webservice & selectedValue

I am trying to use the WebService to populate my drop down.

Now, when I show the dropdown first time I need to show a selected item. What is the recommended way of doing that? because setting selectedValue does not have any effect because there is not data bound to it from server side!!

Thanks,
Piyush

Standard look on input?

Is it possible to obtain a standard look on the input control?

Mixing the control with e.g. standard dropdownlist looks somwhat odd - and forcing me to use the RadComboBox (even though it in my case isn't necessary)

(... and I guess vice-versa, is it possible to obtain standard look on the combobox?).

Showing Min, Max and Current Value

I can't seem to find a property that will display the min, max and current value. I feel I must have missed something! Is there really no way to show these numberic values?

I'd picture the min on the left of the slider, the max on the right, and the current value probably above.

Thanks,
Sarah

Update controls outside of RadGrid

Hello,

Is it possible to capture an Ajax callback from a rowclick, and then update a part of the web page completely outside of the Grid. I have a Dundas chart in a panel, and I need to capture the value in the selected row and then rebind the dundas chart using Ajax. I have tried using AjaxManager to get the RadGrid to update the ASP:PANEL the Dundas chart resides in, but the chart doesnt get redrawn - nor does a loading panel cover the dundas chart.

I know the event is being fired and captured as I have traced it.

Forgetting the Dundas piece...how would you update a control outside of the Grid without using the Literal control I have seen in the documentation?

Thanks

[Solved] How To: Add Upload Zip & Extract To File Browser Dialogs

I tried to get this included as a standard feature of the editor, but with no luck:

http://www.telerik.com/community/forums/thread/b311D-htbgg.aspx

So, I spent a few hours heeding the advice of the Telerik guys and extended their File Browser so that my users can do bulk uploads of files in a zipped file format.

I have posted a small project in the Code Library that demonstrates this in action, here:

http://www.telerik.com/community/code-library/submission/b311D-bdcktd.aspx

And, despite the heckling I'm sure to get, I still work in VB so the code posted here is in VB. Use www.codechanger.com to convert to C# if you need.

Some notes on my own logic used here. Since the user is allowed to upload a zip file we no longer know for sure what is contained in that file - it could be any combination of any kinds of files and / or directories. I decided that I liked the feature of the user being able to upload directories of files so the code allows for that. Essentially, this is the pseudocode:

1) Is the uploaded file a zip file? If yes, then goto step 2, otherwise, proceed as normal.
2) Don't save the zip file to disk, begin extraction in-memory
3) For each entry in the zip file, determine if it's a file or a directory
4) If it's a file, delete the file if it already exists. If it's a directory, create the directory.
5) Check that the file is a non-zip file that complies with the file types specified in the search patterns. If it is a valid file, save it to disk.
6) Check that all directories and sub-directories contain image files. If the directory is empty, delete it. This is because a directory in the zip file could have contained an invalid file - but the directory would have still be created.
7) Try to return the path of the last extracted file to the File Browser Dialog - this doesn't work if the File Browser needs to change a directory but it does work in all other cases.

For those who don't want to download the whole project from the code library and just want to copy/paste the needed code for their own project, here's how it's done.

Step 1: Download and add a reference to the SharpZipLib.dll for your website / project.

Step 2: Extend the built-in FileSystemContentProvider. The only method that needs to be overridden is the StoreFile method, but you'll also need to create a New(...) method. Add the following class to your App_Code folder. Note: to make the code smaller, I've removed all comments but hopefully it makes sense:

                  If IO.Directory.GetFiles(Dir).Count = 0 And IO.Directory.GetDirectories(Dir).Count = 0 Then 
        
                    IO.Directory.Delete(Dir)  
        
                  End If 
        
                Next 
        
              End Sub 
        
              Private Function IsValidFileTypeAfterUnZip(ByVal fileName As String) As Boolean 
        
                Dim strExt As String = Right(fileName, fileName.Length - fileName.LastIndexOf(".")).ToLower  
        
                If strExt = ".zip" Then 
        
                  Return False 
        
                Else 
        
                  For Each s As String In MyBase.SearchPatterns  
        
                    s = Right(s, s.Length - s.LastIndexOf(".")).ToLower  
        
                    If s = strExt Then Return True 
        
                  Next 
        
                End If 
        
                Return False 
        
              End Function 
        
            End Class

Step 3: Add the "*.zip" extension to the SearchPatterns of the Image/Document/Media/Etc Manager; which unfortunately also means you need to manually re-input all of the default file extensions. This is what it looks like for the ImageManager (Note: I haven't brought back all of the default extensions):

    
            <telerik:RadEditor runat="server" ID="RadEditor1" Skin="Default">  
        
              <ImageManager DeletePaths="~/Images/" SearchPatterns="*.gif,*.jpg,*.jpeg,*.jpe,*.tiff,*.tif,*.bmp,*.png,*.zip" UploadPaths="~/Images/" ViewPaths="~/Images/" /> 
        
            </telerik:RadEditor>

Step 4: Set the ContentProviderTypeName for the Image/Document/Media/Etc Manager that you want to enable zip files for:

    
            RadEditor1.ImageManager.ContentProviderTypeName = GetType(UnzipFileSystemContentProvider).AssemblyQualifiedName

Step 5: Make sure you add all the other necessary stuff required by the Editor in Q1 2008 and going forward, such as the HttpHandlers in the Web.config and the RadSpell dictionary in the App_Data folder.

Moving from one version of AJAX controls to another

When upgrading the 'classic' controls, I just installed 'em, removed the old references in my project and added them back pointing at the new version of the controls.

I've just done my first upgrade of AJAX controls (2007.3 to 2008.1) and did the same thing I'd do with the 'classic' controls. Whilst the project compiled OK when I tried to run it the system complained. Basically it was looking for the old version of the controls. I had a look in the web.config file and the <httphandlers> element included this ...

    
            <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2007.3.1425.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

I changed the line to read the correct version number and everything was OK.

The question is, is having to make this change manually normal, or is there something else I should have done to ensure that the project was correctly updated?
