Tab Key does not work when focused

Murad BASDAG

Hello,

I've coded a new TextBox control like below.

public class DecTextBox : TextBox
{
}

Every thing is working well in my control except for tab key. When the my control focused i cannot go to the next or previous controls by pressing tab and shift-tab keys.

is there anyone who had experienced this issue before.

I could not figure out the reason but the problem is related to change TextAlign property. I was changing it the to RightAlign in Leave event as shown below.

void DecTextBox_Leave( object sender, EventArgs e )
{
this.TextAlign = HorizontalAlignment.Right;
}

When i remove the line my control started to work correspondingly. I can Focus in and out by pressing tab keys.

If you have any idea about why the textalign property does this kind of problem and inform me i'll be appreciated.

Thanks a lot.

Ups.

In first day when i try to give a name to my control's intences, i could not change the name (designed did not accept the new name). But now it's allowed by the designer.

Thank you for your reply but my problem is not related to tab stop or tab index. I have an additional problem with my control. When i create a new instence in designer i can not change the name of it. May this can help to figure out the real problem.

Thank you for your reply. But it's not related to my issue. Because i can get focus into my control by using tab keys. The problem is i can not lost focus from my control by using tab keys.
