Using ASP.NET / HTML buttons

I have a form with two buttons:

XML

<form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />
        <input type="button" onclick="criarNota();" value="Criar Nota" />
        <input type="button" onclick="botaoCarregarNotas();" value="Carregar Notas" />

    </form>

But I would like that the second buttons "Carregar Notas", only appears after clicking on "Criar Nota" button.

Is that possible ?

Hi
The code will look some thing like this

XML

<form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />
        <input type="button" id="criarNota" onclick="criarNota();" value="Criar Nota" />
        <input type="button" id="botaoCarregarNotas" onclick="botaoCarregarNotas();" style="display:none;" value="Carregar Notas" />
    </form>

Now the Javascript function will look like

function criarNota(){
document.getElementById("botaoCarregarNotas").style.display = "block";
}

Thanks
Hope this helps

Yes, very much possible.

First of all, define ID field for both the buttons.

Set the style:display property of button with text "Carregar Notas" as none to begin with. This would render the button on the page but keep it hidden.

Now, onclick of button with text "Criar Nota", call client side Javascript method "criarNota()"

In this method, get the other button and just set the display property to block and you are done. Try!
