This sounded like such a simple request but I simply can't figure it out.

I want to prevent the user from selecting certain file types (I'm trying to implement a blacklist type of validation rather than the whitelist method that the telerik control comes with out-of-the-box).

OK, so there's no set_cancel() method for OnClientFileSelected. A shame, but moving on.

I though, OK, if they select an invalid file type, I'll just remove it, so came up with this ....

var fileExtensionBlacklist = "<%=DisallowedFileTypes %>";

function OnClientFileSelected(sender, e)

{

if("<%=UseBlacklist %>" == "True")

{

var selectedFileName = e.get_fileName();

var selectedExtension = selectedFileName.split(".").pop();

if (fileExtensionBlacklist != "" && fileExtensionBlacklist.indexOf(selectedExtension) > -1)

{

try { $find("<%=RadAsyncUpload1.ClientID %>").deleteFileInputAt(e.get_rowIndex()); } catch (ex) { }

}

function OnClientFileUploadFailed(sender, e)

{

e.set_handled(true);

}

This doesn't work, the attempt to delete the file input generates an error reporting "HtmlPage_NotEnabled" in a line of javascript that calls Content.Page.MarshalUploads(). This appears to be something to do with Silverlight, but I can't stop it from happening.

Working to a deadline, I moved on.

So, I thought, "OK, if I can't stop 'em selecting these files, I can at least, stop 'em from being uploaded".

So, I modified the code to this ...

function OnClientFileUploading(sender, e)

{

if("<%=UseBlacklist %>" == "True")

{

var selectedFileName = e.get_fileName();

var selectedExtension = selectedFileName.split(".").pop();

if (fileExtensionBlacklist != "" && fileExtensionBlacklist.indexOf(selectedExtension) > -1)

{

e.set_cancel(true);

}

Tried that and Yay! the file is mared red as a failed upload!

Then I click on the button on my page to actually do the postback and process the uploaded files. Get what I find in my server-side list of uploaded files, yep. The file that I had set cancel on. What's more it shows it IsValid as true.

Is this God's punishment for me working on a Sunday? If it is, he's picking on the wrong bloke, I have no choice; he should go smite the guy who said I had to.

If anyone can offer any suggestions as to what I'm doing wrong, I'd love to hear 'em.

Custom Skin Using Sprites

I am attempting to create a custom skin for all of the ASP.NET AJAX Controls so that all the controls have a unified look and feel that matches the rest of my site. I have found all of the sprite.gif files inside of C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX\Skins, but it seems like a tedious task to take all of these and edit them to fit my color scheme. I have tried on multiple occasions to use the Visual Style Builder to create a custom skin, these endeavors have always ended horribly, that tool simply does not work. Then I found the .psd files located at telerik.com/skins, these seemed to be exactly what I was looking for, I could restyle the entire control at one time, then theoretically slice it up into the sprite.gif files that would work with the css for the control. But this is where I get stuck, once you have the .psd altered the way you want it to look, how then do you convert/slice those into the sprite files that the css will know how to use?

Thanks

Set the selectedfilterfunction on Enter key press

Hi,

I have a RadGrid with filtering of columns enabled. I have set the CurrentFilterFunction so that that filter function gets selected as default instead of the 'NoFilter'. I would like to use the Enter key to apply the selected filter function. Now when I press Enter key the filter function list open up instead of getting selected.

Thanks,
Raji

Second level group always expanding

Hello!

Setup:

2 levels of grouping using the GroupByExpressions collection of the MasterTableView within the declarative portion of a page
MasterTableView.GroupLoadMode set to “Client”
MasterTableView.GroupsDefaultExpanded set to “false”

When I expand any of the top/1st level groups, I am expecting that the child/2nd level groups are shown expanded/collapsed based on their Expanded property. Instead what happens is that the child/2nd level groups are all shown as expanded.

Is this behavior expected or is there a fix/workaround that you can provide?

Thanks in advance,

Brent

Tooltip TextBox values not updated

I created a Tooltip based on the "Load On Demand" example. In the tooltip I have an asp:Label and an asp:TextBox. The values for these fields can change each time the tooltip is displayed. When I initially display the tooltip, the label and textbox have the expected values. However, when the tooltip is displayed the next time and I set different values for the label and textbox, the label shows the new value, but the textbox contains the original value.

This behavior can be observed by making the following changes to Load On Demand example code:

In the ProductDetails.ascx, add the following row to the "Product Wrapper" table:

    
            <tr> 
        
                <td> 
        
                    <asp:TextBox ID="txtDT" runat="server" /> 
        
                    <asp:Label ID="lblDT" runat="server" /> 
        
                </td> 
        
            </tr>

In the ProductDetails.ascx.cs, add the following code to the ShowCurrentDetails() method:

    
            String dt = DateTime.Now.ToLongTimeString(); 
        
            txtDT.Text = dt; 
        
            lblDT.Text = dt;

The label's value is changes on each time the tooltip is displayed, but the textbox's value retains the original timestamp.

I also added the following code to the method UpdateToolTip(...) in Default.CS.aspx.cs, but it didn't help:

    
            panel.Update();

Any ideas on what I'm doing wrong?
