your question is not clear. Value of selected item of dropdown can be taken from
ddlVndrName.SelectedItem.Value
if you need to show the selected value of ddl in textbox
TextBox1.Text = Convert.Tostring(ddlVndrName.SelectedItem.Value);
if you need to process something based on the selected value and display results in a textbox:
<asp:DropDownList ID="ddlVndrName" runat="server" AutoPostBack="True" onselectedindexchanged="ddlVndrName_SelectedIndexChanged"
protected void ddlVndrName_SelectedIndexChanged(object sender, EventArgs e)
{
string selectedValue = Convert.Tostring(ddlVndrName.SelectedItem.Value)
TextBox1.Text = ProcessText( selectedValue);
}
if you need to create dynamic text boxes based on selected value
