[RESOLVED] Reference dynamic added controls

Hi,

I got a question regarding the *damned* dynamic controls. Just wanted to know if its possible to add some controls on the page init event and use them multiple times (like pointers), i just cant get it to work.

so on page_init

Code:

---

dim l as new linkbutton
l.text = "Test"
l.id = "Test"
l.url = "www.whataver.com"
me.form.controls.add(l)

---

then somewhere else

Code:

---

for i as integer=0 to 5
dim l as new LinkButton
l = me.form.findcontrol("Test")
panel.controls.add(l)
next

---

I just get the control one time and then its no longer in the form controls collection... ANY help would be appreciated

I don't know if you can do it as a Pointer. But you can do it like this.

In Page_Load:

Code:

---

Dim myLnkBtn as LinkButton
For counter as Integer = 0 to 4
    myLnkBtn = New LinkButton()
    myLnkBtn.Id = counter
    myLnkBtn.Text = "Text"
    myLnkBtn.Url = "http://www.google.ca"
    'If you need to add an event to be handled, like Click, this is the place
    'AddHandler myLnkBtn.Click, EventHandler
    Panel.Controls.Add(myLnkBtn)
Next

---

And the handler code:

Code:

---

Private Sub EventHandler (ByVal sender as object, e as eventargs)
    'do something
End Sub

Ok, but my real problem is this, i know i need say 3 linkbuttons, named linkbutton1, linkbutton2 and linkbutton3

In my gridview i want something like this
row linkbutton
1 linkbutton1
2 linkbutton3
3 linkbutton3
4 linkbutton2

So linkbutton3 is used twice, and i want to have the same properties, i tried

dim lb as new LinkButton = Panel.FindControl("2")

But i dont get a new button, i get the button in the Panel...I just want to copy or reference to it..

Plz advice, Figa

Well i hacked my way around this, the problem is to get an eventhandler to work, the controls must be added in the page init or page load. But since my data isnt bound yet, there was no easy way of telling what the buttons properties were going to be.

Well to make a long story short, i added the button with a javascript onclick event like so;
in the GridView_DataBound event loop through each row and add linkbuttons

Code:

---

For Each r As GridViewRow In GridView.Rows
    Dim lb as New LinkButton
    lb.ID = r.Cells(0).Text
    lb.Text = r.Cells(0).Text
    lb.ForeColor = Drawing.Color.Black
    lb.Attributes.Add("onclick", ClientScript.GetPostBackEventReference(GridView, "Proc$" & r.Cells(0).Text))
r.Cells(5).Controls.Add(lb)
Next

---

I changed some stuff, just to keep it simple, now after adding the linkbuttons and the event you can do this.

Code:

---

Protected Sub GridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView.RowCommand
    If e.CommandName = "Proc" Then
            //stuff todo here
    End If       
End Sub

---

It may not be pretty, but it does what i wanted to do.

Anyway thanks for the help, Figa
