Hi all,

I have a problem checking all checkbox columns in a grid. I used the next code:

Me.mygrid.GridElement.BeginUpdate()
For Each row As Telerik.WinControls.UI.GridViewRowInfo In Me.mygrid.Rows
row.Cells("Checked").Value = True
Next row
Me.mygrid.GridElement.EndUpdate()

It works well, but if the grid is sorted by some column the same code is so slow...

The datatable contains about 15.000 items. is that the problem?

Transparency of Dock

Hi,

I'm using Q2 2009 SP1. I want to be able to set my RadDock background to Transparent so that the BackgroundImage of the host Form can show through it. I have used the sample code elsewhere in the thread to do this;

    
            this.radDock1.MainDocumentContainer.BackColor = Color.Transparent;  
        
                        Telerik.WinControls.RadElement el = this.radDock1.MainDocumentContainer.RootElement.Children[0].Children[0];  
        
                        (el as Telerik.WinControls.Primitives.FillPrimitive).BackColor = this.BackColor;

but I have a couple of problems with this;
1) It picks up the BackColor of the Form but isn't truly transparent (the form's Background Image does not show through). I've tried placing a Picture box with the image on the Form, docked, and at the back of the Z Order, but again the Dock picks up the backcolour of the form, not the graphic immediately behind it.
2) I want to be able to set the individual DocumentWindow items in the RadDock so that they gradually "fade out" - the tabs being fully opaque and gradually fading to transparent until by the time they get to the bottom they are fully transparent. The reason for this is that the Dock and TabStrip is quite an "intrusive" control and seems (to me) to dominate the user interface once its been put there - I'd like to be able to make it blend into the background once the important bit (the actual tabs) are visible to the user.

Can you help ?

AppointmentEditDialog - show without using context menu

Hi,

I wonder if it is possible to show the editappointment dialog programatically, i.e. not via the built-in context menu?

The dialog should show based on the selection in the scheduler, i.e. the same way as the context menu command does.

The reason why I'm asking is that I want to show the dialog through a separate toolbar command.

Thanks in advance,
Johan

RadCheckBox

Hello,

I've seen a number of posts that explain how to highlight buttons, combos, etc using the Enter and Leave events.

I would like to do the same thing with the RadCheckBox. I've tried changing the BackColor of the ButtonElement, TextElement, etc but with no luck.

How do I accomplish this ?

Thanks,
Chet

[Solved] Get Default Text for GirdViewCommandColumn

I have 3 GridViewCommandColumn in my radGridView. I need to determine which one of the three command columns were pressed. I can't seem to figure out how to get the "Default Text" value to determine which command column was clicked. I can get the value of the command column by the CommandCellClick event but I can not get the "Default Text" value. My three default text values of the three command columns are "Time Sheet", "Print Monthly", and "Registration". Thanks for any help you can provide. New at WinForms!

Private Sub RadGridView1_CommandCellClick(sender As Object, e As System.EventArgs) Handles RadGridView1.CommandCellClick

Dim gcce As GridCommandCellElement = TryCast(sender, GridCommandCellElement)

'GridViewCommandColumn

If gcce Is Nothing OrElse gcce.Value Is Nothing Then

Return

End If

MessageBox.Show(gcce.Value.ToString())

End Sub

[Solved] Radgridview looses formatting in VS2010 Frwk 2.0?

I'm trying to do a capacity Load program and I've noticed that sometimes Telerik controls are loosing their formatting in VS2010. Is this is a common issue? I dragged the datagridview to the radfrom and i dont see anythin with the default formatting. I've tried to change the Themes and still doesnt work. It has happened couple of times already and removing the telerik software and reinstalling it dont fix the issue. Now I opened other apps and add the gridview and it works fine. I've attached a pic for your review.

Thank you
Jose

Three State checkboxes and events

Hello!
I am working on an application that uses grid view with checkboxes. When checkbox value is changed, it calls ValueChanged event with radGridView.EndEdit() and then calls CellValueChanged to read new data.

I want to expand checkboxes functionality with Three State mode however I want user only to be able to switch between normal On and Off states, while the Indeterminate state can only be assigned from the code. I want to make it so user can either go On -> Off, On -> Off or Indeterminate -> Off, and not On -> Indeterminate .

The thing is, I can't find a right event, that should be called when checkbox value is changed and change it, so user cannot reach null state by clicking it. Normally, in Three State mode, when user clicks on checkbox in On state, Indeterminate state is called. I want to switch this state to Off before reading the data.

I hope I've explained my problem clearly enough. Thank you for reading my post :)
