I prefer to be pre-emptive. When I passed 40, I realised that I enjoyed being a grumpy old sod, so I didn't have to worry about any touchy feely crap.

I find that waiting for some idiot to provide me with a basis for my comments allows me to better organize my thoughts.

I have a WPF project containing a RichTextBox.
I want the text not to wrap. I can force this by setting the PageWidth for the contained FlowDocument to be a large number. However, I really want the PageWidth to adjust itself to the length of the longest line (paragraph), so that the horizontal scroll bar thumb will have an appropriate length.
I tried setting PageWidth to Auto, but this did not prevent wrapping.
Thanks for your suggestions!

the thing here is if i click anyother place in the screen, i have to close that extra widnow????
can any one help me regarding this, thanks now itslef.

To close a window you can use the Close[^] method.
e.g.,
yourWindowObject.Close();

i am using an WPF application..
here the visual children count is comming as 0..
even i am having number of childrens there. how to get the visual childer?
|

If you're getting 0 as a visual children count, this means you're probably looking in the wrong place. Try to get the count AFTER youc call InitializeComponent in your window.

yes mr hanlon..
i m calling this method at the end of my constructor, in which the first step of my constructor is that initialize component
|
|

You are doing it too soon. As a test, add a button to your form, add a click event handler and add the call to TraverseVisualTree to the click handler.

i m using one wpf window.. in that i have some number of canvas,..
i have to do some functions dynamically for all the canvas..
for that i have to take all the canvas together in loop..
for that in windows we will use like
foreach(Canvas cv in this.controls)
cv.visiblity = hidden..
like this we wil do..
but in WPF
i m unable to take the this.controls..
how to take that one???
|
|
|
|

If you have the name of the Canvas elements then you can do a FindName[^] using the the window object
else you would have to use VisualTreeHelper[^] [^]
|
|
|
|
|
The controls are laid out using a Visual Tree, so you walk the tree to find children. To do this, you use the VisualTreeHelper class to get the children. Something like this will do it:
internal static void TraverseVisualTree(object current)
{
DependencyObject ob = current as DependencyObject;
int counter = VisualTreeHelper.GetChildrenCount(ob);
for (int i = 0; i < counter; i++)
{
object depObj = VisualTreeHelper.GetChild(ob, i);
TraverseVisualTree(depObj);
}
}
}All you do then is call:
TraverseVisualTree(this);

yes mr, hanlon..
but u have given the object current as paramater...
that is it expects an object as parameter..
what is that object ?? what i have to send there
|
|
|
|

I already answered that, when I told you how to call it. You can use the this parameter in your Window/UserControl class.

Hi i create my own Grid using ListView Control in WPF
There are couple of think in which i am facing problem.

Note i use the GetFocus event for the ListViewItem but it fire at first time when i click the button. i just want that when button isChecked the the listViewItem Opacity should 1.0 and if not Checked then it should 0.4.
2. When i select any listView item the selection colour is Blue how can i chage that color.

<Setter Property="MaxHeight" Value="75" />
<Setter Property="MinHeight" Value="75" />
<Setter Property="MaxWidth" Value="110" />
<Setter Property="MinWidth" Value="110" />
<Setter Property="Opacity" Value=".5" />
<Style.Triggers>
<EventTrigger RoutedEvent="Mouse.MouseEnter">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation

I will try to clear my idea
I need to make a vertical list of photos that animate from up to down this is my simple idea
in the previous xaml code you will notice that I put one button that animate from up to down repeatedly
I want to put many photos but each photo has its own start and end point
and when the photo reach the down I want to push it in the first (ie return it to the top)
I hope that i cleared my idea
