how to create keypress event for textbox control(wpf application)
please help.
thank you.
|

In your textbox declaration, add the following handler:
PreviewKeyDown="KeyDownHandler" In the codebehind, you will add the code:
private void KeyDownHandler(object sender, KeyEventArgs e)
{
}WPF allows you to preview commands, so there is no need to use a keypress to validate the item because you can cancel it here by setting e.Handled = true; in response to your test.

how to create reports(same crystal reports) using access or sql server compact 3.5 data base for wpf application. please help.
Thank You.

That's a fairly broad scope you've got there. Are you asking how you recreate all of Crystal in WPF, or do you just want to display a tabular report? I would suggest that you might want to look at one of the commercial grid controls such as the Xceed WPF grid control then you can display reports quite easily.

Hi
I am just trying to convert my web app developed in .net to Silverlight.
So I am worried about repeating all the lengthy code(for design in xaml page)every time.So if anybody knows or can guide to come out of this.In simple words I need a replacement of MasterPages or Include files in silverlight 2 Beta 2.

You can add a DLL reference to use any previously build classes and methods.
Nirav_Vyas wrote: MasterPages
There is no native support for master pages in silverlight. However to implement a similar functionaly, you can do something like this:
- Create your main page (acting as a master page) such that you leave some space for your content (similar to the content place holder)
- Create separate user controls for each of the pages and build some logic to dynamically load the appropriate user control into that content space
Hope that gives an abstract idea.

Hey guys...
still busy writing the calender control in WPF, now I've got a silly little issue.
[Background Info]
This control will be used as a roster, so a shift needs to be allocated do a specific day.
When the day is not used(its a blank block OR there is no shift allocated on that day) its background is Grey. If a shift is allocated to a day that days background goes blue, if the day is an off day the background goes RED.
All the day numbers of the cells are black text, accept Sundays which have red text.
[/Background Info]
my problem is having an off day on a Sunday, you cant see the day number(red text on a red background), id like to try and have a black outline for the red text...
Any thoughts, ideas or links?
Thanx alot

Create a FormattedText object to represent your text, and then use BuildGeometry to create a Geometry object on this. See here[^] for ideas how to accomplish this.

The below code is XAML, no code is required.
<RichTextBox>
<FlowDocument>
<Hyperlink>
<Image Source=" PUT THE IMAGE PATH & NAME HERE " />
</Hyperlink>
</FlowDocument>
</RichTextBox>

oh i got it working now.  But now i need it in C# code cause i need this stuff to be dinamicaly created

Cool.
Well, XAML is just another method of creating objects.
So just create the objects in code and nest them just like the XAML is.
RichTextBox and FlowDocument creation in code is an advanced WPF topic. But I'm the same way, if its hard, just go for it.
There is a SUPER book on writing WPF code: http://www.charlespetzold.com/wpf/index.html[^]
I strongly suggest you have a look at this. You can probably get a used one on www.Amazon.com.

Hey guys...
ive got a WPF control(calender), im using a grid to split it up into cells. Each cell contains a Border, Canvas, WrapPanel, and two textBlocks.
The 1st Textblock will be used for the number that represents the day of the month and the 2nd will have a string value. I cant seem to get the 2nd textBlock to behave like i need it to.
I need its text to wrap around if the sting is vertically too long for the grid cell to show it all, and i need to "Dock" the stack panel to the canvas so that its the same size(and ontop of) as the canvas.
Heres my XAML for a single cell
<Border Name="Border00" Grid.Column="0" Grid.Row="2">
<Canvas Name="Canvas00" Grid.Column="0" Grid.Row="2" >
<StackPanel>
<TextBlock Name="dayTxt00" Text="1" />
<TextBlock Text="WPF Shift Harvey Blah" HorizontalAlignment="Center" FontSize="8" Foreground="#AAFF0000"/>
</StackPanel>
</Canvas>
</Border>
any ideas?
Thanx

To solve your second question, you can bind the width and height of the StackPanel to it's parent.
<Canvas>
<StackPanel Height="{Binding ActualHeight,
RelativeSource={RelativeSource AncestorType=Canvas}}"
Width="{Binding ActualWidth,
RelativeSource={RelativeSource AncestorType=Canvas}}">
</StackPanel>
</Canvas>
After that, just make sure to set the text wrapping property on the TextBlock and you should be all set

Hey guys,
For some strange reason i cant seem to get events working in on of my WPF controles, its basically a calender(in progress so there isnt much happening yet) and each cell that represents a day in the month must be able to handle left and right click events.
The control uses a Grid, there are also border objects so that the grid lines are visible, and the cells representing the days have canvas objects in them.
Im sure that im overlooking something stupid, but i cant seem to figure out why the events arent firing. the control is being used in a winForms solution if thats of any help.
<Edit>
After i nested the controls properly, and then registered the event on the lowest control(in my case the border) the events worked
