    [CLOSED] TextField Hide

    Hi everybody,
    i have a trouble trying to hide a TextField in my Page.

    This is the Markup
    <ext:Button ID="BtnItaliano" runat="server" Text="Italiano" Icon="FlagIt">
    <Listeners>
        <Click Handler="Coolite.AjaxMethods.LinguaItaliano();" />
    </Listeners>
</ext:Button>
<ext:Button ID="BtnInglese" runat="server" Text="Inglese" Icon="FlagEngland">
    <Listeners>
        <Click Handler="Coolite.AjaxMethods.LinguaInglese();" />
    </Listeners>
</ext:Button>




<ext:TextField ID="TxtTitolo" runat="server"  />
<ext:TextField ID="TxtTitoloEn" runat="server" Visible="false" />
    This is the Code Behind
    [AjaxMethod]
public void LinguaInglese()
{
    TxtTitolo.SetVisible(false);
    TxtTitoloEn.SetVisible(true);
}

[AjaxMethod]
public void LinguaItaliano()
{
    TxtTitoloEn.SetVisible(false);
    TxtTitolo.SetVisible(true);
}
    This is my code, but pressing on the buttons, nothing changes...any suggests?
    I also try with TxtTitoloEn.Hide() but....nothing!

    Thanks,

    Hi Andrea,

    Change Visible="false" by Hidden="true" (just if you set Visible="false" then control is excluded form render and you can't manipulate it during ajax event)

    Hi vladsh,
    i've done what you suggest but nothing change...I still can't manipulate the visibility during an AjaxMethod.
    I also try to omit the Hidden=true properties in the markup making my page display it and clicking on the button the AjaxMethods try to hide it but nothing...

    i've try:

    TxtTitolo.Hidden = True;
    TxtTitolo.Visible = False;
    TxtTitolo.Hide();
    TxtTitolo.SetVisible(false);

    but none of this works.
    Plase help,

    Thanks,

    Hi Andrea,

    Do you use latest version?
    Here is my test case which works fine: 

    <%@ Page Language="C#" %>

<%@ Import Namespace="System.Collections.Generic" %>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"


"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Ext.IsAjaxRequest)
        {

        }
    }

    [AjaxMethod]
    public void LinguaInglese()
    {
        TxtTitolo.SetVisible(false);
        TxtTitoloEn.SetVisible(true);
    }

    [AjaxMethod]
    public void LinguaItaliano()
    {
        TxtTitoloEn.SetVisible(false);
        TxtTitolo.SetVisible(true);
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <ext:ScriptManager ID="ScriptManager1" runat="server" />
    
        <ext:Button ID="BtnItaliano" runat="server" Text="Italiano" Icon="FlagIt">
            <Listeners>
                <Click Handler="Coolite.AjaxMethods.LinguaItaliano();" />
            </Listeners>
        </ext:Button>
        <ext:Button ID="BtnInglese" runat="server" Text="Inglese" Icon="FlagEngland">
            <Listeners>
                <Click Handler="Coolite.AjaxMethods.LinguaInglese();" />
            </Listeners>
        </ext:Button>

        <ext:TextField ID="TxtTitolo" runat="server"  />

    RE: [CLOSED] TextField Hide

    Thank u vladimir for your examples, it works but don't...:).
    I mean that my problem was caused by having a revision of dlls that had some problems with AjaxMethods.
    Upgrading to the latest revision version mine and your examples perfectly works.
    Please mark this as solved.

    Thanks a lot,
