Hi

I need to modify some data before the export so the pdf file will contain the updated data.

I tried to go over all the items of the MasterTableView and update the Text property of cell (gridView1.MasterTableView.Items[i]["columnNAme"].Text).

It did not worked.

Is there any way to do it ?

Thanks a lot

Applying the contentfilters on the server

As I understand the RadEditor control, there are a number of client-side javascript content Filters that can convert the entered text to valid XHTML.

Is this functionality also exposed on the server in managed code? Are there any server-side methods of the RadEditor that will let me do the conversion to XHTML on the server in C#?

Thanks for the help.

childNodes is Null or not a object...

Hey guys,

i have a roblem with the Treeview (but only in IE 7.0, Firefox works perfect).

If i put my mousecursor over the Treeview (and only then) an popup-error occures (without clicking).

It says:
Runtimeerror (...) Error: 'childNodes' is null or not a object.

If i look up in debug-mode it shows this:
(file: http://localhost/[projectname]/ScriptResource.axd)

    
            getChildrenByTagName:function(_c6,_c7){ 
        
            var _c8=new Array(); 
        
            var _c9=_c6.childNodes; <-- THIS IS HIGHLIGHTED 
        
            if($telerik.isIE){ 
        
            _c9=_c6.children; 
        
            }

Hope this might help you by finding an answer for my problem.

Any ideas? :)

p.s. I´m on (2008, 3, 1314, 35)

RadComboBox AutomaticLoadOnDemand is not working well with RadScheduler

Hi

When i use the RadComboBox's new feature of AutomaticLoadOnDemand inside RadScheduler's AdvancedForm.ascx i get the entire list instead of the "ItemPerRequest" number of 10 items.
It happends when the appointment Modal Dialog first pops up. when i choose an item or change the text for the first time, the AutomaticLoadOnDemand starts working properly but it takes lots of time because the list is too long at the begining
This code works perfectly on a normal aspx page.

    
            <asp:Panel runat="server" ID="AdvancedControlsPanel" CssClass="rsAdvMoreControls">  
        
                                <telerik:RadComboBox ID="rcb_patient" runat="server" CssClass="rsAdvResourceValue" 
        
                                    DataTextField="FullName" MarkFirstMatch="true" ShowDropDownOnTextboxClick="true" 
        
                                    ShowWhileLoading="true" DataValueField="PatID" EnableVirtualScrolling="true" 
        
                                    AllowCustomText="true" ShowMoreResultsBox="true" ItemsPerRequest="10" 
        
                                    LoadingMessage="loading..." EnableAutomaticLoadOnDemand="true" DataSourceID="sds_patients">  
        
                                </telerik:RadComboBox>

I'll appreciate any help.

Problem with comobox inside the ModalPopupExtender

I have the following code in the ModalPopup Panel. The problem is that I can see checkbox but no item on the side. If I remove the checkbox control then the items are visible. Is it a bug or do I have to include anything else in my code.

<asp:Panel ID="pn1" runat="server" CssClass="popup" Width="1200px" Style="display: none;"> <div class="body"><telerik:RadComboBox runat="server" ID="RadComboBox1" ZIndex="10000000" HighlightTemplatedItems="true">

<Items>

<telerik:RadComboBoxItem Text="One" Value="One" />

<telerik:RadComboBoxItem Text="Two" Value="Two" />

<telerik:RadComboBoxItem Text="Three" Value="Three" />

</Items>

<asp:CheckBox runat="server" ID="CheckBox" onclick="stopPropagation(event);" Text="" />

<%

# DataBinder.Eval(Container, "Text") %> </ItemTemplate> </telerik:RadComboBox> </div> </asp:Panel>

Thanks.

Set value of DataRowView

Hey Everyone,

I have hit a hard spot here.....I have no idea why this isn't working.

Code

    
            DataRowView dataItem = (DataRowView)commandEventArgs.Item.DataItem; 
        
            int _value= Convert.ToInt32(dataItem.Row["valueToRetrieve"]); 
        
            dataItem.Row[NUMBER] = GetDisplay(value);

NOTE: I have change some variable names for organizational purposes......

I don't know why this isn't working. It has worked for me in the past. Am i not calling a method I need to call. I know the GetDisplay() returns the right value. However, this isn't being displayed when the screen comes back up.

Any thoughts....

Thanks,

-zd

Slow pageload / ajax refresh

Hi,

I have a page wich contains left a radgrid with about 750 records (no paging) and right a formview.
The formview is databound on the radgrid, so when you select a row in the radgrid the formview refreshes with the selected record.

Pretty basic so far.

Now when i initialy load the page it takes about 3 seconds for everything to load.
Then, without the ajax it takes about 3 seconds for page to reload after i select a row in the radgrid. As you expect the whole page is reloaded. Something we dont want.

Now i added an Ajax manager in the hope i could cut down on this load time. I set the ajaxmanager so that for request on the radgrid it should only refresh the formview.
But this seems to make the application run slower! It now takes about 5 to 10 seconds for the formview to refresh.
What did i do wrong?

Anybody an idea,

Regards,
Jelte

[Solved] PageRequestManagerServerErrorException

Hi all,

I wonder if I am doing something "wrong" here...

I have a relatively simple form with one RadAjaxPanel, a few rad or ASP controls all within the panel and a button.
I saw the warnings about RadAjaxManager and RadAjaxPanel but there is no RadAjaxManager on my page.

When I press the button a first time, it goes to the server (Ajax request) to fetch some more information and then ask confirmation from the end user via some javascript injected with

RadAjaxPanel1.ResponseScripts.Add("AskConfirmation();");

The user gets correctly a radprompt dialog.
When he presses "OK", I set a hiddenfield to "1" and fires the click() method on the same button.

However, from that point on, no more request seems to work and I get the error

Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

I tried to debug on the server side but I can't hit any breakpoint even break all does not work.

Am I doing something drastically wrong by firing a button from within an injected javascript?

Many thanks

Eric
