    [CLOSED] TextField with right buttons

    Hi,

    I'm creating controls dynamically :

    I'm getting javascript error below When I have created TextField with right buttons :

    Unable to get property 'writeTo' of undefined or null reference

    Here is my code :

    Ext.Net.TextField extTextField1 = new Ext.Net.TextField();
                                            extTextField1.ID = fieldList[i].Name;
                                            extTextField1.EnableViewState = true;
    
                                            Ext.Net.Button extBtn = new Ext.Net.Button();
                                            extBtn.ID = "extbtn" + fieldList[i].Name;
                                            extBtn.Icon = Ext.Net.Icon.Add;
                                            extTextField1.RightButtonsShowMode = Ext.Net.ButtonsShowMode.Always;
                                            extTextField1.RightButtons.Add(extBtn);
    
    Form1.controls.add(extTextField1);
    Thanks,

    Hello, Vamsi!

    I tried to reproduce your piece of code here adding a surrounding context that would run in your code part.

    I could run it. The problem is that no problem happened at all! Are you using SVN version or downloaded 3.0/3.1 version? Which one would be it?

    Here's the code I've come up with that is working:
    The .aspx.cs:
        public partial class _59539_rightClickIssue : System.Web.UI.Page
        {
            public class NmVl
            {
                public string Name;
                public string Value;
            }
    
            protected void Page_Load(object sender, EventArgs e)
            {
                var fieldList = new List<NmVl>();
                fieldList.Add(new NmVl { Name = "A", Value = "1" });
                fieldList.Add(new NmVl { Name = "B", Value = "2" });
                fieldList.Add(new NmVl { Name = "C", Value = "3" });
    
                for (int i = 0; i < 3; i++)
                {
                    Ext.Net.TextField extTextField1 = new Ext.Net.TextField();
                    extTextField1.ID = fieldList[i].Name;
                    extTextField1.EnableViewState = true;
    
                    Ext.Net.Button extBtn = new Ext.Net.Button();
                    extBtn.ID = "extbtn" + fieldList[i].Name;
                    extBtn.Icon = Ext.Net.Icon.Add;
                    extTextField1.RightButtonsShowMode = Ext.Net.ButtonsShowMode.Always;
                    extTextField1.RightButtons.Add(extBtn);
    
                    tfc.Add(extTextField1);
                }
            }
        }
    <%@ Page Language="C#" %>
    
    <!DOCTYPE html>
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
            <ext:ResourceManager runat="server" ScriptMode="Debug" SourceFormatting="true" />
            <ext:TextField runat="server" Text="I got some text here. :P" ID="TextField1" />
            <ext:Container runat="server" ID="tfc" />
        </div>
        </form>
    </body>
    </html>
    And the shown result is this:

    Can you show us in which context, or adapt the code above to reproduce the error you're experiencing?

    I hope we can get this sorted out soon.

    Hi,

    From your sample is not clear which Panel do you use (Ext.Net.Panel or ASP Panel)
    Please post a sample which does not require any changes from our side

    Also please see the following samples are demonstrated how dynamically create controls during direct event

    Thank you Valdmir,


    I'm using AspPanel but I can't replace to Ext:panel.

    We have already base layout and we are replacing aspcontols to extcontrols.

    Please give me solution with out replacing the asp:panel.

    Thanks,
    Vamsi.

    Yes, please provide a runnable test case. You can put the code behind directly into the .aspx page wrapping in
    <script runat="server">
        // code behind
    </script>
