Hi,

I want to achieve a radgrid view with nested collection. The twist is binding should create a new column and not like row details.

E.g. My data looks like

List<class1> lstObj1 = new List<class1>();

public class1

{

public string name;

public string id;

public List<class2> objClass2List = new List<class2>();

}

public class2

{

public string sub1;

public string sub2;

}

View should be like as attached:

Hi, I've got a situation where I need a chart to create a new line series based on user selection (i.e., user selects 3 Employees from a list of 10 to compare, and then the chart will show 3 Line series, each corresponding to the respective employee's annual revenue to date). 

Most of the examples rely on code-behind to create a new SeriesMapping and then add it to the chart's list of mappings. I'm curious if there would be any declarative way to account for a varying number of Series on a chart, similar to a DataTemplate used for other controls. To bind the number of Series to a collection where each Series binds to a sub-collection.

Here's a grid I have working for just one series:

I have some functionality that I would like to have included in every instance of RadGridView in my application. This is on two events, DistinctValuesLoading and FilterOperatorsLoading.

I tried adding them via EventSetters in a global Style ResourceDictionary, but I'm getting error saying that they are not Routed Events.

Is  there another way to do this, or do I need to just add the functionality manually to every instance?

I have a setup that each row detail contains a child gridview, and when parent row is expanded, the child gridview should show all its rows, ie. no scrollbar because we don't want "double" scrollbars.

The issue is when the child gridview has many rows (in our case, 100), it takes a while (~6s) from expand the parent row to display all children rows.

Do you have any tips to speed up this scenario?

I have a RadGridView with ItemsSource bound to a collection of business objects.  The grid has a GridViewDataColumn bound to a property with a TwoWay binding.  The property has a validation attribute.

When the user is editing the cell, and presses <Enter>, the validation attribute's IsValid() method is invoked, and if validation succeeds, the griid navigates to the same column in the next row.  But if validation fails, the failure is visualized and the navigation does not occur.  In fact, any attempt to navigate away from the cell by any means causes validation, and if the validation fails, the navigation does not occur.  This is all good, and exactly as it should be.  Anything less would be wrong -- what's the point of validation if it doesn't force the user to enter valid data?

But here's my problem.  I also want the down and up arrows to navigate up and down while editing.  Seems as if it should be straight forward -- just preview KeyDown, handle up and down keys and execute the grid's MoveUp and MoveDown commands, right?  Wrong.  When the grid's MoveUp or MoveDown command is executed, the validation attribute's IsValid() method is still invoked, but a failed validation does not prevent the navigation.

This seems like such a routine requirement that I feel like I must be missing something.  The reason for the existence of the MoveUp, MoveDown, etc., commands seems to be the recognition that navigation controls might need to be more robust that the default behaviors.  But those command circumventing validation appears to make them useless.  Surely I'm just missing something.

Hi,

since we don't need the TimeRuler of the WeekView in our project, I've hid it and set the Minor/MajorTickLengthes to "1day", so all appointments of that day appear in one big cell.

Problem is, that - since the appointments happen at the "same time", they appear next to- instead of below each other.

When I activate the AllDayArea, my Appointments show up below each other but I still have the big - formerly TimeRuler - area, which I can't get rid of.

Any Ideas?

Thanks

I have an issue using the RadialMenu with the GridView.

If I use the following code : 

I will have a NullReferenceException with the following stacktrace if I scroll down and backward two time :

This is obviously caused by virtualisation.

I tried to set the RadialMenu as ContextMenu directly in the RadGridView managing the ItemsSource of the RadialMenu with the selecteditem of the RadGridView but I have another issue where the RadialMenu will show and hide if the show event occure while the selected row change.
