Select value Dynamically in a combo box with treeview control

When I am loading the page I want to select a value in Combobox with Treeview.

I am using following code, It selects correct value from a tree view but combo box doesn’t show this selected value, it always says “Select”.

How to I a show selected value on page load?

I am using following code.

Dim tvCategory As RadTreeView = DirectCast(cboCategory.Items(0).FindControl("tvCategory"), RadTreeView)

tvCategory.FindNodeByValue(LCase(project.SubscriberCategory.Id.ToString)).Selected = True

How can I perform an update in a formtemplate without closing

I am writing a app that sends email to recipients based on templates.

Templates have a one to many relationship to recipients

I'm using radgrid to display the email templates and do inserts/updates. With a formtemplate popup with another radgrid on it for the recipients.

When I'm inserting a new email template, I have the situation where I need to perform the row insert without closing the formtemplate / popup, so I have a key for the recipients.

Is there a way to do this sort of thing?

Client-side filter

Anyone have any examples that show how I would do the following.

I need a radtextbox and a radgrid. The grid by default shows all the data table's records but when the user starts typing into textbox, it automatically starts filtering the grid client-side (keyup event).

Would this be something I could use as a guide by changing out the combobox for textbox? http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/gridinxmlhttppanel/defaultvb.aspx

LinqDataSource and Stored Procedures

I am trying to get a basic grid working using a linqDataSource which is populated with a stored procedure.

    
                <div style="width:100%;overflow:auto;"> 
        
                    <telerik:RadGrid ID="RadGrid1" Width="3000px" AllowPaging="True" PageSize="15" runat="server" AllowSorting="true" 
        
                        GridLines="None" DataSourceID="linq_mySP"> 
        
                        <MasterTableView Width="100%" /> 
        
                        <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                        <FilterMenu EnableTheming="True"> 
        
                            <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                        </FilterMenu> 
        
                    </telerik:RadGrid> 
        
                </div> 
        
                 <asp:LinqDataSource AutoPage="True" ID="linq_mySP" runat="server"></asp:LinqDataSource>

    
            Imports System.Data 
        
            Imports Telerik.Web.UI 
        
            Partial Class gridPages_telerikGrid 
        
                Inherits System.Web.UI.Page 
        
                Protected Sub linq_mySP_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceSelectEventArgs) Handles linq_mySP.Selecting 
        
                    Using context As New DataClassesDataContext 
        
                        Dim fromdate As DateTime = DateAdd(DateInterval.Year, -5, DateTime.Now) 
        
                        Dim todate As DateTime = DateTime.Now 
        
                        e.Result = context.spTest(49, fromdate, todate) 
        
                    End Using 
        
                End Sub 
        
            End Class

The problem I have is that on page load I get an 'object reference not set to an instance error', which I believe it is refering to the grid. I can get the grid to work not using linqDataSource by binding the data to the grid on page load, but i need to get it working using a linqDataSource.

Any help would be much appreciated.

filter on column with client method when column is not displayed? GridTableView

Hi im using the GridTableView.filter() client side function and it works great.
But only on columns that are actually displayed in the grid.

I would like to call GridTableView.filter() on a column in the data source that is not displayed.
I have added the column name to MasterTableView ClientDataKeyNames property.

Is this possible? How do I do it? I guess a work-around would be including the columns with a 0 width - but i'd prefer something more efficient.

Thank you!
Topher

RadSpliter/RadPane Cross Browser compatibility issue

Hello
I have a RadSplitter with two side-by side rad panes.
The right pane has a couple of controls inside, not fully filling the pane
In IE7 and IE8 compatibility mode, objects are centered in the right pane
In IE8, Safari and others, objects are "left justified". I have not been able to find the pane or splitter property that centers them.
Please see attachment
Thanks!

Relevant code follows

<

telerik:RadSplitter id="RadSplitter1" runat="server" skin="Office2007"

height="500px" width="950px" BorderSize="0" BorderStyle="None" >

<

telerik:RadPane id="LeftPane" runat="server" width="150px" Scrolling="None" Collapsed="false" BackColor="White">

<telerik:RadPanelbar ID="BarraCli" runat="server" skin="Vista" ExpandMode="FullExpandedItem" Height="500px"

Width="100%" CssClass="BarraCli">

<Items>

<telerik:RadPanelItem runat="server" Text="xxxxx" PostBack="false" Expanded="false" Value="0">

IE8 and ASP Button rendering

I've upgraded from 2008 Q3 to 2010 Q1. The issue I am having is that now ASP Buttons appear in IE8 with a section missing and no longer size according to my set widths like they did in the earlier version. All my ASP Buttons are in table cells (<td>)

If I switch to compatibility view for IE8, the problem goes away. See attached for before and after. Note that if I removed the FormDecorator, it works fine in either view mode (just without decoration.)

Any ideas? I've searched the threads, but didn't find a match to this issue that worked. Would someone point me to the fix or a thread that addresses this issue? Thanks.
