Hi Guys,

I need help in saving a state of a control..
I want to put a button "SAVE" when you click on that, the current state of the controls like Radgrid data, Rad filter values, Rad treeview nodes should be saved in a file format. And when you Open that file the page should be loaded and User can work on the page as usual..IS this possible in TELERIK..??

THANKS IN ADVANCE

How can i do conditional ajax updates from a tree view in a usercontrol

Hi I am working on a project which has a user control containing a Telerik Tree View on a page, with an information panel on the main page. The user can traverse the tree in the usercontrol which contains folders and items, and if they click an item it loads the information for that item into the main page.

This is handled by using delegates in the user control, and subscribing to that bubbled event in the master page.

I have wrapped this up with a RadAjaxManager, and I want the information panel to have a LoadingPanel displayed over it ONLY when an item is selected, but not a folder. In the user control we do not raise the event if the item is a folder.

I haven't had any luck with this.

I have created a project which displays this behaviour. You can see that when the folders are clicked they also display the loading panel over the main panel, which is what I want to prevent. This is because in production environment, clicking a folder expands the folder but does not reload the main information, but having the loading panel put over it gives the user the impression that it is reloaded.

Can you please help me get this working?

My project contains two files, Default.aspx and FolderView.ascx

radupload , FileExists , filename

hi

Im facing here some dilema , I am using the radupload control to push some files to the server , they will be dropped in some folder i defined in the control with TargetFolder , i have subscribed the FileExists event handler to check if some file with the same name exists on target everything is fine till here, the thing is that when a file is renamed to not overwrite another in the destination folder i cannot update its new name on the radupload control let me explain

void RadUpload1_FileExists(object sender, Telerik.Web.UI.Upload.UploadedFileEventArgs e)

{

int counter = 1;

UploadedFile file = e.UploadedFile;

string targetFolder = Server.MapPath(this.RadUpload1.TargetFolder);

string targetFileName = System.IO.Path.Combine(targetFolder,

file.GetNameWithoutExtension() + counter.ToString() + file.GetExtension());

while (System.IO.File.Exists(targetFileName))

{

counter++;

targetFileName = System.IO.Path.Combine(targetFolder,

file.GetNameWithoutExtension() + counter.ToString() + file.GetExtension());

}

file.SaveAs(targetFileName);

file.FileName = System.IO.Path.GetFileName(targetFileName); // <---- this line here

}

i need this because later i loop through uploaded files , and do some more processing on them ... i can think on several ways to go arround this but isnt conceptually wrong not beeing able to update the filename ???

thanks for your time , and i hope im not missing something obvious

The SelectedItems collection is not being emptied with the Clear() method

I’ve tried the following to clear all selection from a TreeList:

tlConfig.SelectedItems.Clear()

Nothing was removed from the selected collection. I then used the brute force method and it works:

For Each selectedItem As TreeListDataItem In tlConfig.SelectedItems

selectedItem.Selected = False

Load-On-Demand error

I'm not sure if anyone's asked about this specific issue before but I wasn't able to find it when I searched. I'm trying to use a combobox as an autocomplete textbox using EnableLoadOnDemand but when I type into it it keeps giving me the javascript error: "There is no assigned data source. Unable to complete callback request." I was working when I first put it in but I can't seem to get it back to the way it was when it worked. Is there anything anyone can think of that I can look at as to why it wouldn't be working. These are the settings that I am setting in the codebehind.

combo.EnableAutomaticLoadOnDemand = true
combo.ItemsPerRequest = 15
combo.EnableVirtualScrolling = true
combo.ShowMoreResultsBox = true
combo.ShowDropDownOnTextboxClick = true

Scheduler displays the appointments correctly, however, I am receiving an 404 error from a WebResource request.

I managed to decrypt the request parameters and found that it says:

pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Office2010Blue.Scheduler.rsAppointmentBg.png

Anybody has a clue how can this 404 error be corrected?
