Custom Prompt MessageBox

  1. #1

    Custom Prompt MessageBox

    In the examples the prompt style message box calls a javascript function using

    Ext.Msg.Prompt("Name", "Please enter your name:", new JFunction { Fn = "showResultText" }).Show();
    I want to call an AjaxMethod where I will do some database updates. How do I get the text from the prompt. I was planning to use this syntax:-

    Ext.Msg.Prompt("Name", "Please enter the new username:", new MessageBox.ButtonsConfig
      Ok = new MessageBox.ButtonConfig { Handler = "Coolite.AjaxMethods.ChangeUsernameCallback('" + theText + '")", Text = "OK" },
      Cancel = new MessageBox.ButtonConfig { Text = "Cancel" }
    Where 'theText' would hold the value of the text from the prompt input.

        <script runat="server">
            <AjaxMethod(Type:=AjaxEventType.Load, ViewStateMode:=ViewStateMode.Exclude)> _
            Public Sub ChangeUsernameCallback(ByVal newname As String)
                'do some db updates
                'optionally alert
                Ext.MessageBox.Alert("Success", String.Format("Username changed successfully to '{0}'!", newname)).Show()
            End Sub
            Public Sub ServerSidePromptCallback(ByVal sender As Object, ByVal e As AjaxEventArgs)
                Ext.Msg.Prompt("Title", "Please enter new username:", New JFunction() With {.Fn = "function(btn, text) {if (btn == 'ok') {Coolite.AjaxMethods.ChangeUsernameCallback(text);}}"}).Show()
            End Sub
        <script type="text/javascript">
            function promptUsername() {
                Ext.Msg.prompt('Title', 'Please enter new username:', function(btn, text) {
                    if (btn == 'ok') {
        <asp:Panel runat="server" ID="pnlTools" Height="50px">
            <ext:Toolbar runat="server" ID="wsTools">
                    <ext:Button runat="server" Text="Client Prompt (faster)">
                            <Click Handler="Ext.Msg.prompt('Title', 'Please enter new username:', function(btn, text) {if (btn == 'ok') {Coolite.AjaxMethods.ChangeUsernameCallback(text);}})" />
                    <ext:Button runat="server" Text="Client Prompt (faster and cleaner)">
                            <Click Fn="promptUsername" />
                    <ext:Button runat="server" Text="Server Prompt">
                            <Click OnEvent="ServerSidePromptCallback">

    That works like a dream.

    Thanks for the extra code illustrating the different methods it was really appreciated. I will be revisiting some of my previous MessageBox/Callback code to make improvements.
