Step 3: Design the UI
Enhance the Index page by editing the index.cshtml
file. Apply custom styling:
<style>
body {
font-family: 'Poppins', sans-serif;
}
/* More CSS styles omitted for brevity */
</style>
<style>
body {
font-family: 'Poppins', sans-serif;
}
/* More CSS styles omitted for brevity */
</style>
Adding a Welcome Message:
<h1 class="text-center mb-4" style="color:#004b9b">Welcome to Barcode Generator</h1>
<div class="svg-container text-center">
<img src="~/images/logo.svg" class="barcode-logo" alt="Barcode" />
</div>
<h1 class="text-center mb-4" style="color:#004b9b">Welcome to Barcode Generator</h1>
<div class="svg-container text-center">
<img src="~/images/logo.svg" class="barcode-logo" alt="Barcode" />
</div>
Structuring the Main Content:
<div class="container">
<div class="row justify-content-center">
<!-- Form and Image Column will go here -->
</div>
</div>
<div class="container">
<div class="row justify-content-center">
<!-- Form and Image Column will go here -->
</div>
</div>
Design Input Form:
Include the form to collect user input for barcode generation:
<div class="col-md-6 divider col-padding">
<form method="post" enctype="multipart/form-data">
<!-- Form elements omitted for brevity -->
<button type="submit" asp-page-handler="Upload" class="btn btn-primary btn-block">Generate Barcode</button>
</form>
<div id="messageContainer">
<span id="message" style="color:green;">@Html.Raw(Model.Message)</span>
</div>
</div>
<div class="col-md-6 divider col-padding">
<form method="post" enctype="multipart/form-data">
<!-- Form elements omitted for brevity -->
<button type="submit" asp-page-handler="Upload" class="btn btn-primary btn-block">Generate Barcode</button>
</form>
<div id="messageContainer">
<span id="message" style="color:green;">@Html.Raw(Model.Message)</span>
</div>
</div>
Image Column:
For displaying and downloading the generated barcode:
<div class="col-md-6 image-padding">
<div id="imageContainer">
<!-- Image and download button elements omitted for brevity -->
</div>
</div>
<div class="col-md-6 image-padding">
<div id="imageContainer">
<!-- Image and download button elements omitted for brevity -->
</div>
</div>
Scripts:
Add functionality to handle input and download actions using jQuery:
@section Scripts {
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<script>
$(document).ready(function () {
// jQuery code omitted for brevity
});
</script>
}
@section Scripts {
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<script>
$(document).ready(function () {
// jQuery code omitted for brevity
});
</script>
}
Step 4: Writing Functional Code
Define Color:
At the top of your index.cshtml
file, add:
using Color = IronSoftware.Drawing.Color;
using Color = IronSoftware.Drawing.Color;
IRON VB CONVERTER ERROR developers@ironsoftware.com
Barcode Colors Enum:
Define available colors for barcodes:
public enum BarcodeColors
{
AliceBlue,
AntiqueWhite,
Aqua,
Aquamarine,
Azure,
Beige,
Bisque
// And others...
}
public enum BarcodeColors
{
AliceBlue,
AntiqueWhite,
Aqua,
Aquamarine,
Azure,
Beige,
Bisque
// And others...
}
Public Enum BarcodeColors
AliceBlue
AntiqueWhite
Aqua
Aquamarine
Azure
Beige
Bisque
' And others...
End Enum
Barcode Types Enum:
Define available types of barcodes:
public enum BarcodeTypes
{
Aztec,
Codabar,
// Other barcode types...
}
public enum BarcodeTypes
{
Aztec,
Codabar,
// Other barcode types...
}
Public Enum BarcodeTypes
Aztec
Codabar
' Other barcode types...
End Enum
Helper Functions:
Convert enums to color and barcode encoding:
private Color EnumToColor(BarcodeColors colorEnum) { /* Conversion logic */ }
private BarcodeWriterEncoding GetBarcodeEncoding(BarcodeTypes barcodeType) { /* Encoding logic */ }
private Color EnumToColor(BarcodeColors colorEnum) { /* Conversion logic */ }
private BarcodeWriterEncoding GetBarcodeEncoding(BarcodeTypes barcodeType) { /* Encoding logic */ }
Private Function EnumToColor(ByVal colorEnum As BarcodeColors) As Color
End Function
Private Function GetBarcodeEncoding(ByVal barcodeType As BarcodeTypes) As BarcodeWriterEncoding
End Function
OnPostUpload Function:
Handle form submission for barcode generation:
public JsonResult OnPostUpload(string barcodeText, string barcodeType, int? maxWidth, int? maxHeight, string barcodeColor)
{
// Function logic...
}
public JsonResult OnPostUpload(string barcodeText, string barcodeType, int? maxWidth, int? maxHeight, string barcodeColor)
{
// Function logic...
}
Public Function OnPostUpload(ByVal barcodeText As String, ByVal barcodeType As String, ByVal maxWidth? As Integer, ByVal maxHeight? As Integer, ByVal barcodeColor As String) As JsonResult
' Function logic...
End Function
Layout Editing:
Edit \_Layout.cshtml
for a minimalist design:
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Head contents omitted for brevity -->
</head>
<body>
<div class="container">
<main role="main" class="pb-3">
