Is it possibly to suppress the 0.00 value and show just a empty cell.

That's because i've a grid with lot of currency values and it's mostly better just to see cells with values != 0.

 

RadGridView1.Columns.Add(New GridViewDecimalColumn("Currency"))  
RadGridView1.Columns(0).FormatString = "{0:C}"

Greetings,

I'm using a RadListview as a sequential timeline, so I want to make it look like a linear timeline.

I've written these lines to make sure that only horizontal scrolling is allowed (also did some changes via Smart Tag) :

Timeline.VerticalScrollState = ScrollState.AlwaysHide
Timeline.HorizontalScrollState = ScrollState.AlwaysShow
Timeline.VerticalScroll.Enabled = False
Timeline.VerticalScroll.Visible = True
Timeline.HorizontalScroll.Enabled = True
Timeline.HorizontalScroll.Visible = True

 

But no success! It still looks like it vertically adds items. Check out the gif I've attached.

I want to bind custom list of object to Tree view. Also want group the elements on some properties. Is there any way to add/create group in Treeview ?

for Example: 
i have List of class C1 that has Books, Authors, Title. I want to group the item first by Books, then Authors and then title, so Authors should be child of books and title should be child of Authors.

Please reply me.

regards,
Huzaifa

Could you, please help me to find code examples how to format numeric and datetime fields(columns) in RadGridView .

We need comma separator for numeric fields in RadGridView columns.

We also need short datetime format for datetime fields in RadGridView.

The problem is that we adding dynamically all columns from the c# code.

So we have to format columns on a fly.

Hello,

I'm looking at some Telerik code that was written by another engineer who worked on our Telerik code maybe a year or two ago. He had built 12 or so Telerik WinControls and all of them -- except one -- are Telerik.WinControls.UI.Docking.ToolWindow (s).

For the one that isn't a ToolWindow, the WinControl is a Telerik.WinControls.UI.Docking.DocumentWindow.

From a quick google search, it appears the ToolWindow and the DocumentWindow work in essentially the same way, but what I am observing is that the DocumentWindow control doesn't re-create itself if that control was closed on the previous run of our application. All of the ToolWindow controls DO re-create themselves if closed on the previous run of our application.

Further, there is a dock.xml file that gets created at the conclusion of running our application. It appears all the ToolWindow controls get saved into that file, but the DocumentWindow control does not. Unsure if this is due to bad code on our side, or just intended behavior (haven't dug deep into this).

...

To state one specific question: Is it safe to just change the one DocumentWindow to a ToolWindow?
