Hi,

I am developing a video editor in WPF, as my final year project. Can you please help me with the timeline process. Like in Adobe Premiere, or any other editing softwares. How can i add my videos, images, etc to the timeline and how to play the timeline?

Thanks

The concept of editing a video, overlaying images, merging sound and text is a huge undertaking.

WPF does not ship a TimeLine control that you can add things to and have them produce a video.

I don't mean to rain on your project, in fact I wish you the best on this.

If I can think about a starting point, I'll post back to you.

Here are some links I found. Check them out.

There program looks nice. I'm not sure where to start. I hope some of the links I provided can get you going. Maybe there are other links on the Internet.

Probably your first task should be, understanding "how" to edit a video file. Write a program that allows adding text or images to a video file.

Once you know "how" editing process works, putting it in a TimeLine should be the easy part.

Help with a WPF Combobox

Aaron Hickman2-Oct-08 14:11

Hi all,

I am really new to WPF and I am trying to create a combo box that has the ability to display an ellipses character if the text is too long (for the selected item). Can anyone help?

<ComboBox Grid.Column="1" Grid.Row="1" IsEditable="False" Width="200">
<ComboBoxItem>Electronics, Game Systems, Cameras & Photo</ComboBoxItem>
<ComboBoxItem>Computers and Networking</ComboBoxItem>
<ComboBoxItem>Clothing, Shoes, and Accessories</ComboBoxItem>
<ComboBoxItem>Books, Music, Movies, DVDs, and Video Games</ComboBoxItem>
<ComboBoxItem IsSelected="True">All Other Categories</ComboBoxItem>
</ComboBox>

Hi Karl,

Thank you for the reply. I actually did see this article before posting. I could not get it to work. How do I set the DataTemplate for the combobox?

User 2710092-Oct-08 17:11

2-Oct-08 17:11

Here is a code snippet from one of my programs.

<ComboBox x:Name="cboBindingPath" SelectedValuePath="Name" VerticalAlignment="Top">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Name}" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>

hmm. I must have something wrong. My code is below. When I select the item that is longer than the width of the combobox it does not show the ellipsis characters. Any thing that you can see that I am doing wrong?

<ComboBox Grid.Column="1" Grid.Row="1" IsEditable="False" Width="200" x:Name="Category">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ElementName=Category, Path=SelectedItem}" TextTrimming="CharacterEllipsis"/>
</DataTemplate>
</ComboBox.ItemTemplate>
<ComboBoxItem>Electronics, Game Systems, Cameras & Photo</ComboBoxItem>
<ComboBoxItem>Computers and Networking</ComboBoxItem>
<ComboBoxItem>Clothing, Shoes, and Accessories</ComboBoxItem>
<ComboBoxItem>Books, Music, Movies, DVDs, and Video Games</ComboBoxItem>
<ComboBoxItem IsSelected="True">All Other Categories</ComboBoxItem>
</ComboBox>

I see what you mean. I have a hack, but want to give you a better solution. I'm in the middle to posting a new version of XAML Power Toys, so I'll get back to this tomorrow night after work.

For now, move ahead, we'll get this.

Aaron,

I've spent the entire weekend updating XAML Power Toys for Silverlight and just published it.

I'll hop on this Monday after work.

I'm just plain beat and brain is out of gas.

I need my creative gas tank full to give you a solution that is not hacky.

Cheers, Karl

Perhaps you can use a valueconverter (erm.. somewhere)

Aaron,

I've spent and hour got it to work but it had an unexpected behavior.

So I'm retemplating the ComboBox to support this. I had to download Blend to do this. Should be another hour or so.

Below are two solutions. One when the ComboBox ItemSource is data bound. The second when the ComboBox items are added in-line.

You can thank Code Project MVP Josh Smith for this solution. He is the real, "Man" and Mr. WPF.

Josh's blog: http://joshsmithonwpf.wordpress.com/


<ComboBox ItemsSource="{Binding}" Width="100" VerticalAlignment="Center">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{TemplateBinding Content}"
TextTrimming="CharacterEllipsis"
TextWrapping="NoWrap" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>


<ComboBox Width="100" VerticalAlignment="Center" SelectedIndex="0">
<ComboBox.Resources>
<Style TargetType="ComboBoxItem">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="{TemplateBinding Content}"
TextTrimming="CharacterEllipsis"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</ComboBox.Resources>
<ComboBoxItem>Greetings from the planet known as Earth</ComboBoxItem>
<ComboBoxItem>Thanks to Josh Smith for this tip!</ComboBoxItem>
</ComboBox>

Cheers, Karl

I was just checking up on your blog. Good stuff. I really appreciate your help with this. I had a little bit of both in my attempts, I just could never get the right "combo". Thanks again.
