Cannot set WordWrap option on TextBox inside TabControl

Question

I have a TextBox that is added to each new tab control tab page that gets created at runtime. All properties are set properly (eg Multiline, etc), but when i try to access the textbox from coedbehind there is no option for it. How do I set wordwrap on or off when it's inside a tabcontol's tabpage?

Answer 1

The Controls collection is typed as a collection of Control objects. You will need to cast the returned control to TextBox first:

TextBox textBox = tabControl1.SelectedTab.Controls[0] as TextBox;
if (textBox != null)
{
    textBox.WordWrap = true;
}

Answer 2

try below

var txtBox= tabControl1.SelectedTab.Controls.OfType<TextBox>().FirstOrDefault() as TextBox;
if(txtBox != null)
{
   // do something like txtBox.WordWrap = true;
}
