Hi,

I am working on hybrid application. Recently I am having an issue in WIndows 8, when app is starting,  the splash screen shows for a moment, then it hides and a white screen is displayed for a brief moment before the Keno Mobile UI shows. I have added AutoHideSplashScreen in Windows config.xml but it doesn't work in Windows phone. This configuration is working on Android, perfectly OK. I have upgraded Cordova to 3.7.0 version.

Can you give me any suggestions on how to remove white screen flash as the app starts, it looks unprofessional.

Thanks in advance.

Hi guys,

I'm using Telerik Q2 2015 with the release of Export to PDF (multiple pages) using ExportClientManager.

When a user clicked export, the save window popped up asking for open or save the pdf file.

If that user chose save then open the PDF file, everything is good.

But If that user clicked open the PDF then save the file, it showed error code 23 (Please see attachment).

Have anyone been had this issue and is there any solution?

I'm using adobe reader version 11.0.4

When adding new ComboBoxItems on the client (JavaScript), and specifically setting the "isSeparator" to true, it does not render correctly and instead still renders as an "rcbItem" in a standard "LI" element and the CssClass "rcbSeparator" is no where to be found (by inspecting the HTML).

categoryItem = new Telerik.Web.UI.RadComboBoxItem();
categoryItem.set_text("Separator");
categoryItem.set_value("Separator1");
comboItems.add(categoryItem);
categoryItem.set_isSeparator(true);

Does anyone know how to get Separator items to render correctly when adding them in JavaScript?

I have added a RadDropDownList control on my web page. Along with it I have added a standard Asp.Net button control. When I am clicking on the Asp.Net button the event associated with it is not getting fired. Can anyone tell why is this happening? Is it because of the Rad control? If so then what should I do to make the button click event to work properly?

Hi,

I have a RadCombobox on an aspx page that I'm trying to populate with one item at OnLoad using 

RadComboBoxItem newItem = getItem(id);
RadCombo1.Items.Add(newItem);
RadCombo1.SelectedValue = Request.QueryString["cid"];
RadCombo1.Text = newItem.Text;

After page finishes loading, while invoking RadCombo1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e), e has empty Text and loads data as if the box was empty.

Control on page:

<telerik:RadComboBox ID="RadCombo1" runat="server" 
                                        Width="300" MaxHeight="350" AllowCustomText="true" 
                                        MarkFirstMatch="true" 
                                        OnClientSelectedIndexChanged="OnClientSelectedIndexChanged"
                                        OnSelectedIndexChanged="RadCombo1_SelectedIndexChanged"
                                        EnableLoadOnDemand="true" EnableVirtualScrolling="true"
                                        OnItemsRequested="RadCombo1_ItemsRequested"
                                        ShowMoreResultsBox="true" Filter="Contains">
                                    </telerik:RadComboBox>

 

How can I set e.Text to my selectedItem.Text or invoke manually RadCombo1_ItemsRequested ?

I am very new to the Telerik controls, less then 8 hours.  I just spent several hours building a social network diagram using the D3.js library and now need to see if I can create a similar product with the Telerik controls.  Basically the diagram ​nodes need to show an image, that is stored on a local server, along with some textual ​information.   All data for the nodes and links would be stored in a local json data-set.  I would also need to add text labels to lines that link the nodes.

 

Can any one tell me if these requirements can be met using the Telerik controls, and any example code I could use to get up to speed.

 

Thanks

Perry

I am having an issue with Telerik RadGrid Control

The Grid control is configured allowing "paging and filtering"

When I write some text in the filter box the RadGrid control shows me the rows needed
but when I move from a page to another the radGrid shows me all the rows. 

It does not keep the filter I ask for


Help would be appreciated!

Does not seem like RadGrid.Rebind() is firing the NeedDataSource if NeedDataSource has already been executed on postback.  I am using a context menu on a grid row to duplicate the row but when I call the grid.Rebind() on the RadMenu_ItemClick it does not fire the NeedDataSource to rebind the grid. Has anyone else seen this?  I am using the Q3 2008.

Thanks,

Jason

I have added Forms authentication to my Telerik Website which is working fine.  When I add the code block for <authorization> the side will load but throw the following error before opening the login page:

 

JavaScript critical error at line 3, column 1 in http://localhost:61573/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:88fd0407-24cf-4abd-9df5-22f81b2bc835:ea597d4b:b25378d2;Telerik.Web.UI:en-US:33628d01-7007-4010-a8f6-f8f356bdff24:16e4e7cd:f7645509:22a6274a\n\nSCRIPT1002: Syntax error

 

If I remove the code block the site works but there is complete access to all the pages.

    <authorization>
      <deny users="?" />
    </authorization>

 

Not sure where to start looking.  I don't really want to create a session variable and redirect to the login page if not set if I don't have to.

 

This is a VS 2013 / .net framework 4.5 / C# web application.

 

Any thoughts?

 

Doug
