    RE: About TextField Attribute Question

    Hi andyfoxcs !

    I have that problem too.

    What I've done so far is to add attributes to the texfield, so that way the control can be "readonly" without lose the value in an AjaxEvent.

    Here's what i've done:

    


protected void Page_Load(object sender, EventArgs e)


{
    if (!Page.IsPostBack)
    {
        // Read only attributes
        CoolTxtFld1.Attributes.Add("onkeypress", "return false;");
        CoolTxtFld1.Attributes.Add("onkeydown", "return false;");
    }
}

    Hope this helps.

    BUMP

    I'm converting my postback pages to all ajax events and I just spent 3 hours trying to figure this out. :)


    Is this a bug?

    RE: About TextField Attribute Question

    Can you post a complete (but simplified) .aspx code sample demonstating the problem?

    I tried the following with the latest code-base (v0.8.0) and it appears to work as expected.

    Example

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

<%@ Register assembly="Coolite.Ext.Web" namespace="Coolite.Ext.Web" tagprefix="ext" %>

<script runat="server">
*** protected void Button1_Click(object sender, AjaxEventArgs e)
*** {
******* this.Label1.Html = this.TextField1.Text;
*** }
</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 id="Head1" runat="server">
*** <title>HtmlEditor</title>
</head>
<body>
*** <ext:ScriptManager ID="ScriptManager1" runat="server" />
*** 
*** <form runat="server">
*** 
******* <ext:TextField ID="TextField1" runat="server" ReadOnly="true" />

******* <ext:Button runat="server" Text="Save">
*********** <AjaxEvents>
*************** <Click OnEvent="Button1_Click" />
*********** </AjaxEvents>
******* </ext:Button>
******* 
******* <ext:Label ID="Label1" runat="server" />

*** </form>
</body>
</html>
    Hope this helps.

    RE: About TextField Attribute Question



    *Geoffrey,

    I modified your example to add the additional step*where the value is dropped/lost.

    If this is fixed in v0.8.0 can you*think of*a work around till then?

    What's the ETA on v0.8.0 :)

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


<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %></p>


<script runat="server">
*** protected void Button1_Click(object sender, AjaxEventArgs e)
*** {
******* this.TextField2.Text = this.TextField1.Text;</p>


******* if (!String.IsNullOrEmpty(this.TextField2.Text))
******* {
*********** this.Label1.Html = this.TextField2.Text;
******* }
*** }
*** protected void Button2_Click(object sender, AjaxEventArgs e)
*** {
******* if (!String.IsNullOrEmpty(this.TextField2.Text))
******* {
*********** this.TextField3.Text = this.TextField2.Text;
******* }
******* this.Label1.Html = this.TextField2.Text + " test";
*** }
</script></p>
