Changing the text of the button (at runtime) [duplicate]

Question

This question already has an answer here:

showing dynamic text in silverlight (1 answer)

Closed 8 years ago.

I have a button which shows "click me!" on it. I want to see after clicking, it shows "Do not click on me!" permanently.

I get the below error message in buttonname_click() function and I do not know how to resolve it (I have spent so much time on it).

The name 'buttonname' does not exist in the current context

I am attaching Search.xaml and Search.xaml.cs in this question.

Answer 1

You could try this instead:

    private void buttonname_Click(object sender, RoutedEventArgs e)
    {
     ((Button)sender).Content = "Do not click on me!";
    } 

But, to run your code as is, you need to specify the name with x:Name instead of Name:

<Button x:Name="buttonname" Content="click me!" Click="buttonname_Click" Margin= "0,100,0,0"  Height="93" Width="518"></Button>

Answer 2

<Button x:Name="buttonname" Content="click me!" Click="buttonname_Click" Margin= "0,100,0,0"  Height="93" Width="518"></Button>

private void buttonname_Click(object sender, RoutedEventArgs e)
    {
     this.buttonname.Content = "Do not click on me!";
    }
