  You asked this same question here https://forums.asp.net/t/2130688.aspx?How+To+Retrive+QR+Code+Data+In+Textbox where you marked an answer as correct. 

  Did you try setting the focus on a textbox and scan?  What kind of scanner do you have?  Did you try contacting support for the scanner?

  Hi asp.ambur,

  According to your description and needs, about how to scan the QR code and show data in textbox, I make a sample, please check:

  Sample Code:

  You can install ZXing.Net using Package Manager console:

  Install-Package ZXing.Net 

  Page: 
  <div>
              <asp:Button ID="Show" runat="server" Text="Show Data" OnClick="Button1_Click" />
              <asp:TextBox ID="Content" runat="server"></asp:TextBox>
  </div>
  
  using ZXing;
  using System.Drawing;
  
   protected void Button1_Click(object sender, EventArgs e)
          {
              var reader = new BarcodeReader();
              String FullPath = MapPath(@"~\QRCode.jpg");
              var result = reader.Decode(new Bitmap(FullPath));
              Content.Text = result.Text;
          }

  Tested Image:

  

  Result:

  

  Best Regards,
