Hi,
I want to move my html code:

    
            <telerik:RadMenu ID="RadMenu1" runat="server" DataNavigateUrlField="Url"   
        
                        DataSourceID="XmlDataSourceForMenu" DataTextField="Text" DataValueField="Value">  
        
            </telerik:RadMenu> 
        
            <asp:XmlDataSource ID="XmlDataSourceForMenu" runat="server"   
        
                    DataFile="~/MenuConfig.xml" XPath="/Items/Item"></asp:XmlDataSource>

to c# code.
So I wrote in Page_Load:

    
            XmlDataSource XmlDataSourceForMenu = new XmlDataSource();  
        
            XmlDataSourceForMenu.ID = "XmlDataSourceForMenuID";  
        
            XmlDataSourceForMenu.DataFile = "~/MenuConfig.xml";  
        
            XmlDataSourceForMenu.XPath = "/Items/Item";  
        
            RadMenu1.DataSourceID = XmlDataSourceForMenu.ID;  
        
            RadMenu1.DataNavigateUrlField = "Url";  
        
            RadMenu1.DataTextField = "Text";  
        
            RadMenu1.DataValueField = "Value";

but I get an error
"The DataSourceID of 'RadMenu1' must be the ID of a control of type IDataSource. A control with ID 'XmlDataSourceForMenuID' could not be found. ".
How can I fix this bug?

accessing dynamically generated controls inside a PanelBarItem

I'm having trouble getting to the RadioButtonList control that is added dynamically when the page loads.
Here's a snippet of code that creates a RadPanelItem, add a RadioButtonList control to it, and then adds that to the RadPanelBar:

Dim

rdiobtnList As New RadioButtonList

rdiobtnList.ID =

"AssignmentRadioBtnList"

For Each Assignmentsdr As DataRow In AssignmentsDataSet.Tables(0).Rows

RowCount += 1

Dim li As New ListItem

li.Value = Assignmentsdr.Item(

"AssignmentListID")

li.Text = Assignmentsdr.Item(

"Assignment")

li.Selected =

False

rdiobtnList.Items.Add(li)

AssignmentPanelItem.Value =

"Assignments"

AssignmentPanelItem.Controls.Add(rdiobtnList)

AssignmentsRadPanelBar.Items.Add(AssignmentPanelItem)

Here is how I have the ASPX page setup:

<telerik:RadPanelBar ID="AssignmentsRadPanelBar" Runat="server" Skin="Web20" Width="150px">

</telerik:RadPanelBar>

I've looked through the FAQ's and the Tutorials, but none of the tutorials touch on adding RADPanelItems dynamically.

Any help would be very much appreciated.

ContentContainer's height automaticly set to auto?

This does that when content is 'bigger' than the container, it just hides it instead of showing scrollbars. Happened after the last hotfix.

Any suggestions on how to solve?

[Solved] DatePicker focuses on hidden shared calendar when picking a date. How to stop?

I did a search on focus and found two articles, but they don't seem to apply 100%

http://www.telerik.com/community/forums/aspnet-ajax/calendar/raddatepicker-validation.aspx

and

http://www.telerik.com/community/forums/aspnet-ajax/calendar/set-focus-after-date-selected.aspx

Both of these, it's a single DatePicker choosing a date and getting focus back.

I have about 30 dates on the page all using a hidden SharedCalendar at the top. When a user selects the date, they are sent to the top of the page.

Is there a way on the SharedCalender to send the focus back to the DatePicker that called it? Or do I need to set something on every DatePicker?

Was thinking something like..

<telerik:RadCalendar ID="calShared" runat="server" EnableMultiSelect="false" ClientEvents-OnDateSelected="ResetFocus" />

function ResetFocus(sender, args) {

//sender.focus();

}

but that didn't work.

[Solved] RadBinaryImage - General Info and Online Resources

RadBinaryImage gives you an easy way of showing an image stored as binary data in a database. The control can be used in any data bound control (Repeater, DataList, GridView, etc.) to display images which originate from binary image field in the data source. RadBinaryImage uses an internal http handler which streams the image from the binary source to the page in which it has to be visualized. The most important properties of the RadBinaryImage control are presented in the list below:

DataValue - property which specifies the source field from which the data will be passed as a byte array
Height - specifies the height of the binary image
Width - specifies the width of the binary image
AlternateText - the text that will replace the image when it is not available/cannot be streamed
ToolTip - the text that will be displayed in a browser tooltip when you hover the image
AutoAdjustImageControlSize - scales the image based on explicitly set width/height dimensions to avoid stretch or blur effect when its original dimensions do not fit. The default value is true.
HttpHandlerUrl - can be used to specify the location of a custom http handler which extends the default RadBinaryImage http handler. When not set, RadBinaryImage has its own handler which is invoked through the common Telerik.WebResource.axd handler.
ImageUrl - applicable when no DataValue is specified to gracefully degrade to regular asp Image mode.
ImageAlign - specifies the image alignment inside its container.

To get familiar with the control please follow these online resources:

[Solved] Hierarchical Grid - Refresh Parent after Insert

Hello,

I have a hierarchical grid that is configured to insert items in the second tier.
The parent grid (upper most tier) identifies the count of items in the second tier (as a grid cell).
How do I update the count in the parent grid after inserting an item in the child grid?
The child grid rebinds after the insert, but not the parent.
Thanks.

RadCombo - Selecting a Item with empty Text (string.empty) is not possible anymore ?!

Hello ,

i read a lot of Posts in the Forum but can't find a answer for the Problem.

I want to set a default empty ListItem into the RadCombo, which is loaded on demand.

The Empty Item should have a string.Empty as Text and the DataKey Type MinValue of the binded datasource as value.

For example

Text = string.Empty
Value = Guid.Empty().ToString()

or

Text = string.Empty
Value = int.MinValue.ToString()

Before I updated to the current Version (q1 2009) I used the Q3 2008 Version and all works as it should. Now I have the Problem that the Item is shown in the Combobox, but it is not selectable with a Mouse Click ?! I can Select It with Key Up/Down only, but that ist a help.

Just If I set the Text Like "------" or any other Text....
This is not what I want because a Empty Item should be really empty...

I read the workarround in this Forum but I want to set the empty with no Text = string.Empty.

Is It possible to undo the changes on this in the next version?

Kind Regards

Fabian
