Does MaxJSONLength in web.config affect RadTreeView?

Hello,

I have a RadTreeView control that fails with the following error, if I populate it with a large (say, 2000) number of nodes:

"Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

I am able to set the maxJsonLength property in the web.config of my application - however no matter what value I give to maxJsonLength (up to Int32.MaxValue), the above error appears. I've tried every combination of maxJsonLength value and number of nodes in my tree.

In the Microsoft docs (http://msdn.microsoft.com/en-us/library/system.web.configuration.scriptingjsonserializationsection.maxjsonlength(v=VS.90).aspx), it says:

"The value of the MaxJsonLength property applies only to the internal JavaScriptSerializer instance that is used by the asynchronous communication layer to invoke Web services methods."

So now I'm thinking that RadTreeView doesn't pay attention to maxJsonLength. Is this correct?

Thanks,
Leigh

Default height of a RadScheduler display the TimeLine view?

How can I set the default height for a RadScheduler that's using the timeline view? I don't want to set a fixed height, cause I want it to grow vertically when I add resources.

Thanks

RadDateTimePicker and invalid content

Hi,

When I enter some invalid data into a RadDateTimePicker, the field is marked as invalid (warning triangle and red border)- That's nice and fine.
But when I submit the form, however, the page is considered as valid (this.IsValid returns true) and the postback is executed.

How can I prevent the form to do a postback on invalid data?

Thanks in advance.

Can't select items, just text

Hi,

One of my users is having an issue with selecting items in a RadListBox. When they click on an item in the ListBox, characters in the text of the item is highlighted, but the actual item is not selected. It is very strange behaviour. This problem is occuring in all browser, but only on one particular computer. I have not been able to replicate the problem myself It has me completely stumped. Does anyone have any ideas what could be causing this?

See the attached screenshot for an example of the problem. The user has clicked on the fifth item in the listbox (Hulland) but as you can see the text "Hulland" gets highlighted, but he listitem is not selected.

Thanks
Andrew Dixon

Hello ,

I have a RadGrid in my page. The PagerItems are created using PagerTemplate.. I have asp buttons, ComboBox, RadNumerictextbox and a NumericPager. The code for pagertemplate is described below. I am using an ASP Panel for placing NumerPager in Pagertemplate.

In the ItemCreated event function i have created the Numericpager. Following code describe that functionality. I also attached a screen shot about that pager. Now i come to my problem, I want to handle the click events of that Pager. When i click the page numbers(1 2 3 4) i want to do some process. How can i handle this events from client side using javascript and from server side using C#

void radgdSuccessionList_ItemCreated(object sender, GridItemEventArgs e)

{

try

{

if (e.Item is GridPagerItem)

{

GridPagerItem gridPager = e.Item as GridPagerItem;

Control NumericPagerPlaceHolder = gridPager.GetNumericPager();

Control placeHolder = gridPager.FindControl("NumericPagerPlaceHolder");

placeHolder.Controls.Add(NumericPagerPlaceHolder);

}

catch (Exception)

{ }

}

Please give me the solution for this problem.

Velkumar.

Styling Databound RadMenu

I'm playing around with the Q1 2011 Rad menu.

I'm able to easily style a static menu without problems, however, now I'm looking at a radmenu bound to an SQLDataSource. I've gone through several example (however have not tried adding C# code yet).

Can someone point me in the direction to successfully styling and configuring the radmenu items in this scenario (i.e. hover over background image, normal background image, etc)

Thanks!

How can I stop RAD Editor from applying stylesheets to the content pane?

I want to use a stylesheet on a page that contains a RAD Editor control. I do *not* want RAD Editor to take that stylesheet link and add it to the content iframe. Seems like it should be simple to do, but nothing seems to work. Here's my code:

<telerik:RadEditor ID="edtMe" runat="server" Skin="WebBlue" Height="600px" Width="100%"
    OnClientLoad="OnClientLoad"
    ContentFilters="RemoveScripts, FixUlBoldItalic, FixEnclosingP, IECleanAnchors, MozEmStrong, ConvertToXhtml, IndentHTMLContent"
    StripFormattingOptions="MSWordRemoveAll" OnClientPasteHtml="OnClientPasteHtml" SpellCheckSettings-AllowAddCustom="false">
    <CssFiles>
        <telerik:EditorCssFile Value="~/CSS/blank.css" />
    </CssFiles>
    <Content>
    </Content>
</telerik:RadEditor>

Using the CssFiles is the correct way to make this happen, right? Not only are the page styles still being linked in the content iframe, but blank.css is *not* being included. The content area iframe's head element looks like this:

<head>

<style></style>

<link href=

"/MvApp/WebResource.axd?d=ZMA9Nyl6OV-krKpF_AxH2ehr5-QYUrzahQKPDXQJIRbD47XVXXyGnhGGRWxBtFdN4Rbj-vRYXe6815fiQCJqONv8yYpz-mHqbT_xLF5uFGZiBNGg4prjb2HEQSOTlJ3QqpKfVUx83-JpV7QlzOL4nw2&t=634203434222846081"

type="text/css" id="RADEDITORSTYLESHEET0" rel="stylesheet">

<link href="./CSS/Styles.css" type="text/css" id="RADEDITORSTYLESHEET1" rel="stylesheet">

<link href="App_Themes/Basic/MainMaster.css" type="text/css" id="RADEDITORSTYLESHEET2" rel="stylesheet">

<link href="App_Themes/Basic/Menu.css" type="text/css" id="RADEDITORSTYLESHEET3" rel="stylesheet">

</head>

You'll notice that blank.css isn't there and Styles.css (the stylesheet I want on the page but not in the content), is. Any thoughts?

I'm using RAD controls v2010.1.519.35.

Localization problem with Undo\Redo actions

Hi,

I cannot localize such undo\redo actions like "Enter", "Insert HTML", "Resize", "Set HTML", "Move".
I have tried to define these keys in localization file (RadEditor.Tools.*.resx) but with no luck. Clearing browser cache and restarting application didn't help.
At the same time if I change any values from defined keys changes are shown in the editor.

Please help.
