EhteshamSiddiqui — 8/23/2011 1:06:59 PM

Hi,

My application is in Silverlight,coded in C#.Net in VS2010.

I have a form with a Imagebox and a Browse button below it.

My requirement is when the user clicks on Browse button OpenDialog should be opened and the User should be able to click and select an Image file and when the User selects an Image file than that selected Image should be loaded to the Imagebox.

I have written some code but just facing the problem of Providing the Source to Imagebox.

Below is my Code

01.OpenFileDialog imageDialog = new OpenFileDialog();

02.

03. //Filter default filetype to be allowed for selection

04. .Filter = "Pictures (*.jpg)|*.jpg";

05. imageDialog.FilterIndex = 1;

06.

07. //Allows multiple files to be selected

08. imageDialog.Multiselect = true;

09.

10. //Call the ShowDialog method to show the dialog box

11. bool? userClickedOK = imageDialog.ShowDialog();

12.

13. //Process input if the user clicked OK

14.

15. if (userClickedOK == true)

modify/Update the UI in silverligt

Mallikarjun06 — 12/5/2011 9:35:22 AM

Hi,

I am new to the Silverlight concept & still learning it. I have a question.

In ASP.NET, we had practice to have the UI in the ASPX page & the code behind moved to dll. I mean the business logic for the UI was from a class library & only the UI to be in ASPX pages. When the application is shipped to customers, they had the ASPX pages & the dependent assemblies & the CSS. Customers had options to modify content of the ASPX page like any button alignment/increasing the width/height of any controls in that ASPX pages if required. Also change the CSS. So how can we achieve the same in Silverlight?

Thanks,

Mallikarjun

Hi,

I am a beginner in silverlight. I have just installed silverlight 5. I wanted to utilise the bookshelf silverlight control but when i open it with my visual studio, it says that two of the files are not downloaded properly. So, i downloaded several times but still the same outcome. I would like to know why and help me solve this problem. This silverlight bookshelf control is downloaded from http://classifiedcabinet.codeplex.com/ . I went to the "sample" section of the particular page that you are navigated to when click on the above link and download the source.

Hi,

I am a beginner in silverlight.There are some problems with the file when i open it with visual studio but i am confuse about it.

It is as follows:

Error 10 Undefined CLR namespace. The 'clr-namespace' URI refers to a namespace 'Samples.Bookshelf.Admin' that is not included in the assembly.

Error 11 The type 'local:ViewModelLocator' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

Warning 2 The referenced component 'Microsoft.Expression.Interactions' could not be found.

Warning 3 The referenced component 'System.Windows.Controls.Data.DataForm.Toolkit' could not be found.

Warning 4 The referenced component 'System.Windows.Controls.Data.Toolkit' could not be found.

Warning 5 The referenced component 'System.Windows.Controls.DataVisualization.Toolkit' could not be found.

Warning 6 The referenced component 'System.Windows.Controls.Input.Toolkit' could not be found.

Warning 7 The referenced component 'System.Windows.Controls.Layout.Toolkit' could not be found.

Warning 1 The referenced component 'System.Windows.Controls.Toolkit' could not be found.

Warning 8 The referenced component 'System.Windows.Controls.Toolkit' could not be found.

Warning 9 The referenced component 'System.Windows.Interactivity' could not be found.

Does it mean that i have to download something that is not downloaded previously?

Silverlight 5: Changing a ControlTemplate Property dynamically

mk222 — 2/10/2012 12:53:42 AM

Hello everybody,

I have a little problem, which keeps me going nuts now for two days. I am a XAML Rookie, but I have 5 years experience with WinForms & Co. Maybe I don't need a very deep explanation, maybe just a good example or hint would help me, but I am now at a point where I know, I need some help.

Ok. Here is the deal:

I have a ControlTemplate that I use for buttons. This Template has two images. The super simple thing I want to do is, to change the source of the images for every button instance in the XAML Code. The goal is simple: The whole bevavior for every button is the same, the images are different.

This is how I use the template in XAML:

<Button Template="{StaticResource PictureButtonTemplate}" Grid.Row="1" Height="48" HorizontalAlignment="Left" Margin="108,21,0,0" Name="button2" VerticalAlignment="Top" Width="48" Background="Black">Button>


And this is the ControlTemplate itself:

<ControlTemplate x:Key="PictureButtonTemplate" TargetType="Button">
        <Grid>
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="Disabled"/>
                    <VisualState x:Name="Normal"/>
                    <VisualState x:Name="Pressed"/>
                    <VisualState x:Name="MouseOver">
                        <Storyboard>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="mouseOverImage">
                                <DiscreteObjectKeyFrame KeyTime="0">
                                    <DiscreteObjectKeyFrame.Value>
                                        <Visibility>VisibleVisibility>

                                    DiscreteObjectKeyFrame.Value>

                                DiscreteObjectKeyFrame>

                            ObjectAnimationUsingKeyFrames>

                            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="normalImage">
                                <DiscreteObjectKeyFrame KeyTime="0">
                                    <DiscreteObjectKeyFrame.Value>
                                        <Visibility>CollapsedVisibility>

                                    DiscreteObjectKeyFrame.Value>

                                DiscreteObjectKeyFrame>

                            ObjectAnimationUsingKeyFrames>

                        Storyboard>

                    VisualState>

                VisualStateGroup>

            VisualStateManager.VisualStateGroups>

            <Image x:Name="normalImage" Source="Grafiken/Icons/48x48/Man.png"           Margin="0" Stretch="Fill" HorizontalAlignment="Center" VerticalAlignment="Center" Width="Auto"/>
            <Image x:Name="mouseOverImage" Source="Grafiken/Icons/48x48/eraser_fav_48.png" Margin="0" Stretch="Fill" Visibility="Collapsed"       HorizontalAlignment="Center" VerticalAlignment="Center" Width="Auto"/> Grid>

 ControlTemplate>


In the control template, you can see two images. I just want to change these images dynamically in XAML. 
How can I do this?
 BTW: I also have implemented a code behind file for this ControlTemplate. So everything is possible, I just need a hint.....
Thank you.
Michael, Hamburg.
