Hi,

I am working with a project there I am making a list with colours and some text.
To add text and colour codes it's working fine.

Here is the XAML code:

XML

<ListView Grid.Row="0" Margin="5" Name="lvCustomStream" Width="Auto">
  <ListView.View>
    <GridView >
      <GridViewColumn Header="Length" Width="90" DisplayMemberBinding="{Binding Length}" />
      <GridViewColumn Header="Speed" Width="90" DisplayMemberBinding="{Binding Speed}" />
      <GridViewColumn Header="Colour1" Width="90" DisplayMemberBinding="{Binding Colour1}" />
      <GridViewColumn Header="Colour2" Width="90" DisplayMemberBinding="{Binding Colour2}" />
    </GridView>
  </ListView.View>
</ListView>
<Grid Grid.Row="2">
<Grid.RowDefinitions>
  <RowDefinition Height="Auto"/>
  <RowDefinition Height="Auto"/>
  <RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
  <StackPanel Orientation="Horizontal" Grid.Row="2">
  <Button x:Name="btCsSave" Width="40" Margin=" 5" Content="Save" Click="btCsSave_Click"/>
  <Button x:Name="btnCsCancel" Width="40" Margin="5" Content="Cancel"     Click="btnCsCancel_Click"/>
  </StackPanel>
<StackPanel Orientation="Horizontal" Grid.Row="1">
  <Label Margin="5,5,0,5" Width="Auto" Content="Length"/>
  <TextBox x:Name="txtCsLength" Margin="0,5,5,5" Width="40"/>
  <Label Margin="5,5,0,5" Width="Auto" Content="Speed"/>
  <TextBox x:Name="txtCsSpeed" Margin="0,5,5,5" Grid.Row="1" Width="40"/>
  <Label Margin="5,5,0,5" Width="Auto" Content="Colour1"/>
  <Rectangle x:Name="rectCsColour1" Margin="0,5,5,5" Grid.Row="1" Width="25" MouseDown="txtCsColour1_MouseDown" Fill="#FFFBD904"/>
  <Label  Margin="5,5,0,5" Width="Auto" Content="Colour2"/>
  <Rectangle x:Name="rectCsColour2" Margin="0,5,5,5" Grid.Row="1" Width="25" Fill="#FFF9F904" MouseDown="rectCsColour2_MouseDown"/>
</StackPanel>
</Grid>

The code behind:

C#

private void btCsSave_Click(object sender, RoutedEventArgs e)
  {
    if (txtCsThreadLength.Text == "") return;
    lvCustomStream.Items.Add(new CsItem(txtCsLength.Text.ToString(),  txtCsSpeed.Text.ToString(), rectCsColour1.Fill.ToString(), rectCsColour1, rectCsColour2.Fill.ToString()));
  }

What is missing is: when I click on the save button, I want to get the two rectangles too into the ListView after the two colour values, not just the two Colour-values, Speed and Length.

Thanks in advance

Not clear. Where do you try to add a rectangle object after the window is already shown? All you show is doing something with string, which looks irrelevant to the question.

Yes the window shows the rectangle and I can change the colour in it, and when I click the save button I want that rectangle to be copied with the value of colour in the List View.

DisplayMemberBinding on GridViewColumn will display thetext representation of the binding property.

You need to set CellTemplate of GridViewColumn to a template that you want to display the data, along the lines

XML

<gridviewcolumn header="Colour1" width="90">
    <gridviewcolumn.celltemplate>
        <datatemplate>
            <rectangle fill="{Binding}"></rectangle>
        </datatemplate>
    </gridviewcolumn.celltemplate>
</gridviewcolumn>
