RadGrid headers disappearing on select command

I have a RadGrid that is being configured dynamically at run time. The purpose is create a custom grid based on an arbitrary sql query. I'm adding a gridbuttoncolumn at runtime that has a select command. When this button is clicked, all the select links disappear and the column headers disappear as well. Any thoughts on what this issue may be?

RadEditor and StyleBuilder and Lists

I am having a problem with special lists in the RadEditor. I need to use special types of lists (roman numerals, symbols, letters, etc) which is an option available in the RadEditor's Style Builder. However, any time I attempt to apply these styles it just doesn't work.

I was able to reproduce this with the RadEditor in your demo section. (http://demos.telerik.com/aspnet-ajax/editor/examples/xhtmlvalidatortrackchangesformatcodeblockdialogs/defaultcs.aspx) Ive attached images that will show you the original bulleted list and then the bulleted list after I attempted to format it to be roman numerals (i, ii, iii, iv, ...).

The html for each list is as follows.
Original bulleted list:

<ul>

<li>

<em>Out-of-the-box XHTML-enabled Output...</em>

</li>

<li>

<em>Unmatched Loading Speed and Performance</em>

</li>

<li>

<em>Microsoft Word-like Spell-checking</em>

</li>

<li>

<em>Seven Ways for Pasting from Word</em>

</li>

<li>

<em>Multilevel Undo/Redo with Action Trails</em>

</li>

<li>

<em>Extended Functionality Through Integrated Controls</em>

</li>

</ul>

After Formatting with Style Builder:

<ul>

<li>

<em><span></span></em></li>

<span>Out-of-the-box XHTML-enabled Output...

Unmatched Loading Speed and Performance

Microsoft Word-like Spell-checking

Seven Ways for Pasting from Word

Multilevel Undo/Redo with Action Trails

Extended Functionality Through Integrated Controls</span>

<li><em></em>

</li>

</ul>

I did notice that for your upcomming Q1 release there is "Issue ID 4835 - IMPROVE StyleBuilder dialog for RadEditor." I wanted to find out if this issue is resolved with that, and if not I wanted to bring this to your attention.

Thank you!

SelectedIndex depending on datasource value

Well, I have seen similar problems and corresponding solutions on the forums, but none of those was applicable for this problem. I already have tried and searched almost any given solution on the forums here and around the internet, but unfortunately to no avail.

So, what exactly is the problem? I have got a RadComboBox which has an ObjectDataSource. This ComboBox has been placed in an EditItemTemplate within a RadListView. I want this RadComboBox to display the name of the currently selected customer as SelectedIndex (SelectedValue or Text). Items are filled based upon data out of an XmlDataSource object. The ObjectDataSource contains all possible customers.

Let's say I have inserted a new item with customer: "Customer1", but I'd like to edit this item. When you go into the EditItemTemplate view, I want to have the RadComboBox select (SelectedIndex/Value or Text) "Customer1" (which is based upon the XmlDataSource) from the ObjectDataSource.

My RadComboBox and ObjectDataSource look like:

<telerik:RadComboBox ID="RadComboBox1"

runat="server"

AllowCustomText="false"

DataSourceID="ObjectDataSource1"

DataTextField="Name"

DataValueField="Name"

DropDownWidth="128px"

EmptyMessage="-Customer-"

EnableAutomaticLoadOnDemand="true"

EnableVirtualScrolling="true"

Filter="Contains"

Height="150px"

ItemsPerRequest="10"

MarkFirstMatch="true"

MinFilterLength="2"

ShowMoreResultsBox="true"

Width="128px">

</telerik:RadComboBox>

<asp:ObjectDataSource ID="ObjectDataSource1"

runat="server"

SelectMethod="GetCustomers"

TypeName="RadControlsWebApp1.Customers">

</asp:ObjectDataSource>

The SelectMethod="GetCustomers" returns a List<Customer> object. A Customer is just a simple class which holds a (string) name. You could actually just use a List<string> for the same purpose.

The XML file (XmlDataSource object) looks like:

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

<Activities>

<Activity Customer="Customer1" Project="Project1" />

<Activity Customer="Customer1" Project="Project2" />

<Activity Customer="Customer2" Project="Project2" />

<Activity Customer="Customer3" Project="Project3" />

</Activities>

I have tried to set the Text property of the RadComboBox as follows: Text='<%# Bind("Customer") %>' and setting the RadComboBox.SelectedIndex or RadComboBox.SelectedValue properties programmatically, but as I already mentioned, without results. Perhaps I tried to set the properties in the wrong event(s).

Reorder chart legend labels

Hi. I have been trying to figure out how to reorder the items listed in the chart legend, but so far to no avail. I'd like to do something along the lines of this:

   List<Telerik.Charting.ChartLabel> legendItems = new List<Telerik.Charting.ChartLabel>();

   legendItems.Add(RadChart1.Legend.Items[0]);
   legendItems.Add(RadChart1.Legend.Items[2]);
   legendItems.Add(RadChart1.Legend.Items[5]);
   legendItems.Add(RadChart1.Legend.Items[1]);
   legendItems.Add(RadChart1.Legend.Items[4]);
   legendItems.Add(RadChart1.Legend.Items[3]);
   legendItems.Add(RadChart1.Legend.Items[6]);

   for (int i = 0; i < 7; i ++)
   RadChart1.Legend.Items[i] = legendItems[i];

But when I run this the RadChart1.Legend.Items appears empty. I am sure I am missing something here and was hoping you'd be able to lend a hand.

I would essentially like to know how I can reorder the labels that appear in the legend block.

Thank you!

Comments Column

Hey everyone,

Our current asp.net web application we use to manage our documents just records the URL of where the file is located (in a database). Within a gridview control the users can click the link to view the document. The gridview also has another column that can store a comment pertaining to the file, also located in a database.

Is it possible to have a comment column within the FileExplorer control ? I imagine a database of some sort will still need to be used to hold the comment information.

Any ideas?

RadTab with Close - IE6 rendering issue

I am trying to use a RadTabStrip control with a Close button on every tab. The Close button is created using TabTemplates.

Everything works fine, with the exception of IE6, where even though I use the styles provided in the Telerik example for the IE6 to fix the line-height bug, it still does not render properly. The bottom of the tabs is slightlly missaligned.

I have included a screen shot of the problem (UISample.JPG). Also, bellow I listed the sample aspx code and the css I am using.

I have tried to play with the css style, but I did not manage to get it to work properly. Does anybody have a solution for this ?

Thanks a lot for the help !

This is the aspx code:

<head runat="server">

<title>Untitled</title>

<link rel="stylesheet" type="text/css" href="styles.css" />

</head>

<body>

<form id="mainForm" runat="server">

<telerik:RadScriptManager runat=server ID="ScriptManager"></telerik:RadScriptManager>

<div>

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0" Skin="Vista" ScrollChildren="true" ScrollButtonsPosition="Middle" Orientation="HorizontalTop">

<TabTemplate>

<div class="textWrapper">

<%# DataBinder.Eval(Container, "Text") %>

</div>

<span class="ie6shim"></span>

<img src="Images/Close.gif" alt="Close" onclick="deleteTab('<%# DataBinder.Eval(Container, "Text") %>')" />

<TabTemplate>

<Tabs>

<telerik:RadTab runat="server" Selected="True" Text="Tab1"></telerik:RadTab>

<telerik:RadTab runat="server" Text="Tab2"></telerik:RadTab>

<telerik:RadTab runat="server" Text="Tab3"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

</div>

</form>

</body>

This is the styles.css file:

.tabStrip

{

position:absolute;

top:0;

}

.rtsIn img

{

vertical-align:middle;

width: 14px;

height: 14px;

margin-left: 10px;

}

.rtsIn .textWrapper

{

display: inline;

}

/* IE6 fixes for line-height bug */

* html .rtsIn img

{

margin-bottom: 10px;

}

* html .rtsIn .textWrapper

{

float: left;

height:26px;

}

* html .rtsIn .ie6shim

{

height: 26px;

display: inline-block;

}
