Cannot get Text from TextField

[faridhajnal]

Please help, I have a simple example:

<ext:ResourceManager runat="server" />
    <ext:Viewport runat="server">
        <Items>  <ext:TextField runat="server" ID="Txt1" FieldLabel="Insert"/>
                 <ext:TextArea runat="server" ID="Area1" FieldLabel="Text" />
                 <ext:Button runat="server" ID="Btn1" Text="Click" UI="Primary"  OnDirectClick="Do"></ext:Button>
                 <ext:Button runat="server" ID="Button1" Text="Click" UI="Primary"  OnDirectClick="getText"></ext:Button>
        </Items>
    </ext:Viewport>

and in code behind I have the following:

protected void Do(object sender, EventArgs e)
{
    string b = Txt1.Text.ToString();
    string c = Area1.Text;
}

Nor string neither c save the value from the text field, how can I obtain it if it is entered by the user and after clicking the button ? Please help, I am desperate...

Hello @faridhajnal! Welcome to Ext.NET forums!

This does not work because the code behind does not have control over page contents once the page has already sent to the client.

In order to be able to fetch what's on the page during an AJAX call (direct method/event like you are doing), you have to actually pass these arguments.

Look at this example: DirectMethod Overview

The third case shown in the example illustrates what you likely need, passing a form values to a code behind method:

<script runat="server">
    [DirectMethod]
    public void LogCompanyInfo(string name, int count)
    {
        string template = string.Concat("{0} has approximately {1} employees.");
        string[] employees = new string[4] { "1-5", "6-25", "26-100", "100+" };
        
        this.Label3.Text = string.Format(template, name, employees[count]);
    }
</script>

<ext:Button runat="server" Text="Submit">
    <Listeners>
        <Click Handler="App.direct.LogCompanyInfo('Ext.NET, Inc.', 0);" />
    </Listeners>
</ext:Button>

I hope this helps!
