how to get textbox value from a gridview control in a webpage programmed in asp.net 2.0 C#

You are almost nearer. Try this.

TextBox txt=(TextBox)GridViewFRM.Rows[i].Cells[0].FindControl("GVQuestionTextBox");
string Ques = txt.Text;//This will be desired one

Regards..

in button click event.. i tried like below and got the result what i was expecting

string FORID = GridViewFRM.Rows[e.RowIndex].Cells[index].Text;

index is the column number of the gridview

instead of treating it as textbox value, i treated & directly got it as a value from the gridview

thanks guys for all your response

That will not work, you need an instance of the GridViewRow.
From an object oriented perspective, the Gridview has this hierarchy:

GridView fathers GridViewRow fathers Control

So, try:

string Ques = ((TextBox)GridViewFRM.Rows[i].FindControl("GVQuestionTextBox")).Text;

thanks for response guys
will let you know after checking with your answers

thanks

int i=e.NewEditrowindex;

TextBox Ques =(TextBox)GridViewFRM.Rows[i].Cells[0].FindControl("GVQuestionTextBox");
string Ques1 = Ques .Text;//This will be desired one

TextBox txt=(TextBox)GridViewFRM.Rows[i].Cells[0].FindControl("GVQuestionTextBox").Text;
