I see posts from 2008 and 2009 about the masked edit box not supporting null values
(http://www.telerik.com/community/forums/winforms/maskededitbox/value-cannot-be-set-to-null.aspx)

Is this still true? It is a little misleading to see "0.0000" in a edit box when the real value is null.

In my situation, the mask type is "numeric" and the mask is "n4". The "nulltext" property doesn't seem to have any effect.

Is there any workaround to blanking the edit box when the value is null?

Change font of RadTreeView e.a.

Hi,

I am trying the do a few things and I don't seem to be able to do this with the WinForms RadTreeView control - or at least I don't know how:

1. Change the font. Seems simple, but I tried doing it in both the designer and in code (myTreeView.Font = new Font(...) etc), but no matter what I set it to, the treeview still shows the same font. What do I need to do to change this??

2. How to I remove/hide/decrease the left margin showing on all first level nodes? I am not using a root node and there's always a white margin to the left of each node.

Thanks!

"+" Button From Install Demos

Hi,

I'm looking to included the "+" button that is on the PageView demo under StripView > Add New Item but haven't had much luck trying to look through the included code or through the documentation on here.

Can some one please point me in the right direction so that I can have this add button on the end of my PageView?

Many thanks,

Guy

Indication of child row presence

Hi.

I use hierarchies a lot. Is there an easy way to indicate that a row actually has any child rows - e.g. "expander"-icon bolded or something like that. I'm aware that I can access ChildRows-property at GridViewInfo-level, but I'd rather keep it "inside" the gridview - perhaps using the expression builder.

Best regards,

Jeppe Havelund

DropDownList and item visibility broken?

Hi, I'm using the latest version of the WinControls package and I'm using trying to hide inactive data on a DropDownList to prevent the user from selecting it but ElementVisibility.Collapsed shows a blank line (as ElementVisibility.Hidden). It is my understanding that the row should not visible nor blank with the first value.

Am i missing something?

private void uxAssignedAt_VisualListItemFormatting(object sender, VisualItemFormattingEventArgs args)

{

var personne = args.VisualItem.Data.DataBoundItem as Personne;

// Reset default value

args.VisualItem.ResetValue(LightVisualElement.VisibilityProperty, ValueResetFlags.Local);

if (personne != null && !personne.IndActive)

{

args.VisualItem.Visibility = ElementVisibility.Collapsed;

}

Disable Right Click Selection Change

By default the tree view will change selection by clicking on a item with left or right mouse, I need to prevent the selected item from changing when a item is clicked with the right mouse, instead i need to hilight the item and pop a context menu.
Also where do you change the color of the selected background?
Thanks

Winform treeview questions

Hi all, i have questions about treeview in winform. Is it possible to integrate or combine explorer-like treeview to telerik treeview? I mean when the root folder/node is set to desktop directory, then it would auto generate all the childs and other nodes (which is folders/shortcut) inside the desktop.. Another question is how to make drag n drop function that copy the folder/node and not move it to the other treeview?

Sorry if I ask many questions here, I am a lil' bit beginner to this thing and hope you all can guide me. Thanx for your coorperation.

Regards,

Muz
