loadcontrol

Will the state of a dynamically loaded control preserved in transitions
between aspx pages hosting the control.?
thanks

HrtgSkr, here is the situation. All web pages have header and footers which
are user controls. Iam loading
these controls in base class of my page using LoadControl. Will the state of
these dynamically loaded control
preserved between transitions in pages. For e.g Will the tree control in the
header preserver its state when i
navigate to a different web-pages?

I hope iam clear now.
Appreciate your response.
thanks

You want the parent page to access property values in the usercontrol?

Create public properties in your control, then access them through the
usercontrol on the parent page.

public string ControlName
{
get { return mstrName;}
set { mstrName = value;}
}

protected MyControlClass myControl;

string someName = myControl.Contr olName;

I have found it easier to place the usercontrol on the page, and then
toggle it's visible property depending on the situation.

You probably need to create some events to allow the child to notify
the parent that a value has changed, and the parent to tell the child
to do its' job with that value.

If the parent wants to tell the usercontrol to clear it's properties:

public event EventHandler ClearEvent;

protected virtual void OnClearEvent(Ev entArgs e)
{
if (ClearEvent != null)
ClearEvent(this , e);
}

this.ClearEvent += new
System.EventHan dler(this.myCon trol.OnClearEve nt);

In the usercontrol:

public void OnClearEvent(ob ject sender, System.EventArg s e)
{
mstrName = "";
}

Hope that was what you meant.

The values in the usercontrol properties will not persist. I have
noticed, that the webcontrols inside my usercontrol hold their viewstate
as long as I stay on the parent page. My usercontrol isn't loaded with
loadcontrol, though, so even though it's not visible, it's still "an
instance".

If you're using serialization, you can store the information you need
from the usercontrol in ViewState. There's many ways to preserve the
values. I've just learned through trial and error to start simple, then
build on it, setting breakpoints and using Autos and Watch tabs to see
the state of my variables as I move through the pages.

Do you need to load them dynamically? Can you just modify them to
adjust for each parent page?

Dawn.
