Dynamic Checkboxes? Or a different way all together

[ryushinyama]

New to asp.net. Pretty familiar with vb.net. This maybe a simple question but I can't seem to find a good answer to it anywhere or at least an alternative/better way.

I am trying to dynamically create checkboxes for items that need to be selected and updated in the database.

The code below will allow those checkboxes to be created and display on the web form and work correctly. However, when I try to access them from another function/Sub I can not.

 
Private Sub GetData( orderNumber as integer)
 
        sqlQueryString = "exec OrderItems " & orderNumber
 
        Dim objDs As DataSet
        Dim objSQLDa As SqlDataAdapter
        Dim objRow As DataRow
 
        objDs = New DataSet()
 
        objSQLDa = New SqlDataAdapter(sqlQueryString, ConnString)
 
        objSQLDa.Fill(objDs, "Dropship Data")
 
 
        Dim chk(objDs.Tables(0).Rows.Count) As CheckBox
        i = 0
 
        For Each objRow In objDs.Tables(0).Rows
 
            sItemID = "<strong>ItemID:</strong> " & objRow("ItemID").ToString & "<br>" & CrLf
            sBrand = "<strong>Brand:</strong> " & objRow("Brand").ToString & "<br>" & CrLf
            sDropShip = "<strong>Dropship:</strong> " & objRow("dropship").ToString & "<br>" & CrLf
 
            chk(i) = New CheckBox
 
            chk(i).ID = objRow("id").ToString
            chk(i).Text = sItemID & sBrand & sDropShip
 
            Me.productData.Controls.Add(chk(i))
            i += i
        Next
End Sub
 

Now I can't get the data back after submitting the form. It is really easy to work with the controls that are created in the design view. But I don't know how to work with the controls created in the code.

I would like to check the boxes that are needed. Click a submit button. Then have the click button event handler loop through the ID's for the checked boxes and process a stored proc that will do all the updates in the DB that need to be done.

Something like:

 
Sub DoThisWhenTheButtonIsPressed()
 
   For i=0 to uBound(chk)
        if chk(i).checked then
            DoStoredProc(chk(i).ID)
        end if
   Next
 
End Sub
 
 

It is really easy to work with controls that are created in the design view. I just can't find out how to get the data from the controls that are created in the code.

Also is there a method for view all the post back data from the form? Something like:

response.write me.form1.postbackdata


Thanks for your help!

Its like someone back in 2004 was thinking, "Hey, this guy is gonna come looking for this later. I'd better get it up now."

Exactly what I was looking for, thanks!!

The code posted in the article that you've been linked to will probably work for now but you could possibly run into problems in the future because you are instantiating the control in your Page Load event. You should instead move this code to your Page Init event. The reason is outlined in this article about how to use dynamic controls in ASP.NET
