Hi all,
I have a gridview and I want to take a parameter from it to pass it to an insert function.
I tried this code but I get an exception

string accountname = ((TextBox)GridView2.Rows[j].Cells[0].Controls[0]).Text; 
insert_ReadyMade_Mobil(Int64.Parse(cmb_Subgroupmobiles.SelectedValue.ToString()), Id.ToString());

Can any one help me please, and notice that I fill the gridview in the runtime.
Thanks

First, you're retrieving something you call accountname, but after retrieving it, I don't see where you're using it in the next statement.

Second, I would do this for the 2nd line:

C#

Int64 value;
if (Int64.TryParse(cmb_Subgroupmobiles.SelectedValue.ToString(), out value)
{
    insert_ReadyMade_Mobil(value, ID.ToString());
}
else
{
    // display an error message?
}

Heres a working example from my code:

lblMaxCreditJourneys->Text = gridPassenger->Rows[e->RowIndex]->Cells[this->dgMaxCreditJourneys->Name]->Value->ToString();

Its C++/CLI. Change -> to . and you will have C#

Looks like,it's not able to find out the textbox inside the GridView & throwing exception at your first line itself.To acess textbox inside a Gridview in ASP.net, you need to use FindControl to find the textbox inside and cast it to TextBox.

C#

foreach (GridViewRow row in GridView2.Rows)
    {


     string accountname = ((TextBox)row.FindControl("TextBox1")).Text;

    }

Hope this helps!
