You can try one more thing - copy your entire code, delete this xaml file, add a new one and paste this code in there. It sounds a little crazy, but once in a way it works. The reason is, the temporary code file created for this xaml may have this ImageListViewItem reference missing.

Thanks.
But I found another way :
Image img = FindName("ImageListViewItem") as Image;
It works.
|

|

I tested your way. It doesn't work 
I receive these errors :
Error 1 The name 'Image_GridViewColumnName' does not exist in the current context
Error 2 Unknown build error, 'Could not find file 'D:\My Works\C#\WPF\passwordManager\obj\Debug\passwordManager.exe'. Line 8 Position 2.'
BTW: I have changed the name to Image_GridViewColumnName

I agree with the previous poster. Clean the solution, delete the bin and obj folders in each project folder, then rebuild the solution. I tried your XAML and, after I added the event handlers, everything compiled fine.

The problem you've hit is that you have the name of this item in a cell template. WPF needs to do some tricks to prevent name collisions - hence you can't directly reference this item. You need to read up on name scopes[^].

It's not WPF that you need to consider, but rather whether or not your application violates any of the rules that have been put in place in Vista as a result of the security elevation.

As Pete said it is a significatly difference security model between these two OSes. Make sure your app doesn't write to it's private installation location and in stead writes to Application Data, that sort of thing.

What's not working?
Make sure your web service is called asynchronously so the UI thread
can show the control. That's just a guess based on the complete lack of
information in your post.

I am attemptimg to programmatically highlight a selection of text in a textbox.
I trying to achieve this by so doing:
tbxItemUrl.SelectionStart = 0;
tbxItemUrl.SelectionLength = pageDetailItemSection.tbxItemUrl.Text.Length;
tbxItemUrl.SelectionBackground = new SolidColorBrush(Colors.Yellow);
tbxItemUrl.SelectionForeground= new SolidColorBrush(Colors.Black);
but to no avail.

Also, your code probably didn't work because the TextBox didn't have focus.
This worked for me:
System.Windows.Browser.HtmlPage.Plugin.Focus();
tbxItemUrl.SelectionStart = 0;
tbxItemUrl.SelectionLength = tbxItemUrl.Text.Length;
tbxItemUrl.SelectionBackground = new SolidColorBrush(Colors.Yellow);
tbxItemUrl.SelectionForeground = new SolidColorBrush(Colors.Black);
tbxItemUrl.Focus();

Thanks for the replies.
Really appreciated.
The focus definitely works, thank you, however i have multiple textboxes that i am looking for matches in and would like to highlight any matches in all the necessary textboxes.
Setting the focus would only then highlight 1 textbox.
Any suggestions would be welcome.
Thanks again.

You'll need to do highlighting something like

Hi,
Is there any way to find out gradient colors and stops from image?
I have mockups of screen from my user experience guy. From those i want to find out gradient stops (points) and colors he used. currently I am using Paint.net and expressing blend and getting the colors creating them in XAML for the same. GradientStops are the biggest challenge.
Thanks

I don't think there is any tool to infer gradient information from an image. This seems like it could get rather complicated. What you might be able to do is create a differential image. You can create an image where each pixel represents the maximum difference in color between that pixel and the pixels neighboring it in the source image. That way, you can have a visualization of the changes in color, rather than just a visual of the colors. That should help you identify exactly where changes to changes (i.e., gradient stops) occur in the image. You could go a step further and make another image that is a differential image of the differential image. This will allow you to see changes in changes in changes (that may be useful for visualizing polynomial gradients that change into different polynomial gradients).
But you'd have to build that tool yourself (unless anybody knows of a tool that can do that). I'd say just eyeball it or have your user experience guy use Expression Blend so you can see the actual XAML that creates the image.

Thanks. Yes, using expression blend by user experience was one of the options we explored, but he is not that familiar with it and he is the only one in team and using EB is time consuming.

What tool is he using to mockup the screens? If he's using something like Photoshop, there is a XAML converter available - take a look here[^] for details.

Thanks for the suggestion and yes he is using Photoshop. I will try using the tool you pointed to.

Well, I would suggest that you might get a better answer on this site[^] which is dedicated to the software.

i have constructed a 3D object using WPF and i want to rotate that object. i also use the following code to rotate the object:
<Transform3DGroup>
<RotateTransform3D x:Name="rotate_center_x" CenterX="1" CenterY="0" CenterZ="0">
<RotateTransform3D.Rotation>
<AxisAngleRotation3D x:Name="rotatex" Axis="1,0,0" Angle="0" />
</RotateTransform3D.Rotation>
</RotateTransform3D>
<RotateTransform3D x:Name="rotate_center_y" CenterX="0" CenterY="1" CenterZ="0">
<RotateTransform3D.Rotation>
<AxisAngleRotation3D x:Name="rotatey" Axis="0,1,0" Angle="0" />
</RotateTransform3D.Rotation>
</RotateTransform3D>
<RotateTransform3D x:Name="rotate_center_z" CenterX="0" CenterY="0" CenterZ="1">
<RotateTransform3D.Rotation>
<AxisAngleRotation3D x:Name="rotatez" Axis="0,0,1" Angle="0" />
</RotateTransform3D.Rotation>
</RotateTransform3D>
but the problem is, when i rotate the object for a certain angle in x, y and z axis, and come to x-axis again, it doesn't rotate the same direction as previous. you can see the similar types of scenario in the following link.

may be here the object rotate along its local coordinate, not its world coordinate. how can i solve this problem?

Alright, here's what I've got. I have an IEnumerable collection of type <Person> containing some random info (name, age, etc). I create a PagedCollectionView using my <Person> collection and bind it to a DataGrid. Then I make a PropertyGroupDescription using the "Name" property of my <Person> object and voila, I've got a datagrid that is grouped by name.
////code for above///////////////
PagedCollectionView pagedCollectionView = new PagedCollectionView(Person.GetPeople(), true, false);
PersonDataGrid.ItemsSource = pagedCollectionView;
PropertyGroupDescription namePropertyGroupDescription = new PropertyGroupDescription("Name");
pagedCollectionView.GroupDescriptions.Add(namePropertyGroupDescription);
/////////////////////////////////
Now instead of just showing the name of the group and the number of items in the RowGroupHeader, I would like to show a DataGrid containing the 1st row of each group. Using this code:
<Grid x:Name="LayoutRoot" Background="White" HorizontalAlignment="Center">
<data:DataGrid x:Name="PersonDataGrid" AutoGenerateColumns="False">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<data:DataGridTextColumn Header="Age" Binding="{Binding Age}" />
<data:DataGridTextColumn Header="Height" Binding="{Binding Height}" />
<data:DataGridTextColumn Header="Weight" Binding="{Binding Weight}" />
<data:DataGridTextColumn Header="Phone Number" Binding="{Binding Phone}" />
</data:DataGrid.Columns>
<data:DataGrid.RowGroupHeaderStyles>
<Style x:Name="DataGridRowGroupHeaderStyle" TargetType="data:DataGridRowGroupHeader">
<Setter Property="SublevelIndent" Value="0" />
<Setter Property="Height" Value="80" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<data:DataGrid AutoGenerateColumns="False" HeadersVisibility="None" ItemsSource="{Binding Items}">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<data:DataGridTextColumn Header="Age" Binding="{Binding Age}" />
<data:DataGridTextColumn Header="Height" Binding="{Binding Height}" />
<data:DataGridTextColumn Header="Weight" Binding="{Binding Weight}" />
<data:DataGridTextColumn Header="Phone Number" Binding="{Binding Phone}" />
</data:DataGrid.Columns>
</data:DataGrid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</data:DataGrid.RowGroupHeaderStyles>
</data:DataGrid>
</Grid>
I've got all of the items in the group showing up in the grid contained in the RowGroupHeader. Is there any way to just show the first row of each group in my RowGroupHeader? I've tried using a converter:
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
List<Person> personList = (value as IEnumerable<Person>).ToList();
return new List<Person> { personList[0] };
}
but I can't get it to work properly. Any ideas?
