I am new to the Telerik controls but I have been testing them out for a couple of weeks on a proof of concept project. I am really liking the flexibility and power of this control set. But there is a bit of a learning curve.
I'm hving an issue with canceling the sort event on the grid. I basically want to trap the sort command and stop the postback but have the header images reflect the sort direction and grap the sort expression. I am doing this all client side so I will call a web service to get the data and rebind. I found an example on how to cancel a command but for some reason the postback is still happening. I am using the demo version of the Ajax/UI control version 2009.02.0701.35. Bellow is my code.

The Grid

    
                <telerik:RadGrid ID="RadGrid1" runat="server" AllowSorting="True" GridLines="None" 
        
                    Skin="Forest" AutoGenerateColumns="False" GroupingEnabled="False" ShowStatusBar="True" 
        
                    Width="100%" Height="300px" EnableViewState="False">  
        
                    <MasterTableView ClientDataKeyNames="bl_id,fl_id,rm_id" TableLayout="Fixed" EnableViewState="False" 
        
                        AllowNaturalSort="True" AllowFilteringByColumn="false">

                            </telerik:GridBoundColumn> 
        
                        </Columns> 
        
                    </MasterTableView> 
        
                    <ClientSettings> 
        
                        <DataBinding CountPropertyName="" MaximumRowsParameterName=""   
        
                            StartRowIndexParameterName="" SelectMethod="GetRoomList"   
        
                            Location="services/SjeccdSpaceWebService.asmx" FilterParameterName="filter"   
        
                            FilterParameterType="Linq" SortParameterName="sort" SortParameterType="Linq">  
        
                        </DataBinding> 
        
                        <Selecting EnableDragToSelectRows="False" AllowRowSelect="True" /> 
        
                        <ClientEvents OnCommand="CheckStuff" /> 
        
                        <Scrolling AllowScroll="True" UseStaticHeaders="True" EnableVirtualScrollPaging="false" /> 
        
                    </ClientSettings> 
        
                </telerik:RadGrid>

The script

    
            <script id="sample" language="javascript" type="text/javascript">  
        
                function CheckStuff(sender, args) {  
        
                     //cancel the default command to prevent postback/ajax request  
        
                    //var sortExpressions = sender.get_masterTableView().get_sortExpressions();  
        
                    if (args.get_commandName() == 'Sort'){  
        
                        args.set_cancel(true);  
        
                        //get data and update grid;  
        
                    } 
        
                    alert(args.get_cancel()); //+ sortExpressions.toString());  
        
                }  
        
            </script>

After I click the column header the sort command is trapped. I get a message box wiith 'true' and I select OK. Then the grid updates with the new sort. Does this have something to do with the data binding section of the grid control? I have about 8 hours into this and I have tried a number of diffent options. I am just stuck. Any help or best practices would be appreciated.

Thanks,
Craig

Hi,

I have a radeditor control inside a div with style="display:none" (because i use a jquery dialog plugin - jQuery UI 1.8.9 - to render that div in a popup) and when i show the div, the control not allow the text insert.

This behavior does not always occur, but when occurs the console of firebug shows the following error:

_b2 is null

addExternalHandler()Script...e6098e2 (line 697)

_b2 = null

_b3 = "keydown"

_b4 = function()

_PopupController()Script...e6098e2 (line 3456)

createEditorPopupController()Script...e6098e2 (line 3547)

[Break On This Error] if(_b2.addEventListener){

Other informations:
- Controls version: Telerik.Web.UI, Version=2009.1.527.20

Find columns!

Hello,

I was working with the Q2 version of AJAX and every thing was fine.

And yesterday I have updated my version to the Q3. And one page of my website doesn't work anymore... I have a message saying:

Can't find the column [MyDevis.Montant].

So I came back to the Q2 version, and every thing work perfectly.

Do you have any ideas?

Thank You

Jean-Yves

Duplicates in SelfHierarchy RadGrid

I have a problem with RadGrid in "SelfHierarchyMode".

My settings in aspx:



<telerik:RadGrid runat="server" ID="rgArtikelSuche" AllowSorting="false" AllowFilteringByColumn="false"
    AutoGenerateColumns="false" AllowMultiRowSelection="true" Visible="false"  OnNeedDataSource="rgArtikelSuche_NeedDataSource" >
    <ClientSettings AllowKeyboardNavigation="true" AllowExpandCollapse="true">
        <Selecting AllowRowSelect="true" UseClientSelectColumnOnly="true"  />
    </ClientSettings>
    <MasterTableView  HierarchyLoadMode="Client" HierarchyDefaultExpanded="true"
     DataKeyNames="Key, GroupKey">
        <SelfHierarchySettings ParentKeyName="Parent" KeyName="GroupKey" />
    </MasterTableView>
</telerik:RadGrid>

My datasource look like:

Key    GroupKey    Parent    Description
1        A1                null         A1
2        B1                A1          B1
3        B2                A1          B2
4        A2                null         A2
5        B3                A2          B3

The Elements B1, B2 and B3 are shown on ClientSide under their parent Element AND direct under the root, so they were shown twice.

WHY????

Upgraded 2011.2 to 2011.3 and broken

Not sure what the issue is, there are no js errors, no code errors, everything compiles.

One of the tabs does not work after the upgrade. Once I go to that tab, then I can't go to any other tab. Again, no errors of any kind. All we did was upgrade.

Rad combobox doesn't update data after edit

I am using RadCombo box for my Asp.net Application.

On the page load data is being bound to the combobox. Now there is an option to edit the data in the Combo box by clicking on a link that is beside the combobox which brings a popup window where we edit the data and Update. On Updating the value the popup window is closed thereby refreshing the Combobox (client side).

For that i am using the following code.

cboCases.clearItems();

cboCases.requestItems(sel, false); //Here value of sel is the selected index’s value.

After the request_Items fires the sever side event is called to bind the combobox.

The server side code is

cboCases.DataSource = listObjects;

cboCases.DataBind();

cboCases.SelectedIndex = int.Parse(sel); //sel is the values passed from Request_Items

My Issue is that even though we are setting the selected index value, what is being reflected in the UI is the same old value.But once we change the index of the combobox manually from the UI the data is the updated value.
