I'm working on some JavaScript to set the width of the dropdown list for a RadComboBox to the widest item in the list. Is there a client-side DropDownWidth property I can use for this? I didn't see any and so I was trying to set the width of the div containing the dropdown (I use the clientid of the RadComboBox with "_DropDown"). But using the following isn't setting the width:

var ddl = document.getElementById("MainContent_RadComboBox1_DropDown");

ddl.style.width = maxWidth + 'px';

maxWidth is the width of the longest item in the droplist.

Thanks for the help!

In IE7 Only - With Multiple RadListBoxes, they disappear but still in HTML markup

We have a custom user control that has RadListBoxes. We populate the RadListboxes with dynamic Templates in the OnIt method.
sample:

override protected void OnInit(EventArgs e)

{

//

// CODEGEN: This call is required by the ASP.NET Web Form Designer.

//

InitializeComponent();

if (NumberOfColumns == 1)

{

ShelfListBox.ItemTemplate = new DefaultListBoxTemplate();

CartListBox.ItemTemplate = new DefaultListBoxTemplate();

}

else if (NumberOfColumns == 2)

{

ShelfListBox.ItemTemplate = new TwoColumnListBoxTemplate();

CartListBox.ItemTemplate = new TwoColumnListBoxTemplate();

}

else if (NumberOfColumns == 3)

{

ShelfListBox.ItemTemplate = new ThreeColumnListBoxTemplate();

CartListBox.ItemTemplate = new ThreeColumnListBoxTemplate();

}

base.OnInit(e);

}

Right now we have a page that has 6 of our custom control.
DefaultListBoxTemplate Code:

/// <summary>

/// DefaultListBox ItemTemplate one column

/// </summary>

public class DefaultListBoxTemplate : ITemplate

{

/// <summary>

/// Defines the <see cref="T:System.Web.UI.Control"/> object that child controls and templates belong to. These child controls are in turn defined within an inline template.

/// </summary>

/// <param name="container">The <see cref="T:System.Web.UI.Control"/> object to contain the instances of controls from the inline template.</param>

public void InstantiateIn(Control container)

{

var label = new Label

{

ID = "LabelListItem"

};

label.DataBinding += new EventHandler(LabelListItemDataBinding);

container.Controls.Add(label);

}

/// <summary>

/// Handles the DataBinding event of the LabelListItem control.

/// </summary>

/// <param name="sender">The source of the event.</param>

/// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param>

private static void LabelListItemDataBinding(object sender, EventArgs e)

{

var label = (Label)sender;

var item = (RadListBoxItem)label.BindingContainer;

var listItemText = DataBinder.Eval(item.DataItem, "Property1") as String;

label.Text = listItemText;

}

Everything renders correctly on the page, but for some reason in IE7 only, the display of the radlistboxes disappear. If the page does something on the client side; some of the radlistobxes reappear and some disappear. very strange occurrences in IE7. Everything works correctly in IE8 or higher, Firefox and chrome.

tried attaching code in zip file...

Customize Series Item Label position

Guys,

I have created a stacked bar chart and I want the Series Item label to be shown besides the segment.
As of now it shows above the segment. I played around with the API and found that it can be positioned either inside or outside.
Can I somehow place the text label besides the segment?

Cheers,
Nitin

ValidationSummary not working in it's own asp:Panel

I have validaiton setup on some of my input controls, and a RadAjaxManagerProxy setup on the page.

On first page load my validation is working. But after ajaxifying the page and when the RadAjaxManager refreshes the Ajax content, the validation doesn't work anymore.

I have read this article (http://www.telerik.com/help/aspnet-ajax/ajxlimitations.html) re. RadAjax and Validators which suggest placing the validation summary in it's own asp:Panel, but it's still not working.

Any ideas?

<asp:Panel ID="validationSummaryPanel" runat="server">

<asp:ValidationSummary ID="newClientValidationSummary" runat="server" ShowMessageBox="true"

ShowSummary="false" ValidationGroup="newClientGroup" />

</asp:Panel>

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="addClientButton">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="leftContainer" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="validationSummaryPanel" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">

</telerik:RadAjaxLoadingPanel>

Exploded pie chart

Please assist. I am using Q1 2010 and am trying to implement an exploding pie chart with ajax enabled. The chart datasource is a SQLServer stored procedure.

I just can't seem to find any examples that actually work in my project. There doesn't seem to be an

ChartSeriesItem.Exploded

property any longer--- are there any recent examples like this one which looks like it is really old?

jquery plugin problem

Hello.

I'm trying to use "inplace editor" jquery plugin (http://jquery-in-place-editor.googlecode.com/svn/trunk/demo/index.html) on page which use telerik rad ajax controls. I have added necessary scripts fallow the instruction (http://www.telerik.com/help/aspnet-ajax/using-jquery-plugins.html) but it doesn't work. When I move my code to plain html page (not aspx) with jquery (without telerik) everything works fine (like on demo page). To be sure I have tested the example from telerik help with BlockUI and this works fine to, so probably the inplace editor" plugin use some more advanced functionalities of jQuery.
Anyone was successfully to integrate this plugin into aspx with telerik scripts registered?

I will be grateful for any help,
Lukas

How can I get parent DataKeyValues from a child ItemCommand event? I need the CustomerId value in order to pass this parameter to another page.

Any idea?
Thanks a lot in advanced,

Paging, binding, RadTabStrip

I have a page that contains a radtabstrip with five tabs.
There is a RadMultiPage that corresponds to each tab.
Each RadMultiPage contains a grid, and each grid does some item manipulation on _OnItemDatabound. Each grid also has paging enabled.
Everything works fine until I go the next page in grid X on Tab X. If I then click Tab Y, Grid Y has lost the changes that had occurred when it was databound. If I forced the grid to rebind, it would fix the problem, but I would rather not rebind this grid.
What causes this grid to revert to it's original state (before onItemDatabound modified the column content)?
