I have a WPF radgridview with the first column being GridViewCheckBoxColumn. I have templated the header

When the user click on the checkbox in the header i want to udpate all checkboxes in the rows to checked or unchecked. I am trying to do that with this code by "cb is always nothing". Pls advise

I noticed in your watermark example, any change isn't saved on the undo stack.

Is there a way on a custom tool you can programmically add to the undo stack?

Thanks

I am new to the WPF RadGridView and have a simple question.   I need to implement a search which looks at all columns of all rows in a bound, virtualized,  WPF RadDataGrid.   After discovering that the "ChildrenOfType<GridViewRow>()" function only returns a list of visible rows,  I searched this forum for an appropriate technique.  

I say one technique involving the RadGridView's "Records" property.   The current RadGridView does not have a "Records" property.

I also saw a couple of hits recommending searching the underlying bound data source instead of searching the actual grid rows.   That's easy enough.

But once I find the desired row in the underlying bound data (in this case an ObservableCollection<T>), how do I determine the matching grid row - and move it into the visible set on the user's screen - in a way that still works if the grid is sorted in a different order from the underlying bound data source?  

Thanks!

I have a radgridview displaying in the rowdetail of another radgridview. a list of sublists. this works nicely. now i want to make sure that the columns of the sublists are all synchronised. to do this, i was thinking of registering the loaded inner lists and using the changing/changed events of the columns. I am currently still having difficulties, finding the right information within the events (changed column number, current width), but I am more concerned about other issues. how are these rowdetails handled, are they unloaded when closed? I guess i should then unregister the detail. what happens when scrolled out of visible area? as the radgridcontrol can handle a large amount of data, i can imagine i must take a few things into account i have not yet thought about.

<radgridview>
<RadGridView.RowDetailsTemplate>
<DataTemplate>
<radgridview ColumnWidthChanging="gridView_ColumnWidthChanging"
ColumnWidthChanged="gridView_ColumnWidthChanged"
Loaded="gridView_Loaded"/>
</DataTemplate>
</RadGridView.RowDetailsTemplate>
</radgridview>

I am fairly new to wpf and very new to the radcontrols, so be kind ;) ...

Is there a way to fire the cellvalidating event when the cell is changed, instead of when it is commited? I want to validate after each character that the user enters into a cell. I thought setting to property changed instead of focus lossed would do it, but then the property is not really changed until it is commited is it..

Thanks!

I would just like to know how many levels I can drill down to in a chart. I read something about a bug that only lets you define and use 2 or 3 objects of type ChartHierarchicalViewDescriptor, but that seems like it would only apply if you had a different data structure at each level of the drill down.

I'm binding a chart to data built from an self-join in a database, so each level is the same as the previous. Will I be able to create one ChartHierarchicalViewDescriptor that works for as many levels as I have?

Thanks!

Hi guys i'd like to know on how to add empty cells at the bottom of the grid where the the user can add. It could be textbox or combo box. THanks!

I am testing the demo version of the GridView control (Q2 2011 version) and by integrating it into my current project. I am running into an issue though, because my current implementation makes heavy use of TypeConverters to display data in WPF controls. To help explain my question, lets assume a couple of things:

First, we have a generic superclass called Super, which has a property that is an ObservableCollection<Super> which is called Stuff. 

In another assembly, we have some generated code that defines subclasses of Super, each with their own set of properties. Some of the properties of this subclass have custom type converters also defined in the same file (these type converters are automatically generated). For example:

I abbreviated some of the methods but assume that they convert Int64s to Strings and vice-versa.

In addition, these subclasses fill the Stuff collection with some elements. Now, in my application we only refer to these subclasses by loading the assembly programmatically and using reflection.

When we pop up a GridView and bind it to the Stuff collection like so: 
We get what we wanted to see, all the properties of the subclass are reflected on and columns are automatically generated for them. We can edit them and ones that were not Browsable don't show up, ones that are ReadOnly can't be edited, etc. The only downside is that our custom type converters do not appear to work, and in fact it seems that they are never called by the GridView. We know that the TypeConverter code does work, as we have used them with other WPF controls for quite some time now without issue.

We are willing to change the way we define our TypeConverters if necessary (given that the WPF PropertyGrid that you provide would also support the TypeConverters given the same change), but we can not feasibly change to using IValueConverters, as that only provides us with ConvertTo and ConvertFrom methods, and what we really want is to be able to use the StandardValuesCollection (or something similar) that TypeConverter provides us, to avoid writing a lot of extra code in order to handle this conversion ourselves.

I saw a thread that somewhat pertained to this issue here, which claimed that TypeConverter support was added in the latest release but the author never wrote back to confirm if the changes worked for him or not. Please let me know what steps we should take to solve this issue. We are very interested in purchasing your product because everything else about the GridView seems to work perfectly for us, but this is a problem which must be solved. Thanks in advance.

Hi all
RadColorPicker does not work fine in the collasped state of RadRibbonGroup.
Thanks

I have an application menu with a RadRibbonDropDownButton(expands to the right). The content of the RadRibbonDropDownButton are a couple of RadRibbonButtons and then another RadRibbonDropDownButton(also expands to the right). In other words I have a RadRibbonDropDownButton within another RadRibbonDropDownButton.

This somehow makes the small arrow on the inner RadRibbonDropDownButton("direction arrow") to point downwards. I have tried to set the DropDownPlacement="Right" and the DropDownButtonPosition="Right" but still the direction arrow is pointing downwards... Shouldn't the the direction arrow be pointing right? Is this somehow a bug caused by the fact that I'm having one RadRibbonDropDownButton within another RadRibbonDropDownButton?
(I have also tried to replace the inner RadRibbonDropDownButton with a RadDropDownButton)

The "direction arrow" on the outer RadRibbonDropDownButton is correctly pointing to the right...
