UserControl disapears after the second postback (ajax request)

Hi,
I build an aspx page which contains only one RadTabStrip and its RadMultiPage.

In the page_load event (in the behind code), I build dynamically the RadTabStrip and the RadMultiPage

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

string[] arguments = Session[SessionParameterName.LISTDOCTOVISU] as string[];

for (int i = 0; i < arguments.Length; i++)

{

AddTab(arguments[i]);

AddPageView(RadTabStripDocView.Tabs[i]);

}

For each value the named Session field, i create a RadTab and a PageView, like in the live demo example.
I also implemented the function AddTab and AddPageView

private void AddTab(string codeDoc)

{

RadTab tab = new RadTab();

tab.Text = codeDoc;

tab.Attributes.Add("CodeDoc", codeDoc);

tab.Value = codeDoc;

RadTabStripDocView.Tabs.Add(tab);

}

private void AddPageView(RadTab tab)

{

RadPageView pageView = new RadPageView();

pageView.ID = "PageView_ID_" + tab.Value;

pageView.Attributes.Add("CodeDoc", tab.Value);

RadMultiPageDocView.PageViews.Add(pageView);

tab.PageViewID = pageView.ID;

}

and the event PageViewCreate on the RadMultiPage

protected void RadMultiPage1_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string codeDoc = e.PageView.Attributes["CodeDoc"];

if (!string.IsNullOrEmpty(codeDoc))

{

string userControlName = "usercontrol/ViewerDocument.ascx";

ViewerDocument userControl = Page.LoadControl(userControlName) as ViewerDocument;

userControl.ID = e.PageView.ID + "_ViewerDocument";

userControl.CodeDoc = e.PageView.Attributes["CodeDoc"];

e.PageView.Controls.Add(userControl);

}

My user control content:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ViewerDocument.ascx.cs"

Inherits="Class_iWebAsp.usercontrol.ViewerDocument" %>

<telerik:RadCodeBlock runat="server" ID="PreviewDocumentForMultiDocCodeBlock">

So When I click on the RadToolBarButton the ajax Postback is well fired, the second times is a not an ajax postback it's a simple postback, the RadAjaxManager is not on ajaxrequest, and my usercontrols disappear.

Could you help me?

How do I change button labels in upload panel?

Hi - my users are asking me to change the text on the buttons in the upload panel to say "Browse" instead of "Select" - on the RadUpload control this would be a <localization> setting, but this doesn't appear to be the case with the FileExplorer's upload panel - what files/settings do I need to look at to make this change?

FileExplorer

WebResource.axd - 404 error

Hello everyone,
I posted few days ago about problem with radmenu: http://www.telerik.com/community/forums/aspnet-ajax/menu/radmenu-issue-after-deploy-on-production-machine.aspx

But really rad components didn't work at all, because they couldn't to load CSS. Every request to WebResource.axd returns 404 error.
I tried all advices from there http://www.telerik.com/help/aspnet-ajax/web-resources-troubleshooting.html. But it still doesn't work.
I use IIS 7 on production server, and telerik dll lib located in bin directory. After few hours after deploy all begin work fine, but after every update - we need to wait, so we lost too many time after every fix. Please advise, what I should to do to save this time?

Remove the NOT AND and NOT OR

Hi,

Many users have asked how to remove NOT AND and NOT OR from the dropdown. I have tried an easy way and it works.

            FilterControl1.Localization.GroupOperationNotAnd = "";
            FilterControl.Localization.GroupOperationNotOr = "";

Don't use Null - it will not work.

The same way can be used to remove the operators (for example: IsEmpty and NotIsEmpty) from the dropdown.

            FilterControl1.Localization.FilterFunctionIsEmpty = "";
            FilterControl1.Localization.FilterFunctionNotIsEmpty = "";

Thanks
Bruce

RadFilter. Prohibit some boolean operators in filter expressions

Hello Telerik team,

First of all, thank you for bringing web components, to the next level!

I would like to ask, whether there is a way to remove some boolean operators, e.g. all except for AND, to simplify filter expression? We need to simplify end user experience, hence would like to remove unnecessary options (OR, NOT OR, NOT AND).

Thanks in advance!

Ivan
