DatagridView as View-detail

If we want to save data from WinForm; we just design our form, drag some labels & text-boxes on it and finally part of coding....
We have to code for Insert Data / Update Data / Delete Data...
for each work we design or code a individual part of coding...

But, here is the simplest way to do all that work without any coding and on a one single WinForm page...

Let's see :

1) Open  your WinForm project & add new winform on it.
2) Go to Data --> Click on Show Data Source

[it will show DataSource window just left side of screen]

3) Click on 'Add New Data Source' 

4 ) Data Configuration window will be appeared.
     Select 'Database' & click 'Next'
     Select 'Dataset' click 'Next'
     Your connection string may selected on ConnectionString ; if not click on 'New Connection' and select which database you want to select
     Click 'Next'
5) Select which table you want to choose & enter unique and meaningful DataSet Name and Click 'Finish'

6)  Select dataSet name which we recently added ...

7) After selected 'Details' view select  Just 'Drag & Drop' Profile detail view on form .. it will see like below

8) that's it...

    You can now 'Add/Delete/Update' data from just one single Winform page without doing any coding...

   You can also see all your records from navigator buttons.

Thnak you.

Working with Crystal Report with c#

Monthly rpt = new Monthly();

            using (SqlConnection con = new SqlConnection(CS))

            {

                con.Open();

                SqlCommand cmd = new SqlCommand("spReport", con);

                cmd.CommandType = CommandType.StoredProcedure;

                cmd.ExecuteNonQuery();

                SqlDataAdapter da = new SqlDataAdapter(cmd);

                DataSet dsTemp = new DataSet();

                da.Fill(dsTemp, "tb_DentcoLab");

                DataTable dt = new DataTable();

                da.Fill(dt);

                dt = dsTemp.Tables["tb_DentcoLab"];

                

                 if (dt.Rows.Count > 0)

                {

                    ReportDocument repDoc = new ReportDocument();

// To show any value from Form1.cs to CrystalReport 

                    TextObject txtDateToFrom = (TextObject)rpt.ReportDefinition.ReportObjects["txtDateToFrom"];

                    txtDateToFrom.Text = "" + DateTime.Now.ToString("dd MMM yyyy") + "";

                    TextObject txtDocName = (TextObject)rpt.ReportDefinition.ReportObjects["txtDocName"];

                    txtDocName.Text = "" + txtDoctorName.Text + "";

                    TextObject txtAddress = (TextObject)rpt.ReportDefinition.ReportObjects["txtAddress"];

                    txtAddress.Text = "" + _DocAddress + "";

                    TextObject txtInvoiceNo = (TextObject)rpt.ReportDefinition.ReportObjects["txtInvoiceNo"];

                    txtInvoiceNo.Text = "" + txtInvoice.Text + "";

                    

                    rpt.SetDataSource(dsTemp);

                    RV.ReportSource = rpt;

                    RV.Zoom(1);

                }

                else

                {

                    MessageBox.Show("No Data found");

                }
