    <div>

        <asp:Label ID="Label1" runat="server" Text="Enter value" style="top: 251px; left: 374px; position: absolute; height: 19px; width: 77px"></asp:Label>

        <asp:TextBox ID="searchText" runat="server" style="top: 244px; left: 460px; position: absolute; height: 22px; width: 169px"></asp:TextBox>

        <asp:Button ID="searchBtn" runat="server" Text="Search" style="top: 243px; left: 645px; position: absolute; height: 26px; width: 56px" OnClick="searchBtn_Click" />

        {

            string strTxt = string.Empty;

            StringBuilder strBuild = new StringBuilder();

            strBuild.Append("https://www.google.com/search?q=");

            if (searchText.Text != string.Empty)

            {

                strTxt = searchText.Text.Replace(' ', '+');

                strBuild.Append(strTxt + ' ' + '+');

            }

            string url = strBuild.ToString();

            Response.Redirect(url, false);

        }

        catch (Exception ex)

        {

            Response.Redirect(ex.ToString());

        }
