The only way I can think of doing this would be to extend the RTB and insert a custom run, which you would use. You would basically handle the keypresses in your RTB and see if you were inside the run - if you were, you'd suppress the keypresses - if not, you'd let them bubble up.

Thanks Pete! I'd actually come to the same conclusion and was hoping there was an easier way 
Cheers,

Just incase anyone hits the same issues as I did, the solution to this problem is quite simple and was solved using an InlineUIContainer and TextBlock (although it took me ages to figure it out) and I've pasted the code snipped below for your reference:
void rtb2_SelectionChanged(object sender, RoutedEventArgs e)
{
Match m = Regex.Match(rtb2.Selection.Text.ToString(), "<.*>");
if(m.Success)
{
string tag = m.ToString();
TextRange tr = new TextRange(rtb2.Selection.Start,rtb2.Selection.End);
System.IO.MemoryStream ms = new System.IO.MemoryStream();
tr.Save(ms, DataFormats.Rtf);
string rtbString = ASCIIEncoding.Default.GetString(ms.ToArray());
System.Text.RegularExpressions.Regex findTags =
new System.Text.RegularExpressions.Regex("<.*>");
rtbString = findTags.Replace(rtbString, "");
System.IO.MemoryStream msOut = new System.IO.MemoryStream();
System.IO.StreamWriter sw = new System.IO.StreamWriter(msOut);
sw.Write(rtbString);
sw.Flush();
msOut.Seek(0, System.IO.SeekOrigin.Begin);
tr.Load(msOut, DataFormats.Rtf);
TextBlock myTextBlock = new TextBlock(new Run(tag));
myTextBlock.Background = Brushes.WhiteSmoke;
TextPointer tp = rtb2.CaretPosition.GetInsertionPosition(LogicalDirection.Forward);
InlineUIContainer myInlineUIContainer = new InlineUIContainer(myTextBlock, tp);
}
And there you have it, my first codeproject solution  Hope it proves useful to someone!
Happy coding,
Drew

Nice one Drew. Well done.

Super, thanks! This will definitely help me figure out some stuff I've been planning to look at (but putting off).
Always great when someone else can do the figuring out for you. 
Cheers.

Can any one Help
I have created one Panel Control(System.Windows.Forms) using wpf window application and create one user control using Windows Control Library.
I want to add the usercontrol in Panel
I have tried the following code
<window x:class="Sivam.Window1" xmlns:x="#unknown"><br />
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"<br />
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"<br />
xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"<br />
xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"<br />
Title="Sivam" Height="300" Width="300" Loaded="Form_Load"><br />
<br />
grid><br />
windowsformshost margin="7.37,6.72333333333333,48,22"><br />
wf:panel height="50" x:name="panel1" text="Prompt" xmlns:wf="#unknown" /><br />
/windowsformshost><br />
/grid><br />
<br />
/window>;<br />
</window>
private void Form_Load(object Sender, EventArgs e)<br />
{<br />
UserControl1 uc1 = new UserControl1();<br />
panel1.Controls.Add(uc1);<br />
<br />
<br />

But I got the Error
Convert System.Windows.Controls to System.Windows.Forms.Controls
Thanks,

It looks to me like you either have a namespace issue, or you're trying to add the wrong type somewhere. For example, if UserControl1 is a WPF control (which it appears to be), you can't add that to a windows forms panel. Use the Canvas class instead.
The windows forms host is for hosting windows forms controls inside a WPF window.

Hi,
Can we have a custom control which works like our asp.net datalist control.
Actually I want its repeatcolumn functionality.
I had tried few things as below
<window.resources>
<serviceimages x:key="serviceImages" xmlns="clr-namespace:OptiQ_TokenGen.Controller" xmlns:x="#unknown" />
</window.resources>
<canvas>
<wrappanel canvas.left="70" canvas.top="250" width="600" height="600" orientation="Horizontal">
<itemscontrol itemssource="{Binding Source={StaticResource serviceImages}}">
<itemscontrol.itemtemplate>
<datatemplate>
<image source="{Binding Path=NormalImage}" />
</datatemplate>
</itemscontrol.itemtemplate>
</itemscontrol>
</wrappanel>
</canvas>
Here ItemsControl which actually shows my bounded things in images and its parent control is WrapPanel which should wrap its inner control but i dont know what is wrong with this its not doing so.
Help me out.
thanks

I'm looking for a simple way for a part of a window to become transparent, like a hole, that "cuts through" what it is directly on top of and shows what is underneath.
Or, more concretely, I want to design a little close button that is a circle with an X, but I want the X to actually be a hole in the circle that you can "see through" to whatever the button is sitting on.
Before you answer, here's my guess:
Create a circle, then create a region marking the "X", and subtract that region from the circle, treating the final shape as the button.
The question is how easy is this (can it be done in XAML?), and are there any pitfalls to watch out for?
Cheers
Logan

...yeah... that's the general idea. Lol thanks. Alas I don't have Fireworks, and I don't think I know enough to tweak those seemingly random values by hand.
It looks good tho, so I might just use that for now, if you don't have any objections.

No objections here.

You mean you can't read them? And I thought they were soooooo obvious.

Nice. Very nice. Cheers mate.

No bother ... the timing is impeccable as I was looking to use the Infragistics DockManager control ...
Mmmm ... WPF goodness!

I have a custom control that expands upon mouse click, if i put my control in a groupbox, the border of the group box gets drawn on top of the part that expands outside the groupbox size. Any idea how to make this appear on TOP of it? I want to make it like the ComboBox dropdown works by default (always on top of anything).

|

Then would you also have to manage the location of the popup when the window is moved, as it does not move with the window once displayed. Is there not a better way to implement this?
|
|
|
|

Not if you want it to extend past the bounds of its containing layout panel, at least not any that I know of (but then again I'm new to this too).

If you are simply talking about ordering the layers inside a canvas or grid cell, however, take a look at Panel.ZIndex.

Hi,
How can I change Image's source on MouseDown event?
Thanks
|
|
|
|
|
I would use an EventTrigger to do this.
|
|
|
|
|
I have the same problem, and EventTriger is not allowing me to use a Setter 
Can you be more specific?
Thanks
