Documentation:Text formatting

As you bind data to your model, you may want to influence how that data is presented.

Regretfully, we have not found a straightforward way to do this across all our supported platforms. Instead, we have implemented parallel strategies in order to get the job done.

On a ViewModel column, set Tagged Values in order to convey your wish via the model.

WPF

For WPF, use the tagged value StringFormat. This value is sent into the binding and adheres to the common text transform pattern defined here for numbers, for DateTimes, and for TimeSpan.

WPF is very good at this and allows for the original value to be presented by the format even when the value is two-way bound and editable.

Angular

For Angular, use the tagged value StringFormatAngular. This value is appended behind the binding as an Angular Filter. Angular has basic capabilities and is not able to handle this kind of formatting - for two-way-databind - so it works best for read-only values.

For Angular, you can transform dates according to this guide and numbers according to this guide and currency like this - try this for number format with 2 decimals : number:2

NEW 20250403: numberhash:2 - this will work as the csharp ToString('0.00######') , the given number of minimum decimals but if there are values in lower decimals up to 2 places these are shown

MVC

In MVC, use StringFormatRazor. We can transform in Razor code and thus have many of the same possibilities as in WPF for read-values. Write values are harder so this works best for the one-way bind.

Example for Angular:

Above, I have the same attribute1:double shown 3 times. One of the instances instructs Angular to render as a number with 2 decimals only:

Notice both the trimming of decimals and the addition of the thousand separator.
