databinding a CustomDropDownEditor for a RadFilter

Hello,

I am having an issue using a custom drop down editor in the rad filter. When I set the value of my first filter criteria and click the link to add more criteria I lose the value of the first criteria I set. I think the issue has to do with when the handler is added for setting the value is after the binding already takes place.

Thanks!

Don

Export Grid to PDF without Full Trust

Hello,

I am trying to export a grid to PDF on shared hosting. From what I can tell PDF export needs full trust to write a temporary pdf to the server. I do not have full trust on the server.
Is there a way to export the PDF to MemoryStream and then write the MemoryStream's content using something like:
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Type", "application/pdf");
Response.BinaryWrite(....);
Response.Ende();

?

Spell check does not fire when click update all

I have a grid in web page. At that grid, I add an "edit all" button at command template. When user clicks it, all rows at that grid will be in edit mode. And another "update all" will update all user's change and update data into database. That works fine. Problem comes when I try to add spelling check function to it.

I add spelling check to "update all" and it works, and speeling check "update" button at a grid row and it works fine too. But when user clicks "edit all" button, all rows in edit mode. "Hidden" controls are needed for each row to hold "update" button client id, and radajaxmanager needs to add <ajaxsettings> dynamically too. I want to check with you the way I try to code is right, and please provide me some sample code to accomplish it.

Thanks

Image Directory loading time in IE

When using the RadFileExplorer in IE (and IE only…Firefox, Safari, Chrome all handle the following perfectly/quickly…only IE has the issue), if the directory has a lot of images in it (say, 50 or more, or perhaps the file sizes of the images are quite large), the launching of this tool will literally FREEZE the IE browser for 30-60 seconds (IE's windows-bar displays "(Not Responding)" if you try to click anywhere in the window). The RadEditor is a part of our online application where significant numbers of fairly novice users utilize it to build simple email content. So…the patience level of these authors is very low, and they often will simply attempt to close the browser, as they believe the system has crashed….when in fact, if they just waited 30-60 seconds the problem would go away.

Acces to a Nested RadRating Property in JavaScript Function(Handling OnClientRated)

Hi,
After writing OnClientRated Function for a RadRating (A nested one) as below:

function OnClientRated(sender, args)

{

...

}

How Can I Convert sender to RadRating here, My goal is to access a property of my specific RadRating Control(I'm using RadRating in a DataList Control ). I know that I can do it in ItemDataBound event of DataList, But it's not good enough considering that I have to use the value here in JavaScript Function(I'm going to use it as a QueryString Value in order to redirect to a page shown in RadWindow).
Would you please help me out?
