Hi,

I would like to implement a Editor. I have got a treeview with the structure of my application. When clicking on a node (actually a node is a page of my application) the content must be shown in the editor to give the possiblity to the user to change its content.

I need to know how to do that step, when clicking on a node to charge the content of that page into the editor.

Do you know how to this?any nice example?

Thank you in advance.

[Solved] ClientOperation One node changes but multiple ClientOperation objects

Hi,

Before I log a support ticket maybe someone can put my mind at rest.

I am updating my tree on the client and then doing a postback to process the changes. It all works but I am seeing what I think is odd / could be a bug. I am iterating over the ClientOperation objects as recommended but I am only updating one node per postback.

    
             foreach (ClientOperation<RadTreeNode> operation in rtvMenu.ClientChanges)

On the updated node I am altering multiple propeties - 3 in total (text / value and adding an attribute). I assumed that I would only have one ClientOperation object containing one node object but I get three and I examined each node in debugging and they are all the same with the updated values. I did a test with updating only one property and boom - one object. This doesn't make sense - Why send 3 objects when they are all on the same node, I am hitting the db 3 times with the same information this way. It would make sense if there was a flag on each object saying with propropery was changed but as far as i can see there isn't one. So is this a bug or is there some reason by design it is doing this?

Thanks,

Leon.

PS Subscription up in 30 days and renewing for another year is a no-brainer - Telerik tools make me look good ;)

RadGrid losing track of current Edit Item after insert operation on DataSource

I have a RadGrid bound to a LinqDataSource. The grid has auto generated Edit and Delete columns. It displays a simple table without any hierarchical organization.

I am taking the following steps.
1. Populate a RadGrid using a LinqDataSource
2. Click Edit on the last row of the grid
3. From another control on the page, update the linqdatasource and call rebind on the grid
4. The grid loses track of the current editing item, and opens a different item in edit mode

Please help.

Style Builder - Setting Background Color

The color picker for setting background color in the style builder is empty. The others, for font and border colors, are fine.

I fixed this by adding the following lines to StyleBuilder.ascx at line 353 (in the 'clientInit' function):

$find("backgroundColor").set_items(this._clientParameters.Colors);
$find("backgroundColor").set_color("");

Error in Office2007 skin

I've just moved my app to Q1 2009 and noticed that the window skin has a slight anomaly.

Have a look at this image and you'll see that there is something odd along the bottom centre of this window, which, if it makes any difference, was opened with Modal=true.

FileUpload in grid template with ajaxpanel

Hi,
I have a regular asp:FileUpload in a template in a grid.
It works fine to upload if ajax is not enabled but with ajax it wont work.
Javascript errormessage:
Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
I have looked at your demo and to use onrequeststart on the panel,
http://demos.telerik.com/aspnet-ajax/ajax/examples/common/fileupload/defaultcs.aspx
but I cant figure out what's wrong!

    
            <script type="text/javascript"> 
        
                    function OnRequestStart(target, arguments) { 
        
                        if (document.getElementById("FileUpload2") != null) { 
        
                            var fileUpload = document.getElementById("FileUpload2"); 
        
                            if (fileUpload.value != "") { 
        
                                arguments.set_enableAjax(false); 
        
                            } 
        
                        } 
        
                    } 
        
            </script> 
        
            <telerik:RadAjaxPanel runat="server" ID="radAjaxPanel" Width="100%" LoadingPanelID="radAjaxLoadingPanel" ClientEvents-OnRequestStart="OnRequestStart"> 
        
                 <telerik:RadGrid ID="RadGrid1" 
        
                 ... 
        
                 <EditFormSettings EditFormType="Template"> 
        
                       <FormTemplate> 
        
                            <input id="FileUpload2" type="file" runat="server" class="fileUpload" /> 
        
                            <asp:Button ID="buttonUploadFile" Text="Ladda upp" runat="server" ValidationGroup="validationGroupFile" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' CommandArgument="File" />
