I am dynamically adding RadPanelBarGroupElements to a RadPanelBar that is set to the Explorer style. Each RadPanelBarGroupElement's control panel contains a large usercontrol that is approx 700px in height. The first few added are displayed with scrollbars in the content panel when expanded which is fine. However as more RadPanelBarGroupElements are added, the bottom ones have a very tiny display space, while the RadPanelBarGroupElements at the top when expanded still display a relatively large viewing area.
Is there a way for me to specify the minimum space that must be displayed?

    
                    private void LoadApprovalIssue(ApprovalBe.ApprovalIssueRow issue) 
        
                    { 
        
                        ApprovalIssueControl issueControl = new ApprovalIssueControl(ref this.myActivity, approvalTypeCode, ref this.myApproval, issue.IssueNo); 
        
                        RadPanelBarGroupElement issueTab = new RadPanelBarGroupElement(); 
        
                        issueTab.Caption = "TEST";  
        
                        issueTab.EnableHostControlMode = true; 
        
                        issueTab.ContentPanel.Controls.Add(issueControl); 
        
                        issueTab.ContentPanel.AutoScroll = true; 
        
                        this.pnlbarIssues.Items.Insert(0,issueTab); 
        
                    }

Cell Sizing in Custom Cell

Hi,

I have a custom cell layout, similar to a Business Card, and it lays out exactly correctly. However I want to instruct the grid to obey a minimum size for the cell, but I cannot seem to get it right.

Heres my code from the custom GridDataCellElement - I wonder if you can spot the problem or sugges a better way of forcing a minumum cell size ?

Thanks.

columnGroupsView/HTMLView ??

I'm trying to evaluate which way to use the new grid layouts to achieve the layout I want and I have some questions.

1) is there a gui way of setting up the columnGroupsView through the property builder?
2) In the columnGroupsView is it possible to disable some of the column headers? Ex. specify a group header (Address) but not show the individual column headers (street, city, state, zip).
3) In the HTMLView is it possible to add a group column header?

Thanks,

GridView

Multiple carousels on one form

I've been playing with the demo version of the WinForm controls, anticipating using them for a future client. To implement their requirements, I foresee using multiple carousels on one main page. As I'm testing this, I haven't been able to get both carousels to autoloop. If I set EnableAutoLoop to True for both 'top' and 'bottom' carousels, the top will rotate while the bottom will not. If i set EnableAutoLoop to False for the 'top' and to True for the bottom, the bottom will autorotate while the top will not (as expected).

Is there some other setting I need to change?

Thanks!
Sheryl

Specific apparences for custom objects

I created a custom button that inherits from RadButton. I am able to inherit the theme of the RadButton by overriding the ThemeClassName like shown in your Knowledge Base. However, that's not what I want to do. Here is the override I have done :

class MathButton : RadButton{
    public override string ThemeClassName{
        get{return "WindowsApplication1.MathButton";}
    }
}

My theme gives an appearence to all the buttons of the RadButton type, but I don't want the MathButton to inherit the RadButton appearence. I would want to be able to have a different appearence for each type of button I create from the RadButton type. I want all the button appearences to be in the same theme.

Is there a way to do that?
