Hi Please have a look at the code.By implementing the below control teplate for a combobox.the cursor is coming out of combobox.Please aadvise. <ControlTemplate x:Key="ComboBoxToggleButton" TargetType="{x:Type ToggleButton}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition Width="20"/> </Grid.ColumnDefinitions> <Rectangle Grid.ColumnSpan="2" HorizontalAlignment="Stretch" x:Name="Rectangle" VerticalAlignment="Stretch" Width="Auto" Height="Auto" RadiusX="5" RadiusY="5" Fill="{DynamicResource NormalBrush}" Stroke="{DynamicResource NormalBorderBrush}"/> <Rectangle Grid.Column="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" RadiusX="5" RadiusY="5" Fill="{DynamicResource WindowBackgroundBrush}" Stroke="{DynamicResource NormalBorderBrush}"/> <Path Grid.Column="1" HorizontalAlignment="Center" x:Name="Arrow" VerticalAlignment="Center" Fill="{DynamicResource GlyphBrush}" Data="M 0 0 L 4 4 L 8 0 Z"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter Property="Fill" Value="{DynamicResource MouseOverBrush}" TargetName="Rectangle"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter Property="Fill" Value="{DynamicResource PressedBrush}" TargetName="Rectangle"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Fill" Value="{DynamicResource DisabledBackgroundBrush}" TargetName="Rectangle"/> <Setter Property="Stroke" Value="{DynamicResource DisabledBorderBrush}" TargetName="Rectangle"/> <Setter Property="Foreground" Value="{DynamicResource DisabledForegroundBrush}"/> <Setter Property="Fill" Value="{DynamicResource DisabledForegroundBrush}" TargetName="Arrow"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> <!-- This is the area which contains the selected item in the ComboBox --> <ControlTemplate x:Key="ComboBoxTextBox" TargetType="{x:Type TextBox}"> <!-- This must be named as PART_ContentHost --> <Border x:Name="PART_ContentHost" Focusable="False" Background="{TemplateBinding Background}"/> </ControlTemplate> <!-- Simple ComboBox This uses the ComboBoxToggleButton to expand and collapse a Popup control SimpleScrollViewer to allow items to be scrolled and SimpleComboBoxItem to def

This sounds like the expander contol.

First, where is the above code running? Which event handler? Second, why not just loop through the Items collection in the ComboBox and check each CheckBox? Then you won't need all that code. Get Mole or Snoop and have a look at your application's Visual Tree so that you can understand what your looping through. It is very easy once you understand this.

Can you please provide a more detail of what you are trying to accomplish? This article I wrote covers using a CheckBox inside a ListBox so the binding will be similar in that you'll use a Data Template to accomplish what you need. http://www.codeproject.com/KB/WPF/WPFProblemSolving.aspx[^] Cheers, Karl » CodeProject 2008 MVP » Microsoft MVP - Client App Dev My Blog | Mole's Home Page | MVP Profile Just a grain of sand on the worlds beaches.

I don't know what you are binding to so I can't help you there I'm afraid. You'll need to provide more information there. However, saying that - if I were you I'd look to implement a PropertyChangedCallback in your data class. Have a look at this[^] thread. Deja View - the feeling that you've seen this post before.

Hi karl Thanks a lot for your advise.I will try it out :)

Is this in a browser scenario, or is this in a desktop scenario? With ASP.NET, the best way to upload a file is with the FileUpload control. In a desktop situation, use WebRequest.Create() to create a web request. Set the ContentType property on the request, and then get a response for it: WebRequest request= WebRequest.Create(url); request.ContentType="multipart/form-data"; request.Method="POST"; Stream stream=request.GetRequestStream(); //write to the stream... WebResponse response= request.GetResponse(); //check the response to see if the file was uploaded successfully --Justin Microsoft MVP, C# C# / Web / VG.net / MyXaml expert currently looking for (telecommute) contract work![^]

Use a System.Net.WebClient object, set the Headers property values and use the UploadDataAsync() method to send file, this class also has a Proxy Property may be usable to you. :):rose: Sojaner!

Thanks for your detailed reply.Its working fine. But I have one more doubt regarding memory usage.When I run the application the memory is 170 000K, when I minimise the app, it drops drastically. Is it ok?I heard the task manager does not show accurate memory usage. Do I need to take any action? Or in the start of the program, do I programmatically minimise the form and maximise again? Please clarify my doubts. Thanks

Hi perlmunger Thanks a lot for your advises,they are very useful for us , I will avoid using Kill method and try to trace out the wrong thing in my App. I will get back to you if any doubts. Thanks Aruna
