[CLOSED] Read Only NumberField

I'm having trouble reading the current value of a NumberField set to readonly=true. I'm updating the number in the field with a button and direct event and then showing the results in an alert. When I click the Show button, I get the default value and not the value in the field. If the NumberField is set to readonly=false, it works fine. Please let me know if I'm missing something...code sample follows.

Thank you.

Code:

<head runat="server"> <title></title> <script runat="server" > Protected Sub Button1_Click(ByVal sender As Object, ByVal e As AjaxEventArgs) ScriptManager1.AddScript("Ext.Msg.alert('Alert', '" & numNet.Number & "');") End Sub Protected Sub Button2_Click(ByVal sender As Object, ByVal e As AjaxEventArgs) numNet.Number = 5.12 End Sub </script> </head> <body> <form id="form1" runat="server"> <div> <ext:ScriptManager ID="ScriptManager1" runat="server" /> <ext:NumberField ID="numNet" runat="server" FieldLabel="Net" Width="100" AllowDecimals="true" TrimTrailedZeros="False" ReadOnly="True" /> <ext:Button ID="Button1" runat="server" Text="Show"> <AjaxEvents> <Click OnEvent="Button1_Click" /> </AjaxEvents> </ext:Button> <ext:Button ID="Button2" runat="server" Text="Set Number"> <AjaxEvents> <Click OnEvent="Button2_Click" /> </AjaxEvents> </ext:Button> </div> </form> </body>

Don't use numNet.Number to set the value, use numNet.value = 5.12

Hi iansriley,

Yes, ljankowski is right, please use the NumberField's Value property.

Example

Code:

numNet.Value = 5.12

Just getting a blank (empty string) now. Any other possibilities?

Code:

<script runat="server" > Protected Sub Button1_Click(ByVal sender As Object, ByVal e As AjaxEventArgs) ScriptManager1.AddScript("Ext.Msg.alert('Alert', '" & numNet.Value & "');") End Sub Protected Sub Button2_Click(ByVal sender As Object, ByVal e As AjaxEventArgs) numNet.Value = 5.12 End Sub </script>

You could manually send a NumberField's value as extra parameter.

Example

Code:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As AjaxEventArgs) Ext.Msg.Alert("Alert", e.ExtraParams.Item("value")).Show() End Sub ... <ext:Button ID="Button1" runat="server" Text="Show"> <AjaxEvents> <Click OnEvent="Button1_Click"> <ExtraParams> <ext:Parameter Name="value" Value="numNet.getValue()" Mode="Raw" /> </ExtraParams> </Click> </AjaxEvents> </ext:Button>

That appears to work well; thank you for the workaround. I will consider this issue solved but out of curiosity, was this a bug in 8.2 that will be fixed in 1.0?

Yes, in Ext.Net it works very well with any combination of properties Value, Number, Text, ReadOnly.

By the way we strongly recommend to migrate on Ext.Net 1.0.
You would be pleasantly surprised by the flexibility and power of this toolkit's version.

Hi,

The following example demonstrates your sample using v1.0 code.

Example

Code:

<%@ Page Language="C#" %> <%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %> <script runat="server"> protected void Button1_Click(object sender, DirectEventArgs e) { X.Msg.Alert("Alert", this.NumberField1.Number).Show(); } protected void Button2_Click(object sender, DirectEventArgs e) { this.NumberField1.Number = 5.12; } </script> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Ext.NET Example</title> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:NumberField ID="NumberField1" runat="server" FieldLabel="Net" ReadOnly="true" /> <ext:Button runat="server" Text="Set Number" OnDirectClick="Button2_Click" /> <ext:Button runat="server" Text="Show" OnDirectClick="Button1_Click" /> </form> </body> </html>

Hope this helps.
