Question

I am trying to use a label from another row in the gridview and insert it in a table when the user clicks the button which is in its own column.

my problem is that i cant get bookno which finds the label set to the @bookno in my sqldatasource

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim selectedRow As Button = DirectCast(sender, Button)



        Dim bookno As Label = CType(selectedRow.FindControl("label1"), Label)
        Dim why As TextBox = CType(selectedRow.FindControl("textbox2"), TextBox)
        Dim yesint As Integer = 1
        Dim sql As SqlDataSource = CType(selectedRow.FindControl("sqldatasource4"), SqlDataSource)
        sql.InsertParameters.Add(bookno.Text, 0)


        sql.Insert()

    End Sub

Answer 1

Try

Dim bookno As Label = CType(selectedRow.Parent.FindControl("label1"), Label)

and see if you get a valid control for bookno. If it works, do the same for other FindControl() calls.
