I have a RadListView and a RadDataPager. Ive managed to set it up using standard paging but I want to use custom paging.
In standard mode, whenever I select the 'next' button, it pages the ListView, but then freezes.

I cant see how I would implement my own custom paging.

Im retrieving a list ob objects using LINQ
I pass in the current page and the pagsize, and use 'skip' in the LINQ command

protected void RadListView1_NeedDataSource(object sender, Telerik.Web.UI.RadListViewNeedDataSourceEventArgs e)

{

List<Business.Logic.BusinessObjects.AssociationRequest> lst = new List<Business.Logic.BusinessObjects.AssociationRequest>();

lst = requestManager.GetArtistRequests(this.CurrentArtistID, false, this.CurrentPage, this.PageSize);

if (lst.Count > 0)

{

this.RadListView1.DataSource = lst;

}

else

{

if (RadListView1.DataSourceID == "")

{

RadListView1.DataSource = new string[] { };

}

I want to set the current page whenever I select 'next' or a page number from the datapager, how can this be done?

[Solved] Uploads only in TempFolder

Hi,

my AsyncUploader just saves the files in the Temp Folder - It does not restore it in the TargetFolder with the original name and extension. I tried the TargetFolder with
in .aspx file:

TargetFolder="~/dateien"
and

TargetFolder="./dateien"

and also in code behind:

rauUpload.TargetFolder = Server.MapPath("~/dateien");

If the folder "dateien" does not exist - AsyncUploader does not create one and also does not throws any exception.
I also tried to create the folder "dateien" and gave "Everyone" "Full Access" (Windows 7)

Everything else works fine - AsyncUploader also "uploads" the file - but just into the temporary folder.

Another question:
My radProgressArea does not show the Speed - its everytime 00.00
and the estimated time is also everytime 00:00:00

I hope someone can help me with these problems : )

Best regards,
Raimund

[Solved] Need explanation on radmenu with css sprites

Hi forum!

I would like some brief explanation how can i work with the css sprite for the radmenu button images. Currently im doing an image for each button (main and sub) and each one ias abou 2 kb witch is very bad i think. I know how css prite works (basic) and i would like to grab a 1px width image and fill the background of the items (radmenuitems) since i cant call the background-image and back-ground-repeat.

Also, i would like to know what is better in terms of performance to a website, use background-image with background-repeat and put the text as image or use background-image with background-repeat and use the normal radmenu text property (my problem here is that i can't find the font i want that is Microsoft Sans Serif that i use in photoshop)

Many thanks,
FEST

Content formatting being removed

Hi All,

We are using the aspdotnetstorefront system which has a rad editor as part of its admin system for the saving content.

We have been supplied some javascript when we paste this into the editor and save it to the system, on it's return the javascript block has a lot of the line breaks and some white space removed.

When this is used on the front end of the site it doesn't work because of the new formatting given to the javascript.

I have added contentfilters, stripformattingonpaste and stripformattingoptions.

<tcontrol:RadEditor runat="server" AllowScripts="true" ContentFilters="None" StripFormattingOnPaste="NoneSupressCleanMessage" StripFormattingOptions="NoneSupressCleanMessage" RadControlsDir="rad" id="radDescription">

However these still allow the javascript to be condensed and on some of the settings it even goes as far as allowing the javascript to render dynamic content to the radeditor box.

Does anybody have any advice which they can share?

Many thanks,

Mark

Telerik support site is not working !!!!

Hai,

I am using Windows 7. Your support website is showing only black screens. Demos, Documentation and Knowledge Base are not working. It shows a javascript with blank screen. I tried it in IE 8, Mozilla, Google Chrome, Opera. Its not working in any of these browsers. There is no firewall or any such security issues as no other websites have this issue. There is no javascript issues as javascripts in all other websites are working correctly. Also it is my development computer, I am sure that, there is no issue with javascripts in browsers as my own javascripts works properly. It is the problem with telerik website itself. Please solve it at the earliest.
