Hi
I m completely new to C#.Net, and I couldnt find " RowCreated" Event Handler for my DataGridView.

So, I created a new Event Handler, but now I dont know how to call it.

pls help me out... Below is my code ...

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Web.UI.WebControls;

namespace DgvColumnHeaderMerge
{
    public partial class DgvColumnHeaderMerge : Form
    {
        public event GridViewRowEventHandler RowCreated;

        public DgvColumnHeaderMerge()
        {
            InitializeComponent();
        }

        private void DgvColumnHeaderMerge_Load(object sender, EventArgs e)
        {
            DgvColumnHeaderMerge d_obj = new DgvColumnHeaderMerge();

            this.dataGridView2.Columns.Add("dept_name", "Name");

            this.dataGridView2.Columns.Add("dept_code", "Code");

            this.dataGridView2.Columns.Add("emp_name", "Name");

            this.dataGridView2.Columns.Add("emp_place", "Place");

            this.dataGridView2.Columns.Add("emp_phone", "Phone No");

            // RowCreated(dataGridView2,e);

            //dataGridView2.Rows.Add();


        }

        void dataGridView2_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                //Build custom header.
                GridView oGridView = (GridView)sender;

                //DataGridView oGridView = (DataGridView)sender;
                GridViewRow oGridViewRow = 
                            new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
                TableCell oTableCell = new TableCell();

                //Add Department
                oTableCell.Text = "Department";
                oTableCell.ColumnSpan = 2;
                oGridViewRow.Cells.Add(oTableCell);

                //Add Employee
                oTableCell = new TableCell();
                oTableCell.Text = "Employee";
                oTableCell.ColumnSpan = 3;
                oGridViewRow.Cells.Add(oTableCell);
                oGridView.Controls[0].Controls.AddAt(0, oGridViewRow);
            }
        } 
    }
}


I want the output as following,
---------------------------------------------------------------
Department |       Employee           |
---------------------------------------------------------------
Name | Code | Name | Place | Phone No |
---------------------------------------------------------------
     |      |      |       |          |
---------------------------------------------------------------
     |      |      |       |          |
---------------------------------------------------------------



Kindly help me correct my mistakes.

Thanks and Regards,

Hey Kavya

I'm pretty sure the above code doesn't compile...

An event should be declared as type of delegate, the delegate then dictates what kind of parameters should by supplied when triggering the event and also which parameters are sent to the event handler.

Getting used to how events work is a bit tricky at first. I wrote an article on delegates and events Here[^] that explains it.

Hope this helps
