After clicking on the "Save" button only the "Update" Button will show. How do I do it on the form? 

<tr>
                <td>
                    <div runat="server" id="PrimaryBtnWrapper" class="btn-wrapper">
                    <telerik:RadButton RenderMode="Lightweight" ID="btnSave" runat="server" Skin="Silk" OnClick="btnSave_Click" Primary="true" 
                        Text=" Save " GroupName="GroupName1">
                    </telerik:RadButton>
                </div>
                </td>

                <td>
                    <div runat="server" id="PrimaryBtnWrapper1" class="btn-wrapper">
                    <telerik:RadButton RenderMode="Lightweight" ID="btnUpdate" runat="server" Skin="Office2007" OnClick="btnUpdate_Click" Primary="true" 
                        Text=" UPDATE " GroupName="GroupName1">
                    </telerik:RadButton>
                </div>
                </td>
            </tr>

From the .cs file, I create a method that checks if all the condition is true and then shows the 'save' button. if all the condition is false then show the 'update' button. And I call it Post back method.

protected void ButtonCheck()
    {
        if (txtAddress.Text != "" && txtEdu.Text != "" && txtContact.Text != "" && txtemail.Text != "")
        {
            btnSave.Style["display"] = "none";
        } 
        else if (txtAddress.Text == "" && txtEdu.Text == "" && txtContact.Text == "" && txtemail.Text == "")
        {
            btnUpdate.Style["display"] = "none";
        }
}
