Adding a counter to a DataTemplate












0















I have a DataTemplate for an ItemsControl that outputs a Grid with some binded controls, and this works as expected.



However, I want the first column of the Grid to output a counter of each Grid made.



For example...



<DataTemplate x:Key="myDataTemplate">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="75" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>

<TextBlock Text="X" /> <!-- I want a counter to go here -->
<TextBox Grid.Column="1" Text="{Binding Path=Name}" />
</Grid>
</DataTemplate>


I want that first TextBlock to display 1, 2, 3, 4, etc... as the DataTemplate outputs new Grids.



Any ideas on the best way to do that?



Thanks!

          You can achieve this using AlternationCount and AlternationIndex of ItemsControl. Like,



          <ItemsControl ItemsSource="{Binding Items}" AlternationCount="{Binding Items.Count}">
          <ItemsControl.ItemTemplate>
          <DataTemplate x:Key="myDataTemplate">
          <Grid>
          <Grid.ColumnDefinitions>
          <ColumnDefinition Width="75" />
          <ColumnDefinition Width="150" />
          </Grid.ColumnDefinitions>

          <TextBlock Text="{Binding Path=(ItemsControl.AlternationIndex), RelativeSource={RelativeSource TemplatedParent}}" />
          <TextBox Grid.Column="1" Text="{Binding Path=Name}" />
          </Grid>
          </DataTemplate>
          </ItemsControl.ItemTemplate>
          </ItemsControl>


          This will give you 0 based index; you can use IValueConverter if any changes needed.
