How to clear asp net input fields?

Question

ASP.NET

Good afternoon. I have input fields (textBox's) to send information to a database. But after sending the data remains in the fields. Standard jquery scripts for clearing the form do not work here, and the html form cannot send data to the database. The reset button works, but only until the form is submitted. After sending, it no longer clears the fields. Maybe there is a solution.? Below is the code.

<asp:DropDownList ID="DropDownList1" runat="server">

        <asp:ListItem>умент</asp:ListItem>

        <asp:ListItem>т</asp:ListItem>

        <asp:ListItem>я</asp:ListItem>

        <asp:ListItem>умент</asp:ListItem>

        <asp:ListItem>умент</asp:ListItem>

        <asp:ListItem>Пневматический инструмент</asp:ListItem>

    </asp:DropDownList>

    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

    <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

    <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>

    <asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>

                  

 

 

    <asp:Button ID="Button2" runat="server" Text="Отправить"/>

Sending to the database on any
