I'm using RadAsyncUploader (latest version of course) to upload multiple images to a page.

However, i'm getting FielNotFoundException in the FileUploaded event all the time and
after some investigation i can see that the file is uploaded ~App_Data/RadUploadTemp with a random generated name.
Later when the program steps into the FileUploaded event it tries to find a file with another  generated name.

What makes this a bit more complicated is that sometimes the filename it tries to access is the uploaded one.

Can you assist me with this issue?

Hi, I have master child grid and export functionality in both parent as well as child grid. 
I do data binding in code behind. Export from the parent grid works fine but when user clicks on Export to Excel in child grid, it throws following exception.

Hi,

Not sure if this is the correct forum for this sort of question, but here goes:

I have a login page that uses the FormsAuthentication logic to secure the website. It is set up to disallow any access when you are not logged in (other than the login page).

That means literally every file is inaccessible, including .css files and images. Those I need on the login page, I have set up as exceptions, using the <location path="css/login.css"> setting in web.config.

Now, apparently the site's Telerik skin is not active either, so I assume I need to set it as an exception as well, but since all of that is stored within the Telerik dll, I don't know how to allow it.

Any ideas?

Hi,

I would like to show only 2 appointments in each time-slot for  Week-view. If  the number of appointments exceeds 2,  I want it to show more button as in Month View.

In Day-view, I want the time-slot to expand vertically/show scroll bars  within time-slot  as in time-line view. I want  the time-slot to expand vertically to fit all appointments rather than squeezing the appointments.

I would also like to give a bright orange border to  whole column  representing today's date in month and view . Is it possible to acomplish above objectives, if yes, how can I do it?

Thanks,
Prava

Okay, i'm doing something very simple, so i must not be understanding something.

Goal: Show a Table Row when the checkbox is checked, hide it when it's unchecked.

Javascript = The row i'm referencing exists with that ID. Gives me the same id if I use

<%=rowRelationship.ClientID%>

 

TelerikRadButton Code:

The event is firing, but i'm getting an Object Expected error on the getElementById call, which I don't understand, the Row exists with the id.

Thanks for any help, (and i wouldn't be surprised if there is something i'm not doing right w/ my javascript)

I've looked around the forums a bit and can't find an issue that relates exactly to my scenario.

I've got a Radwindow, with 2 buttons on,

A cancel button (OnClientClick = 'CancelEdit')
and a save button (iniates postback, runs some server side code then calls the CloseAndRebind method with ClientScript.RegisterStartupScript. )

This all works, however, when i click the 'save and close button' it closes the radwindow, refereshes the control on the page below (in this case a listview) but then the radwindow reopens, and i'm not sure why.

Hello,

I have a question, currently I am working to add new clients. I created a button on the Advanced form for this. When the button is clicked there opens a new window with the windowmanager. The Window manager is in Agendacontrol and not in advancedform.

When they submit the client I want to add the data to the advanced form via Javascript. 


Currently I have this. The agendacontrol execute this when the user has finished creating the new client. So, what I need now is to add that 'cityname' to the advanced form. Does anyone of you know how to do this? For example, I want the cityname to the subjectbox in the advanced form. 

Thanks in advance

Edit: 
I fixed it , solution: e._formElement.getElementsByTagName("INPUT")[0]; Thnx for the help :)

Hello,
I have all my columns built runtime using TemplateColumns. Now I want to implement in-place editors and I can't do EditorItemTemplate. Forum search refers 2-3 years old solutions which I cannot implement. Can you please help?
Thank you.

My application is very simple, it has login, registeration and schedular control.

Every thing was working fine, without any error.  then all of sudden

Radscriptmanager started throwing error as seen in below screen shot.

I restart VS2010, Empty Browser Cache, restarted PC.   but stil its the same error.

What went wrong ?

Hello,

I have a telerik:radgrid which contains the following column
<telerik:GridBoundColumn DataField="LITIGATE_PERSON_CIF" DataType="System.String"
                    HeaderText="CIF Καθού" UniqueName="LITIGATE_PERSON_CIF" DataFormatString="{0}">
                    <HeaderStyle Width="70px" />
                </telerik:GridBoundColumn>

The type of LITIGATE_PERSON_CIF column in DB is varchar(50). An example of data at this column is "9999940374268002".

When i export to excel this grid, i get the value 9999940374268000 at this field.

Should I use another format?

I thing that somehow it rounds the data. How could I avoid that?

Regards,
Peny
