Text Box Methid

Question

Hi  I have a screen with a text box . I want to be able to edit a number to show as currency before the screen is loaded and when someone enters a number I want it to show as currency. I cannot figure out which method I would use to put my code in. The text box is txt_Final_Sale. I tried txt_Final_Sale_Enter((object sender EventArgs e) { } But it did not activate. Can anyone tell me which property or method I need to use to execute code for the text box? Thanks

you can use the following javascript function; use this java script function in your aspx page and call it in onblur from your page behind. function validate() { if(document.getElementById(txt_Final_Sale_Enter).value==) { alert(Please Enter The Amount); document.getElementById(txt_Final_Sale_Enter).focus(); return false; } else { document.getElementById(txt_Final_Sale_Enter).value = '$' + document.getElementById(txt_Final_Sale_Enter).value; } } Now call this function in onblur from pagebehind. protected void Page_Load(object sender EventArgs e) { if (!IsPostBack) { txt_Final_Sale_Enter.Attributes.Add(OnBlur return validate()); } }

I am using a data reader to read the value from databasewhich is a numeric and I am converting it to currency in following way. txtCashAmount.Text = Convert.ToDouble(sdrData[cus_cur_MaximumCashAmount]).ToString(C);
