How to use the TaskManager control of the Visible Properties Button?

this is My Code:

<ext:Button ID="btnJATS" runat="server" Text="Please Click" Icon="Accept" Visible="false">
    <AjaxEvents>
        <Click OnEvent="btnJATS_Click" >
            <EventMask ShowMask="true" Msg="361°..." />
        </Click>
    </AjaxEvents>
</ext:Button>

<ext:TaskManager ID="TaskManager1" runat="server">
    <Tasks>
        <ext:Task TaskID="UpCenter" Interval="6000">
            <AjaxEvents>
                <Update OnEvent="RefreshCenter">
                </Update>
            </AjaxEvents>
        </ext:Task>
    </Tasks>
</ext:TaskManager>

protected void RefreshCenter(object sender, AjaxEventArgs e)
{
    string Isok = getIsok();
    if (Isok == "ok")
    {
        btnJATS.Visible = true;
    }
    else
    {
        btnJATS.Visible = false;
    }
}

</PRE></PRE>

Hi wkcode,

You should only have to change the .Visible property to .Hidden.

Then you can tighten up your event handler as well.

Example

protected void RefreshCenter(object sender, AjaxEventArgs e)
{
    btnJATS.Hidden = !(getIsok() == "ok");
}

Hope this helps.
