Hello rajesh,

You could use get_numberFormat()  property of the RadNumericTextBox client object to access the number format object. Here is an example how you could change the negative and positive patterns:

$find("RadNumericTextBox1").get_numberFormat().NegativePattern = "$(-) n";
$find("RadNumericTextBox1").get_numberFormat().PositivePattern = "$(+) n";

I know this is an old post, but I'm trying to change a RadNumericTextbox formatting client side and I followed the code above and it seems to be working but when I type in a number I get the previous format, set from the server side.  I examined the .get_numberFormat() object after setting it and it shows the correct values, but the behavior is from before the format was reset.  Any ideas?

function OnCalcTypeChange(sender, eventArgs
 {
 var entityKeyName = $find("<%=RadGridMultiIncomeSummary.ClientID%>").get_masterTableView().get_dataItems()[0].findControl("txtCurrentAmount");
                var txtBoxId = entityKeyName._clientID;
                var item = eventArgs.get_item();
                if (item.get_text() == 'A')
                {
                    $find(txtBoxId).get_numberFormat().NegativePattern = "$ -n";
                    $find(txtBoxId).get_numberFormat().PositivePattern = "$ n";
                    $find(txtBoxId).get_numberFormat().DecimalDigits = 0;
                }
                else
                {
                    $find(txtBoxId).get_numberFormat().NegativePattern = "-n%";
                    $find(txtBoxId).get_numberFormat().PositivePattern = "n%";
                    $find(txtBoxId).get_numberFormat().DecimalDigits = 2;

                    var nf = $find(txtBoxId).get_numberFormat();
                }
            }

Hello Steven,

I just tested this on our demos, and seems to be working.
Navigate to: http://demos.telerik.com/aspnet-ajax/numerictextbox/overview/defaultcs.aspx
And type in the console:

var format = $find("ctl00_ContentPlaceholder1_RadNumericTextBox1").get_numberFormat();
format.PositivePattern = "$ n";
format.DecimalDigits = 3;

And then change the value of Units to 123.456
Then you will get "$ 123.456" as visible value when you blur.

Could you share with us more details about the problem?

Thank you Vasil for the quick reply. Sorry I left out, this is all happening in a RadGrid.  Turns out the issue is the line below.  It's pulling the first row "[0]"  I need to find out a way to determine which row I need (it varies) and then feed that to the client side.  Anyway that's not your problem, it's mine, thank you very much for your help.  -  Steven

var entityKeyName = $find("<%= RadGridMultiIncomeSummary.ClientID%>").get_masterTableView().get_dataItems()[0].("txtCurrentAmount");
