TextBox1 is in your ItemTemplate, You need to find the TextBox to get it’’s value.
Replace your loop with this:
foreach (GridViewRow GVRow in GridView1.Rows)
{
Member_ID = GVRow.Cells[0].Text;
TextBox1 = ((TextBox)GVRow.FindControl(\"TextBox1\")).Text;
SqlConnection myConnection = new SqlConnection(\"user id=sa;\" +
\"password=prodip@km;server=PRODIP;\" +
\"Trusted_Connection=yes;\" +
\"database=Member;\");
myConnection.Open();
SqlCommand myCommand = new SqlCommand(\"INSERT INTO [Collectionamt ] (Member_ID,collectionamt,collectiondate)\" +
\"Values(@Member_ID,@TextBox1,GETDATE())\");
myCommand.Parameters.Add(\"@Member_ID\", System.Data.SqlDbType.Int).Value = Convert.ToInt32(Member_ID);
myCommand.Parameters.Add(\"@TextBox1\", System.Data.SqlDbType.VarChar,50).Value = (TextBox1.ToString());
myCommand.Connection = myConnection;
myCommand.ExecuteNonQuery();
Response.Write(\"<script language=\"'javascript'\">{alert('\" + \"Data is Save')}</script>\");
myConnection.Close();
}
