_Load(object sender, EventArgs e)
{
load_Grid1();
load_Model();
}
private void load_Grid1()
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter("select Site_Name from Master_Site_Details order by Site_Name", con);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
con.Close();
}


private void load_Model()
{
int i = 0;
foreach (GridViewRow gvr in GridView1.Rows)
{

string s = gvr.Cells[0].Text.ToString();
SqlCommand cmd = new SqlCommand("select VDI_Model,count(VDI_Model) as No from Vehicle_Details_Information where Site_Locn='" + s + "' group by VDI_Model", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
//If ds.Tables.Count>0 then
if (ds.Tables[0].Rows.Count > 0)
{

GridView gvwnested = (GridView)GridView1.Rows[i].FindControl("GridView2");
gvwnested.DataSource = ds.Tables[0];
gvwnested.DataBind();

}
else
{
gvr.Cells[1].Text = "No Assets Present";
gvr.BackColor = System.Drawing.Color.DarkGray;
}
ds.Clear();
i = i + 1;
}


}
protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e)
{

GridViewRow row = GridView1.Rows[0];
GridView gvwnested = (GridView)row.FindControl("GridView2");
//int index = GridView1.EditIndex;
//GridViewRow row = GridView1.Rows[index];
//GridView gvwnested = (GridView)row.FindControl("GridView2");
//GridView gvwnested = (GridView)GridView1.Rows[e.RowIndex].Cells[1].FindControl("GridView2");
string model = gvwnested.Rows[e.RowIndex].Cells[0].Text.ToString();
string site = GridView1.Rows[e.RowIndex].Cells[0].Text.ToString();
Response.Redirect("Webform2.aspx?Site=" + site + "Model=" + model);

Nope dear...
ERROR:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

No..
it's:-
Object reference not set to an instance of an object.

In Gridview2_Row_Updating event:
GridView gvwnested = (GridView)GridView1.Rows[0].Cells[1].FindControl("GridView2");
string model = gvwnested.Rows[e.RowIndex].Cells[0].Text.ToString();
string site = GridView1.Rows[e.RowIndex].Cells[0].Text.ToString();
Response.Redirect("Webform2.aspx?Site=" + site + "Model=" + model);

Error is coming at the 2nd line when i assign a value of child gridview to 'model'

Nope...
Its not working...

I have placed child gridview in the 2nd column of every row of parent gridview.i.e. cell[1] of parent gridview.

Plz give the code of gridview2_rowupdating() event...
I want to access the row of childgridview using childgridview _rowupdating() event...
