Hello

I added columns dynamically to gridview at run time and have added textboxs to every column using row data bound.

but now when i try to get this value in another button click i get null reference error.

I know that as pageload do not retains values ,i am not getting the required result.but what is solution on it?

here is my code..

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)
{

for (int i = 0; i < 6; i++)
{
TextBox txt = new TextBox();
txt.CssClass = "SmallTextBoxDate";
txt.ID = "TextBox" + (i).ToString();
if (dt != null && dt.Rows.Count > 0)
{
{
txt.Text = dt.Rows[e.Row.RowIndex][i - 1].ToString();
}
}
e.Row.Cells[i].Text = "";
e.Row.Cells[i].Controls.Add(txt);
}

}
}
}
protected void btnAdd_Click(object sender, EventArgs e)
{

string A=(((TextBox)gvrItem.FindControl("txtE")).Text).tostring();//Here I m getting null value
}
