ASP TreeView to RadTreeView

I'm converting my existing ASP TreeView to a RadTree view. I'm getting hung up on the child node syntax.

This is what I currently have for my ASP TreeView:

t1.FindNode(rs.GetString(4).ToString().ToLower()).ChildNodes.Add(node);

t1.FindNode(rs.GetString(4).ToString().ToLower()).Collapse();

I'm not sure what the equivalent would be for RadTreeView.

Thanks.

Update command not firing properly if we load the radgrid dynamically

Hi,

We are loading a rad grid dynamically on dropdown selection change event.
Everything works fine when number of rows in a grid are less than the pagesize.
When number of rows are more than the page size i.e. when we have more than one page update event is not getting fired.
It fires the ItemCommand event but in itemcommand event e.cancelled is coming as true.
Please check.

RedScheduler & Resources Issue

Hi All,

I'm new to the Telerik comunity and control suite, and after seeing the demo's of the RadScheduler i was blown awa. I've started evaluating whether this control will be able to be encorporated into our creaking architecture and in doing that i've come across a problem i can't quite get my head around. Please note that this is currently using the default XML file for the data provider (i haven't got round to using our database yet).

I've put the following code in the ASPX page:

<telerik:RadScriptManager ID="sman" runat="server" EnableTheming="false"/>

<telerik:RadScheduler ID="radCalendar" runat="server" AdvancedForm-Enabled="true" StartEditingInAdvancedForm="true" StartInsertingInAdvancedForm="true" />

And the following code in the code behind (this is to programmatically add our items to the dropdown, it will be from a database but i'm hardcoding this to mock this for testing purposes).

protected void Page_Init(object sender, EventArgs e)

{

ResourceType priority = new ResourceType("PriorityLevel");

radCalendar.ResourceTypes.Add(priority);

radCalendar.Resources.Add(new Resource("PriorityLevel", 1, "Low"));

radCalendar.Resources.Add(new Resource("PriorityLevel", 2, "High"));

        

      ResourceType user = new ResourceType("S7User");

      radCalendar.ResourceTypes.Add(user);

      user.AllowMultipleValues = true;

      radCalendar.Resources.Add(new Resource("S7User", 8, "Iain"));

      radCalendar.Resources.Add(new Resource("SUser", 9, "Nick"));

      radCalendar.Resources.Add(new Resource("S7User", 10, "Paul"));

      radCalendar.Resources.Add(new Resource("S7User", 11, "Stephan"));

radCalendar.Provider = new XmlSchedulerProvider(Server.MapPath("~/App_Data/Appointments.xml"), true);

}

The 'Priority' field now appears as a drop down, as does the S7User, these save too perfectly into the 'Appointments.xml' file, but, when i try to reopen the calendar i get the error:

Cannot find resource of type 'PriorityLevel' with Key=1 for appointment with ID=41.

The XML that is saved in the 'Appointments.xml' file is as follows:

<?xml version="1.0" encoding="utf-8"?>

<Appointments>

<NextID>42</NextID>

<Appointment>

<ID>41</ID>

<Subject>asdfasdf</Subject>

<Start>2011-06-15T09:30Z</Start>

<End>2011-06-15T10:30Z</End>

<Resources>

<PriorityLevel Key="1" />

<S7User Key="8" />

</Resources>

</Appointment>

</Appointments>

Can anyone offer any guidance as to why this is happening please? It works when I have the resources in the XML file, but taking them out breaks it, even though they are added to the control. One thing to note is in the Page_Init they are added to the 'Resources' collection in the control.

Any help is greatly appreciated.

High CPU of RadAjaxPanel

I have a web page uses 17 RadAjaxPanels and one RadAjaxLoadingPanel. This is to allow user load part of the data on page upon users' request.

But this page failed in our load test of 50 users.

I noticed if I expand one RadAjaxPanel on browser, the CPU usage will go up to over 30% for a moment then comes down. In case of 30 concurrent users expanding and collapsing panels, the CPU usage will go up to and stay at 100%.

Is this normal? Are there any ways I can make RadAjaxPanel less heavy on CPU?

Thanks a lot.

Iterating over filter expressions

In the ApplyExpressions event, I need to iterate over the RadFilterApplyExpressionsEventArgs.Expressions collection. It appears that to access specific values of each filter expression (field name, field type, view state, value, etc.), you need to cast each filter expression to its specific derived type. The only property exposed at the RadFilterExpression base type level is FilterFunction.

Basically I'm looking for the best way to iterate over a collection RadFilterExpressions, and access the specific properties of each instance. What makes this a little more complex that you'd expect is that each filter expression is composed of a number derived types - with the filter properties and values exposed by different types in the chain. What's the best way to access the specific filter expression properties?

Can anyone point me to a code example?

RadGrid ClearFilter

I'm usig the clearfilter functionality as described in the below demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx
You can see in the demo, type something in the filter box and before filtering(before clicking enter or tab) if you click on clear filter button, it is filtering the grid instead of clearing the filter text box as it is firing the filtercommand..Is there a way to fix this.

ComboBox loses list items after postback

Hi,

I am using RadAjaxPanel in master page as shown below:

<telerik:RadAjaxPanel ID="rapContents" runat="server" EnableAJAX="true" OnAjaxSettingCreating="rapContents_AjaxSettingCreating">

<asp:ContentPlaceHolder ID="phContents" runat="server">

</asp:ContentPlaceHolder>

</telerik:RadAjaxPanel>

And in the content page I used a radcombobox, the code is below:

<telerik:RadComboBox ID="rcbSP" runat="server" DataValueField="ID" DataTextField="Name"

EmptyMessage="None" HighlightTemplatedItems="true" AllowCustomText="true" Width="180"

OnClientDropDownClosed="onDropDownClosing"><ItemTemplate>

<asp:CheckBox runat="server" ID="chkSP" onclick="onCheckBoxClick(this, 'SP')" />

<asp:Label runat="server" ID="lblSP" AssociatedControlID="chkSP">

<%

# Eval("Name")%>

</asp:Label>

</div>

</ItemTemplate>

</telerik:RadComboBox>

//Combobox Binding - only binding first time the page loads

this.rcbSP.DataSource = LU_ServerPurposeBLL.GetList(false);

this.rcbSP.DataBind();

Now my issue is, when I have a postback in the content page, the data (list items) in the combobox is lost and displaying "None" (the empty message).

Please help me in resolving the issue. Thanks in advance.

Heirarchical TreeView - NonUnique data

Hi,

I wanted to populate a Treeview based upon a DataTable retrieved from the AdventureWorks database using a recursive CTE in a Stored Procedure. It is the good old recursive problem of components witin components within a product. The SP is:

USE [AdventureWorks]

GO

/****** Object: StoredProcedure [dbo].[CreateProductComponentHeirarchyForProduct] Script Date: 05/18/2011 20:44:38 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

ALTER PROCEDURE [dbo].[CreateProductComponentHeirarchyForProduct]

@ComponentID int

AS

BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from

-- interfering with SELECT statements.

SET NOCOUNT ON;

; WITH BillOfMaterialsCTE

(

BillOfMaterialsID,

ProductAssemblyID,

ComponentID,

Quantity,

Level

)

AS

(

SELECT bom.BillOfMaterialsID,

bom.ProductAssemblyID,

bom.ComponentID,

bom.PerAssemblyQty,

0 as Level

FROM Production.BillOfMaterials bom

WHERE bom.ComponentID = @ComponentID

UNION ALL

SELECT bom.BillOfMaterialsID,

bom.ProductAssemblyID,

bom.ComponentID,

bom.PerAssemblyQty,

Level + 1

FROM Production.BillOfMaterials bom

INNER JOIN BillOfMaterialsCTE bomCTE

ON bom.ProductAssemblyID = bomCTE.ComponentID

WHERE bom.EndDAte IS NULL

)

SELECT

bomCTE.ProductAssemblyID,

p.ProductID,

p.ProductNumber,

p.Name,

p.Color,

bomCTE.Quantity,

bomCTE.Level

FROM BillOfMaterialsCTE bomCTE

INNER JOIN Production.Product p

on bomCTE.ComponentID = p.ProductID

END

I used the following method to populate a RadTreeView on a page:

public void SetResults(DataTable results)

{

this.ProductsRadTreeView.DataSource = results;

this.ProductsRadTreeView.DataFieldID = "ProductAssemblyID";

this.ProductsRadTreeView.DataFieldParentID = "ProductID";

this.ProductsRadTreeView.DataTextField = "Name";

this.ProductsRadTreeView.DataBind();

}

When it hits the DataBind() call, the error message is: These columns don't currently have unique values.

This is no surprise to me. I did not expect them to be unique It is a recursive algorithm where components can be used in more than one component/product, so of course there will be duplicates.

Can the RadTreeView display such a ResultSet?

Cheers

TreeView
