I have a textbox, the maxlength is 10. What I want is to add leading 0's to the text.
For example:
input 1, then 0000000001
input 12, then 0000000012
input 123, then 0000000123
I tried Padding a numeric display in WPF
It is not working and I don't want to use code behind text changed event. I'd prefer pure xaml.
UPDATED:
The code is simple. Something like
<TextBox Text="{Binding Info,StringFormat={}{0:0000000000}}" MaxLength="10" />
It shows 0000000000 in the first place, then you can't input the 11th letter to let the byte shift to the left afterwards.
Assume you binding a int type property to TextBox.Text, all you need to do is setting Binding.StringFormat correctly.
<TextBox Text={Binding path to you int property, StringFormat=d10}/>

I bind single properties to a TextBox without a specific StringFormat with the intension to show the value exactly like the user entered it.
<TextBox x:Name="TBSingleValue" Text="{Binding Path=SingleValue, ValidatesOnDataErrors=True}" />
The current automatic StringFormat creates the following result:
123456789 => 1.234568E+08
0.123456789 => 0.1234568
I need to display the values within -10e-9 and 10e9 without the scientific formating or automatic round.
With a StringFormat:
<TextBox x:Name="TBSingleValue" Text="{Binding Path=SingleValue, ValidatesOnDataErrors=True, StringFormat={}{0:F9}}" />
it parsed as expected but now I get every Decimal place, even when the value doesn't need one.
4 => 4.000000000
So here my Question:
Do you know what kind of StringFormat I should use to display every enteres Decimal place without showing unnessessary ones?
Best case would also a support of , and . as Decimal delimiter.
Edit:
I came up with a quite simple solution:
<TextBox x:Name="TBSingleValue" Text="{Binding Path=SingleValue, ValidatesOnDataErrors=True, StringFormat={}{0:0.###########}}" />
The custom StringFormat character # shows a digit only if one is present. The 0 at the beginning ensures that there is a 0 at the beginning even for numbers of 0.001.
This structure disables the scientific notation and gives the number with the required precision, without unnecessary 0 at the end.
Even -0.00000001 is displayed correct.
I have an WPF Textblock to which I bind a view model property, let's say, 'Lines'.
Lines view model property contains three lines separated by the newline character \r\n as below:
IDXXXAZZ000000000099898T<<<<<<\r\n9999999M8888778XXX<<<<<<<<<<<3\r\nXXXX<XXXXX<<XXXXXXX<XXXX<<<<<<
So I am trying to put them in the TextBlock as below:
IDXXXAZZ000000000099898T<<<<<<
9999999M8888778XXX<<<<<<<<<<<3
XXXX<XXXXX<<XXXXXXX<XXXX<<<<<<
As you can see above all three lines always have the same number of characters, 30 characters each one, but for some reason lines does not appear to end at the same point, that is, instead of displaying them like above, they are displayed like below:
I have tried below TextBlock:
<TextBlock Grid.Row="11"
Grid.Column="1" Grid.ColumnSpan="2"
Margin="0 10 0 0"
Text="{Binding Path=Lines}"
FontFamily="Verdana"
FontSize="9" />
So what's the problem? type of font family? font size? I do not understand it.
I'm still new to wpf so this might be a pretty simple question but I wasn't able to find a solution anywhere
I have a Combobox that I've bound to an ObservableCollection of bytes. Once I populate the list I want the values to be displayed in hex format with '0x' in the beginning
so for e.g if the list contains
0
120
255
then the combobox should display
0x00
0x78
0xFF
How do I do this without any code behind and in the simplest way possible?
Note - I tried using the ItemStringFormat property but I wasn't able to get it to display in the way I wanted
This should do what you want:
<ComboBox ItemsSource="{Binding Path=testArray}">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ., StringFormat=0x{0:X2}}"/>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Basically, you are replacing the default "String" item with the above item template that allows you to use a more usable custom formatting string.
The "." Binding binds to the whole item object (in this case, the byte), and the format string is the same kind of string you could pass to String.Format in code-behind.

I want to to show the duration in minutes on my control but I don't want it to show up as with decimal numbers (eg, 65 instead of 65.94503).
<TextBlock Text="{Binding Duration.TotalMinutes, StringFormat=\{0\} minutes}" />
How can I do it?
If you want an integer to display, I think that all you need to do is set the StringFormat property as follows:
<TextBlock Text="{Binding Duration.TotalMinutes, StringFormat=N0}"/>
Do that in code instead of the markup. You can unit test that easily. Make TotalMinutes a string or int instead and format it in the ViewModel.
I am binding an object to a TextBox with the following XAML:
<TextBox Name="MyTextBox" Text="{Binding Path=MyValue, Mode=TwoWay, StringFormat={}{0:F2}}" />
Naturally when I bind a new object (which values are all still zero) the Text property is set to 0.00. I have several of these TextBoxes, which makes it tedious to delete every value before entering a new one.
At the moment I'm clearing these boxes in the Window_Loaded method using the FindVisualChildren method.
It just feels clunky though. Is there a neat way of doing this?
Try the following:
StringFormat={}{0:#.##}
It will format to two decimal places and won't show zeroes.
