RadInput - automatic postback after reaching maxlength

[Roel]

Hi,

Is there a way to have a client-side postback when the input in a textbox reaches the maximum length?

The input is generated by a bar-code scan, but unfortunately the scanner can't be configured to trigger a carriage return after input.

Thanks,
Roel

Hi Roel,

You can try the following code snippet to achieve the desired scenario.

ASPX:

<telerik:RadTextBox ID="RadTextBox1"  runat="server" Width="640px"   ClientEvents-OnKeyPress ="test" >
        </telerik:RadTextBox>

JS:

<script type="text/javascript">
function test()
{
 var maxLength = 5;
 var txt=document.getElementById("<%= RadTextBox1.ClientID %>");
 if(txt.value.length==maxLength)
  {

     __doPostBack("<%= RadGrid1.ClientID %>");
   }
}
</script>

Hope this helps
Shinu.
