[Solved] How to enable row borders

Hello, Telerik Team.

I have two questions.

1.
I'm using default Telerik theme:

    
            this.ThemeClassName = "Telerik.WinControls.UI.RadGridView";  
        
            this.ThemeName = "ControlDefault";

And now I should implement lines between rows. I tryed solve this with next code:

    
                    void _gridView_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)  
        
                    {  
        
                        GridDataCellElement cell = e.CellElement as GridDataCellElement;  
        
                        cell.DrawBorder = true;  
        
                        e.CellElement.BorderTopWidth = 1;  
        
                        e.CellElement.BorderTopColor = Color.LightGray;  
        
                    }

But in this way the last column has black borders.

May be I did anything wrong? How can I enable borders for rows in easy way?

2. I'm using my grid with enabled EnableHotTracking property.

[Solved] Help with waiting bar in radgridview

Hi, im trying to use waiting bars inside radgridview, I sucessfully add the waitingbars to the gridview in the CellFormatting event.
The problems comes when i try to dinamically change the state of the waitingbars individually (startwaiting - stopwaiting) when certain event happend eg. when i click a button i want determined cell to starwaiting or stopwaiting, here is the button code:

private void NewPjButton_Click(object sender, EventArgs e)

{

radGridView1.EndEdit();

radGridView1.Rows[2].Cells[5].IsSelected = true;

radGridView1.Rows[2].Cells[5].BeginEdit();

RadwaitingBarEditor editor = radGridView1.ActiveEditor as RadwaitingBarEditor;

if (editor != null) //this is always null

{

RadwaitingBarEditorElement element = editor.EditorElement as RadwaitingBarEditorElement;

element.StartWaiting();

}

and here the editor and element editor:

public class RadwaitingBarEditor : BaseGridEditor

{

public override void BeginEdit()

{

base.BeginEdit();

this.EditorElement.Focus();

((RadwaitingBarEditorElement)this.EditorElement).WaitingStarted += new EventHandler(RadwaitingBarEditor_WaitingStarted);

}

public override bool EndEdit()

{

((RadwaitingBarEditorElement)this.EditorElement).WaitingStarted -= new EventHandler(RadwaitingBarEditor_WaitingStarted);

return base.EndEdit();

}

void RadwaitingBarEditor_WaitingStarted(object sender, EventArgs e)

{

OnValueChanged();

}

protected override RadElement CreateEditorElement()

{

return new RadwaitingBarEditorElement();

}

public class RadwaitingBarEditorElement : RadWaitingBarElement

{

public RadwaitingBarEditorElement()

{

this.CanFocus = true;

}

public event EventHandler WaitingStarted;

protected override Type ThemeEffectiveType

{

get

{

return typeof(RadWaitingBarElement);

}

protected override void OnPropertyChanged(RadPropertyChangedEventArgs e)

{

base.OnPropertyChanged(e);

if (e.Property == RadTrackBarItem.ValueProperty

&& this.Parent != null

&& this.WaitingStarted != null)

{

this.WaitingStarted(this, EventArgs.Empty);

}

this code just dosent work, the editor is always null. Please if someone can guide me how to do it correctly I will apreciate it so much!!.

Thank you,

GridView

AllowRemove some and not others

Hello,

I need to find a way to intercept an event, key press, or something. I need to be able delete some nodes in a RadTreeView, but not others. Some nodes are parent "static" nodes (i.e. node analogs to a List<Object>), whereas other nodes are non-static, the Object values themselves.

I'd like to delete the non-static children, and not delete the static ones, during normal "casual" operation. That is, the user is navigating and casually pressed Delete to delete a node.

The poor man's way of doing it will probably work: hook up some context menus, that sort of thing.

Is there a BeforeRemove type event, or otherwise an event that allows me to check and flag a Cancel?

Thank you...

ExplorerBar - Change item attributes

I'm using the PageView in ExplorerBar ViewMode. I would like to change all of my PageViewPages so that:

1. The item height is smaller (shorter).

2. Mouseover doesn't change the item color.

3. Select/Deselect doesn't change the item color.

4. I'm going to set up two images to use to indicate whether the user can expand or collapse a page. I think I can manage that much. But if you have any suggestions, especially for pushing the image over to the right side, I would be happy to read them.

Thank you.
