I have a RadGridView.  Binding to my data source takes about 30 seconds for 1000 items.  This is far too slow for me.  So I turned on virtualization.  This sped things up, but now I can't scroll without a 5 second delay per screen of items.  Now this is too slow for me.  So here's what I want:

Grid gets its items source and acts as if virtualization is on.  Stuff shows up instantly.
Once grid is displaying items, it starts a separate thread to load the containers for everything else.
After 30 seconds, the grid is done and fluid to navigate in.  BUT it still responded and showed some items instantly.

Possible?

After implementing Q2 SP1, any checkboxes or buttons that were in a popup container will no longer check/uncheck or trigger the Command of a button.
It can be as simple as:
<Popup>
    <Checkbox Content="Test" />
</Popup>
And the checkbox wont physically check anymore.

I change back to the non Service Pack version, and it works fine.

Any ideas?

I'm working with very large databases and filtering (and sorting) at the database server.  I'm using the RadGridView filtering and sorting but catching the events and triggering a requery at the database server after gathering the users filter and sort choices and converting them to SQL.

So far so good however I ran into a problem:
When a new filter is created I catch that in the grid's Filtered event and examine for distinct filters and field value filters and build accordingly.  The problem comes when a user *removes* the filter from a column as there is no event fired that I can see so there's no way I know of to trigger another query.

Ideally I wish the GridView just had an event that indicated it needed a refresh of it's data when a user filters or sorts or changes column order etc to support people like me who are not going to simply send a gigabyte of data directly to the grid to allow it to do the sorting and filtering itself.  That way I could just iterate the columns build my sort and filter all at once in one go and be done with it.

This doesn't appear to be supported however or I missed something (which seems likely, because who builds a grid with no support for filtering and sorting at the back end?) so if my approach is wrong I'd love to hear about it.  If not then how do I determine when the user has *removed* a filter from a column?

I am attempting to use shape files from the following source:

Shape File Source

• Select - States (and equivalent)
• Select - Georgia (tested files)

The exact files I tested were the files for Georgia (both 2010 and 2000)

I currently have an information layer defined by the name infoLayer and I am initializing the reader in the code behind (I also get the same error when setting up the information layer in the xaml):


When starting up the program I get the following error:


The above code works fine using shape files from the DynamicHeatMap example.

Hi.. I have a pie chart where the items label will always be cut off whenever it is too long. Any idea how can I fix it? Apart from this, I tried to style the SeriesItemLabel to have transparent background but after I had apply the style the ShowConnectors in spidermode doesn't work anymore. Below is the xaml code:

Hi,

Is there an easy way to change the treelistview scrollbar background when its 'mouseover' or 'clicked/scrolled'? I have tried it in Blend but couldn't find a TreeListView template to copy and edit (only RadGridView).

Thanks in advance,

Hey, I've implemented a DynamicLayer and it uses an indexed Spatial DB as its source. It's fast to grab shapes from the DB, its reasonably fast to convert them into Telerik map elements with a SqlGeospatialDataReader, however when it comes to the UI drawing them, its terribly slow...

I'm zoomed in really far, I don't let it render until zoom level 16. I have to believe the number of shapes I have to render on screen at a time is not too much more than your shape file examples. My shapes are most likely quite a bit more complex, but the performance is just so absolutely terrible. I have to believe I'm not doing it right. Your rendering of tiles is quite a bit faster than other comparable WPF map products, IMO, but rendering vectors, even small amounts of them, is just about the worst of any product out there. Please help. I need something that can do both reasonable well.

Thanks

Hi,

After upgrading from Q1 2011 to Q2 2011, I can no longer build my program.  I receive multiple errors that say "Set property, 'Telerik.Windows.Controls.LocalizationManger.ResourceKey' threw an exception."

The innerexception detail is: {"Object of type 'System.Windows.Setter' cannot be converted to type 'System.Windows.DependencyObject'."}

Any ideas what has changed in between the two versions that can cause this problem?
