Membership Provider <location path="Telerik.Web.UI.WebResource.axd">

I converted an ASP.NET 3.5 web site into ASP.NET 4.0 and have run into some problems. When I don't put <location path="Telerik.Web.UI.WebResource.axd"> in the web.config, the Membership Provider works and I get the Microsoft JScript runtime error: 'Telerik' is undefined error. When I put <location path="Telerik.Web.UI.WebResource.axd"> in the web.config, the I don't get the Telerik error, but the Membership Provider no longer works.

Need to show contents of dynamically created tabs on page load

Hello,

I have a TabStrip with a RadMultiPage that is loaded dynamically based on a table in my database. This TabStrip can consist of three levels of tabs (parent, middle-child, and bottom-child).

Here's the code that generates the tabs:

if (!IsPostBack)

{

rtabstripTabs.DataFieldID = "tabID";

rtabstripTabs.DataFieldParentID = "parentTabId";

rtabstripTabs.DataTextField = "tabLabel";

rtabstripTabs.DataValueField = "filePath";

rtabstripTabs.DataSource = tabs;

rtabstripTabs.DataBind();

}

Here's the HTML for the TabStrip:

<telerik:RadTabStrip ID="rtabstripTabs" runat="server" OnTabClick="rtabstripTabs_TabClick"

MultiPageID="rmultipageUserContol" EnableEmbeddedSkins="False">

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="rmultipageUserContol" runat="server">

<telerik:RadPageView runat="server" ID="rpageviewUserControl">

</telerik:RadPageView>

</telerik:RadMultiPage>

The "filePath" is a link to user control pages that will be displayed when the user clicks on a tab.

I'm trying to figure out how to load the user control content in these two scenarios:
1- When the tab (page) first loads I want the content of its user control be displayed automatically. Since the TabStrip is dynamically created the name and value of this tab could be different.

2- When the user clicks on subsequent tabs I want to display the content (user control page) of the first child tab (this could either be a child on the 2nd level or a child on the 3rd level. The tab levels are also dynamic, and depends of the content of the table in the database). I know how to display the content when the user clicks on a tab that has no children.

Any help will be very much appreciated. I am a new Telerik user, and I have not been able to figure out how to do this on my own. Thanks.

RadGrid multiple filter from Javascript

Im trying to filter Grid with Javascript

<telerik:radgrid ID="RadGrid1" runat="server" AutoGenerateColumns="True" AllowSorting="True" ShowGroupPanel="True" GroupingEnabled="True" DataSourceID="SqlDataSource1" OnExcelMLWorkBookCreated="RadGrid1_ExcelMLWorkBookCreated" OnGroupsChanging="RadGrid1_OnGroupsChanging" AllowFilteringByColumn="true">

<PagerStyle Mode="NextPrevNumericAndAdvanced"></PagerStyle>

<ClientSettings ReorderColumnsOnClient="false" AllowDragToGroup="True" AllowColumnsReorder="false">

<Selecting AllowRowSelect="false"></Selecting>

<Resizing AllowRowResize="False" AllowColumnResize="False" EnableRealTimeResize="True"

ResizeGridOnColumnResize="False"></Resizing>

</ClientSettings>

<GroupingSettings ShowUnGroupButton="true"></GroupingSettings>

</telerik:radgrid>

Here is Javascript

var grid = $find('ctl00_MainContent_RadGrid1');

var master = $find('ctl00_MainContent_RadGrid1').get_masterTableView();

master.filter("Type", 'SWITCHED', "EqualTo");

master.filter("Resource", 'POWER', "EqualTo");

Only the second filter applies but not first.

Please suggest how to apply both, and it would be better suggest n filters

RadAjaxLoadingPanel center viewport


I have a RadAjaxLoadingPanel specified as follows in my master page:

<telerik:RadAjaxLoadingPanel id="RadAjaxLoadingPanel1" Runat="server" IsSticky="true" skin="Silk" InitialDelayTime="250" Style="position: absolute; top: 0; left: 0; height: 100%; width: 100%;">

</telerik:RadAjaxLoadingPanel>

my understanding is that this code will center the panel on the screen. However, it appears it instead centers it in the context of the entire document. That is, if the page is two screens long, the panel will appear cut in half at the bottom of the screen. Is there a solution to make this work as expected?

Disabling Other Controls While Uploading

Hello! I’ve been using the RadAsyncUpload control and it’s been working great. Provided is an image of what my screen looks like. As you can see, I’m using RadAsyncUpload’s ruBrowse button to both upload the files clientside and then force a postback in order to upload the images to the database serverside (one button does all).

However, circled are other controls I’m using on my site. The problem is that when the client clicks “Upload Pictures,” and the files get uploaded clientside (as you can see with the green dots), it takes a little time to insert them into the database (serverside). Currently, without the implementation of a wait cursor, the client is able to click any of the other controls on the page:

- (RadTabStrip) Click the Entry Content tab which stops the uploading from happening.

- (Asp Buttons) Click Save/Cancel, which leaves the client in a bad state.

- (RadAsyncUpload) Click the “Upload Pictures” button again to upload more pictures.

I was wondering if there was any way to be able to disable other controls while the uploading is still happening?
