Customize Header with HtmlViewDefinition

I my application I have a need to basically merge 2 rows.
So I am using the HtmlViewDefinition to do so.
It all is working great but I want to remove some of the column headers as they are all kind of duplicate(by design) per the data.

The view istructured like this:

    
             HtmlViewDefinition view = new HtmlViewDefinition();  
        
                          view.RowTemplate.Rows.Add(new RowDefinition());  
        
                          view.RowTemplate.Rows.Add(new RowDefinition());  
        
                          view.RowTemplate.Rows[0].Cells.Add(new CellDefinition("Code_V1"));  
        
                          view.RowTemplate.Rows[0].Cells.Add(new CellDefinition("Name_V1"));  
        
                          view.RowTemplate.Rows[1].Cells.Add(new CellDefinition("Code_V2"));  
        
                          view.RowTemplate.Rows[1].Cells.Add(new CellDefinition("Name_V2"));  
        
                          this.gvMembers.ViewDefinition = view;

So the header basically looks like this:

Code_V1        Name_V1
Code_V2        Name_V2

But I want it to look like this:
Code        Name

So I would like to remove the second "row" of the header".
Or if that is not possible, can I make the height be smaller to basically hide the second row.
I am not usre how to do either.
Any ideas os suggestions would be appreciated..

Using RTL on Dock

hi,
in the product specs it is mentioned that it supports RTL:

Right-to-left Language and Localization Support

Due to business globalization, the need for multi-lingual applications is a must. Telerik WinForms Dock supports all RTL languages, such as Hebrew and Arabic. RadDock's window captions, drop-down menus and action buttons (close, pin/unpin, etc) are fully localizable through a simple and intuitive localization provider, or through resources.

I tried a few ways but couldn't make it work.
i need it to support hebrew.
I'm using Q2 2009.
please advice.

thanks,
Idan

"Copy" Option Visible & Enabled in ContextMenu but Does Nothing

There's a "Copy" Option that's Visible and Enabled in the default ContextMenu but it doesn't seem to do anything. If there's no default behavior when you select it, then it shouldn't be in the default ContextMenu at all. If users want a Copy option, they can customize / replace the ContextMenu.

I don't see any Event that might be triggered by it. If there's an Override-able Method it calls, as usual, it's doesn't seem to be documented.

FYI, I thought a good use for it would be to do the same thing that the following KB article implements for the Ctrl-C key (namely copying the CurrentRow's Cells, delimited by Tab's and terminated by a Line Feed, to the Clipboard). I overrode it's handler to do so.

Can the container automatically fill a form?

Can a split container be set to automatically fill a form's area or does it have to be done programatically?

Editing UI Elements Via:: Edit Ui Elemtents Smart Tag does not persist changes

Hi there,

this is my first post here, mainly because until now i have not had any real issues with the controls.

Controls in Use: Rad Controls For Win Forms, Q1 2008

For my current project i need several Split Button elements on the Ribbon bar.

Normally, not an issue. But Now i am trying to edit the visual Look of them via the 'Edit UI Elements'. Once i make the changes , the visual design is applied at design time. However, once i run my application the control reverts to a OuterInnerBorder state which is not what i am wanting. I want a SingleBorder persisted on the control.

This problem is with all instances of the Split button, and Drop Down Button elements for the Ribbon bar.

I am also editing the size of the Fill Primitives, these too are not persisting the changes i am making once i run my application.

Any one have any ideas as to why this may be???????

Thanks in advance for your replies.

Oh as a side not, the ribbon bar chunk is showing the same behaviors. I turn off Auto Size, and manually define them for some of the chunks (Trying to keep the height the same across all chunks and tabs. Width and height settings are not being maintained on the bar chunks)

Buttons, RadioButton, CheckBox, etc

Total row formatting

Hello,
I am using GridViewSummaryRowItem and i found it very useful so far. However I have problem with adding custom format (color, border) to the total row. In examples there is code snippet that uses cell formatting event to do so:

    
              if (e.CellElement is GridSummaryCellElement) 
        
                        { 
        
             //Set formatting... 
        
                        }

But my GridView doesn't fire either cellfromatting or rowformatting event for the total row, so I have no way how for example set custom background color. Here's my code to setup the total row:

    
                  GridViewSummaryRowItem sum = new GridViewSummaryRowItem(); 
        
                        sum.Add(new GridViewSummaryItem("CeleJmeno", "Celkem", GridAggregateFunction.None)); 
        
                        sum.Add(new GridViewSummaryItem("Preplatek", "{0:C}", GridAggregateFunction.Sum)); 
        
                        sum.Add(new GridViewSummaryItem("Zustatek", "{0:C}", GridAggregateFunction.Sum)); 
        
                        this.grdHromadnaVyplatnice.MasterGridViewTemplate.SummaryRowsBottom.Add(sum);

Add chart or any other control to a cell

What I wantto do is in the CellFormatting event(of elsewhere) I want to dynamically add a chart to a cell.
I can create the chart from code with no problem but I don't see a way to add a chart or any other control to a cell.
What I thought I would be able to do is this(pseudo):

GridCellElement cell = e.CellElement;

cell.Controls.Add(createChart(series1Val, series2Val));

Is there a way to add a chart to a grid and or a cell specifically?
Of if I need to do it at the column level(and use values from other columns) or any other level, please let me know..

Thanks

OnActivated is not getting called in Tabbed documents

Hi,
I am using a RadDock control with AutoDetectMDIChildren set to true. I have been given forms to be hosted as tabbed documents. I do this by setting the forms' MdiParent property to the main form and then calling their Show methods. These forms override the Form.OnActivated method. This method is never called.

Here is a simplified example:

    
                public partial class MdiChild : Form  
        
                {  
        
                    public MdiChild()  
        
                    {  
        
                        InitializeComponent();  
        
                    }  
        
                    int counter = 0;  
        
                    protected override void OnActivated(EventArgs e)  
        
                    {  
        
                        label1.Text = string.Format("Activated {0}", ++counter);  
        
                    }  
        
                }

When I first show the form I would expect its Label1 to display Activated 1. If I click on another tab then back on this form's tab I would expect to see Activated 2 etc.

Thanks
