RadGridView crashes when sorting edited column

Hi,

I use RadGridView in my project...

when i change the value at some row (only happen at textbox, when i change value at checkbox/combobox it doesn't happen) and then try to sort the column ascending or descending it crashes.

It only happens when i set AutoGenerateColumns to false (which is always the case in our application..)

To enable sorting, I set DataMemberBinding of each column.

The error I get is:

"The runtime has encountered a fatal error. The address of the error was at 0x5b7d157d, on thread 0x430. The error code is 0x80131623. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code."

The code I use:

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding MyArray}">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<AdornerDecorator>
<TextBox Text="{Binding Name}" />
</AdornerDecorator>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>

Display count of shown rows insteads of count of groups

Hello,

i am trying to use DataPager to display the count of rows in GridView, which are filtered or grouped in the GridView.

Then i have the Binding of Items with GridView.

<telerik:RadDataPager

            Grid.Row="1"

            PageSize="25"

            Source="{Binding Items, FallbackValue={x:Null}, ElementName=GridView}"/>

My problem is that, if i use Groupe function of GridView, i will see the number of groups insteads of the number of shown rows of GridView in DataPager.

Has somebody solved this problem? Thanks a lot!

Disable DataPager from code behind

We need to be able to enable or disable a DataPager associated with a GridView when the window loads (some users want it and other don't). I have tried setting the visibility to collapsed, setting IsEnabled to false and setting Source to null in the window constructor. None of these work. The pager isn't visible but the grid only shows the first page of data. The grid's ItemsSource is bound to an ObservableCollection and is populated in the Window_Loaded event. Here is the relevant xaml:

</telerik:RadGridView>

<telerik:RadDataPager x:Name="DpEvents" Grid.Row="2" Source="{Binding Items, ElementName=grdEvent}" PageSize="18"

DisplayMode="All" AutoEllipsisMode="Both" NumericButtonCount="10" IsTotalItemCountFixed="True" />

Set MaskedDateTimeInput Text property doesn't affect the value

Hi,

I'm migrating from RadMaskedTextBox to the new mask controls and encountered the following problem with MaskedDateTimeInput.

Up until now I used to set the "Text" property of the control, because my data structure holds the value as string with the correct format.

When I try setting the "Text" property of MaskedDateTimeInput via code to a certain date string, it doesn't affect the "Value" property.

When I click on the control it changes the text back to the current date.

I know I can use the value property but that requires me to convert my text value into DateTime and I don't want to do that if it can be done automatically via the control.

Please advice

How to use IconSources

Hello,

in the new features of the Q3 2015 version, it is that we can use IconSources to change the icons used for a RadRichTextBox UI.

Unfortunately, the documentation is very poor: http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/how-to/switching-icons-at-runtime
1. Where do I need to put this XAML code?
2. Where do I specify the set of icons to use?

And most important:
3. How can I define my own icons for RadRichTextBox?

Thanks in advance

[Solved] SetBinding in AutoGeneratingField

Hi,

I have a DataForm with AutoGenerateFields="True". In the AutoGeneratingField event handler I want to set a binding on the IsReadOnly property for some of the fields, so that when the FromProfile property is checked, those fields will be set as ReadOnly. The strange thing is that the binding only works if FromProfile is True when the AutoGeneratingField is fired. The DataField's ("Port", "Protocol" and "Interface") is set ReadOnly whenever the "FromProfile" DataField is checked. If FromProfile is False at the time the binding is set up, it doesn't work.

The AutoGeneratingField event handler looks like this:

01.if (e.DataField.Label.Equals("Port") || e.DataField.Label.Equals("Protocol") || e.DataField.Label.Equals("Interface"))

02.{

03. var binding = new Binding("FromProfile")

04. {

05. Mode = BindingMode.OneWay,

06. UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged,

07. };

08. e.DataField.SetBinding(DataFormDataField.IsReadOnlyProperty, binding);

09.}

Any idea why it doesn't work?

Regards,

DataForm
