Saving Check with WebService on demand load

I'm trying to figure out the best way to store the check state of nodes. I have the treeview being populated using a Web Service. I've got the treeview populating child nodes on selection of parent in javascript.

The particular scenerio I'm havving issue with is:
1.   Expand a parent node
2.  Check some children
3.   Collapse parent node
4. Reopen parent node & the selections are cleared (because they're reloaded in the web service)

I will also need to get all the checked values, regardless if they're expanded or not.

I have roughly 4,000 child nodes that are populated, so server-side code is really not an option. Can I store the checked state in the web service, when an item is checked & then set the checked value on expand?

Thanks for your help.

localization & sorting of grid

Good day!
I'm new for ASP.NET AJAX and maybe it will be a very stupid question, but I try to add sorting and localization of the grid messages to my grid but I have no results =(
about localization:
I've added the folder named App_GlobalResources to my project, and added RadGrid.Main.resx & RadGrid.Main.ru-RU.resx with needed strings to this folder. (like I saw here http://www.telerik.com/help/aspnet-ajax/localization-global-resources.html)
But there is no effect =(
Should I write some usings of this resourses on the page with my grid? Or should I do something else?

about sorting:
I added AllowSorting="true" to my grid. Shoud I do something else to make me columns simple sortable? Now when I click the name of column I see the busy indicator for a while but nothing happens =(

maybe you can show me some sample with localization and very simple sorting?

great thank to you!

Load-On-Demand RadComboBox does not raise CustomValidator.ServerValidate when blank

Following this documentation, I am requiring that a value be set in a Load-On-Demand RadComboBox. Both the client and server validation events are raised when text has been entered. If there is no text, neither the client nor the server validation events are raised. Also of note, MarkFirstMatch = True, ShowMoreResultsBox = True, and EnableVirtualScrolling = True.

I was able to fix this problem by adding a RequiredFieldValidator in addition to the CustomValidation. Is this by design?

ajaxRequest and radopen

I have a client-side handler for OnClientClick for a button. Here is what it looks like:

function OpenReportWindow(nCompanyID, nDetailsID) {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequest("Save");

var wnd = window.radopen("/CharitableSponsorshipsReport.aspx", null);

//wnd.setSize(750, 550);

return false;

}

Currently the server side handler for the ajaxRequest has all of the code commented out to help solve the issue. What I see happen is that the radopen window shows and then immediately closes. If I comment out the ajaxManager.ajaxRequest code the window shows and stays. Why is this? Is there a way to do the ajaxRequest and then the radopen? The ajaxRequest server handler performs some tasks that the aspx page needs when it shows.

Are there any file download size/type limits with FileExplorer?

Hi,

Looking to replace a web download system with RadFileExplorer and was wondering if there are any limits on the file size downloaded and what types of files can be downloaded? I need to be able to download large video files (some over 1GB) and possibly other files (excel, word, text, etc.). The demos seem to just use images. My current solution loads the file into memory so it can control the file name and content type to force the download (so it doesn't open in the browser). But my system doesn't work with loading large files into memory and is not very efficient.

Please advise,
-Jim

Force empty directory

Hello,

My explorer root directories are based upon a user managed config file. It can happen that the directory is incorrect/removed whatever. this creates an ugly error;
How can I show a userfriendly message that the directory does not exist?
And/or how can I force the explorer to show an empty directory?

I tried
return new DirectoryItem("Invalid directory", string.Empty, "/", "tag", PathPermissions.Read, null, null);
but that shows the root directory.

Any ideas?
Thanks

RadGrid Export to CSV or Excel - how to export to multiple sheets

Hello,

I have RadGrid binded to the data source (DataSet). DataSet have 2 tables unrelated to each other.
I want to export each table to separate sheets. Is it possible?

Another question - can I change sheet name? Right now it is derived from file name. I want to be able to specify it myself.

Thank you,

Andrei

Does a nested view demand a seperate datasource?

I'm using a nested view, where all the data (columns) required already exist in the master grid's data source, so I do not need to use a separate datasource or query for the nested view.
However, when I expand my nested view for a row, it always displays data for the FIRST row no matter which row I expand.

Frustratingly my edit form, which basically performs the same function, returns the correct data for the selected row.

Have Telerik accounted for the possibility that all the data required can come from the grid's data source, or is this a limitation of the control?

Thanks,

Shane
