Introduction

In this article I will explain about how to create a Helper Class for DataGridView in Winform Application. In one of my web project I want to create the datagridview Dynamically at runtime. When i start my project I was looking for a Helper Class for DataGridView and used Google for get one Helper Class. But i couldn’t found any helper class for DataGridView. So I plan to create a Helper Class for DataGridView. As a result I have created a helper class for DataGridView. I want to share my helper class with others so that they can use my class in there project and make a code simple and easy.

WHY WE NEED HELPER CLASS:

Helper Class will make our code part Simple and Standard.
All the Events of DataGridview can be defined in the helperClass . In our form we can call the method from helper class and make our code simple.
One Time Design in Class can be used for the whole project.
This will be useful if we change design only in Class File and no need to redesign in each form.

WHAT WE HAVE IN HELPER CLASS:

Design your Datagridview ,Add the Datagridview to your controls like Panel,Tab or in your form.
Bound Column
CheckBox Column
TextBox Column
Numeric TextBox Column
ComboBox Column
DateTimePicker Column
Button Column
Colour Dialog Column
DataGridView Events like CellClick,CellContentClick and etc.

Here is an sample with Color Dialog from button Column.

Using the code

First we can start with the helper class and then we can see how to use the helper class in Winform. In my helper class I have the fallowing function to make the design and bind simple.

Layout
Generategrid
Templatecolumn
NumeriTextboxEvents
DateTimePickerEvents
DGVClickEvents
colorDialogEvents

We can see few important functions of the class and then i will paste my full class Code here.

Layout: This method will be setting the BackgroundColor, BackColor,AllowUserToAddRows and etc for the datagridView. In this method we pass our Datagridview and setting all the design part for grid.

  //Set all the DGV layout
        #region Layout
        
        public static void Layouts(DataGridView ShanuDGV, Color BackgroundColor, Color RowsBackColor, Color AlternatebackColor, Boolean AutoGenerateColumns, Color HeaderColor, Boolean HeaderVisual, Boolean RowHeadersVisible, Boolean AllowUserToAddRows)
        {
            //Grid Back ground Color
            ShanuDGV.BackgroundColor = BackgroundColor;

            //Grid Back Color
            ShanuDGV.RowsDefaultCellStyle.BackColor = RowsBackColor;

            //GridColumnStylesCollection Alternate Rows Backcolr
            ShanuDGV.AlternatingRowsDefaultCellStyle.BackColor = AlternatebackColor;

            // Auto generated here set to tru or false.
            ShanuDGV.AutoGenerateColumns = AutoGenerateColumns;
          //  ShanuDGV.DefaultCellStyle.Font = new Font("Verdana", 10.25f, FontStyle.Regular);
           // ShanuDGV.ColumnHeadersDefaultCellStyle.Font = new Font("Calibri", 11, FontStyle.Regular);

            //Column Header back Color
            ShanuDGV.ColumnHeadersDefaultCellStyle.BackColor = HeaderColor;

            //header Visisble
            ShanuDGV.EnableHeadersVisualStyles = HeaderVisual;
            
            // Enable the row header
            ShanuDGV.RowHeadersVisible = RowHeadersVisible;

            // to Hide the Last Empty row here we use false.
            ShanuDGV.AllowUserToAddRows = AllowUserToAddRows;
        }
        #endregion

Generategrid: In this method we pass our Datagridview and set the height,width,position and bind the datagriview to our selected control.

 public static void Generategrid(DataGridView ShanuDGV, Control cntrlName, int width, int height, int xval, int yval)
        {
            ShanuDGV.Location = new Point(xval, yval);
            ShanuDGV.Size = new Size(width, height);
            //ShanuDGV.Dock = docktyope.
            cntrlName.Controls.Add(ShanuDGV);
        }

TemplateColumn: This is the important method in the helperclass,Here we pass the Datagriview and define the column as Bound ,Checkbox,Textbox DateTimePicker and etc.Here we set each column width, Alignment, Visibility, BackColor,Font Color and etc.

public static void Templatecolumn(DataGridView ShanuDGV, ShanuControlTypes ShanuControlTypes, String cntrlnames, String Headertext, String ToolTipText, Boolean Visible, int width, DataGridViewTriState Resizable, DataGridViewContentAlignment cellAlignment, DataGridViewContentAlignment headerAlignment, Color CellTemplateBackColor, DataTable dtsource, String DisplayMember, String ValueMember, Color CellTemplateforeColor)

NumerictextBoxEvent: In this method we pass the Datagridview and list of ColumnIndex which need to be set as NumbericTextbox Column.Using the EditingControlShowing Event of Gridview ,I check for all the columns which need to be accept only numbers from the textbox.

        }

DatagridView helperClass Full Source Code : Here is the full source code of the Datagridview helper class. I have created all the necessary methods which need to be used. if user need more functions they can add those functions as well here in this class and use in your projects.

Now let’s see how to use this Helper Class in our winform project.

1) Add the helperClass file in to your project.

2) In your form Load call a Method to create your Datagridview Dynamically and call the functions to design, bind and set the each column of your grid.

Here we can see I have created a method called "generatedgvColumns” and called this method in my Form Load Event.

Collapse | Copy Code

  public void generatedgvColumns()
        {

            //First generate the grid Layout Design
            ShanuDGVHelper.Layouts(shanuDGV, Color.LightSteelBlue, Color.AliceBlue, Color.WhiteSmoke, false, Color.SteelBlue, false, false, false);

            //Set Height,width and add panel to your selected control

" ShanuDGVHelper.Layouts()" this method is used to set the layout of grid like autogenrated or not, BackgroundColor, AlternatebackColor, RowHeadersVisible and etc.

"ShanuDGVHelper.Generategrid()" this method is used to set the Height, Width and add the datagridview to our selected control, for example here i have added the DGV to a panel control.

" ShanuDGVHelper.Templatecolumn" this method is used to define our Column type as Checkbox ,Textbox, Combobox and etc. To this method we pass the Column Name,Column Header Text,Column Width,Column Back Color and etc.
