How To Make a Single Row of DataGridview Bold Using C#.Net in Windows Application

Whenever create a windows application on that case we always face some situation where we needed to display record in grid form and wanted to highlight a single row . So in this application I will show you how you can bind a datagridview control in your windows application using C#. In this I will use ms access database to access the data and  highlight a single row.

In my previous article I have shown your how you can bind a gridview control in asp.net application check the article Binding Gridview By Access DataBase Using C#.Net in Asp.Net, Bind DataGridView In Windows Application Using C#

Some of my previous windows and C# .net application are as follows:  How to Minimize an Application to the Taskbar Tray in C#.Net | System Tray Application C#, Email Validation in Windows Application C#.Net and VB.Net | Validating Email ID in TextBox in C# .Net, Displaying More than One Month in the Windows Forms MonthCalendar Control Using C#.Net.

My listbx related articles are as follows: Remove Selected Item From Listbox C#.Net and VB.net, How to add/move multiselected items from one listbox to another listbox in C#.Net and VB.Net | C# multiple selection listbox move Using C#.Net, Transfer Listbox Items to Another Listbox Using C#.Net and VB.Net | How to Move List Box Items to another List Box in C#.

Now for this article first we will create a new windowsapplication and add a DataGridView Control in it.

Now check the below code

C#.Net

using System; using System.Collections.Generic; using System.Data; using System.Data.OleDb; using System.Drawing; using System.Windows.Forms; namespace DemoWindowsApplication {        /// <summary>        /// Description of MainForm.        /// </summary>        public partial class MainForm : Form        {                public string connectionstring ="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=bookstore.mdb;Persist Security Info=False;";               /// <summary>               /// Default constructor for main form               /// </summary>               public MainForm()               {                      InitializeComponent();               }                                          void MainFormLoad(object sender, EventArgs e)               {                      DataTable _objdt = new DataTable();             _objdt = GetDataFromDataBase();             if (_objdt.Rows.Count > 0)             {                 dataGridView1.DataSource = _objdt;                 //Code to hilight the row                 foreach (DataGridViewRow row in dataGridView1.Rows)                     if (Convert.ToInt32(row.Cells[2].Value) == 1903)                     {                       row.DefaultCellStyle.Font = new Font("Arial", 10, FontStyle.Bold);                     }             }                            }                /// <summary>         /// Function for binding retriving the data from database         /// </summary>         /// <returns></returns>         public DataTable GetDataFromDataBase()         {             DataTable _objdt = new DataTable();             string querystring = "select author_name,title,publication_year from Books;";             OleDbConnection _objcon=new OleDbConnection(connectionstring);             OleDbDataAdapter _objda = new OleDbDataAdapter(querystring, _objcon);             _objcon.Open();             _objda.Fill(_objdt);             return _objdt;         }        } }

VB.Net

Imports System Imports System.Collections.Generic Imports System.Data Imports System.Data.OleDb Imports System.Drawing Imports System.Windows.Forms Namespace DemoWindowsApplication     ''' <summary>     ''' Description of MainForm.     ''' </summary>     Partial Public Class MainForm         Inherits Form         Public connectionstring As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=bookstore.mdb;Persist Security Info=False;"         ''' <summary>         ''' Default constructor for main form         ''' </summary>         Public Sub New()             InitializeComponent()         End Sub         Private Sub MainFormLoad(ByVal sender As Object, ByVal e As EventArgs)             Dim _objdt As New DataTable()             _objdt = GetDataFromDataBase()             If _objdt.Rows.Count > 0 Then                 dataGridView1.DataSource = _objdt                 'Code to hilight the row                  For Each row As DataGridViewRow In dataGridView1.Rows                  If Convert.ToInt32(row.Cells(2).Value) = 1903 Then                     row.DefaultCellStyle.Font = New Font("Arial", 10, FontStyle.Bold)                   End If                 Next             End If         End Sub         ''' <summary>         ''' Function for binding retriving the data from database         ''' </summary>         ''' <returns></returns>         Public Function GetDataFromDataBase() As DataTable             Dim _objdt As New DataTable()             Dim querystring As String = "select author_name,title,publication_year from Books;"             Dim _objcon As New OleDbConnection(connectionstring)             Dim _objda As New OleDbDataAdapter(querystring, _objcon)             _objcon.Open()             _objda.Fill(_objdt)             Return _objdt         End Function     End Class End Namespace

In above code below mention code is used for highlighting the row.

//Code to hilight the row                 foreach (DataGridViewRow row in dataGridView1.Rows)                     if (Convert.ToInt32(row.Cells[2].Value) == 1903)                     {                       row.DefaultCellStyle.Font = new Font("Arial", 10, FontStyle.Bold);                     }

Now in above code first we have created a function whose return type is DataTale and on page load we have bind the datagridview control.

Now run the application
