@JackDingler
I have a small theory can you verify my concept -
Accessibility of a class's constructors and destructor only affects the creation or destruction of object of that class. You will need at least one of the publicly accessable constructors or destructor for creating or destructing object of a class.

@Richard MacCutchan Thank you for your link
But I need a glass of water and you thrown me in Swimming Pool.

Please give me some easy explanation as I am in learning phase not an expert like you.

Thank You Lukker You are right
I was confuesd with the loops

You can see the table in my post where I have made everything clear
Take Example No. 1. ROW1 and ROW4 is having same values that is 2 2 2 again ROW1 and ROW2 have same value 6 and again ROW1 and ROW2 and ROW4 have same value 7 7 7 so now I want to color them with RED color as showing the conflicts.
Take Example No. 2. ROW2 and ROW3 have same value 1 1 so I want to color them in RED to show the conflict.
I hope now my intention is clear

Thank You Kumar but I want to view this table with full data I don't want to use DISTINCT.
Here is the C# code of winform
public void check_conflict()
{
int rowCount=dataGridView1.RowCount;
int colCount=dataGridView1.ColumnCount;
string val1;
int c = 1;
for (int k = 0; k < rowCount - 1; k++)
{
for (int i = 1; i < colCount; i++, c++)
{
val1 = Convert.ToString(dataGridView1.Rows[k].Cells[i].Value);
for (int j = 1; j < rowCount - 1; j++)
{
string val2 = Convert.ToString(dataGridView1.Rows[j].Cells[i].Value);
if (val1 == val2 && (val1 != "" && val2 != ""))
{
DataGridViewCellStyle CellStyle = new DataGridViewCellStyle();
CellStyle.BackColor = Color.Red;
dataGridView1.Rows[j].Cells[i].Style = CellStyle;
}
}
}
}
Problem I facing with code is it is only comparing 1 Row with others

I want to show checkbox under each day(columns) and values from database in these checkbox.

Yes I do understand the purpose of checkbox whether the option is selected or not. So if I want to select Sun day then I I want to put a tick on checkbox means Select Sunday and if it is not tiked means I don't want Sunday. And the value of check box will be saved in Access database as Yes/No. Well what best way you have please let me n

Thanx u r right...

Thank you for suggestion but can you please give some small hint on code how to use same event handler for all of the comboboxes

Thank you for your guidance.. But I am bit confused about your code. What does myComboBox represent in your code. If it the name of one of the combo box out of 84 combo boxes then how the problem is solved?

I mean to say that if I need to fix timing for days say take an example - under group1 I have selected 3 days - Sun, Mon and Thr and from Group 2 I have selected 5 days-Mon, Tue,Wed, Thr,Fri.
Now I have to fix timing and teachers for all days in next step. So How can I adjust A teacher for Group1 Sun period 1, B teacher Sun period 2, C teacher Sun period 3, B Teacher Mon Period 1, A teacher Mon Period 2, A teacher Mon Period 3 and so on. Now you can understand Why I need to club Group and their Days respectively.

@Ankit If I pass 2 List how can I relate groupbox with checkbox any hint

How can pass the values of checkboxes with their respective groupbox via constructor. I am actually confused about this only

Please see this code for clarification
<pre lang="c#">
GroupBox[] grpBox;
CheckBox[] dayCheckBox;
int grpposition = 40;
public step2(List<string> list)
{
InitializeComponent();
int x = list.Count;
grpBox = new GroupBox[x];

for (int i = 0; i < x; i++)
{
grpBox[i] = new GroupBox();
grpBox[i] = new GroupBox();
grpBox[i].Name = "gpBox" + Convert.ToString(i);
grpBox[i].Text = list[i];
grpBox[i].Location = new Point(5, grpposition);
grpBox[i].Width = 500;
grpBox[i].Height = 75;
this.Controls.Add(grpBox[i]);

dayCheckBox = new CheckBox[7];
String[] dayName={"Sun","Mon","Tue","Wed","Thr","Fri","Sat"};
for (int j = 0; j < 7; ++j)
{
dayCheckBox[j] = new CheckBox();
dayCheckBox[j].Name = "radio" + Convert.ToString(j);
dayCheckBox[j].Text = dayName[j];
dayCheckBox[j].Width = 50;
dayCheckBox[j].Location = new System.Drawing.Point(70 * j, 25);
grpBox[i].Controls.Add(dayCheckBox[j]);
//dayCheckBox[i].CheckStateChanged += new System.EventHandler(dayCheckBoxCheckedChanged);
}
grpposition += 80;
}</pre>

1st option is looks Good. As I already done same thing for Step1 to Step2. I used List<string> in Step1 to pass the groupBox names to the constructor of Step2 Form. And from Step2 I need both the groupbox and checkbox names respectively. And Yes Section(Groupbox) can increase.
By this way
<pre lang="c#"> list = new List<string>();
}

private void BatchBoxCheckedChanged(object sender, EventArgs e)
{
CheckBox batchBox = (CheckBox)sender;
//Here I want to store name of checkbox in array

if (batchBox.Checked == true)
{
list.Add(batchBox.Text);
}
}
private void button1_Click(object sender, EventArgs e)
{
step2 st2 = new step2(list);
st2.ShowDialog();
} </pre>

Hi Maciej
I never used list but I think it I have to do something like this
<pre lang="c#">List<checkbox> chks = Controls.OfType<checkbox>().ToList();</pre>
But after this how can I get the name of batchBox (dynamic checkbox) name and store them in list. Can you give some code snippet

Thank you Maciej Los
I gave a deep thought as you suggested and found the way

Sorry for confusion I actually mean by this "I want to add record of access database in datagridview when button is clicked" is " I want to show record of database in datagridview" I am able to view all records at once on button click. But this is not my purpose... Can you give some more lights on the idea

Thank you for suggestion but... I don't want to insert record in database, I want to show record of database, as 1 record on 1 button click in datagridview

I already done with these articles and also if you gone through my issue then you can see I am able to created dynamic check box done many operation with them. I want to generate dynamic groupbox based on checkbox selection

Yes but confused what to do to get the name or reference of selected checkboxes
