The ASP is two sets of controls: 1: textbox and button 2: dropdown list and button

The button click events hide(self) and show(other).

        <div class="control-group">
            <asp:Label ID="Label8" class="control-label" runat="server" Text="Company"> </asp:Label>
            <div class="row">
                <div class="col-md-12 ">
                    <asp:TextBox ID="txtCompanyName" class="control-label" runat="server" 
                        CssClass="form-control btn-group"
                    <asp:LinkButton ID="btnCompanySearch"
                        CssClass="btn btn-primary"
                        ToolTip="Company dropdown list" OnClick="btnCompanySearch_Click">
                        <span class="glyphicon glyphicon-search"></span>

                <div class="col-md-12">
                    <asp:DropDownList ID="ddlCompanyName" runat="server"
                        CssClass="form-control btn-group"
                        AutoPostBack="true" Visible="false"
                    <asp:LinkButton ID="btnCompanyText"
                        CssClass=" btn btn-primary"
                        ToolTip="Enter company manually" OnClick="btnCompanyText_Click">
                        <span class="glyphicon glyphicon-font"></span>


And the code behind...

protected void ddlCompany_SelectedIndexChanged(object sender, EventArgs e)
    txtCompanyName.Text = ddlCompanyName.SelectedValue == "-1" ? string.Empty: ddlCompanyName.SelectedValue; 
    btnCompanyText_Click(this, EventArgs.Empty);
protected void btnCompanySearch_Click(object sender, EventArgs e)
protected void btnCompanyText_Click(object sender, EventArgs e)
private void Search(bool bVal)
    txtCompanyName.Visible = bVal;
    btnCompanySearch.Visible = bVal;
    btnCompanyText.Visible = !bVal;
    ddlCompanyName.Visible = !bVal;
