Hi there,

 In the FormCreated event of RadScheduler I added a event handler for ResourceType combo box. Here is the code.
What I am trying to achieve is that when I select an item in the combo box it will automatically populate other textbox on the Advanced form.


 This issue is that when I use SelectedValue to retrieve the value in SelectedIndexChange event it returned something like /wECAQ==
I am not sure where this value from. There is nothing wrong with the data binding. The expected value should be integer.

I also tried to use client API to retrieve the value. I got same result.

How could I retrieve the value from the combo box?

Thanks

Hi,

I'm trying to use chart Zoom event in Asp.net. How can I obtain x-y values from Chart Zoom event args ?

First of all I  bind a data to my chart after user zooms, according to the zoom args I want to bind another data source to chart because of performance issue. How can I manage my plan ?

tnx.

Hi,

I am trying to filter the allowed files to upload depending on the media library that has been selected. (docs, images, videos, etc)

I have the radasyncupload control in a modal window. Switching between media categories is done with a button for each cat. I tried to change the AllowedFileExtensions property there for each media type but it didn't work. Should I set it somewhere else?

Also, how could I change FileFilter description and extensions in codebehind? is it even possible? i tried using Eval("desc/ext") but I have must missed something. 



Any suggestions would be appreciated it. I am thinking in doing a radasyncupload control for each media type and just hide/display accordingly but I would like to avoid that.

Thanks

We are trying to upload and process some excel files; there is no need to keep the file, so ideally we'd just like to keep them in memory and do what is necessary without storing the file. We are using the Excel Data Reader, and that part of it is working correctly if we use the TargetFolder setting and save the file. However, if we try to process using only the filestream, there are problems.

The documentation says that the InputStream property returns a system.io.stream object, which is what the reader expects, but when we try to load that object into the excel data reader, the error is;

"Unable to cast object of type 'System.Web.HttpInputStream' to type 'System.IO.FileStream'."

The code is


We've tried casting the inputstream to a system.io.stream object directly, but that also throws an error. The code is using an external class to do the processing, since it's something that is done from various places within the application.

Any suggestions? Anyone out there used RadUpload and processed Excel files on the server in this way?
