[Solved] NumericTextBoxSetting - Real numbers?

[Brad]

How do I set a textbox that has been assigned to a NumericTextBoxSetting control to accept real numbers. ie: a number with any number of decimal places.

The DecimalDigits property allows the setting to be 0 up to 99. This is not what I need.  What if my user enters a number with 600 decimal places?

Here is my code.

TextBox tbFloat = new TextBox();

string fID = ID + "Value" + i2;

tbFloat.ID = fID;

tbFloat.Attributes.Add("name", fID);

tbFloat.Text = Value;

c2.Controls.Add(tbFloat);

  

Telerik.Web.UI.NumericTextBoxSetting radF = new Telerik.Web.UI.NumericTextBoxSetting();

radF.EmptyMessage = "";

//radF.DecimalDigits = ? ;




radF.Type = Telerik.Web.UI.NumericType.Number;

radF.Validation.IsRequired = false;

  

TargetInput fi = new TargetInput();

fi.ControlID = fID;

radF.TargetControls.Add(fi);

  

RadInputManager1.InputSettings.Add(radF);

In the code above I have commented out the DecimalDigits line. Running this I get a textbox that accepts real numbers just fine, but always round them down to 2 decimal places! Huh?

I need one that accepts numbers of any number of decimal places.

I even tried this...

radF.DecimalDigits = -1 ;

But that of course does not work (would have been nice if it did) :)

Any clues on this one please?

Thanks

Hello Brad,

Try setting AllowRounding to False and then set DecimalDigits to a large number thus you can handle rounding manually.
C#:

Telerik.Web.UI.NumericTextBoxSetting radF = new Telerik.Web.UI.NumericTextBoxSetting();
radF.EmptyMessage = "";
radF.DecimalDigits = 600 ;
radF.NumberFormat.AllowRounding = false;

Thanks,
Shinu.

That is not possible

According to this page

http://www.telerik.com/help/aspnet-ajax/p_telerik_web_ui_numerictextboxsetting_decimaldigits.html

.DecimalDigits cannot be set to a number greater than 99.

I used 600 as an example. The fact of the matter is I don't want any limit on how many decimal places they enter. This text box is part of a system were an admin of the site can created their own questions and specify the 'type' of answer they are expecting. If they specify the question requires a real floating point number, I don't want it rounded to 2 places OR be limited to some 99 point precision limit.

For example

Question 1:- Enter pi to 150 places.

Can't do that with the NumericTextBoxSettings

Hi Brad,

NumericTextBoxSettingis not designed to work with more than 99 decimal digits. You will have to use a regular TextBox and restrict only numbers to be entered. You could search the web for some solutions like this one.
Keep in mind that in the code-behind you will need to parse the string manually since it can't be casted to double or decimal because they don't provide such a precision.
