I'm building a tree dynamically server-side and cannot figure out a way to optionally add an image to the right side of the tree node.

In a regular TreeView, I overrode the TreeNode to handle the RenderPostText() method to allow me to optionally insert my own image in the rendered HTML, but that method does not appear to be supported on RadTreeNode().

I know you can use CSS .rtImg to add a permanent image, but I'm not sure how to use that method server-side (if you even can) to have the impage displayed on only some nodes.

Is there another method I am missing?

Connection to RadPivotGrid

I am trying to connect to a cube using C#. When I connect it through my aspx page it works without any issues. But I would like to do it using code. I tried this code - but I am not able to do it. Please let me know what I should fix..

This is my aspx page

<tlrk:RadPivotGrid AllowFiltering="true" AllowSorting="true" ID="RadPivotGrid1" Width="100%"
RowTableLayout="Tabular" FieldsPopupSettings-AggregateFieldsMinCount="2" AllowPaging="true"
PageSize="20" runat="server" EnableConfigurationPanel="true" EnableZoneContextMenu="true"
AggregatesPosition="Rows" EnableToolTips ="true" Skin="Vista">
<PagerStyle AlwaysVisible="true" />
<OlapSettings ProviderType="Adomd"> </OlapSettings>
<RowHeaderCellStyle Width="100%" />
<ConfigurationPanelSettings Position="left" LayoutType="Stacked" DefaultDeferedLayoutUpdate="true" />
<ClientSettings EnableFieldsDragDrop="true"><Scrolling AllowVerticalScroll="false" ScrollHeight="1000px" /> </ClientSettings>
</tlrk:RadPivotGrid>

And in my c# I did this -

protected void Page_Load(object sender, System.EventArgs e)
{
SetupAdomdConnection();
}
private void SetupAdomdConnection()
{
AdomdDataProvider provider = new AdomdDataProvider();
AdomdConnectionSettings settings = new AdomdConnectionSettings();
settings.Cube = "cubeName";
settings.Database = "DBName";
settings.ConnectionString = "Provider=MSOLAP;Data Source=XXXXX;Initial Catalog=DBName;";
provider.ConnectionSettings = settings;
}

[Solved] Reset Built-In Dock State Persistence

Hi,

I have a RadDockLayout control with 2 zones and 4 dock and I want to remember the positions and states of the docks. The Built-In Dock State Persistence works for me (other examples change the size of the docks when loading).

However, I would like to implement a 'Reset Layout' button. How do you clear the built-in dock states?

Thanks in advance,
Matt

[Solved] Waiting for an Ajax Request in progress to end.

Hello,

I am working on a project with a RadGrid and a RadTreeView.
Each time the user clicks on a node it fills a RadGrid with data.
The controls work in an Ajax environment.
Pressing on a RadTreeView node influences the RadGrid.
Sometimes it takes time to load data into the RadGrid.

The project requirement is that when user clicks on a node in the RadTreeView during an AJAX request/postback, show a JS alert to the user to wait for the reply and only then make another request.

How to perform this?

Thank,
Daniel.

Updating a RadGrid from a PanelBar template

I have a HeaderTemplate for a RadPanelItem that contains a LinkButton. In the template constructor I pass an ID value that I need the LinkButton to use. The idea is that the PanelBar grows dynamically based on a query. That works fine using the template.

My issue comes in when I try to click the LinkButton to update the RadGrid. Since the template is a class of its own, it cannot directly reference the RadGrid for passing it a new DateTable based on the ID value, stored within the template.

I've tried passing a callback function to the template constructor using System.Action<string>. I then try to attach the callback as an EventHandler to the LinkButton's Click event. So far this hasn't done anything for me.

Template:

public class TelerikTemplates

{

public class PanelTemplate : ITemplate

{

private readonly Label title;

private readonly LinkButton totalButton;

public PanelTemplate(string pTitle, int pTotal, string pId, System.Action<string> callback)

{

title = new Label();

title.CssClass = "panelTitle";

title.Text = pTitle;

totalButton = new LinkButton();

totalButton.CssClass = "totalButton";

totalButton.Text = pTotal.ToString();

totalButton.Click += delegate(object sender, System.EventArgs e) { callback(pId); };

}

public void InstantiateIn(Control pContainer)

{

pContainer.Controls.Add(title);

pContainer.Controls.Add(totalButton);

}

WebForm Code Behind

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

}

using (DataTable data = GetData())

{

foreach (DataRow dr in data.Rows)

{

RadPanelItem titlePanel = new RadPanelItem();

titlePanel.HeaderTemplate = new TelerikTemplates.PanelTemplate((string)dr["RuleName"], (int)dr["AccountTotal"], (string)dr["RuleId"], populateGrid);

RadPanelItem subPanel = new RadPanelItem();

subPanel.ContentTemplate = new TelerikTemplates.ChartAndTableTemplate(dr);

titlePanel.Items.Add(subPanel);

panelBar.Items.Add(titlePanel);

}

public void populateGrid(string pId)

{

grid.DataSource = GetGridData(pId);

grid.Rebind();

}

Problem styling menu

I have a RadMenu on my page that I am having problem styling.
The attached snapshot shows how it looks currently. The Quick Links is a menu, The child item keeps wrapping and looks wierd.

I have custom css and I am not using any Telerik base styling. When the width is 100px, the rSlide div is set to 0px width (the container that creates the sliding animation). when the slider is set to 100%, the rSlide is like 14px wide, which is way smaller then the full size of the RadMenu and we are unable to figure this out.

.upper_nav .RadMenu li {

border: none;

padding: 0;

position: relative;

}

.upper_nav .RadMenu .rmHorizontal,

.upper_nav .RadMenu .rmVertical {

padding: 0;

}

.upper_nav .RadMenu .rmRootLink {

font-size: 12px;

}

.upper_nav .RadMenu .rmRootLink:link,

.upper_nav .RadMenu .rmRootLink:visited {

color: #536ba2;

}

.upper_nav .RadMenu .rmRootLink:hover,

.upper_nav .RadMenu .rmRootLink:active,

.upper_nav .RadMenu .rmRootLink:focus {

color: #3c3d5e;

background: none;

border: none;

}

.upper_nav .RadMenu .rmSlide {

position: absolute;

display: none;

}

.upper_nav .RadMenu .rmVertical .rmItem {

display: block;

}

.upper_nav .RadMenu .rmVertical .rmItem span {

width: 100% !important;

}

Not Implemented JavaScript error under IE9 with Q3 2013 SP1

With Q3 2013 SP1(2013.3.1114) you may experience JavaScript errors thrown in Internet Explorer 9. This problem may be observed on a machine that does not have audio services started and no audio drivers installed (e.g., MS Windows 2008 Server with no audio device).

The problem lies within the HtmlAudioElement implementation in Internet Explorer – since the OS is unable to play any sound the canPlayType method of the HtmlAudioElement throws Not Implemented exception that breaks further executions of RadControls’ scripts.

We have already handled this problem and the fix will be available in the upcoming internal builds (since 2013.3.1210) and official release (Q1 2014). In case this issue is a showstopper for your current project and you cannot wait for the next official release and / or cannot use an internal build, you can use the following temporary workaround:

Place the following script in the <head> section of the page:

if(typeof(HTMLAudioElement) !== 'undefined' && HTMLAudioElement.prototype && HTMLAudioElement.prototype.canPlayType) {

var org = HTMLAudioElement.prototype.canPlayType;

HTMLAudioElement.prototype.canPlayType = function(typeString) {

var result = "";

try{

result = org(typeString);

}

catch(e) { }

return result;

}
