GridViewRowInfo not available in 2010

We developed an App with Q3 2009 SP1 and recently upgraded to Q1 2010 Beta. The following line of code now produces an error:

If TypeOf (rgvEDs.CurrentRow) Is GridViewRowInfo Then ' Ensure we have a data row, not a group or header

Error: GridViewRowInfo is not defined

Any idea? I searched the Object Browser and the class doesn't seem to exist anymore?!

[Solved] RadDock with Desert Theme

Seems when you select the Desert Theme for RadDock for some reason the default document tab controls (like the X for close and the down pointing arrow for selecting a tab) are not visible. Furthermore, the control does not honor the desert theme properties displaying a blue color on the tab section. Any idea why is this happening? or how can one change the appearance of the RadDock control?

Thanks,

George

Custom grid editor

I'm currently evaluating your product.

In the grid we are currently using, we use custom editor. These editor are controls and user control that we created and that we are using everywhere in the application. We would like to be able to use these same control in the RadGridView, but we can only use RadElement.

Is there a way to use our company control as editor in grid?

Is there plan to make an interface ex: IRadElement, that will make us possible to use any of our control in the grid.

Thank you for your reply.

[Solved] RadComboBoxElement inside GridCellElement

Hello -

I am nesting a RadComboBoxElement under a GridCellElement (in my actual code, I'm nesting a larger element tree of which one of the elements happens to be a combo box, which is why I cannot use a GridViewComboBoxColumn). I've almost achieved the desired behavior. Here are the three remaining issues:

1) Why doesn't clicking on the combo box's arrow button cause the dropdown to open up? Is the grid somehow intercepting this event?

3) When the Tab key is pressed, the current grid cell gets updated, but the keyboard focus is not moved from one combo box to the next. Can you tell me how to make tab work properly?

2) Why doesn't clicking into the combo box's RadTextBoxElement cause the current grid row to be adjusted (note that clicking on the arrow button does adjust the current grid row)? I believe the answer may be that the textbox is intercepting the mouse click even though I set RadComboBoxElement.NotifyParentOnMouseInput to true. What is the suggested workaround?

Here is some simple code that reproduces the problem:

                            void grid_CellFormatting(object sender, CellFormattingEventArgs e)         
                    {         
                        if (e.CellElement.Children.Count == 0)         
                        {         
                            var element = new RadComboBoxElement();         
                            element.NotifyParentOnMouseInput = true;         
                            element.DataSource = new List<string>() { "First", "Second", "Third" };         
                            e.CellElement.Children.Add(element);         
                        }         
                    }         
                     
                    void Form1_Load(object sender, EventArgs e)         
                    {         
                        var grid = new RadGridView();         
                        Controls.Add(grid);         
                        grid.BeginInit();         
                        grid.EndInit();         
                        grid.CellFormatting += new CellFormattingEventHandler(grid_CellFormatting);         
                        grid.MasterGridViewTemplate.AutoGenerateColumns = false;         
                        grid.Columns.Add(new GridViewDataColumn() { HeaderText = "Header" });         
                        grid.DataSource = new List<int> { 1, 2, 3 };         
                    }         

Thanks,

How to programmatically choose which columns of a table to display?

I am converting an old program (c++ MFC/Rogue Wave) to C#/Telerik. The old program gives users the options of deciding which columns of a data table to display at run-time. For my audience, the Column Chooser mechanism is too complicated for them to you, plus they are already used to a set of checkbox specifications in the setup routine.

So how can I, during form load event, choose which columns to display while still enjoy the automatic CRUD actions performed by databinding?

[Solved] How to Implment Drawing Highlighting?

I have the free Audacity audio file editor program. When you load in an audio file, the program displays a waveform of the audio. You can mark an area on the waveform by clicking on the wave form with the cursor and draging the cursor horizontally. This causes the area you selected to have a darker background. It looks like a selected block. (See attached screenshot.)

Once you've done that, you can also position the cursor on either end of the block to drag that edge of the selected portion back and forth to resize the area.

I need to implement a similar feature in my own application, with the added requirement of being able to select more than one area on the waveform at one time.

Anyone have any ideas on how I might go about this using Telerik .NET forms controls? Maybe positioning some kind of partially transparent object over the waveform?

Thanks for any suggestions.
