How to disable a tab index on a control on a form in C#?

In C#, you can disable the tab index on a control on a form by setting its TabIndex property to -1. Here's an example of how to disable the tab index on a TextBox control:

textBox1.TabIndex = -1;

In this example, we set the TabIndex property of textBox1 to -1 to disable its tab index. This means that when the user presses the Tab key to navigate between controls on the form, the focus will skip over textBox1.

You can also use the TabStop property to control whether a control can receive focus using the Tab key. If the TabStop property is set to false, the control cannot receive focus using the Tab key, regardless of its TabIndex value.

textBox1.TabStop = false;

In this example, we set the TabStop property of textBox1 to false, which means that the control cannot receive focus using the Tab key. However, if the user clicks on textBox1, it will still receive focus.

By disabling the tab index or setting the tab stop to false, you can control the order in which controls receive focus when the user navigates through the form using the Tab key.
