Set focus on textbox in WPF

Set focus on a TextBox in WPF like a boss 💥💻

So you want to be the master of setting the focus on a TextBox in WPF, huh? 🤔 No worries, I've got your back! Let's dive right in and solve this common issue. 🔍

The Problem 😕

So you've set your mind on focusing that TextBox element, and you've attempted the old trusty method:

txtCompanyID.Focusable = true;
txtCompanyID.Focus();

But, oh no! 😱 It's just not working as expected. Don't fret, my friend. We'll sort this out together! 💪

The Explanation 📚

The thing is, the Focus() method is a bit picky when it comes to TextBox elements in WPF. Why, you ask? Well, it's because TextBox is a content control, and it needs to have its Focusable property set to true before you can call the Focus() method. 😮

However, there's more to it! 🤓 In order to successfully focus on a TextBox, not only do we need to set the Focusable property to true, but we also need to make sure that the TextBox has been loaded into the visual tree.

This means that you may need to wait for the TextBox to be fully loaded before you can set the focus. So, be a little patient and get ready for the solution coming up next. 💡

The Solution 💡

To set the focus on a TextBox in WPF, you can follow these steps:

1. Make sure the TextBox is loaded:

   txtCompanyID.Loaded += (sender, e) => txtCompanyID.Focus();

2. Set the Focusable property to true:

   txtCompanyID.Focusable = true;

That's it! Simple, right? Your TextBox will now dazzle with focus like a star! ✨
