Friend, on button click event, take the value of both text box like TextBox1.Text and convert them into double/int data type, multiply both the textbox values and assign the value on label as "Label1.Text =(Convert.ToInt(TextBox1.Text)*Convert.ToInt(TextBox2.Text)).ToString();"

Thanks,

<body>
    <form id="form1" runat="server">
    <div>
    <asp:label id="lblNumber1" runat="server" text="Enter first value:" xmlns:asp="#unknown"></asp:label>
    <asp:textbox id="txtNumber1" runat="server" xmlns:asp="#unknown"></asp:textbox>
    <br />
    <asp:label id="lblNumber2" runat="server" text="Enter second value:" xmlns:asp="#unknown"></asp:label>
    <asp:textbox id="txtNumber2" runat="server" xmlns:asp="#unknown"></asp:textbox>
    <br />
    <asp:button id="btnMultiplication" runat="server" text="Multiplication" onclick="OnBtnMultiplicationClick" xmlns:asp="#unknown"></asp:button>
    <br /><asp:label id="lblMultiplication" runat="server" xmlns:asp="#unknown"></asp:label>
    </div>
    
    </form>
</body>

Now on code behind (test.aspx.cs):
----------------------------------

 protected void OnBtnMultiplicationClick(object sender, EventArgs e)
        {
            int num1=Convert.ToInt32(txtNumber1.Text);
            int num2 = Convert.ToInt32(txtNumber2.Text);
            lblMultiplication.Text = (num1 * num2).ToString();
 
        }
**Validation is not done so check for Null or empty value.
