Solution 1

[textboxID].Text = "whatever";

Put this in button click event handler.

Edit: Did not saw ASP.Net tag. :doh:

Since these are dynamically created controls, AFAIK you will have to recreate them on post back. While recreating, you can check if the postback is because of button click and if yes, set the text.

Solution 2

How about something like this:

C#

protected void Button1_Click ( object sender, EventArgs e )
{
    IEnumerable<TextBox> tboxes = this.Controls.OfType<TextBox> ();
    TextBox txtbx = tboxes.First<TextBox> ( t => t.ID == "txt1" );
    txtbx.Text = "something";
}

Please try:

In aspx.cs:

C#

public void addButton()
    {
        //setText() is a javasript function to set to 10 textboxes, examples
        /*
         * function setText()
         * {
         *      txt0.value = 'textbox0';
         *      txt1.value = 'textbox1';
         *      txt2.value = 'textbox2';
         *      txt3.value = 'textbox3';
         *      //Etc...
         * }
         */
        Response.Write("<input type="button"  önclick="setText();" value="Click Me" /> <br />");
    }
    
    public void addTextBoxes()
    {        
        for (int i = 0; i < 10; i++)
        {
            Response.Write("<input id="txt" + i.ToString() + "" type="textbox" /> <br />");
        }        
    }

In aspx:

<head  runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
        function setText(){
            form1.txt0.value = 'textbox0';
            form1.txt1.value = 'textbox1';
        }
    </script>
</head>
<body>
    <form id="form1"  runat="server">
        <%addButton(); %> 
        <%addTextBoxes(); %>
    </form>
</body>

Regards.
