I have a Text Box in my form type Decimal

In my code (C#) I want to set value for it

this.thisXDocument.DOM.selectSingleNode("//my:myFields/MyTextBox").text=44.77;

I get an Error. How to do this?

Please keep in mind that in your code you are setting text values regardless of the datatype specified in the schema. The schema identifies how to interperet the text value. But in your code, when setting a value, you must specify a text value when you are using the .text property.

If you want to not convert to a string, you might try using .nodeTypedValue instead. I believe (please verify yourself) that this will allow you to use an actual decimal value.

My Text box is DataType Decimal.
In my code I have this:

this.thisXDocument.DOM.selectSingleNode("//my:myFields/my:MyTextBox").nodeTypedValue= 4.77

I get this Error

"System.Runtime.InteropServices.COMException"
It's work only when the Text Box type is Text!

Do I need do somthing with IXMLDOMNode?
