Hi,

I am using RadAutocompletebox in scrollable size window. Window has vertical scroll and autocompletebox is at center of window. I have typed a text in completebox and suggestion popup appears and my mouse is on textbox area.Now, I have used mouse wheel event. When i use mouse wheel, popup scroll accordingly to up and down.

My concern is that popup should remain at one place but window can scroll accordingly.

Hi,

So when using an application like SQL Server Management Studio I can run a query (let's say select * from customer although my queries are very user driven with a few joins mostly the SQL is generated dynamically) and the results grid will start populating rows extremely quickly until the full set is returned.

I want to emulate this behavior using a RadGridView (WPF)

I have tried using a data set it takes to long and you don't get that initial feedback of seeing the first rows start flooding in.

Next I tried loading the customers from a data reader and putting each row into an ObservableCollection<Customer> it is way faster and allows the objects in .Net to start being populated even before the query has finished but ultimately the UI was unable to keep up with the reader and froze until the full set was populated.

What would be the best approach to get that fast response of data loading and the user seeing the rows start to appear without locking down the UI Thread of the application?

A typical result set is around 100k records and I can put it in the grid in about 5 seconds using a dataset im hoping to get similar time while showing the user immediate feedback their query is getting results

Hello Telerik,

We came across a scenario which we need to add a tooltip containing a UserControl to a tooltip of a grid's cell.

Can you please point me to the right direction?

Thank you

I always see CategoricalAxis being used on the X-Axis, however, I would like to plot multiple series based on Categories on the Y-Axis and have DateTime on the X-Axis.

How would I go about plotting:

var points = new ObservaleCollection<MyPoint>()

{

  (new MyPoint(){ Category = "ID1", Time = now }),

  (new MyPoint(){ Category = "ID2", Time = now }),

  (new MyPoint(){ Category = "ID3", Time = now + 1 }),

  (new MyPoint(){ Category = "ID1", Time = now + 1 }),

  (new MyPoint(){ Category = "ID2", Time = now + 2 }),

  etc, etc

};

I attached an image that shows what I'm trying to accomplish.

Hi,

I have a gridview that I have marked as readonly because I *only* want the user to be able to edit/add data via my rowdetails editor. According to the doc if I have the gridview marked as readonly they can't add a new row. I'm stuck. I need a way to add a row and have the user enter the new info via the rowdetails datattemplated editor. Any ideas?

Thanks ... Ed
