Hi,
I am using RadGrid which contains Nested View Tamplate, inside the template I have a user control.
My problem is that I can't figure out how pass parameters from the template to the user control.

I tried this:

    
            <NestedViewSettings DataSourceID="SqlDataSource2"> 
        
                                <ParentTableRelation> 
        
                                   <telerik:GridRelationFields DetailKeyField="ID" MasterKeyField="ID" /> 
        
                                </ParentTableRelation> 
        
                            </NestedViewSettings> 
        
                            <NestedViewTemplate> 
        
                                <asp:Label ID="Label3" runat="server" Text='<%#Bind("ID") %>' ></asp:Label> 
        
                                <asp:Label ID="Label1" runat="server" Text='<%#Bind("source") %>' ></asp:Label> 
        
                                <ap:activityPanel source='<%#Bind("source") %>' jobId="123" ID="activityPanel" runat="server" Visible="true" /> 
        
            </NestedViewTemplate>

Both Labels holds the correct text, but the public variable "source" inside the "activityPanel" user control remains null.

How can I resolve this?
Thanks

[Solved] MIA: VS Extensions

I've got Q1 2010 installed on my machine and have noticed that the VS Extensions aren't there.

I'm pretty sure they're supposed to install with the main product. That's right isn't it?

How do I get them to install now?

RADMenu rendering problems in IE8

I have a radmenu, with multi column switched on.

If one of the items in the left hand column has children, then they render UNDER the items in the right hand column.

This has only been observed in IE, all other browsers (including on the mac) have rendered just fine.

you can download an AVI of the problem at:

Card View Layout Template sorting not working

i am working on a example based on "Card View" demo http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/cardview/defaultcs.aspx i am able to have it work just how i want it to, however i am having strange problems with the sorting functionality, not sure what i am missing
i have attached code and screenshot, i have listed the problem in 2 points belows

(1) The sort is not working altogether, i am able to click on the heading, its seems to refresh and adds a downward arrow (sort desc), but i don't see the records rearranged, i click on it again, it seems to refresh, but the downward arrow stays (does'nt change to upward arrow)

(2) if i am clicking on column 1, its highlighting(i have added sorted back color property to test this) and trying to sort column 2 with a desc arrow, this seems to be the norm for other columns too, ie if i click on column 5, its trying to sort column 6, when i click on column 1 for the second time it seems to be trying to sort column 1(but, point (1) above happens)

It seems to be the case that there is no way to find a menu item by its ID with server-side code. Is this correct? Please tell me I'm wrong.

Filter Generation of designer file failed

We have a working filter column that extends GridTemplateColumn.

Everything is working properly at runtime, but at design time we get this message:

Warning 1:

Generation of designer file failed: Telerik.Web.UI.GridColumnCollection must have items of type 'Telerik.Web.UI.GridColumn'. 'custom:FilteringColumn' is of type 'TIPWebCommon.FilteringTemplateColumns.FilteringColumn'.

We are using Visual Studio 2008 with SQL Server 2005.

less than character in symbol popup

Hello,

I am programmatically adding symbols using the Symbols.Add routine of the editor. The symbol popup displays all symbols correctly except for the less than '<' character for which it just displays a blank space. The greater than character is also added and it displays correctly.

Any help on this matter would be much appreciated,
Alex

Masked Textbox ViewStateModeById Issue

Hi,

Due to the nature of our application, we have to create controls dynamically, and move them from one parent to another during postbacks. This normally causes viewstate failed exceptions ("Failed to load viewstate. The control tree into which viewstate....") since control tree is modified during postbacks, however the issue is solved by using ViewStateModeById as suggested in another forum post.

This solution helped us all, except the RadMaskedTextBox control. Although we wrap it with ViewStateModeById attribute, it still causes viewstate failed exceptions when moved during postbacks. Below is how we wrapped it:

    <ViewStateModeById()>
    Public Class wrappedRadMaskedTextbox
        Inherits Telerik.Web.UI.RadMaskedTextBox
    End Class

The same method has been applied to many other controls, and they all worked fine including Telerik combobox, Telerik textbox (non mask input control) etc.

I really need help to solve this issue asap. If anyone can respond to this issue, that would be great. I also kindly ask you guys not to suggest me "disabling the viewstate" or "not dynamically creating or moving controls" since all those have valid reasons for our project. Also, regenerating the problem is fairly easy and straightforward.

Thanks in advance.

[Solved] version problem

Hi,

We had installed Rad controls from the link (http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q1-2010-version-2010-1-309.aspx) and started working on the rad scheduler. Now after upgrading it to the new version (http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q1-2010-sp2-version-2010-1-519.aspx), we are facing an issue with the scheduler. Please help us on the same.

The issue is that, on click of the date (number on the cell) in month view, this would take us to the day view. Now after upgrading to new version, we are getting an alert saying 'String not recognized as a valid DateTime'. Please help us solve this issue ASAP.

Thanks,
Vasanthi
