[Solved] Wrap Text in a RadAutoComplete

We are having an issue where the results are wider than the available area on the RadAutoCompleteBox. If it is too wide, it adds the ellipses (...). We would prefer it wrap. I tried programmatically setting the radAutoCompleteBox.ListItem.TextWrap to true, but there was no effect. How can I make the text in the drop down wrap?

[Solved] Deployment - TypeConverter not found

Hi

We build Telerik assemblies from source code using OemAssemblyName as per instructions at http://www.telerik.com/help/winforms/installation-deployment-and-distribution-redestributing-telerik-radcontrols-for-windows.html.

With 2015 Q1 SP1 (2015.1.331.40) built in Release40 configuration we are experiencing a strange issue when our application is installed on client machines. When one particular form is opened we get a series of nine pop-up 'TypeConverter' messages (please see the attached doc which shows the first four) before the form displays.

Apologies for the vague question but I was hoping you might be able to advise what might cause this issue? We haven't experienced it with previous releases where we've also built assemblies from source.

It kind of suggests that we're missing a dependency or have an incorrect reference in our build but I've double-checked and all appears to be fine there.

I'm struggling to found out why it's only the one form and if it's any particular control - otherwise I'd try to put together a test case.

As a workaround I have commented out the "Can't find TypeConverter from string for property ..." source code line in ..\RadControl\TPF\Theming\OLD\TSSP\XmlPropertySetting.cs but I'd rather address the real cause of the problem.

If it helps, the Telerik assemblies which we deploy with our application are:

Telerik.WinControls.dll

Telerik.WinControls.GridView.dll

Telerik.WinControls.RadDock.dll

Telerik.WinControls.Scheduler.dll

Telerik.WinControls.Themes.HighContrastBlack.dll

Telerik.WinControls.UI.dll

TelerikCommon.dll

TelerikData.dll

Again, apologies for the vague question with little supportive information but any ideas you have would be greatly appreciated.

Many thanks

Adrian

Upgrade WinControls 2010 to 2015

Hi

I have a legacy project that implemented with WinControls 2010. Now I should upgrade it to 2015 version (because it has problems with .net 4.5)

TabStripControl and other obsolete controls used in that project. So how can I upgrade them to new controls.

I managed to get 2011 version and upgrdae controls to that version and then use newer versions but there is no 2011 version available.

So how could I upgrade the project?

Mouse scrollwheel changes RadDropdownList even when you click away

Hi,

If you have a RadDropdownList on a form at run-time and the user clicks on it, and then decides to click on the form itself (not another control) the mousewheel can still be used to change the RadDropdownList contents.

This seems like it could lead to accidental changes to the RadDropdownList's contents.

Is this by design? Is there a simple way to prevent this behavior?

Thanks,

-Lou

DropDownList with datasource, not working as expected

Hello,

I try to use DropDownList with datasource, but is not working as expected.

When I Clear() the BindingSource, the RAD component still have "Text" with last item displayed which is abnormal.

Please see the code, the normal windows ComboBox works as expected.

Any fixes?

public partial class Form1 : Form

{

List<string> list = new List<string>();

BindingSource bsource = new BindingSource();

public Form1()

{

InitializeComponent();

bsource.DataSource = list;

}

private void Form1_Load(object sender, EventArgs e)

{

//Set list dataSource

comboBox1.DataSource = bsource;

radDropDownList1.DataSource = bsource;

//Now add an element via Binding object

bsource.Add("One");

bsource.Add("Two");

}

private void button1_Click(object sender, EventArgs e)

{

bsource.Add("Three");

}

private void button2_Click(object sender, EventArgs e)

{

bsource.Clear();

}

I need to this features because I can't link this control directly to my database, then I need to know when user change period range that he see.

Is it possible?

In WPF and Silverlight I used VisibleRange event.

[Solved] Buttons can be clicked with middle or right click

We've run into some situations where a right click on a particular Telerik control behaves in the way we expect only a left click to behave.

For example, we have a Command Bar with a bunch of buttons. If you right click one of the buttons, the Click event occurs and our application ends up doing the logic associated with the button. End users are confused because they don't expect a right-click to trigger a button click. The same goes for the middle click. It seems like the buttons in a command bar should only raise the Click event if they are clicked with the left mouse (assuming right-handed mouse). I'm not sure if the command bar supports keyboard navigation....but if so, then pressing the spacebar with the button focused should also trigger the Click event.

For normal buttons, this seems to work as I expect (right or middle click does nothing, spacebar triggers click event, etc.). I also found this old forum thread that talked about similar issues that I think have been fixed: http://www.telerik.com/forums/you-can-right-click-to-click-button

There are two other places where I've noticed right click works and I think those are bugs as well.

1. Checkboxes can be checked/unchecked by right/middle clicking on them (or clicking on the label). That seems wrong to me. The checkboxes inside of tree views also have this problem. However, checkboxes inside grids don't seem to have this problem.

2. I can open dropdowns by right/middle clicking the little down arrow on the right edge of the dropdown. That seems wrong.

Finally, I've noticed that buttons show the 'clicked' state on mouse down of the middle button. That doesn't seem right although I'm not 100% about that. The mouse down state also appears for right click if I right click enough time. This happens even on regular buttons.

Hopefully my explanations of the various issues I'm seeing make sense. I can see all of these problems in the demos included with the installation so I don't think any of them are issues with my code.
