How do I get the GridView Cell Value when I direct click on the Save Button after typing something in a GridView Cell, without tab-out/Lost Focus?

I am using Telerik RadGridView for WPF. I have a scenario where a user types some value in the RadGridView cell and then clicks on the save button. I want to get the updated value that the user just typed in the cell. When I tab-out from the cell then I can get the updated value in CellEditEnded event. But in my scenario I don't want to tab-out from the RadGridView cell.

DataMemberBinding AND CellTemplate on custom object

Hi,

I'm disappointed to not successfully bind a column on a custom object: is it possible to display a custom object in a cell of a grid ?

If i use DataMemberBinding jointly with CellTemplate, the dataContext of the gridviewcell is not my property but still the 'row object':

Is GridViewDataColumn's purpose to bind on 'simple properties' ?

Thanks a lot,

Example: The 2nd column doesn't display the button content neither bind the command because the datacontext of the cell is still a 'Row' object and not and 'Item' object.

Code:

public class MyViewModel : Telerik.Windows.Controls.ViewModelBase

{

public MyViewModel()

{

this.ItemsSource = new ObservableCollection<Row>()

{

new Row() { RowName = "Row 1" },

new Row() { RowName = "Row 2" },

new Row() { RowName = "Row 3" },

};

}

public ObservableCollection<Row> ItemsSource { get; set; }

}

public class Row

{

public Row()

{

this.Item = new Item();

}

public Item Item { get; private set; }

public string RowName { get; set; }

}

public class Item

{

private static Random rnd = new Random();

public Item()

{

this.Display = string.Format("Item {0}", rnd.Next(1, 999));

this.FireItem = new Telerik.Windows.Controls.DelegateCommand((object o) =>

{

System.Diagnostics.Debug.WriteLine("Double click on " + this.Display);

});

}

public string Display { get; set; }

public ICommand FireItem { get; set; }

}

Xaml :

<Window.Resources>

<local:MyViewModel x:Key="MyViewModel" />

<DataTemplate x:Key="ItemTemplate">

<Button Width="75"

Height="75"

Command="{Binding FireItem}"

Content="{Binding Display}" />

</DataTemplate>

</Window.Resources>

<Grid>

<telerik:RadGridView AutoGenerateColumns="False"

DataContext="{Binding Source={StaticResource MyViewModel}}"

IsReadOnly="True"

ItemsSource="{Binding ItemsSource}">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding RowName}"

Header="Stage" />

<telerik:GridViewDataColumn CellTemplate="{StaticResource ItemTemplate}"

DataMemberBinding="{Binding Item}"

Header="Item" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

AutomationMode

Hello
What are the possible drawbacks of disabling the AutomationManager?

AutomationManager.AutomationMode = AutomationMode.Disabled;

It drastically improved shape manipulation. It was extremelly slow when resizing and creating shapes before changing the AutomationMode.

My question is, what is this for? What am I losing by disabling it? I've read the documentation but didn't understand it well.

Thank you!!

ResourceDictionary Source File VS local Style

Hi,

why is this working:

<telerik:RadRibbonWindow

d:DesignHeight="450" d:DesignWidth="800">

<telerik:RadRibbonWindow.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<!--<ResourceDictionary>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</telerik:RadRibbonWindow.Resources>

<Grid>

<TextBlock Text="Hallo" />

</Grid>

</telerik:RadRibbonWindow>

where the content of RibbonWindowStyle.xaml is:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

>

<Style TargetType="local:ProceedTest" BasedOn="{StaticResource RadRibbonWindowStyle}" />

</ResourceDictionary>

and this is not working:

<telerik:RadRibbonWindow

</telerik:RadRibbonWindow.Resources>

<Grid>

<TextBlock Text="Hallo" />

</Grid>

</telerik:RadRibbonWindow>

For me both versions should end up in the same result, or what is the difference?!

When loading an XLSX file, the active worksheet's tab is not selected!

I am using the latest release. I have this code -- I even tried manually forcing the selection, but it didn't help any:

Workbook spreadsheetWorkbook = new XlsxFormatProvider( ).Import( result );

//I tried to force the active worksheet, but this doesn't help either!

spreadsheetWorkbook.ActiveWorksheet = spreadsheetWorkbook.Worksheets.FirstOrDefault( );

foreach ( var sheet in spreadsheetWorkbook.Worksheets )

{

sheet.ViewState.IsSelected = false;

}

if ( spreadsheetWorkbook.ActiveWorksheet != null )

{

spreadsheetWorkbook.ActiveWorksheet.ViewState.IsSelected = true;

}

spreadsheet.Workbook = spreadsheetWorkbook;

And the result is attached.

Please advise...

Regards,

Spreadsheet

How to change the full text search behavior?

Hi,

is it possible to change the full text search behavior from contains to start with?

The users whant e.g. to search vor zip codes and they do not want to see a lot of other results... pls see attached pic.

If it is possible is it also possible to switch the behavior at run time? Than I could provide a checkbox where the user can switch back to "contains-mode".

Thanks for help!!!

TypeConverter is not working

Hello,

I have followed your WPF example:

public class PlayerTypeConverter : TypeConverter

{

public override bool GetStandardValuesSupported(ITypeDescriptorContext context)

{

return true;

}

public override bool GetStandardValuesExclusive(ITypeDescriptorContext context)

{

return true;

}

public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)

{

return new StandardValuesCollection(new string[] { "Mark Wright", "Ian Rush", "John Barnes",

"Paul Ince", "Jamie Redknapp", "Sami Hyypia", "Steven Gerrard ", "Jordan Henderson" });

}

and attached the converter to my property:

/// <summary>

/// Sets the algorithm that is available for the mode.

/// </summary>

[Category("Reconstruction")]

// [Editor(typeof(AlgorithmEditor), typeof(UITypeEditor))]

[Telerik.Windows.Controls.Data.PropertyGrid.Editor(typeof(ComboBox))]

[TypeConverter(typeof(AlgorithmConverter))]

[Description("Sets the algorithm that is available for the mode.")]

public string Algorithm

{

get => GetProperty<string>();

set => SetProperty(value);

}

Unfortunately when setting the property to the PropertyGrid the combobox does not show up.

The type converter is not even used. Originally I had the PropertyInspector which is still active until I have transitioned to the RadPropertyGrid, here the TypeConverter is used without any problems.

What could be the problem?

Thanks

Martin
