how To Type Uppercase String in windows phone TextBox Wpf c#.
I tried it on KeyDown Event.
void TxtPanno_KeyDown(object sender, KeyEventArgs e)
{
TxtPanno.Text = TxtPanno.Text.ToUpper(); //1 code.
TxtPanno.Text= CultureInfo.CurrentCulture.TextInfo.ToUpper(TxtPanno.Text); //2 code
TxtPanno.Text=Regex.Replace(TxtPanno.Text, "^[A-Z]", m => m.Value.ToUpper()); //3 code.
}
But Problems is that.
Cursor always go to leftside.
Try doing:
TxtPanno.Text = TxtPanno.Text.ToUpper();
TxtPanno.SelectionStart = TxtPanno.Text.Length;
TxtPanno.SelectionLength = 0;
It makes the text uppercase, moves the cursor to the end and selects nothing.
You should not try to replace text,instead you should apply styles like this
<Style TargetType="{x:Type TextBox}">
<Setter Property="CharacterCasing" Value="Upper"/>
</Style>
The above style will make all textboxes uppercase, you can change it to only apply to a specific textbook like this
<TextBox CharacterCasing="Upper" />
then when using the text entered, make it upper case.
Finally I tried this code and it worked.
void TxtPanno_TextChanged(object sender, TextChangedEventArgs e)
{
TxtPanno.Text = TxtPanno.Text.ToUpper();
TxtPanno.SelectionStart = TxtPanno.Text.Length;
}
