[Solved] Trying to understand "PageViewCreated" functionality

[Shawn Currie]

I'm trying to implement a tabstrip with multipage. My page views are dynamically loaded user controls.

This is basically how the flow works.
 
I have a RADgrid (named RadGrid1) that contains a number of columns. When you click on a row in the grid, a tab is created that represents the data of that gridrow. To accompish this I use "RadGrid1_ItemCommand" and check for the "RowClick" command. I then get the name of the column I need and use that to name the tab. Here's the C# code to add the new tab and its coressponding page view.

private

 

void AddTab(string tabName)

 

{

 

    RadTab tab = new RadTab();

 

    tab.Text = tabName;

    RadTabStrip.SelectedIndex = selectedTabIndex;

    RadTabStrip.Tabs.Add(tab);

 

    RadPageView pageView = new RadPageView();

 

    pageView.ID = tabName;

    RadMultiPage.SelectedIndex = selectedTabIndex;

    RadMultiPage.PageViews.Add(pageView);

}

protected

 

void RadMultiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)

 

{

 

    string userControlName = "UserControls/VMDetails.ascx";

 

 

    Control userControl = LoadControl(userControlName, passName, passIP);

 

    userControl.ID = passName +

"_vmdtl";

 

    e.PageView.Controls.Add(userControl);

}

The problem I'm having is that the first two tabs are created fine, but the thrid tab doesn't get created because I get an error on the page indicating the userControl.ID is a dupicate. Trying to debug this issue I noticed that the code doesn't follow the design I think it should follow.

When I click on a row, I would think the first code execution would be in the "RadGrid1_ItemCommand" method to see if the the "RowClick" command is true, however this is not the case. The first execution appears to be the "RadMultiPage_PageViewCreated" method. If you look at the code above, the "passName" value during the execution the third time has a value from the previous tab creation and therefor the userControl.ID is the same.

Why does execution go directly to "RadMultiPage_PageViewCreated'? Any Thoughts?

Thanks!
