Date and Time on Xaxis?

Is it possible to label the xaxis w/date and time?

i see
.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;
and
.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortTime;

I have hourly-ish data over several-ish days...

Streaming ticker data

Hi Telerik team,

We are evaluating your gridview capability to see if you can stream data onto grid without grid hanging or using up lot of memory. We are looking at update rates of around 10,000 quotes per second. Can you let us know your gridview has the capability to do so and if so can you point me to some examples. I would like to evaluate your grid and if it fits our needs we can plan to buy the product.

Thanks

RadHostItem does'nt work in my ribbonBarGroup

I want to add some winform controls in my ribbonbargroup using the RadHostItem. I follow some tips found on this forum but they don't work for me. My ribbonBarGroup is empty

Here is my code :

                    Dim Foo As New TextBox         
            Foo.Text = "Bar"         
            Dim hostItem As New RadHostItem(toto)         
            MyRibbonBarGroup.Items.Add(hostItem)         

So, I though that the proble came from the add method. I tried the same code replacing the hostItem by a RadButtonElement control and it worked fine.

That's why I think the problem comes from the radHostItem.

Image and ToolWindow

Hi,

I cannot figure out how to display an image on the ToolWindow tab. This does not display the image on the tool window :

Horizontal Auto Scrolling Behavior on Cell Click

Hello,

I have several custom width columns in my RadGrid and when I click in a cell that is partially displayed the grid horizontally auto scrolls to bring the entire column into view. This functionality is great in most cases but when the column contains buttons it causes undesired results.

IE: Cell contains several buttons but the entire cell isn’t visible within the grid. When the user clicks the first button the grid auto scrolls, bringing the column into view, but the button click event that fires is for one of the hidden buttons instead of the button clicked. We think this is happening because the auto scrolling fires before the click event and since the mouse cursor in now on a new button after the scrolling it fires that event instead of first clicked button.

One of two solutions will work for me.

1. Either suppress the auto horizontal scrolling so the column doesn’t shift into view.

Or

2. Make sure the proper button click event fires.

How do I make either of these happen?

Regards,
Mike

Hiding chart border

I am trying to setup the charts so that only the plot area is shown and the chart has no border. I can't seem to find the correct border property. There is a border property on the chart object itself that is set to false. Is the chart border coming from the skin?

Thank you.

Best data binding strategy?

I’m developing a c# win app using RadGrid. I would preferably like to be able to use the grid property builder in design time to configure columns, dropdowns etc. On the other hand I would like to work with business objects (using EntitySpaces or similar) to access the data in SQL Server and later implement remoting or similar technologies to migrate to a true n-tier client server app. Anyone having some suggestion regarding an architecture that makes it quick and easy to build the app using RadGrids, but enough ‘future safe’ and object oriented to work in a business application?

Could Microsoft entity framework and Linq to Objects be the solution?

Regards,

Erik
