Dynamically added button's direct event does not work

[mdarco]

Please take a look at this:

protected void Page_Load(object sender, EventArgs e)
{
    Ext.Net.Button b1 = new Ext.Net.Button(); 
    b1.Text = "test button";

    b1.DirectEvents.Click.Event += new ComponentDirectEvent.DirectEventHandler(Click_Event);
    b1.AddTo(pnlCenter);
}

void Click_Event(object sender, DirectEventArgs e)
{
    X.Msg.Alert("test message", "test");
}

The button is dynamically added to the pnlCenter which is on the aspx page.

This produces the following error:

The control with ID 'id1a62f466f3ff47c985aad859f77faac0' not found
Description: An unhandled exception occurred during the execution of

How to dynamically add a control to the page and use its direct event handler?

Darko

EDIT: The code actually works when the button is outside of the panel (directly on the aspx form).
But when the button is put inside the panel the error message appears.
Any ideas how to resolve this?

Hi,

Please replace

b1.AddTo(pnlCenter);

by

pnlCenter.Items.Add(b1);

[mdarco]

Hi,

Please replace

b1.AddTo(pnlCenter);

by

pnlCenter.Items.Add(b1);

Thanks for the quick reply.

The Click_Event now fires but the alert is not displayed!?

Hi,

Need to call 'Show' method

X.Msg.Alert("test message", "test").Show();

Thanks again.

I'm a beginner in Ext.Net so please don't mind the 'stupid' questions. :D:
