Hello,

I have recently upgraded from Q3 2011 to Q3 2012 and now my Spin Buttons on the numeric text box appears on the bottom of the control rather than to the side (attached image). Can anyone give me a suggestion on what is causing this.

Thanks

Multi Series Bar Chart Data points slide to left

I have a bar chart with multiple series.

   chartResults.DataManager.ValuesYColumns = "fValue"
   chartResults.DataManager.ValuesXColumn = "iDate"
   chartResults.DataGroupColumn = "sType"
   chartResults.PlotArea.XAxis.Appearance.ValueFormat = Styles.ChartValueFormat.ShortDate
   chartResults.DataSource = dt
   chartResults.DataBind()

   chartResults.PlotArea.XAxis.AutoScale = True
   chartResults.PlotArea.XAxis.IsZeroBased = False
   chartResults.PlotArea.YAxis.IsZeroBased = True
   chartResults.PlotArea.XAxis.Appearance.Visible = Styles.ChartAxisVisibility.True

When one series exists, the rightmost point lies to the right (correctly) of XLabel 10/23/2012. When a second series is added, the rightmost point moves to the left of 10/23/2012. This is incorrect, and does not reflect the accuracy of the first series.

Can someone offer any advice, or workaround to get the points to stay on their correct x-axis point?
Any help or advice is greatly appreciated! TIA!

RadUpload does not upload file

We have placed a RadUpload control in a DotNetNuke module and selected the file. We also have an asp:button on the control set to Submit. When we press the button, the RadUpload.UploadedFiles.Count is always ZERO and the file never gets uploaded. The page is being refreshed by the submit button during the postback.

Here is the GUI code:

<asp:Panel ID="pnlFileUpload" runat="server">

Allowed File Extensions are: .jpg, .gif, .bmp, .png

<telerik:RadUpload id="RadUpload1" Runat="server" AllowedFileExtensions="jpg, gif, bmp, png" TargetFolder="~\Portals\0\ClientLogos" MaxFileInputsCount="1" >

</telerik:RadUpload>

<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />

</asp:Panel>

the btnUpload button is set to UseSubmitBehavior=True. What are we missing? DotNetNuke version 5.04.02 community.

Calling Javascript after postback

When a user clicks on the "Save" button, I want to write a message that says "Saved at [current time]" (like Gmail does when saving a draft). In order to get the current time I was going to use javascript. How do I go about calling the Javascript to get the time and displaying it in my label?

Some things to note:

I am using ASP.Net 2.0 and the latest build of Promethius
I am using a Master Page that has the AjaxManager and my other pages and usercontrols are all using the AjaxManagerProxy controls
I only want this message to be set when a certain button is clicked, not on every ajax request.

Any help would be appreciated.

Error: Could not find a part of the path...

I have developped some aspx page with a RadUpload Control.
After setting everything on my dev server, it worked fine
but when uploading it on the prod server, I received the following message after clicking the "Submit" button;

    
            Server Error in Application.     
        
            Could not find a part of the path 'F:\Applications\Upload\Hours\test.txt'.     
        
            Exception Details: System.IO.DirectoryNotFoundException: ...

My question is; what are the access right requirements for RadUpload to work?
As in an intranet environment, we setted up a generic account for this IIS application with Full rights on this folder but I suspect maybe something with the rights, any hint?

Regards,
David

RadUpload and RadProgress last file does not appear to finish.

Ok,

Been playing with Telerik for a little while, really like it, thinking about purchase but I hit a wall.

I have a content page that has NO update panels just the rad controls and a couple of datalists to display the results...works on my machine and on the server but on the server when we upload a large amount of files it uploads just fine BUT the progress control never finishes on the users screen but the upload does work...I cannot replicate on my dev machine so i cant figure the problem...The control works perfectly on two or three files and its not specific on how many files it takes to fail...

Does this set of controls have issues on GoDaddy?

Code Below,

Thanks!

problem with upload

hi,

I have a radUpload control named "radUp".

When I click on the submit button I call "uploadFile" :
"renameFile" is the new name written by the user on a textbox.
I want to save the file with this name, but I have 2 files on my Directory "Documents" after click: the renamed file and the other .... I want only the renamed file ... what's wrong?

protected void uploadFile()

{

if (radUp.UploadedFiles.Count > 0)

{

foreach (UploadedFile file in radUp.UploadedFiles)

{

String targetFolder = Server.MapPath("~/Documents");

file.SaveAs(Path.Combine(targetFolder, renameFile.Text));

}

Thanks
