Questions on UI for ASP.NET AJAX Forum

I currently have on my page a RadSplitter control. On the left side of the splitter, I have a RadTreeView, and on the right side I have a RadGrid. I've added the RadAjaxManager to update the RadGrid when a folder is clicked on in the RadTreeView. The problem I'm getting is that I keep getting a Javascript popup error everyonce in a while when I go to click on a folder in the tree view to load up information into the RadGrid. The RadGrid appears to be loading, but then stops once this error pops up. Now if I go and click on another folder after I get this Javascript popup error, everything works fine.

Like I said, I only get this error every once in a while. I've looked at the other posts in this forum and tried all different things. None of them really solved my issue.

Here is what I'm getting in the Javascript error popup.

Sys.WebForms.PageRequestManagerPraserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Decimal Places in Pie Chart Values

Hello,

I'm wondering if there is a way to add decimal places in the values that are displayed with the RadChart.

Instead of having 0% I would for example like to display 0.48%

Thanks,

Updating RadGrid Groups Client Side

Hi there,

I have a question about radGrid clien-side databinding, using WebServices.
In my RadGrid, I'm grouping datas function of a column. When I update dynamically(client-side) my datagrid, grouping doesn't seem to work well:
independently of the number of elements which belong to the group, this one have always have the same number of items.
Here, I'm grouping fonction of MembreConvers wich is a string.

    
                    <MasterTableView ClientDataKeyNames="IdContact" GroupLoadMode="Client"   
        
                                    NoMasterRecordsText="" ShowHeadersWhenNoRecords="true" Width="100%">  
        
                                    <GroupByExpressions> 
        
                                        <telerik:GridGroupByExpression> 
        
                                            <SelectFields> 
        
                                                <telerik:GridGroupByField FieldAlias="MembreConvers" FieldName="MembreConvers"   
        
                                                    HeaderText="Participe" /> 
        
                                            </SelectFields> 
        
                                            <GroupByFields> 
        
                                                <telerik:GridGroupByField FieldName="MembreConvers" /> 
        
                                            </GroupByFields> 
        
                                        </telerik:GridGroupByExpression> 
        
                                    </GroupByExpressions> 
        
                        <Columns> 
        
                            <telerik:GridMaskedColumn DataField="MembreConvers"   
        
                                            SortExpression="MembreConvers">  
        
                                        </telerik:GridMaskedColumn> 
        
            <!-- Continue -->

And I'm updating it with that javascript, client-side. I need to pass args to my WebMethod, so I'm not using Telerik's codeLess method.

    
            //Called When WebService GetContactListForConversation return              
        
            function SucceededCallbackGetParticipants(result, eventArgs) {  
        
                            //Conversation ID - and so window - is in eventArgs.  
        
                            //It allows us to get current conversation's radWindow  
        
                            var radWindowManager = GetRadWindowManager();  
        
                            var window_ = radWindowManager.getWindowById(eventArgs);  
        
                            if (window_ != null) {  
        
                                  //Get the frame  
        
                                var frame = window_.get_contentFrame();  
        
                                  //Get the window  
        
                                var windowContent_ = frame.contentWindow;  
        
                                var radGrid = windowContent_.$find("RadGridContacts");  
        
                                //Get Master TableView  
        
                                var tableView = radGrid.get_masterTableView();  
        
                                   //Set dataSource and DataBind  
        
                                tableView.set_dataSource(result);  
        
                                tableView.dataBind();  
        
                                //Using setTimeout instead of setInterval(firefox compatible)  
        
                                setTimeout(function() { GetParticipantsForConversation(eventArgs) }, timeout);  
        
                            }

WebService returns List<Contact>:

    
                public class Contact  
        
                {  
        
                    public string NomPrenom { get; set; }  
        
                    public int IdContact { get; set; }  
        
                    public string EnLigne { get; set; }  
        
                    public string MembreConvers { get; set; }  
        
                 // Continue here ....  
        
            }

On page load, server-side, in "RadGridContacts_NeedDataSource" method I create MasterTableView like that:

    
            //Test                    
        
              List<Contact> contactsList = new List<Contact>();  
        
                           //there will be 2 groups : "Oui" and "Non".  
        
                          contactsList.Add(new Contact("", 0, true, "Oui"));  
        
                          contactsList.Add(new Contact("", 0, true, "Non"));   RadGridContacts.MasterTableView.DataSource = contactsList;  
        
            /*And when I'm updating Client-side, group "Oui" and "Non" are limited to 1 item each. How can I fill them client-side?*/

Is there an easy trick to update these groups client-side?

Thanks a lot,

Alex.

Bug editing an recurring appointment

Hi

I think i've come across a bug in the advanced edit form using webservice population. A recurring appointment is moved in time when you doubleclick any occurence but the first one and select "edit series".

This can be reproduced in your online demo of webservice data population.

Steps to reproduce:
1: Create a daily recurring event. Starting Sep. 1st 2009 with 10 recurrences
2: Doubleclick Sep. 5th 2009 and select "Edit series"
3: Open advanced form

The advanced form has start date set to Sep 5th with 10 recurrences. By accepting the entire series is moved 5 days ahead.
Your other demos behave as expected and keep the original start date.

Hope you can fix this and maybe even provide an immidiate workaround.

Context Menu - Javascript GetDataKeyName of Parent

Hello all. I am trying to get a datakeyname from the parent
of a child table when the Context Menu is displayed. I am
having a difficult time trying to figure this out. Any ideas?
Thanks.

    
            // Abbreviated function for ease of reading  
        
            function ShowContext(sender,args){  
        
            var menu = $find("GridContextMenu");  
        
            var selectedindex = args.get_itemIndexHierarchical();  
        
            //Not sure about below  
        
            var parentindex = sender.get_parentView().getDataKeyNames("EventId");  
        
            menu.show(args.get_domEvent());

Get column value from parent table in a hierarchical grid using javascript

I have a hierarchical grid - the Master table and a details table. When the user expands a row in the parent table the details table is loaded. The details table has an Add New Record button. When this is pressed, I need to obtain the value of some column in the parent row that was expanded. This must be done on the client-side using javascript. Note: the parent row is not selected, it's just expanded, so I cannot rely upon obtaining the selected row. I could not find any API method for the client side on how to obtain a value in the parent row. Any suggestions?

Thanks
Johann
