Hi yalamanchir,

What do you mean exactly by "change the number of rows" ?

Is it paging problem ?
If so, modify the datagrid page size with the user value and (re)bind datas.

Or a data problem ?
Then , when you (re)bind datas, modify the filter of your dataview considering the user value.

Hope this will help you.
Regards.

You set the datasource to a table perhaps, right?

then you should add rows the the underlying datatable, and that will "add" rows to the datagrid.

public function addrows(numrows as integer)

        Dim table As DataTable = CType(DataGrid1.DataSource, DataTable)
        For i As Integer = 1 To numrows
            Dim row As DataRow = table.NewRow
            table.Rows.Add(row)
        Next i
    End Sub

You can not change the Number of Rows in the DataGrid directly.
The Datagrid shows the number of rows based on the underlying dataTable
So in case you want to modify the Number of Rows you'll have to modify the Number of rows in the Underlying Table

You will need to update your sql to pull just the number of records you want ie
"SELECT TOP " & CInt(TextEntry.Text) & " * FROM tblCustomer WHERE ......... "
Dont forget to rebind your datagrid to update the changes
