Can any one help me to do the following scenario:
On page load: Read product group from database and add dynamic button for each group into Doc1(Doc1 already exist in form) - running well.
When I click any of these Doc1.product group button their event handler creates new button with event handler for each product in database related to that group and add them to Doc2. - running well.
My problem is when I click any of the Doc2.product button and after the page is post back the Doc2 return empty and the event handler does not fire.
I appreciate if any one tell me how to keep these Doc2.product buttons exist until I click different Doc1.group button then I clear the Doc2 combonents (buttons) and add new buttons with event handler related to the clicked group.
Best Regads,
MFE

I believe that the dynamically created Button is not recreated and that is the reason for this behavior. If you add dynamically controls to RadDock you should recreate them on each postback(ajax call), otherwise they will disappear.
If you think that the problem is different, please open a new support thread and send us a running project where we could observe the problem. Once we receive it we will do our best to help you.

protected
override void OnInit(EventArgs e)
{
base.OnInit(e);
BuildUI bu = new BuildUI(this.Form);
}
public
class BuildUI
{
private HtmlForm m_HtmlForm;
public HtmlForm HtmlForm
{
get { return m_HtmlForm; }
set { m_HtmlForm = value; }
}
public BuildUI(HtmlForm hf)
{
m_HtmlForm = hf;
Button btn = new Button();
Panel p = (Panel)m_HtmlForm.FindControl("maincontent").FindControl("pnlBottom");
p.Controls.Add(btn);
}
}
Set the properties of your controls, somewhere in the Page_Load event of your page:
protected void Page_Load(object sender, EventArgs e)
{
BuildUiProperties bup = new BuildUiProperties();
bup.SetProperties(this.pnlBottom
);
}
public class BuildUiProperties
{
Public BuildUiProperties()
{
}
public void SetProperties(Control parent)
{
foreach (Control c in parent.Controls)
{
if
(c.ID == null && c.GetType().ToString().Equals("System.Web.UI.WebControls.Button"))
{
((Button)c).Click += new EventHandler(BuildUiProperties_Click);
((
Button)c).Text = "Add New Users";
}
}
public void BuildUiProperties_Click(object sender, EventArgs e)
{
//Do stuff
}
}
Doing it this way, will cause the button click event to be fired when clicked.
