Hi,
Can you please help me to solve out this
i have a datagridview in Form1 with columns Sl.No , Book no,Book name ,issue date, due date.
when i Enter a book no in Book No column, then all the details of the books
are populated in other columns of datagridview and a new row is added automatically (Datagridview changes to edit mode)where i can enter other book no in book no column of that row to get its details displayed and so on .
For this to happen i am writing my code in Cell Value changed event of datagridview
My code is
private void dataGridViewEx1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 1)
{
if (dataGridViewEx1.Rows[e.RowIndex].Cells[1].Value != null)
{
con = db.open();
BookNumber = dataGridViewEx1.CurrentRow.Cells[1].Value.ToString();
SqlDataAdapter adp = new SqlDataAdapter("SELECT E_NAME FROM BOOKS WHERE BOOK_NO='" + BookNumber.ToString() + "' ", con);
DataSet ds = new DataSet();
adp.Fill(ds, "s");
if (ds.Tables["s"].Rows.Count >= 1)
{
dataGridViewEx1.CurrentRow.Cells[2].Value = ds.Tables["s"].Rows[0].ItemArray[0];
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
dataGridViewEx1.CurrentRow.Cells[3].Value = DateTime.Now;
dataGridViewEx1.CurrentRow.Cells[4].Value = DateTime.Now.AddDays(holddays);
}
else
{
MessageBox.Show("No Such Book Exists.Please check the Book Number", "easyLib", MessageBoxButtons.OK);
SendKeys.Send("{left}");
}
db.close();
}
}
}
This is working fine.
Now consider a situation where i do not know the book No to enter.In such a situation i have written code to display all thebook No ,Book Name details in a datagridview
in other form(Say FORM2). when i press F1 key in Book No column in Form1
form2 is displayed. i select the required book no from Form2 and when i press enter that book no should be displayed in my Form1 book no column.I was able to do that.For that My code in Form1 is
internal void PopulateDGVEX1Row(string prodCode )
{
con = db.open();
dataGridViewEx1.CurrentRow.Cells[1].Value = prodCode.ToString();
SqlDataAdapter adp = new SqlDataAdapter("SELECT E_NAME FROM BOOKS WHERE BOOK_NO='" + prodCode.ToString() + "' ", con);
DataSet ds = new DataSet();
adp.Fill(ds, "s");
if (ds.Tables["s"].Rows.Count >= 1)
{
// dataGridViewEx1.CurrentRow.Cells[1].Value = ds.Tables["s"].Rows[0].ItemArray[0];
dataGridViewEx1.CurrentRow.Cells[2].Value = ds.Tables["s"].Rows[0].ItemArray[0];
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
dataGridViewEx1.CurrentRow.Cells[3].Value = DateTime.Now;
dataGridViewEx1.CurrentRow.Cells[4].Value = DateTime.Now.AddDays(holddays);
}
else
{
MessageBox.Show("No Such Book Exists.Please check the Book Number", "easyLib", MessageBoxButtons.OK);
SendKeys.Send("{left}");
}
dataGridViewEx1.RefreshEdit();
db.close();
}
and in Form2 my code is
private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.F1)
{
prodCode = dataGridView1.CurrentRow.Cells[0].Value.ToString();
f1.PopulateDGVEX1Row(prodCode);
this.Dispose();
this.Close();
}
}
I am getting the Book No in Form1 and its details in other Columns.But My problem is in this case a new row is not added in Form1 when i am getting book no from Form2 unless i enter any value in a datagridview cell in form1.(When i enter a Book No in Column1 a new row is added and i was able to add another book no).How can i make it add a new row automatically to datagridview in Form1when i get book no from other form(Form2).ie i should be able to work in both ways.If i know the book no it's ok but for those which i do not know i should fetch it from other form and should get a new row added in case if there is more book details to be entered
How can i do this .
Thanks in advance
