Developing Pocket PC Applications using Visual Studio.NET 2003 - Working with a datagrid control on Pocket PC using Visual Studio.NET 2003
(Page 5 of 5 )
Life would not be complete without using a “datagrid” control in any .NET application. Now, let us implement a “datagrid” control even with a Pocket PC application.
Follow the steps to achieve the same:
- Delete all the controls you played in the previous section (available on the form).
- Add a new button (called “Fetch”) and a “datagrid” that fits the width of the form.
- Open your code window and copy the following code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click
Dim dr As DataRow
Dim dt As New DataTable
dt.Columns.Add("empno")
dt.Columns.Add("ename")
dt.Columns.Add("sal")
dt.Columns.Add("deptno")
dr = dt.NewRow
dr("empno") = 1001
dr("ename") = "Jag"
dr("sal") = 2500
dr("deptno") = 10
dt.Rows.Add(dr)
dr = dt.NewRow
dr("empno") = 1002
dr("ename") = "Win"
dr("sal") = 3500
dr("deptno") = 10
dt.Rows.Add(dr)
dr = dt.NewRow
dr("empno") = 1003
dr("ename") = "Dhan"
dr("sal") = 5000
dr("deptno") = 20
dt.Rows.Add(dr)
Me.DataGrid1.DataSource = dt
End Sub
- Press F5 to execute your application.
- After a few seconds, once emulator is loaded, press on the “Fetch” button.
- It should give you the output in the following figure (Fig8).
I developed the application using Microsoft Windows Server 2003 Standard Edition with Microsoft Visual Studio.NET 2003 Enterprise Architect and Pocket PC SDK 2003 (along with additional emulators downloaded). The entire solution for this article is freely available in the form of a downloadable zip file.
In my upcoming articles, I shall concentrate further on developing advanced Pocket PC applications. So, keep up with the website!
