WebFlyPostBackManager is tightly integrated with other Intersoft controls.

This topic will show you how to use WebFlyPostBack with Intersoft controls.

To use WebFlyPostBackManager with Intersoft Control

1. Add a new page in your project and named it as UsingWebFlyPostBackManagerWithIntersoftControl.aspx.
2. Drag WebFlyPostBackManager, WebCombo and WebGrid controls into the WebForm.
3. Right-click on WebCombo control and choose WebCombo.NET Designer.
4. Go to Columns and Rows section and create a new column.
   
   
   
   
5. Go to Rows tab, add Customers as a new row and click OK.
   
   
   
   
6. Go to Advanced Settings and set AllowAutoPostback to True.
7. Bind and customize WebGrid using code-behind like following:

   C#

   Copy Code

   protected void WebGrid1_InitializeDataSource(object sender, ISNet.WebUI.WebGrid.DataSourceEventArgs e) { if (WebCombo1.Text == "Customers") { dsNorthwind.CustomersDataTable dt = new dsNorthwind.CustomersDataTable(); dsNorthwindTableAdapters.CustomersTableAdapter da = new dsNorthwindTableAdapters.CustomersTableAdapter(); da.Fill(dt); e.DataSource = dt; } } protected void WebGrid1_PrepareDataBinding(object sender, ISNet.WebUI.WebGrid.DataSourceEventArgs e) { if (WebCombo1.Text == "Customers") { WebGrid1.RootTable.DataKeyField = "CustomerID"; WebGrid1.RetrieveStructure(); } }

   
   
8. Call RebindDataSource() using ValueChanged WebCombo server-side event.
   

   C#	Copy Code
   protected void WebCombo1_ValueChanged(object sender, ISNet.WebUI.WebCombo.ValueChangedEventArgs e) { WebGrid1.ClearCachedDataSource(); WebGrid1.RequiresUIRefresh = true; WebGrid1.RebindDataSource(); }

   
   
9. Now, create a page with WebFlyPostBackManager control included in it.
10. Right-click on WebFlyPostBackManager control and choose Properties.
11. Set EnableUIMode to True and locate ServiceURL into UsingWebFlyPostBackManagerWithIntersoftControl.aspx.
12. Expand FlyPostBackSettings and set the following properties.
    

    Property	Value
    PostControlState	True
    PostHiddenFields	True
    PostInputControls	True
    PostViewState	True

    
    
13. Add ISNet.WebUI.WebDesktop as reference and configure WebFlyPostbackManager at server side.
    

    C#	Copy Code
    using ISNet.WebUI.WebDesktop; WebFlyPostBackListener listener = null; protected void Page_Load(object sender, EventArgs e) { listener = new WebFlyPostBackListener(this); }

    
    
14. Run the project.
