I have trouble with moving a canvas in a Window.
<Canvas x:Name="Canvas1" Height="200" Grid.Column="1" Margin="10,15,92,54" Grid.Row="1" Background="#FFECECEC" Grid.RowSpan="2" MouseDown="Canvas_MouseDown" MouseUp="Canvas_MouseUp" MouseMove="Canvas_MouseMove" >
<TextBox Height="100" Width="100" Margin="50,50,327,65" Background="Red"/>
<TextBox Height="100" Width="100" Margin="10,15,327,65" Background="Blue" />
<Canvas.RenderTransform>
<TransformGroup>
<TranslateTransform x:Name="translate" />
</TransformGroup>
</Canvas.RenderTransform>
</Canvas>
This is code behind:
private void Canvas_MouseDown(object sender, MouseButtonEventArgs e)
{
Canvas1.CaptureMouse();
point = Mouse.GetPosition(Grid1);
}
private void Canvas_MouseMove(object sender, MouseEventArgs e)
{
if (Canvas1.IsMouseCaptured)
{
translate.X = e.GetPosition(Grid1).X - point.X;
translate.Y = e.GetPosition(Grid1).Y - point.Y;
}
}
private void Canvas_MouseUp(object sender, MouseButtonEventArgs e)
{
Canvas1.ReleaseMouseCapture();
}
First time, it seem woork fine.
But second time i try to click on my canvas, this move but from initial position.
How can i fix it?
When initializing point on mouse down, subtract the current translation:
private void Canvas1_MouseDown(object sender, MouseButtonEventArgs e)
{
Canvas1.CaptureMouse();
point = Mouse.GetPosition(Grid1);
point.X -= translate.X;
point.Y -= translate.Y;
}
Alternatively, always only add the difference vector:
private void Canvas1_MouseDown(object sender, MouseButtonEventArgs e)
{
Canvas1.CaptureMouse();
point = Mouse.GetPosition(Grid1);
}
private void Canvas1_MouseMove(object sender, MouseEventArgs e)
{
if (Canvas1.IsMouseCaptured)
{
var p = e.GetPosition(Grid1);
var diff = p - point;
point = p;
translate.X += diff.X;
translate.Y += diff.Y;
}
}
Also make sure the Grid doesn't position the Canvas, by setting the Canvas alignment to Top/Left:
<Canvas x:Name="Canvas1" HorizontalAlignment="Left" VerticalAlignment="Top" ...>
And probably don't set a Margin, but instead initialize the TranslateTransform appropriately.
I have 2 columns in my Grid. I will create Button and textbox dynamically in each row. For the dynamic button click, I will show one popup window. The Popup window has some ListviewItems. this is my requirement:
1.If I select any Listview item, it should be displayed on the corresponding textbox.
for example, If it is in the 3rd row, I want to bind the ListviewItem in textbox which is positioned in (Row3, Column1)
this is my xaml:
<Grid>
<DockPanel HorizontalAlignment="Left" Height="165" Margin="40,100,0,0" VerticalAlignment="Top" Width="620">
<ScrollViewer>
<Grid x:Name="grid1" Height="auto" Width="580"/>
</ScrollViewer>
</DockPanel>
<Button x:Name="btn_addnewrow" Content="Add" HorizontalAlignment="Left" Margin="69,43,0,0" VerticalAlignment="Top" Width="89" Height="31" Click="btn_addnewrow_Click"/>
<Popup Name="popup" IsOpen="False" Placement="Mouse" VerticalOffset="15" HorizontalOffset="0" Margin="124,122,107,65">
<Border BorderBrush="Black" BorderThickness="1" Background="Coral">
<StackPanel Orientation="Horizontal" Height="143">
<ListView Margin="10,10,0,0" Name="ListView1" HorizontalAlignment="Left"
VerticalAlignment="Top" Width="194" Height="133" MouseDoubleClick="ListView1_MouseDoubleClick">
<ListViewItem Content="Coffie"></ListViewItem>
<ListViewItem Content="Tea"></ListViewItem>
<ListViewItem Content="Orange Juice"></ListViewItem>
<ListViewItem Content="Milk"></ListViewItem>
<ListViewItem Content="Iced Tea"></ListViewItem>
<ListViewItem Content="Mango Shake"></ListViewItem>
</ListView>
</StackPanel>
</Border>
</Popup>
</Grid>
and this is my code:
public partial class DummyTypeofControl : Window
{
public DummyTypeofControl()
{
InitializeComponent();
}
public int count = 0;
public Button btn1;
public Button btn2;
public TextBox txt1;
private void btn_addnewrow_Click(object sender, RoutedEventArgs e)
{
//Creating Rows..
RowDefinition row0 = new RowDefinition();
row0.Height = new GridLength(40);
grid1.RowDefinitions.Add(row0);
//Creating columns..
ColumnDefinition col0 = new ColumnDefinition();
ColumnDefinition col1 = new ColumnDefinition();
col0.Width = new GridLength(50);
col1.Width = new GridLength(70);
grid1.ColumnDefinitions.Add(col0);
grid1.ColumnDefinitions.Add(col1);
int i = count;
//1st Column button
btn1 = new Button();
btn1.Margin = new Thickness(10, 10, 0, 0);
btn1.BorderThickness = new Thickness(0);
btn1.Name = "btn1_" + i;
Grid.SetRow(btn1, i);
Grid.SetColumn(btn1, 0);
btn1.Click += btnBindList_Click;
grid1.Children.Add(btn1);
//2nd column Textbox
txt1 = new TextBox();
txt1.Margin = new Thickness(10, 10, 0, 0);
txt1.Name = "txt" + i;
Grid.SetRow(txt1, i);
Grid.SetColumn(txt1, 1);
grid1.Children.Add(txt1);
count++;
}
private void btnBindList_Click(object sender, RoutedEventArgs e)
{
popup.IsOpen = true;
}
private void ListView1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
?
?
?
?
popup.IsOpen = false;
}
}
I want to take the rows count and bind listview itms to the corresponding rows textbox dynamically.. i dont know how to continue further.. could any one please help me?
Did not quite understand what you wanted, but give this a try.. a bit unconventional.
private void btn_addnewrow_Click(object sender, RoutedEventArgs e)
{
.....
//let the button know about the textbox
btn1.Tag = txt1;
}
Then, everytime you click on
private void btnBindList_Click(object sender, RoutedEventArgs e)
{
//get the linked textbox and keep it stored int txt1
txt1 = ((Button)sender).Tag as TextBox;
popup.IsOpen = true;
}
Then, when you click on on the listview
private void ListView1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
txt1.Text = (ListView1.SelectedItem as ListViewItem).Content.ToString();
popup.IsOpen = false;
}
There are better and cleaner ways to do this
on click event ,I have return adding of menu items to contextmenu.but on clicking more than once it keeps adding the menu items to the contextmenu. Here the below code am using for it.
<StackPanel Grid.Row="13" Orientation="Horizontal" FlowDirection="LeftToRight">
<Button Name="btnMobile" Content="Home" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0 0 20 0" Width="70"></Button>
<!--<extToolkit:DropDownButton x:Name="ddBtnMobile" VerticalAlignment="Top" Width="30" HorizontalAlignment="Right" Margin="0 0 30 0" Height="20"/>-->
<Button HorizontalAlignment="Left" Name="ddBtnMobile" Width="30" Click="OnddBtnMobileClick" Margin="0,0,0,5" >
<Button.Content>
<Path x:Name="btnArrow3" Margin="4" VerticalAlignment="Center" Width="10" Fill="#FF527DB5" Stretch="Uniform" HorizontalAlignment="Right" Data="F1 M 301.14,-189.041L 311.57,-189.041L 306.355,-182.942L 301.14,-189.041 Z "/>
</Button.Content>
<Button.ContextMenu>
<ContextMenu Name="cMenu">
</ContextMenu>
</Button.ContextMenu>
</Button>
</StackPanel>
code am using is below
private void OnddBtnMobileClick(object sender, RoutedEventArgs e)
{
mnItem = new MenuItem();
mnItem.Header ="B1";
cMenu.Items.Add(mnItem);
mnItem = new MenuItem();
mnItem.Header ="A1";
cMenu.Items.Add(mnItem);
mnItem = new MenuItem();
mnItem.Header="B 2";
cMenu.Items.Add(mnItem);
cMenu.AddHandler(MenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));
}
private void OnMenuItemClick(object sender, RoutedEventArgs e)
{
RoutedEventArgs args = e as RoutedEventArgs;
MenuItem item = args.OriginalSource as MenuItem;
string header = item.Header.ToString();
if (header == "Business")
{
btnMobile.Content = header;
}
else if (header == "Assistant")
{
btnMobile.Content = header;
}
}
how to solve my issue.. Is there any better way of writing the above logic. i.e., adding menu items of context menu at run time.
add a boolean data member which will check if the sub menu's were already added
private void OnddBtnMobileClick(object sender, RoutedEventArgs e)
{
if(alreadyAdded == true)
return;
alreadyAdded = true;
mnItem = new MenuItem();
mnItem.Header ="B1";
cMenu.Items.Add(mnItem);
mnItem = new MenuItem();
mnItem.Header ="A1";
cMenu.Items.Add(mnItem);
mnItem = new MenuItem();
mnItem.Header="B 2";
cMenu.Items.Add(mnItem);
cMenu.AddHandler(MenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));
}
Add the following code in the button click event's starting.
cMenu = new cMenu();
Thats you need to create a new instance.
Thanks,

When Click BrowseButton Its get the file from open Dialog box and it put into the Lable control as FileNameLabel
private void BrowseButtonClick(object sender, RoutedEventArgs e)
{
System.Windows.Forms.OpenFileDialog dlg = new System.Windows.Forms.OpenFileDialog();
dlg.InitialDirectory = "c:\\";
dlg.Filter = "Media files (*.wmv)|*.wmv|All Files (*.*)|*.*";
dlg.RestoreDirectory = true;
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string selectedFileName = dlg.FileName;
FileNameLabel.Content = selectedFileName;
McMediaElement.Source = new Uri(selectedFileName);
McMediaElement.UpdateLayout();
McMediaElement.Play();
}
}
private void Element_MediaOpened(object sender, EventArgs e)
{
timelineSlider.Maximum = McMediaElement.NaturalDuration.TimeSpan.TotalMilliseconds;
}
// When the media playback is finished. Stop() the media to seek to media start.
private void Element_MediaEnded(object sender, EventArgs e)
{
McMediaElement.Stop();
}
its does not play the media file.so Plaese Suggest what the problem in code.
I'm kinda confused with some problem, I'm doing a project where the user should be able to design questions with radio buttons, combo box, etc (kinda like toolbox from VS10 to design your XAML).
So far I can drag and drop an UIElement that I previously created, problem comes when the user creates a new element from my toolbox, I can't find the way to make that new UIElement to get the same events from my previosly created UIElement. Take a look at the code

}
private void combo_Selected(object sender, RoutedEventArgs e)
{
Console.Write("Combo");
textBlock.Text = (String)listBox.SelectedIndex.ToString();
}
}
Thanks!
If all you want to do is handle the mouse down on the new RadioButton, change this line:
newRadio.PreviewMouseDown += generic_PreviewMouseDown(newRadio,?????);
To this:
newRadio.PreviewMouseDown += generic_PreviewMouseDown;
Edit
And then you need to change the generic_PreviewMouseDown to the following:
private void generic_PreviewMouseDown(object sender, MouseEventArgs e)
{
UIElement elem = sender as UIElement;
Point x = e.GetPosition(canvas1);
if (e.LeftButton == MouseButtonState.Pressed)
{
Canvas.SetLeft(elem, Canvas.GetLeft(elem) + (x.X - p.X));
Canvas.SetTop(elem, Canvas.GetTop(elem) + (x.Y - p.Y));
}
p = x;
}
