I have a custom GridView inherited from ‘RadGridView’ which is binded to generic list.
Some of the rows in the gridview is becoming readonly(Edited values are getting restored to older value when curser moved to next position) while editing(not all rows).
Please help

Hello,
Is there a way to remove the title bar on the RadRibbonView, or hide it? Or at least some way to not have '- My Application' in the title bar text?
Thank you

I have a Usercontrol that I use as my cell's DataTemplate (actually I stick it directly into my controltemplate, but shouldn't make a difference)
I have a DependencyProperty that is bound to the Value of the cell, and the changed-listener looks like this
however, this animation fires when I am scrolling, because of UI virtualization.
I use this animation to flash the cell when the value changes. Is there a better way to do this to avoid getting the animation fired when UI virtualization is in effect? When I turn the virtualization off the problem goes away.

Hello,
I started a new project and using your OpenAccess library just as you did in "WPF MVVM with OpenAccess" sample solution form OpenAccess SDK. AddCommand works fine when I add a single record. But when I try to add multiple records, ViewModel saves only recent inserted item. How do I savе multiple new records?
Thank you.

Hello,
I have a Category class which contains Categories property which is a List<Category>. I use MVVM with your OpenAccess ORM. Here is a XAML markup I use to bind tree to data:
In CategoryViewModel I have the following method:
How do get SelectedItem?
Thank you.
I have a Category class which contains Categories property which is a List<Category>. I use MVVM with your OpenAccess ORM. Here is a XAML markup I use to bind tree to data:
<telerik:RadTreeView HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Name="CategoryTree" ItemsSource="{Binding Path=Categories}" SelectedItem="{Binding Path=CurrentCategory, Mode=TwoWay}" SelectionChanged="CategoryTree_SelectionChanged">
<telerik:RadTreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Categories}">
<TextBlock Text="{Binding Name}" />
</HierarchicalDataTemplate>
</telerik:RadTreeView.ItemTemplate>
</telerik:RadTreeView>
In CategoryViewModel I have the following method:
protected override void Load()As you can see, I iterate through root level categories and they all have a Categories property filled with data. But when I try to select child categories from tree, they select visually on the tree but SelectedItem is always null. This happens because in Load() method I have CollectionViewSource.GetDefaultView(Categories) which returns a list which contains only root categories.
{
_categories = new ObservableCollection<CategoryBO>();
foreach (Category category in _repositoryCategory.Entities.Where(p => p.ParentCategory == null))
{
CategoryBO tempCategory = category;
if (tempCategory != null)
{
Categories.Add(tempCategory);
}
}
_categoryView = CollectionViewSource.GetDefaultView(Categories);
OnPropertyChanged("CategoriesList");
OnPropertyChanged("CurrentCategory");
} and this is how I initialize a CategoryBO object:public static implicit operator CategoryBO(Category category)
{
return new CategoryBO(category);
}public CategoryBO(Category category)
{
ID = category.CategoryID;
ParentID = category.ParentID;
Name = category.Name;
foreach (ProductBO product in category.Products)
{
_products.Add(product);
}
foreach (Category cat in category.Categories)
{
_categories.Add(cat);
}
}
How do get SelectedItem?
Thank you.

Hi --
I'm trying to add some SpellChecker capabilities to a RadGridView. I'm currently auto-generating the columns in the GridView because it's not a fixed object type that will be displayed in the list.
I am looking for a way to either:
Let me know your thoughts -- it would be really cool to get this to work.
Thanks in advance.
I'm trying to add some SpellChecker capabilities to a RadGridView. I'm currently auto-generating the columns in the GridView because it's not a fixed object type that will be displayed in the list.
I am looking for a way to either:
- Have the spell checker work when columns are auto-generated (just apply it to all columns)
- Programmatically add columns to the gridview (MVVM pattern) by using reflection on an object. With any luck, I would be able to use a custom DataAnnotation to indicate whether to use spell check on the generated column. Also could maybe use a different annotation for the column heading??
Let me know your thoughts -- it would be really cool to get this to work.
Thanks in advance.

Hi,
in my application I have a RadGridView for who I create his columns dynamically on a specific event in my application. For each row in this grid, I need a sub grid. To achieve this, I create a GridViewToggleRowDetailsColumn dynamically.
In my XAML, I defined a <telerik:RadGridView.RowDetailsTemplate><DataTemplate><telerik:RadGridView x:Name="subSetGrid".
If I want to create dynamically the columns of my "subSetGrid" and assign it's "DataSource" to simething, how I can do to achieve this???
Thank's

We have used Radgrid view and have fixed width of columns.ON double click of the row content we open a tab.
When we stretch or increase the column width at runtime, it does show the complete bind text and after we double click the extended portion of the row, it does not get the event.
Following is the code example used

using version 2011 Q1
I have a window with a tree view and a grid
when I change the selected item in the tree i run query, build an ObservableCollection and bind it to the ItemSource of the grid.
all grid columns are Width="Auto"
the problem is that when i rebind the ItemSource, the width of columns don't update correctly, actually they don't update at all.
sometimes a column in the the resulting collection has 200 characters at most, other times 25 characters at most.
the columns width does not re size to correctly to 25 characters, it is left at 200 characters, the columns have too much white-space.
is the grid not supposed to do update the columns when the ItemSource gets a new collection?
if not how can I force the columns to adjust to current data collection.
as in one of your examples i have tried to iterate the grid.Columns setting the width to Auto, nothing happened.
your help would be much appreciated.
thanks
