Hello,

I created a upload system for my site and I need to provide custome error handling on the client side. I saw an old forum post that says the RadUpload controls do not have the ability to check for timeout or file size limitations. I have the proper code in my web.config file but I need to be able to display a custom error message when one of those events happens. Is that any update on this matter? Is it now possible to create custom error handling for these issues?

Saving Page with TabStrip and Multipages takes a very long time

I pasted the page below. Any kinds of modifications to this page takes one or two minutes to save in Visual Studio 2008 (sp1). Other types of controls do no take so long (for instance, i played around with panelbars and other types of controls). I also have Ankh installed...a Subversion source control provider plugin for Visual Studio. Could that be the culprit? Any other reports of such slowness in saving pages?

Radgrid as null

Hi,

When i try to bind my grid setting the datasource to a datattable in a radgrid, I'm getting radgrid as null and getting the message "object reference not set" I'm cuurently having some assembly problem . ( i already have posted in forums telerik[a] cannot be cast into telerik[b]). Is it because of that?

Usually i never get radgrid as null when i try to set datasource.
Any help would be really appreciated.

Thanks,
ZR

Year view

Hi,

I have a calendar with 4 columns and 3 rows to display a whole year.
Setting focused date to the 1st Jan of the current year brings what I need to show.
A year starting 1.1 - and ending 31st Dez.
My problem - if I use fastnavigation and choose (for an example) Today (or a month) I get a view which shows
12 months beginning with the selected one.
My approach - it should display the year (of the selected date) but again 1st Jan to 31st Dez,
I tried to handle DefaultViewChanged - but the code does nothing more then setting the fast navigation properties.
So what I get is a correct (showing jan to dec) fast navigation.
My calendar still displays 12 calendars starting with the selected month instead of Jan what I need.
Here my code

    
            protected void rcYear_DefaultViewChanged(object sender, Telerik.Web.UI.Calendar.DefaultViewChangedEventArgs e) {  
        
                DateTime dtSel= e.NewView.ViewStartDate;  
        
                e.NewView.ViewStartDate = new DateTime(dtSel.Year, 1, 1);  
        
                e.NewView.ViewEndDate = new DateTime(dtSel.Year, 12, 31);  
        
                e.NewView.ParentCalendar.CalendarView.ViewStartDate=new DateTime(dtSel.Year, 1, 1);  
        
                e.NewView.ParentCalendar.CalendarView.ViewEndDate = new DateTime(dtSel.Year, 12, 31);  
        
                e.NewView.ParentCalendar.FocusedDate = new DateTime(dtSel.Year, 1, 1);  
        
                rcYear.FocusedDate = new DateTime(dtSel.Year, 1, 1);  
        
            }

I know this a bit too much - but I tried to set everything I could find :)

Regards

Manfred

RadGrid Export to Excel After Rebinding

I have a RADGrid that is databound upon page load. I have a button that initiates the Export to ExcelML.

The problem I have is this. When I rebind the RADGrid so that it contains new data, when I click the Export to ExcelML button, the data that is exported is the data that was originally bound when the page first loaded. In essence, the RADGrid is displaying new information but the export is still exporting the old information.

I am using a sqldatasource to bind the RADGrid.

Any ideas?

Default Edit Mode for DetailTableView

How would someone put all items in a DetailTableView into edit mode when the parent is expanded?

I have already viewed the documentation outlining how to put everything into edit mode by default using the PreRender event. Not only does this put the DetailTableView items in edit mode, but also the MasterTableView (unwanted). In addition, this causes the paging mechanism to become useless as the first page is always displayed.

In another article, a method of adding the indexes to the EditIndexes collection is covered. I do not see how you can add the indexes of the DetailTableView items to this collection.

Any help would be greatly appreciated. The current mechanism which requires users to click an Edit button next to each row and then update is "cumbersome" according to my users. Providing the ability to edit in batch (updating in batch is covered in one of your articles) would be priceless.

Regards,
Jake

[Solved] Export from Ajaxified grid in UserControl

Hi,

I am trying to achieve the functionality shown in
http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

I am able to make my tab and multipage work as shown in the above example. I also want to have the export option for the grids which load from the usercontrol. Can you please suggest what can I do in this scenario. For Ajaxified grid, we have to cancel the AJAX as suggested in the examples I got from the following link:
http://www.telerik.com/community/code-library/aspnet-ajax/general/export-radgrid-content-to-excel-word-csv-pdf-with-ajax-enabled.aspx

How can I refer to the button control defined in the usercontrol page which starts the export process to cancel the AJAX for that process? AJAX Manager is ajaxifying the whole tab in this load on demand example, so can I refer to the button in usercontrol ?

<

telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">

<telerik:AjaxSetting AjaxControlID="RadTabStrip1">

<telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />

<telerik:AjaxUpdatedControl ControlID="RadMultiPage1" LoadingPanelID="LoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadMultiPage1">

<telerik:AjaxUpdatedControl ControlID="RadMultiPage1" LoadingPanelID="LoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</

telerik:RadAjaxManager>

Can you please suggest what can I do in this scenario?

Thanks.

Dynamically added usercontrols not rendered like they should

Hi there

I have a usercontrol called ReportContainer.

This is the markup.

                    <telerik:RadScriptManager ID="scriptManager" runat="server" />         
            <telerik:RadTabStrip ID="tsReport" runat="server"          
                ontabcreated="tsReport_TabCreated" >            
            </telerik:RadTabStrip>         
                     

And this is the codebehind.

                     protected void Page_Load(object sender, EventArgs e)         
                    {         
                        if (!Page.IsPostBack)         
                        {         
                            LoadTabs();         
                        }         
                    }         
                     
                     
                    private void LoadTabs()         
                    {         
                        RadTab radTabGeneral = new RadTab("General");                    
                        tsReport.Tabs.Add(radTabGeneral);         
                                
                     
                    }         
                     
                    protected void tsReport_TabCreated(object sender, RadTabStripEventArgs e)         
                    {         
                         TabGeneral tabGeneral = (TabGeneral)LoadControl(@"~\Report\Controls\Tabs\TabGeneral.ascx");         
                         e.Tab.Controls.Add(tabGeneral);         
                    }         

The markup from the UserControl I try to add is this.
