OnClientFileUploadRemoving and args.get_fileName()

Hi,

I found out that the args.get_fileName() function returns the correct filename if you are removing an already uploaded file.
But if you cancel a running upload this function returns the following:
"[filename]<span class="ruFileProgressWrap"><span style="width: 0.8%;" class="ruFileProgress ruProgressStarted"></span></span>"

Client-side Scheduler Proposal

Hi there,

I am wondering if something is possible with the Scheduler. I have thought about it myself and I am fairly sure of where to start and that it is indeed possible, but I am hoping others can confirm and share their experiences with doing something similar, or point out troubles I am likely to run in to.

I would like to use the Scheduler totally client-side, storing all appointment information on the client, and allowing the user to save changes by clicking a "Save" button. Only then will the changes be sent to the server, processed and database updated etc. I am reasonably familiar with the client-side javascript API, and can imagine storing appointment data client-side (hidden fields and/or cookies), or perhaps using AJAX calls to transmit data each time a change is made for batch processing later, but if someone can share their thoughts on this it would be greatly appreciated.

Is this possible?

Thanks,
Ryan.

set_primaryIconCssClass?

Is there a way to set the PrimaryIconCssClass clientside yet by any chance?

Don't see it in the docs, so I'm doing some jQuery manipulation instead...but it'd be nice to change a couple lines of code down to 1.

What to do when formsauthentication expires on ajax calls?

This affects lots of ajax functionality, but for this example, I'll use the ajax spell checker in the radeditor. I had some users complain that the spell checker seemed to 'freak out' every now and then, and I traced it to this.

To reproduce, use forms authentication with a login URL and a short timeout of 1, (just so you don't have to wait long for this test).

    
                    <authentication mode="Forms">  
        
                        <forms name=".userauth" loginUrl="IC/Login.aspx" protection="All" timeout="1"/>  
        
                    </authentication>

Wait at least a minute then click on spell check. You should get this JavaScript error:

Microsoft JScript runtime error: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.
Parameter name: data

This happens because the forms auth. timed out and the ajax request was redirected to the login page. The login page is HTML and not JSON, so MS ajax throws the above error. The spell checker is left onscreen and cannot be closed as both Finish and Cancel are disabled.

My question is: is there anything that can be done for this, like catching the error somehow, and throwing up a login dialog?

What I have done in the past is ping the server every 10 minutes with JavaScript to keep formsauth. alive. I'd like to avoid that technique if possible as it didn't seem to be reliable all the time, and it left users logged in too long.

Thanks

Persisting expanded nodes in master page

I am having trouble using the treeview in a master page as everytime there is a postback the masterpage reloads and the treeview reverts to its loaded state where none of the nodes are expanded.

I have looked on the forums here for a solution but i havent found one so far.

Is there a solution for this?

Many Thanks

When the repeaters were filling in the second tab, the scroll bar is displayed.

I move to the end of the scroll bar and check the last checkbox from the repeater.
when I check the check box after scrolling, the header (the RadPane with the Id =topane) disapears.

Have you already seen this problem?

radtextbox and captcha validation

I would like to get validation to work on a form that has radcaptcha, and a radtextbox included. I cannot get it to work unless I use asptextbox with clientsidevalidation disabled.

I have made sure that the validation group is set the same for both the radtextbox and the captcha control, but the captcha control never seems to validate - even through the radtextbox works just fine.

Is there anything i can do to keep client side validation of the controls that can do it, and validate the captcha control on the server side?

Refresh RadTreeView via RadAjaxManager causes loss of functionality

Hello,

I have a control that loads a RadTreeView using an object as the source and performing on-demand loading of child nodes via the OnNodeExpand event. I also use a RadWindow to allow users to edit the tree nodes. When the user saves their changes on the RadWindow, it fires an ajax event using javascript which then uses an ajax request to update the node in the tree. This is working very nicely.

However, when the user finishes editing and closes the RadWindow the RadTree no longer functions properly. The OnNodeExpand event is no longer firing when trying to expand a node and the OnClientMouseOver I was using to display tooltips is not effective below the first level of nodes. I've tried adding the NodeExpand event handler back in after the update just in case it's getting lost somewhere, but this doesn't seem to work.

Any ideas what I'm doing wrong?

Thanks,
Courtney

Here's my ajax request code

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] values = e.Argument.Split(new[] { "|" }, 2, StringSplitOptions.None);

string nodeId = values[0];

string nodeText = values[1];

foreach (RadTreeNode node in GroupTree.Nodes)

{

if (UpdateNode(node, nodeId, nodeText))

break;

}

GroupTree.NodeExpand += (GroupTreeOnNodeExpand);

}

private static bool UpdateNode(RadTreeNode node, string nodeId, string nodeText)

{

if (node.Attributes["id"] == nodeId)

{

node.Text = nodeText;

return true;

}

foreach (RadTreeNode childNode in node.Nodes)

{

if (UpdateNode(childNode, nodeId, nodeText))

return true;

}

return false;

}

Treeview item has a problem in Download File

Hello,
Actually, I have some problem with the Treeview item in particular onClientContextMenuItemClicking as shown below:



function

onClientContextMenuItemClicking(sender, args) 

{

var menuItem = args.get_menuItem();

var node = args.get_node();

menuItem.get_menu().hide();

switch (menuItem.get_value()) {

case "SaveAs":

Xlate.Web.Translation.service.ResourceFilesService.ExportResourceFile('108', PassServiceHandler, FailServiceHandler);

break;

}

Save As menu item is supposed to save resx file [RESOURCE FILE in DOTNET]; it calls a webs service to get the file from the DB, and Download the file, but the below code didn't work out in this case, but when i tried it out without Ajax or Telerick controls, I could work it out:

[WebMethod()]

public void ExportResourceFile(string fileId)

{

List<ISearchResult> searchResults;

SearchCriteria searchCriteria;

try

{

searchCriteria = new SearchCriteria();

searchCriteria.ResourceFileID = int.Parse(fileId);

searchCriteria.SearchOption = SearchType.ResxKey;

ResourceFile resourceFile = ResxFileManager.CreateResourceFile(searchCriteria);

MemoryStream memoryStream = new MemoryStream();

memoryStream = Manager.GenerateResxSourceCode(resourceFile);

memoryStream.Position = 0;

DownloadFile(memoryStream,resourceFile.Name);

}

catch (Exception ex)

{

// set exception message

string errorMessage = String.Format("Failed to export resource fileid ={0}, error:{1}", fileId ,ex.Message);

// trace call

TraceUtil.Write("ResourceFilesService::ExportResourceFile", "Exception occured [{0}]", errorMessage);

// publish and rethrow the exception

BusinessException businessExc = new BusinessException(errorMessage, ex);

throw (businessExc);

}

private void DownloadFile(MemoryStream memoryStream,string fileName)

{

byte[] byteArray = memoryStream.ToArray();

memoryStream.Flush();

memoryStream.Close();

HttpContext.Current.Response.Clear();

HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=test.resx");

HttpContext.Current.Response.AddHeader("Content-Length", byteArray.Length.ToString());

HttpContext.Current.Response.ContentType = "application/octet-stream";

HttpContext.Current.Response.BinaryWrite(byteArray);

}
