Hello,

How to bind a parameter to Button?

There are not enough information about your scenario so I could just talk from a simple scenario. Based on your code, you are trying to pass the ID as parameter which should be an int value or a string value.

Then you could try a simple way to do this. You could set the Tag property of the button, bind it to the ID property that you wan to use.

When the click event is fired, you could get the button object and get the Tag value which should be the same value as ID.

Xaml:

<ScrollViewer Width="800" HorizontalAlignment="Center" VerticalAlignment="Center">
<ItemsRepeater Width="300" x:Name="itemsRepeater1" HorizontalAlignment="Center" VerticalAlignment="Center" >
<DataTemplate x:DataType="local:TestModel">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="47"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Button Content="{x:Bind Name}" Click="myButton_Click" Tag="{x:Bind Id}" />

                </Grid>  
            </DataTemplate>  
        </ItemsRepeater>  
    </ScrollViewer>  

Code-behind:

    private void myButton_Click(object sender, RoutedEventArgs e)  
    {  
        Button button = (Button)sender;  

        var tag = button.Tag;  

    }  

Thank you.
