    [CLOSED] Change event triggers when textfield modified in code-behind

    Hi there, I have setup a textfield on a form with a direct event triggering when field changes. I was expecting this event to trigger only when user changes the value manually on browser. Then I realized that if I change textfield value on code behind, the change trigger triggers the same. Is it there a way to disable trigger when textfield is modified at server side? I tried adding "return false;" to Before property of the event before assigning value but it did not work.

    Hi @jstifel,

    Yes, the Change event fires on any change.

    You can suspend the event on demand.

    <%@ Page Language="C#" %>
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    <script runat="server">
        protected void Set(object sender, DirectEventArgs e)
            this.TextField1.Text = "test";
    <!DOCTYPE html>
    <head runat="server">
        <title>Ext.NET v2 Example</title>
        <form runat="server">
            <ext:ResourceManager runat="server" />
            <ext:TextField ID="TextField1" runat="server">
                    <Change Handler="console.log('change');" />
            <ext:Button runat="server" Text="Set" OnDirectClick="Set" />

    Ok, I tried to call the SuspendEvent method finding there is only available one called SuspendEvents. I tried instead using this one and everything worked OK. I guess I may be running an older version of the library which does not include the SuspendEvent method. Anyway I solved the issue. Thank you very much.
    You can close the case now.

    Yes, the SuspendEvent appeared not so far ago.
