I wrote this very quick and it seems to work just fine. The only thing is that you need to click the button twice!! That I dont know why?

Good answer

I gave up on this and found another (albeit clunky) solution to the problem I was trying to solve (and the solution has nothing to do with drawing bitmaps, so there's no solution to this particular problem posted).

So Silverlight 4 gives us a RichTextBox, and the RichTextBox gives us an attribute to get the content in Xaml, but there is no way of getting the standard RTF text (compatible with the RTF 1.5 / 1.6 specification)... Or is there?

There is another[^] text box available for silverlight - not sure if this meet RTF specifications.

Thanks, but the replies further down mentions that it is not aligned with the standard RTF format

The silverlight toolkit has a date control and an experimental global calendar control.
The toolkit is open source so you can play around with the source code for these controls.
|

|

I know it buddy.
But I want something that is ready made. I have no time to play
on built in controls.
So if anybody has any idea on it then post reply.

I've a dataGrid in my XAML file. I need to display two separate context-menus on right-click on Rows and Header. Having same context-menu on both is easy, but how to have different ones? Will someone please provide a bit of code?
|
|
|
|

I think, I've got the answer.
<!--ContextMenu Definition-->
<ContextMenu x:Key="cm_rowMenu">
<!--ContextMenu For Row-->
</ContextMenu>
<ContextMenu x:Key="cm_columnHeaderMenu">
<!--ContextMenu For Header-->
</ContextMenu>
<!--ContextMenu Definition Ends-->
<!--Default Header Style-->
<Style x:Key="DefaultColumnHeaderStyle" TargetType="{x:Type Custom:DataGridColumnHeader}">
<Setter Property="ContextMenu" Value="{StaticResource cm_columnHeaderMenu}" />
</Style>
<!--Default Row Style-->
<Style x:Key="DefaultRowStyle" TargetType="{x:Type Custom:DataGridRow}">
<Setter Property="ContextMenu" Value="{StaticResource cm_rowMenu}" />
</Style>
<!--Setting styles for DataGrid-->
<Custom:DataGrid
RowStyle="{StaticResource DefaultRowStyle}"
ColumnHeaderStyle="{StaticResource DefaultColumnHeaderStyle}"/>

Yup - that looks like it should do it.

Hello, i am very new to WPF and so far i like it more than WinForms.
Currently i have a template for ListViewItems. And i want to change the selected style. When i select an item, i see blue background.
Can anyone tell me where shoud i look into?

In WPF, the selected item background colour is determined by System.HighlightBrush. This means that you can define a brush for the style and use SystemColors.HighlightBrushKey to set this. Here's a sample:
<Style TargetType='ListViewItem'>
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red" />
</Style.Resources>
</Style>

I am asking mysely: Why didn't i tried this before
Now i have a diffrent problem. I do not think it is alrigt to contiune new post, but here it is:
This is a stripped down event Template for a ListViewItem template
<DataTemplate x:Key="ListBoxItemPodjetjeTemplate">
<Grid Margin="2">
<Border Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" BorderThickness="0" Background="#8098D8D8" CornerRadius="4,4,4,4"/>
</Grid>
<DataTemplate.Triggers>
<Trigger Property="Control.IsMouseOver">
<Setter Property="Control.Background" Value="LightGreen"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
I put Highlight color to transparent, now i want to change background of an item based on mouse over. Now the trigger is throwing me an exception with an inner text: {"'{DependencyProperty.UnsetValue}' is not a valid value for property 'IsMouseOver'."}.
Thank you in advance

What value are you applying? You haven't actually set one in the Trigger. Try changing it to
<Trigger Property="Control.IsMouseOver" Value="True" />

Aw stupid me. Thank you for your reply

No problems - it's easy to miss something like this. As a hint, if you ever see a message about DependencyProperty.UnsetValue then it means the value the DP expects hasn't been set. This isn't the same as a null value because null might be a legitimate value for the DP.

I'm trying to learn WPF doing some simple stuff before tackling a real project. The first thing I've tried to do is to mock up an Excel sheet used to review case files. It uses 40 some columns to collect reviewers' input. At least 5 columns use the same Excel data validation to limit the responses to:
Yes,
No, or
Unknown
So..in porting this to SQL Server I've put check constraints in that require one of those 3 entries.
In mocking up the data entry form in WPF I would like to use a combobox that IS BOUND to one of those SQL columns and offers the 3 permissible choices. It seems to me that the ideal approach would be to create a template combobox with the 3 choices, and then use and re-use the template for each of the constrained columns.
Maybe my searching skills are poor, but I can't seem to find any explanations or examples of doing something like this, even though it seems as though this sort of thing would be used often.
Where do I start?

Normally, I'd approach this by using MVVM to bind to the items using a user control which contains the combo box, and the VM would contain the values (along with the validation). It's fairly straightforward, so I'd suggest that you have a read up on MVVM (that's Model View ViewModel).

Pete -
Thanks for the response. I have been reading up on MVVM, but my 'programming' background has mostly been Excel VBA and some basic/rudimentary WinForm apps. It's a big step to grasp the concepts behind MVVM.

It is - but once you get it, it makes tasks like this so much simpler.
