I have problem to add RadDatePicker in control that control further add in RadDock dynamincally

Background:
I am trying to create a RadDock dynamically on an .aspx Page and further adding a Control(.acsx) in RadDock. The .acsx Control has a RadDatePicker, RadComboBox, asp:ImageButton controls etc in it. The .aspx page also contains a RadComboBox.

Issue:
In that Page, I need to repopulate the RadDock with Control when the RadDock moves from a RadDockZone to other RadDockZone .

I am try create this page with help of example that is published on the telerik site(Dynamically add Raddock)

I am getting some errors when I am trying to do so:

1.Sys.InvalidOperationException: Type Telerik.Web.UI.Orientation has already been registered.

2.Sys.InvalidOperationException: Type Telerik.Web.UI.RadComboBoxEventArgs has already been registered.

3.Sys.InvalidOperationException: Type Telerik.Web.UI.AttributeCollection has already been registered.

4.(missing : after property id) Sys.Application.add_init(function() {
$create(Telerik.Web.UI.RadCalendar, {"_DayRenderChangedDays":{},"_FormatInfoArray":[["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"],["Sun","Mon","Tue","Wed","Thu","Fri","Sat"],["January","February","March","April","May","June","July","August","September","October","November","December",],["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec",],"dddd, MMMM dd, yyyy h:mm:ss tt","dddd, MMMM dd, yyyy","h:mm:ss tt","MMMM dd","ddd, dd MMM yyyy HH\':\'mm\':\'ss \'GMT\'","M/d/yyyy","h:mm tt","yyyy\'-\'MM\'-\'dd\'T\'HH\':\'mm\':\'ss","yyyy\'-\'MM\'-\'dd HH\':\'mm\':\'ss\'Z\'","MMMM, yyyy","AM","PM","/",":",0],"_ViewRepeatableDays":{},"_ViewsHash":{ctl00_MainCntrl_RadDock23512acf-a922-4af4-b1d3-871a17563fb3_C_widget_gridCalenderEventOrder_ctl00_ctl06_RadDatetxtFirstTextBox_calendar_Top : [[2009,7,1], 1]},"_calendarWeekRule":0,"_culture":"en-US","_enableViewSelector":false,"_firstDayOfWeek":7,"_postBackCall":"__doPostBack(\u0027ctl00$MainCntrl$RadDock23512acf-a922-4af4-b1d3-871a17563fb3$C$widget$gridCalenderEventOrder$ctl00$ctl06$RadDatetxtFirstTextBox$calendar\u0027,\u0027@@\u0027)","clientStateFieldID":"ctl00_MainCntrl_RadDock23512acf-a922-4af4-b1d3-871a17563fb3_C_widget_gridCalenderEventOrder_ctl00_ctl06_RadDatetxtFirstTextBox_calendar_ClientState","enabled":true,"monthYearNavigationSettings":["Today","OK","Cancel","Date is out of range.","False"],"skin":"Office2007","specialDaysArray":[],"stylesHash":{DayStyle: ["", ""],CalendarTableStyle: ["", "rcMainTable"],OtherMonthDayStyle: ["", "rcOtherMonth"],TitleStyle: ["", ""],SelectedDayStyle: ["", "rcSelected"],SelectorStyle: ["", ""],DisabledDayStyle: ["", "rcDisabled"],OutOfRangeDayStyle: ["", "rcOutOfRange"],WeekendDayStyle: ["", "rcWeekend"],DayOverStyle: ["", "rcHover"],FastNavigationStyle: ["", "RadCalendarMonthView RadCalendarMonthView_Office2007"],ViewSelectorStyle: ["", "rcViewSel"]},"useColumnHeadersAsSelectors":false,"useRowHeadersAsSelectors":false}, null, null, $get("ctl00_MainCntrl_RadDock23512acf-a922-4af4-b1d3-871a17563fb3_C_widget_gridCalenderEventOrder_ctl00_ctl06_RadDatetxtFirstTextBox_calendar"));
});

There is the code I am using to add the control in the RadDock

Control widget = (Control)LoadControl(TagArr1[1]); //TagArr1[1] Control Url
WidgetsControl_CalenderComponent widgetControl = (WidgetsControl_CalenderComponent)widget;

dock.ContentContainer.Controls.Add(widget);
widgetControl.IsSchoolHomePage = SessionInfo.IsSchoolHome;

Please let me know, how I can I avoid these errors?

Thank in advance

Wrap one column, makes all columns wrap

I'm running into an issue, and want to know if anyone else is having the issue.

I have a grid with several columns. AllowScroll and UseStaticHeaders are both set to true.

Every apperas to function fine.

Now, I want to change ONE column so that it's content wraps.

So I set...

boundColumn.HeaderStyle.Wrap = true;
boundColumn.ItemStyle.Wrap = true;
boundColumn.FooterStyle.Wrap = true;

Since I am wrapping, I also set a width for the column

boundColumn.HeaderStyle.Width = Unit.Pixel(100);
boundColumn.ItemStyle.Width = Unit.Pixel(100);
boundColumn.FooterStyle.Width = Unit.Pixel(100);

However, when I do this, it appears that ALL columns begin to wrap, and all columns shrink to fit within the size of the grid.

Has anyone else run into this?

Thanks,
Kuba

FindControl in FormTemplate external of grid events

I am trying to access controls within the formtemple on an "external event" (happens to be a datasource_inserting, but can be anything).

All I have read so far have been on itembound/itemcreated or when a control within the grid raises the event.

Any suggestions?

[Solved] Questions regarding ASP.NET AJAX radControls

Hi there

I have some questions to get off my chest that have been bugging us here for a while now, as we have recently learnt that RadControls for ASP.NET has now been cut off, i was wondering if you could answer a few questions for us...

When we see ASP.NET AJAX we are put into the beleif that all the controls contain AJAX (on the fly) and so this will cause our application to fail its accessibility compliance, is this the case or have we just misunderstood the point and that we only fail when we use the Ajax radControl, and the other controls are exactly the same as the ASP.NET controls (with added useful features)

Hope to hear from you soon

Regards

Ahmed

Style issue with Ajax

Hi,

I have a tabstrip and checkboxList and i am updating the checkboxlist when user click on any tab. i am using style on server side. When the page is loaded first time then style applies but when i click on tab then style didn't apply and when i remove the ajax on chekboxList then style applies on postback but when i apply ajax then it didn't apply. so i think there is an issue with ajax.

My script is this:

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="tabStrip1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="chkBoxList1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManagerProxy>

<telerik:RadTabStrip ID="tabStrip1" runat="server" CausesValidation="False"
                                    DataTextField="col1" DataValueField="col2" OnTabClick="tabStrip1_TabClick"
                                    Skin="Web20">
                                </telerik:RadTabStrip>
                                <asp:CheckBoxList ID="chkBoxList1" runat="server"
                                     DataValueField="col2" DataTextField="col1"
                                    RepeatDirection="Horizontal">
                                </asp:CheckBoxList>

Server side code that bind the checkboxlist from the database.

chkBoxList1.DataSource = GetDatatable()
chkBoxList1.DataBind();

            foreach (System.Web.UI.WebControls.ListItem item in chkBoxList1.Items)
            {
                if (item.Text == "abc")
                {
                    item.Attributes.Add("Style", "padding-left:22px");
                }
                else if (item.Text == "abc11")
                {
                    item.Attributes.Add("Style", "padding-left:32px");
                }
                else if (item.Text == "def")
                {
                    item.Attributes.Add("Style", "padding-left:43px");
                }
                else if (item.Text == "1213")
                {
                    item.Attributes.Add("Style", "padding-left:52px");
                }

                item.Text = "";
            }
        }

Please tell me that how i can resolve this issue.

Thanks.

General advice needed

Hi all,

I am just about to re-write our web portal (200+ aspx pages) from the ground up, the technologies I am going to use are VS 2010, SQL 2008, ASP.NET AJAX (latest version might consider the beta!), IIS7. I am going to use master pages, user controls within the pages, a lot of the pages are going to have tabstrips, grids, treeviews, panels, and I want to use AJAX for the best performance. My first question is what do you think is the best way to use AJAX, e.g. Manager on the master page and proxies on the content pages, or just a manager on the content, I have nothing on the master page that needs AJAXing, that is all on the content pages. The next question is the use of user controls within an AJAX environment, again is it better to lots of user controls each attempting to do their own bit of AJAX with their own AJAX manager or again just use the proxies. Is it better (from a performance perspective) to not use user controls and attempt to get everything written directly into the content pages rather than lots of user controls.

A typical layout is going to be

Master page,
    Content page,
        Tabstrip,
            Usercontrol
            Usercontrol
            Usercontrol

or

Master page,
    Content page,
        Treeview,
            Usercontrol
            Usercontrol

any advice is welcomed.

Thanks

Alex

Second DataBind() fail in case of asynchronous task processing

Hi,
I'm porting our software to RadGrid component and I have following problem:

I'm bounding dataset to the Grid in function, which is called in asynchronous way. First call of .Rebind() or .DataBind() is successful. But after binding I'm changing some properties of the grid - e.g. width of grid columns, header text of grid columns etc. Then I'm trying to call .DataBind() (or .Rebind()) again - and this second call fail with error RegisterRequiresControlState can only be called before and during PreRender.

If I will not make the 2nd DataBind() call, then I will not see the visual changes, which I've done in async. task. Is it possible to somehow reshow the grid in async task?

I'm adding class code:

    
                public partial class _Default : System.Web.UI.Page  
        
                {

                    private DataSet Data

                        get
