How to Load on Demand RadPageView

[Jorge Cardenas]

Hi All, I am following the Load on Demand RadPageView example and everything is working correctly except for the fact that I am trying to load PageIndex  2 and show PageIndex 2. When I do this the tab shows up blank as if nothing was loaded. I believe the actual tab is loading but at index 0, any guidance or a how to will be much appreciated.

Thanks

protected void Page_Load(object sender, EventArgs e)

 

{

 

 

if (!Page.IsPostBack)

 

{

AddTab(

 

"General Information");

 

AddTab(

 

"Change Password");

 

AddTab(

 

"Quick Links");

 

AddTab(

 

"Application Access");

 

 

 

int i = -1;

 

 

 

if (Request.QueryString["PageIndex"] != null)

 

 

 

Int32.TryParse(Request.QueryString["PageIndex"], out i);

 

 

 

switch (i)

 

{

 

 

case 2:

 

RadMultiProfile.SelectedIndex = 2;

RadTabProfile.SelectedIndex = 2;

AddPageView(RadTabProfile.FindTabByText(

 

"Quick Links"));

 

　

 

 

break;

 

 

 

default:

 

AddPageView(RadTabProfile.FindTabByText(

 

"General Information"));

 

 

 

break;

 

}

　

}

}

 

 

private void AddTab(string tabName)

 

{

 

 

RadTab tab = new RadTab();

 

tab.Text = tabName;

RadTabProfile.Tabs.Add(tab);

}

 

 

private void AddPageView(RadTab tab)

 

{

 

 

RadPageView pageView = new RadPageView();

 

pageView.ID = tab.Text;

RadMultiProfile.PageViews.Add(pageView);

tab.PageViewID = pageView.ID;

}

 

 

protected void RadTabProfile_TabClick(object sender, RadTabStripEventArgs e)

 

{

AddPageView(e.Tab);

e.Tab.PageView.Selected =

 

true;

 

}

 

 

protected void RadMultiProfile_PageViewCreated(object sender, RadMultiPageEventArgs e)

 

{

 

 

string userControlName = "Controls/" + e.PageView.ID.Replace(" ", "") + ".ascx";

 

 

 

Control userControl = Page.LoadControl(userControlName);

 

userControl.ID = e.PageView.ID +

 

"_userControl";

 

e.PageView.Controls.Add(userControl);

}

Hello Jorge,

With the Load on Demand RadPageView demo, you need to modify the code as follows to achieve this requirement:

protected void Page_Load(object sender, System.EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                AddTab("Customers");
                AddTab("Products");
                AddPageView(RadTabStrip1.FindTabByText("Products"));
                AddTab("Orders");
                RadTabStrip1.SelectedIndex = 1;
                RadMultiPage1.SelectedIndex = 0;
           }
        }

Note that SelectedIndex of RadMultiPage has to be set to 0, because when AddPageView() is executed and the PageView is added, its index automatically becomes 0.

private void AddPageView(RadTab tab)
        {
            RadPageView pageView = new RadPageView();
            pageView.ID = tab.Text;
            RadMultiPage1.PageViews.Add(pageView);
            pageView.CssClass = "pageView";
            tab.PageViewID = pageView.ID;
        }

Thanks Peter it worked! But I have another problem.

Within that same page I have required field validator and the application throws a random javascript error (Expected ';'). As soon as I take out all the validators the page is fine with no javascript errors. Please help.


--Update:  Actually none of the client side validation works in IE or Firefox.


Thanks.

Hi Jorge,

I tried to reproduce the error by placing a RequiredFieldValidator control in the aspx page of the demo, but to no avail. Everything worked smoothly on my end.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
  <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1"
      ErrorMessage="RequiredFieldValidator">

How exactly do you use validators in  your page?


Kind regards,

Hi Peter I have attached the error that I am getting and have submitted a ticket with a code sample that creates the problem on my side  under IE and Firefox. Please see the following ticket ID : 303480 for the sample app.

Thanks.

Hello Jorge,

We replied to your ticket. The problem still cannot be replicated on our side even with the sample you provided.

Hi Peter, I saw the screen cast and the only thing I do different is go direct to that page off a link passing in a PageIndex in the querystring. When I pass in a PageIndex I get the error.

sample link:
http://localhost:49573/default.aspx?PageIndex=2

Hi Jorge,

It turned out that this is a known ASP.NET framework Client Validation Javascript Bug:
http://haacked.com/archive/2006/07/14/ASP.NET2.0ClientValidationJavascriptBug.aspx

For your case, the culprit is the empty space in the ID of the user control. Please, try modifying the code like so:

protected void RadMultiProfile_PageViewCreated(object sender, RadMultiPageEventArgs e)
       {
           string userControlName = e.PageView.ID.Replace(" ", "") + ".ascx";
           Control userControl = Page.LoadControl(userControlName);
           userControl.ID = (e.PageView.ID + "_userControl").Replace(" ", "");
           e.PageView.Controls.Add(userControl);
       }
