strange border appears when inherit from raddropdownlist

Hello,

I created a new combobox class and used the RadDropDownList as base class, but when I override the CreateDropDownListElement function and return my own element, a black border appears:

public class TestComboBox : RadDropDownList

{

public override string ThemeClassName

{

get

{

return typeof(RadDropDownList).FullName;

}

set

{

base.ThemeClassName = value;

}

protected override RadDropDownListElement CreateDropDownListElement()

{

//return base.CreateDropDownListElement();

return new TestElement(this);

}

public class TestElement : RadDropDownListElement

{

public TestElement()

{

//

}

public TestElement(object owner)

: base(owner)

{

//

}

Localization of the GridView and loading saved layouts

Hi,

we have a localization problem. We have done the localization of the grid view. But now we have the following behaviour: The user starts the application the first language. As requested by the customer, the layout of the grid will be automatically saved. Now the user changes the language. The application starts and loads the layout, and everything is translated into the new language except the columns, because they are read from the layout file in the old language.

What is the right strategy to deal with this problem?

Thanks,
Michael

Trackbar Range

Hello,

I'm trying to use the RadTrackBar with Range mode, but I cannot access the values of the two ranges. I see in the documentation that I must use Ranges_CollectionChanged, but I don't understand how to access this function.

Do you have any example how to use two ranges.

Thank you,
Eduard

DropDownList > ListElement > Font

RadControls for WinForms Q2 2010 / 2010.2.10.071

I am trying to set the Font for the list elements of a drop down list. I am able to set the font using the Properties window but the setting does not effect the list elements when the application is run. At run time, the application creates an array of RadListDataItem which is used as the data source. I have also tried setting the Font property of the individual RadListDataItems.

Setting the font for the DropDownList works correctly for the text box associated with the list.

Thanks,
Scott

Property Grid Combo Editor Changes the selected value when you double click to start edit

If a property grid combo editor is double clicked to start an edit the value will cycle through the available values.

Here is a really simple code example for this. If you just double click to start the edit on the MyEnum field you will notice that the value will keep changing every time you start the edit.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

namespace PropertyGridTest

{

public partial class Form1 : Form

{

MyObject theObject = new MyObject();

public Form1()

{

InitializeComponent();

theObject.MyEnum = MyEnum.One;

theObject.Name = "test";

radPropertyGrid1.SelectedObject = theObject;

}

public enum MyEnum { One, Two, Three, Four, Five };

public class MyObject

{

public string Name { get; set; }

public MyEnum MyEnum { get; set; }

public MyObject() { }

}

AutoCompleteBox Scrollbar bug

Hello all,

I'm currently trialing both the Winform and Reporting suites and have been very impressed. I have however come across some unwanted behaviour which I think is probably a bug.

The problem comes when you populate the AutoCompleteBox and start a search returning enough results to need the scrollbar. When clicking and dragging the scroll bar to scroll - if the cursor is not positioned directly over the scrollbar at the time you release the mouseclick, the dropdown list is closed an item is added to the selection.

If I encounter a problem like the above after purchasing the Telerik tools how long does it take to normally find a solution? I'm basically looking for confirmation I wouldn't have to wait for a Quarterly update.

Many Thanks.

BUG: RadTextBox Shift+Tab

Hi,

When I have a few instances of the RadTextBox on a Form, and pressing Shift+Tab I have to press it twice to get the focus to the previous textbox. Pressing Tab only to get the focus to the next textbox works fine.

Best regards.

Export Grid that has a group panel

I have a application that on a screen is a RadGridView that contains a GroupPanel. I would like to allow the users to export this grid to excel, but when I try to export I get an error converting the GroupPanel. I have tried to set the ShowGroupPanel to false during the export but that does not seem to help. IS there an export setting that would remove the GroupPanel?
