How to get the Text of TextBlock (TextBlock is Content of Button)

Question

a TextBlock is inside a Button as content.

I want the Text property of the TextBlock. Please kindly advice how I can solve this.

Below code only return ct as System.Windows.Controls.TextBlock

string ct = (sender as Button).Content.ToString();

Of course, the Content of Button is really a TextBlock System.Windows.Controls.TextBlock
I found very similar case in stackoverflow but people only provided wrong answer.

have you tried `string ct = ((sender as Button).Content as TextBlock).Content;` ? — ericosg, Feb 12 '16 at 07:53

Since the Content of the Button is TextBlock you should consider (sender as Button).Content as a TextBlock then use the Text property like this:

string ct = ((sender as Button).Content as TextBlock).Text;

There are few ways to solve your problem. First one is just cast Button content and get the text:

var button = (sender as Button);
if(button == null)
{
    // handle this scenario
}

var textBlockContent = button.Content as TextBlock;
if(textBlockContent == null)
{
    // handle this scenario
}

var ct = textBlockContent.Text;

The second one you can find your TextBlock by name or just reference it if you have event handler in the same control:

var textblock = (TextBlock)this.FindName("YourTextBlockName");
if(textblock == null)
{
    // handle this scenario
}

var ct = textblock.Text;

Also you can try to change your XAML code to store just a text in your button:

<Button Content="YourText" Backround="..." Foreground="..." Style="..." />

So many thanks for your excellent, kindness. All 3 persons brought right answer to me..Have comfortable day ! — Kay Lee, Feb 12 '16 at 08:19
