dynamic generation of input control

Hello Fung,

Thank you for your suggestion. However, this is not recommended because all binding code should be placed in InitializeDataSource event.
Regarding this issue, I would like to re-confirm that this is not a bug. Please see below sample to see how should we handle this scenario.

Regards,
Hamdy

Hi All,

I had also come across with the problem recently, and I had add some code to 'work around' this problem.

Private Sub Page_Load()
  LoadGrid()
End Sub
Private Sub LoadGrid()
  dim dataTable1 as DataTable=GetYourData()
  webgrid1.DataValueField="Value"
  webgrid1.DataTextField="Text"
  webgrid1.DataSource=dataTable1
  webgrid1.DataBind()
  RemoveHandler webcombo1.InitializeDataSource, AddressOf WebCombo1_InitializeDataSource
   AddHandler webcombo1.InitializeDataSource, AddressOf WebCombo1_InitializeDataSource
End Sub
Private Sub WebCombo1_InitializeDataSource(ByVal sender As Object, ByVal e As ISNet.WebUI.WebCombo.DataSourceEventArgs) Handles WebCombo1.InitializeDataSource
End Sub

Hello Ca,

Yes, my sample only showed you how to add WebCombo without bind it with database.
If you want it with database value, you need to bind it with database. Add InitializeDataSource event handler when create WebCombo programmatically and bind the data in that event.

Hi Ca,

I attached my simple sample. I made a quick selection option in DropDownList control. In some certain values, I add WebCombo or WebInput. Hope this helps.
