How would you get the ContentPanel of the currently selected tab? I've seen one example in the forums where the RadTabStrip control collection is used, but I only need to get the ContentPanel for the currently selected tab.

Can you get the object out of a bound Rad collection control

Hello,

I hope that someone can help me with an issue related to binding a bindable collection class to one of the Winforms Telerik list controls.

If you bind to a plain ole windows list control like this...

    dim list as new comboBox

    with list
        .DataSource=myCollectionClass 'this contains a collection of widgets.
        .ValueMember="WidgetID"
        .DisplayMember="WidgetName"
    end with

I can then get a widget out of the list by doing this...

    Dim myWidget as Widget=ctype(list.Items(0),Widget)

If you do the exact same code with for example a Telerik RadListBox (same example as above)
but change line one to be

    Dim list as new RadComboBox.

With RadControls it seems you cannot cast to the Object type directly. Whenever I try this I get the following error...

    Unable to cast object of type 'Telerik.WinControls.UI.RadListBoxItem'
    to type 'Widget'.

Can someone at the least confirm that this is a known limitation of Telerik RadControls for Winforms or let me know the proper way to do it.

Thanks.

Can't remove margins from charts

Hello,

I have been able to get most of my required chart layout customizations to work. The only thing I can't figure out is how to get rid of the left and right margins in the plotted data and the right margin between the right side of the plot area and right side of the chart. I tried messing with the margins in the plot area > appearance > dimension area but it didn't work. I would set all the margins to 0 and they would come back. I would also set autosize to false, but this causes major exceptions in the designer. I also tried messing with the autosizing in the plot area > appearance > position area but this also causes major exceptions in the designer. I just want my chart to look normal with the plotted data taking up the full widh of the plot area and no margin to the right. This should really be the default layout. Is it possible to achieve this in the RAD charts? Is this something that is being worked on?

Thanks,

-Brian

This row has been removed from a table and does not have any data.

I am just getting started with using the win forms controls rad grid view. I am using linq DataContext class as the basis of my binding source. This loads the rad grid fine but when i select a row i come up with this error. "This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row." This shows up in the Applicationrun in my Program.cs file. I was using the standard win forms controls and have no problem with selecting rows. I have looked at the online help but have only seen a couple of instances that i thought would work but nothing yet has proven true. Any ideas as to what properties or actions i need to take.

Thanks john.

QuickStart documentation is slightly misleading

To whom it may concern,

As I was reading the QuickStart documentation of RibbonBar, I noticed that it tells you to inherit your form from ShapedForm instead of RadRibbonForm.

Although it's not a big deal, I think it would be nice to update the documentation and reflect the current best practice of RibbonBar usage. :)

Thanks in advance.

Conditional formatting issue

Hi,

I have a grid view and want a date column to be conditionally formatted. It works using the code shown below however the header cell for that column also gets formatted. How do I prevent only the data getting formatted. Code follows.

            Dim amberFormatting As New Telerik.WinControls.UI.ConditionalFormattingObject("Amber", Telerik.WinControls.UI.ConditionTypes.LessOrEqual, Now(), "", False)  
        
            amberFormatting.CellBackColor = Color.FromArgb(255, 209, 140)  
        
            uxRadGridView.Columns("Due").ConditionalFormattingObjectList.Add(amberFormatting)
