Accessing Child Controls

[Jonathan Williams]

Hi,
I have an object which inherits from WebControl (CUSTOM : WebControl)

In this object I have code in which I add child contols:
protected override void CreateChildCont rols()
{
//this.Controls.C lear();
CustomFieldUtil objCustomFieldU til = new CustomFieldUtil ();
DataTable objDT = objCustomFieldU til.GetDataTabl e("custom");
for(intCount = 0; intCount < objDT.Rows.Coun t; intCount++)
{
if (objDT.Rows[intCount]["Name"].ToString().Tri m() != "")
{
LBL myLbl = new LBL();
myLbl.ID = "Label" + intCount.ToStri ng();
myLbl.Text = objDT.Rows[intCount]["Name"].ToString();
this.Controls.A dd(new LiteralControl( "<tr><td class=\"regLabe lCell\"
width=\"20%\">" ));
this.Controls.A dd(myLbl);
this.Controls.A dd(new LiteralControl( "</td>"));
}
....etc.
}
I'm having problems accessing those controls that I add there from another
function. When I do the following code intCount returns 0!

foreach (Control ctrl in this.Controls)
{
this.intCount++ ;
}

AHHH! what happend to the reference?

Thanks

Sometimes kids are like that. Especially if you were too liberal in raising
them.

Actually I didn't define the structrue of the LBL's etc. I'm generating
based on someone else class.

You'll notice that those labels I add through create child controls are
inherit from controls themselves. LBL myLbl = new LBL(); LBL inherits from Label

so myLbl has a couple properties and methods

Ok, here's what I'm trying to do and having trouble with.
From within CUSTOM : WebControl, INamingContaine r

I want to create another function like editable in which I would access
those dynamically created LBL's and mess with thier properties
(functionality to make it editable or not is already encapulated, I just
need to set a bool to true or false)

Whey I try to access these it seems they are Literal controls or somthing.

Thanks for the help, if you can even understand me :)

I'm not clear where your for loop is exactly.
Is this happening outside of the control?
If so, you should try changing your code to this:

foreach (Control ctrl in myCustomControl .Controls)
{
this.intCount++ ;
}

Should I be adding each of those LBL's I create into an array or collection
for future access?

That sounds like a good thing to try.

This whole thread is me talking to myself LOL ;-)

So what I did was renamed the protected override void CreateChildCont rols()
to private void myCreateChildCo ntrols() and everything started working like
I wanted it to. That is the method calls to the LBL's etc.

I guess I just don't understand the purpose of the protected override void
CreateChildCont rols() and was using it incorrectly.
