Number of items stacked upon each other / overlapping items / required height

Is there any way to determine the number of items that have overlapping timespans and are therefore displayed vertically one below the other? To clarify, I'm interested in the maximum number of items in the whole timeline that are displayed below other items.

If there are too many items at the same time, the items happen to overlap each other (see attached screenshot, top image). I want to automatically adjust the height of the RadTimeline so that the items don't overlap anymore, but fit in the control without overlapping. (Actually I want to adjust the size of the TimelineItemContainer via a custom style, but what matters is that I get the needed height - the bottom image on the attached screenshot is what I'm trying to achieve with automatical height detection)

I guess the RadTimeline control knows that height internally anyway, because otherwise it wouldn't know how to layout the overlapping items when there isn't enough space. Is there any way to get the values I'm looking for?

Conditional Formatting dialog

Hi see that WinForms GridView has a beautiful Conditional Formatting dialog that let the user formatting the grid at runtime. I cannot find the same thing for the GridView for Wpf. Does it exist a prebuild dialog? or if not, what is the quicker pattern to create it?

Thanks in advance (and sorry for my english)

Loading animation when using VirtualQueryableCollectionView

Is there a way to instruct the RadGridView to display loading animation while it is fetching data from the bound VirtualQueryableCollectionView(query) { LoadSize = 10 }?

Probably not when scrolling, but when it's loading the initial data...

I have tried DataLoadMode="Asynchronous" but that doesn't seem to do the trick...

Binding Button to RadGridCommand

Hi,

I have been looking at the Command example in the wpf examples and I'm trying to bind a button click to a Grid Command

I have a RibbonBar and on the RibbonBar I have some navigation buttons (First,Last,Next,Previous)

I then have a RadTabControl with a few tab pages on I have a ContentTemplateSelector which depending on a value will add a RadGridView with set columns to the tab page.

it is this GridView i'm trying to add the bindings too.

Hope I have explained what i'm trying to do :)

thanks David

RadGridView: Filter not working

When I am using RadGridView in my xaml and have IsFilterable = "True" on the columns (GridViewDataColumn), I am able to see the filter icon for the required columns.

When I click on the filter icon on the column header, a nice filter drop down comes up.

However, when I try to filter based on any filter in "Show rows with value that" drop down options, the filter stops responding and does not collapse either. It's only when I click outside the application, the filter collapses (so the filter does not serve any purpose of filtering).

Any idea why this is happening, since I am don't have any custom code. Is this a bug in the control itself?

Axis Label Click Event?

Hello,

The ChartArea's ItemClick event works great, but I now have an issue where if the value is too small (in a BarSeriesDefinition) then the bar won't display at all and the user is unable to click on anything. In those cases where the value is too small to display a visual, is it possible to make it so that the user can at least click on the Axis label?

Regards,

Anthony

DataTemplate focus

I am using a NewItemTemplate and EditTemplate in my DataForm. When I go into Add mode, the focus seems to be one tab short of my first textbox. In Edit mode, it appears to be one short of the buttons on the top of the data form. How do I get the focus to be on that first textbox in the datatemplate. (My datatemplates contain a grid with a series of horizontal stack panels because of some formatting I needed to be able to do.) Is there a way of turning off the tabstops for the "extra" controls? Or setting the focus to the first box?

The examples that I can find in the forums are either finding the first dataform field or turning off the tab stop on some controls so you can get from the last textbox to the ok button (I couldn't get that one to work either).

thanks!
