I was specifically looking for a winforms combobox with autosizing and I noticed (in your documentation) you support this. However it doesn't seem to be working. I'm not sure if it's because I'm using a databound datasource or exactly why. I want the combobox to automatically set it's width to the length of the text contained within it. I'm using version 6.1.0.0.

First drawing of ribbon bar command tabs

I have the following problem. Ribbon bar which contains more then one tab is being downsized and immediately upsized when I switch command tabs for the first time (i.e. it happens once for each command tab whe it is first selected and rendered). I'd like to avoid it as it's not very pleasant effect and when there are other complex controls on the form, it forces them to redraw twice.

Is there any way how to tell RibbonBar to maintain height on tab-switching? Or some other solution that'd halp me solve the problem? Thanks in advance.

Best regards,
Daniel

Wierd Color Issue

Lately I've been getting some wierd reactions inside Visual Studio 2005 and with my application. The RadRibbonBar is showing wrong color/theme for a few menu items and some click events aren't working on a dialog form I have. The only recent change I've made is updating to Q1 2008 WinControls, but I'm not sure that's the culprit.

I'm hoping someone here has seen this before and can help. I have attached an image to show the color issue.

On the image you can see that I just created a new chunk and added a radbuttonelement to it to show what the theme is supposed to look like (and used to), but next to it you can see the other chunks and buttons that are all wrong. I have not touched the design code or themes. It's using the ControlDefault theme.

Bug? Cutting and pasting a radTabStrip loses controls

I don't know if this is specific to my system, but any time I perform a cut-and-paste operation with a radTabStrip, the pasted radTabStrip loses all the controls that were in the tabs.

To test, add a radTabStrip to a form, create two tabs, then add some controls to each tab. Select the radTabStrip and perform a cut operation via Ctrl-X. Paste the radTabStrip back onto the form via Ctrl-V. The controls added to the tab pages are not present.

GridViewLookUpColumn remains in edit mode

Hi, I have a GridViewLookUpColumn placed in the last column of a row. I need to dynamically turn the grid's ReadOnly property on and off. So when I set ReadOnly = True, the combobox remains in edit mode. Has anyone seen this happen to them?

Regards,
David

One Little Bug With ColorDialog

Hi I was playing around with the radColorDialog today and I found a slight error. When the dialog is first opened, the default color is red. However, when the dialog is closed and then opened again, the selected color is null. If one clicks OK without selecting another color, it will generate a nullreferenceexception.

Thanks in advance for reading.

Weird behaviour with DataBinded RadComboBox

Hello!

I'm having a strange issue in my application. My scenario is as follows:

1. I have a simple form, with a RadComboBox and a TextBox;
2. I have a custom object (say myObject);
3. I bind my RadComboBox to a DataTable, using a BindingSource;
4. I had a binding to the RadComboBox from SelectedValue to a property of myObject;

The problem is that whenever I select an item from de RadComboBox (DropDownList mode), and then I leave the combo changing the focus elsewhere, the combo becomes unselected. I tried the same with the normal ComboBox and it works flawlessly.

Any thoughts on this one? Many thanks in advance!

My code, at Form Load:

    
            cmbTipoCriterioPai.BindingContext = new BindingContext(); 
        
            // Populating the BindingSource 
        
            ServicoTipoCriterio servicoTipoCriterio = new ServicoTipoCriterio(); 
        
            bsPais.DataSource = servicoTipoCriterio.GetDadosPesquisa("0=0"); 
        
            servicoTipoCriterio.Dispose(); 
        
            // DataBinding the RadComboBox 
        
            cmbTipoCriterioPai.DisplayMember = "Designacao"; 
        
            cmbTipoCriterioPai.ValueMember = "ID_TipoCriterio"; 
        
            cmbTipoCriterioPai.DataSource = bsPais; 
        
            // Adding the SelectedValue DataBinding 
        
            cmbTipoCriterioPai.DataBindings.Clear(); 
        
            cmbTipoCriterioPai.DataBindings.Add("SelectedValue", myObject, "ID_TipoCriterioPai");

Hierarchy from Custom Collection?

I know that you can bind the RadGridView to a DataSset and set the AutoGenerateHierarchyFromDataSet property to true in order for it to show the hierarchy of objects.
However, my grid is bound to a custom object collection which has nested collections and i need the same behaviour to be reproduced using it
