Hi, I am playing arround with the WebNumericEdit Control. See below for the configuration:
<igtxt:WebNumericEdit ID="WebNumericEdit1" runat="server" ReadOnly="true" BackColor="transparent" BorderStyle="None" Font-Size="Large" HorizontalAlign="Center" ForeColor="#404040" AutoPostBack="true"><SpinButtons Display="OnRight" SpinOnReadOnly="true" Width="20" /></igtxt:WebNumericEdit>
I would like to perform an AutoPostBack when the value has been changed by the SpinButtons. But it doesn't seem to work. I even set the AutoPostBack to True and I have the following code on the server side:
Protected Sub WebNumericEdit1_ValueChange(ByVal sender As Object, ByVal e As Infragistics.WebUI.WebDataInput.ValueChangeEventArgs) Handles WebNumericEdit1.ValueChange ' ... Code ... 'End Sub
What am I missing here?Note that I set the WebNumericEdit to Read-Only and that I would like to use the SpinButtons to count one value up or down, and every time I count one value up or down, I would like to have a postback.
Thanks.
Thank you Viktor. That works fine!
Hi,
Since that thread is about WebDateTimeEdit and you mentioned InvalidValue, but not InvalidValueEntered, I assume that you ask about WebDateTimeEdit, but not about WebDateTimeEditor.
From point of javascript Date and server DateTime object, the date 09/09/9999 is valid. If you want to prevent entering similar date, then you may set Min/MaxValue properties or process ValueChange and "fix" resulting value dynamically. Below, I show example which fills up year field is it missing and sets null if user entered year larger than 9000.
<script type="text/javascript">function invalidValue(editor, oEvent){ var month = oEvent.month; var year = oEvent.year; var day = oEvent.day; if(day != null && day > 0 && month != null && month >= 0) { var date = null; if(year < 0) oEvent.date = new Date(2010, month - 1, day); else if(year > 9000) oEvent.date = null; }}</script><igtxt:WebDateTimeEdit ID="WebDateTimeEdit1" runat="server" MinValue="1955-02-19" MaxValue="2200-01-31"> <ClientSideEvents InvalidValue="invalidValue" /></igtxt:WebDateTimeEdit>
I gave the Infragistics controls yet another chance to work properly today.
this time - WebDateTimeEditor.
I tell it to add the InvalidValue client side event.
I get the "failure to add SCRIPT block to page" error.
I'd like to know how to get around this too. Maybe I'll try making this work again some day.
All I really care to see it do is not allow an invalid date (like '09/09/9999'. I thought that might be easy.
Victor,
When I try to add client side events the way you suggested. I get "failure to add SCRIPT block". I know I can type in the javascript first then just
set the clientside event but the problem is I don't know the parameters. I was hoping (and based on your reply)
the IDE will supply the parameters for me.
Is there a way to fix the failure to add SCRIPT block problem?
To add a handler to a client event at visual design, you may type-in name of function directly, or you may use "Add new handler.." option. In this case editor will also generate for you javascript function with parameters.
<igtxt:WebNumericEdit ID="WebNumericEdit1" runat="server" ReadOnly="true" BackColor="transparent" BorderStyle="None" Font-Size="Large" HorizontalAlign="Center" ForeColor="#404040" AutoPostBack="true"><SpinButtons Display="OnRight" SpinOnReadOnly="true" Width="20" /> <ClientSideEvents Spin="WebNumericEdit1_Spin" /></igtxt:WebNumericEdit>
A change in source codes (fix) becomes available in public service releases in 1-2 months. I can not say exact date.
