I have declared a button in my CreateChildControls method in my web part page:

TableCell updateCell = new TableCell();
        Update = new Button();
        Update.Text = "Update";
        Update.OnClientClick += new EventHandler(Update_OnClick);

This is the eventhandler that I created:

    private void Update_OnClick(object sender, EventArgs e)
        if (_TYPE == "FIXED")
            Item["Retail"] = txtFixedRetail.Text;

However JScript throws an error:

Microsoft JScript runtime error: 'System' is undefined

And produces this in the HTML:

<td><input type="submit" name="ctl00$m$g_c260f907_31c1_436b_b99e_9bf79427625c$ctl11"     value="Update" onclick="System.EventHandler;" /></td>

Why is the eventhandler that I declared in the WebPart not passing to the Page? Do I have to push all events to the Client?


Button.OnClientClick is assigning JavaScript to run in the browser

Button.Click is for Server side event handling
