Radnumerictextbox

[woutercop]

I need to make a input numeric textbox where only thousands are allow, and minimum value 5000

for example 5000, 7000, 10.000, ....

if some gives in 7300 if has to be rounded to 7000, if 259200 to 259000 >> so rounded to the nearest 1000

i have tried to do the first step (check if it is a thousand) with a 

 <telerik:radnumerictextbox MinValue="5000" ClientEvents-OnKeyPress="" Culture="nl-BE" id="txtBedrag" runat="server">  

 

<NumberFormat DecimalDigits="0" />

 

<ClientEvents OnValueChanged="OnValueChanged" />

 

 

 

</telerik:radnumerictextbox> 

 

 

 

 

 

 

 

<

 

script type="text/javascript">

 

 

 

 

 

function

 

OnValueChanged(sender, eventArgs)

 {

 

var number = aspnetForm.ctl00_ContentPlaceHolder1_txtBedrag_text.value;  

 

 

 

if (number % 1000 > 0)  

 

return false;

 }

 

</script>

Hello Wouter,

You should use the ValueChanging client event.

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

You can check what is the value of the get_newValue() property in the event arguments and if necessary, set the modified value to the set_newValue() property (again in the event arguments).

Generally, the value of the RadInput textboxes should not be manipulated with DOM opeartions (e.g. some_id.value = something), but only by using client API methods, as demonstrated in the documentation.

Let me know if there is anything unclear.
