IF I DO LIKE THAT , I am getting runtime exception client_id doesn't have a default value.
because in my datagrid control I am only displaying two values and i'm taking client_id value from combobox

Well, you should have then explained better what you want to achieve. You can try inserting recors manually, something like this:
MySqlCommand cmd = new MySqlCommand ("INSERT INTO MyTable (field, field2, field3) VALUES (" + value1 + ", " + value2 + ", " + value3 + ")", myConnection);
myConnection.Open();
cmd.ExecuteNonQuery();
myConnection.Close();
the above example assumes all the fields are of numeric type, if you have string column, then you would need to put value between ' '.
MySqlCommand cmd = new MySqlCommand ("INSERT INTO MyTable (field, field2, field3) VALUES (" + value1 + ", " + value2 + ", " + value3 + ")", myConnection);
myConnection.Open();
cmd.ExecuteNonQuery();
myConnection.Close();

CAN YOU HELP ME ,HO TO ACCESS THE CURRENT COLUM VALUE FROM DATAGRID CONTROL
No need for capital letters. :) There is a difference between datagridview and datagrid control, I gues you are talking about datagridview control, based on the title of the topic
// if you want to get string value of the first cell in first row
string temp = datagridview1[0, 0].Value.ToString();
// if you want to get integer value of the 2nd cell in fourth row
int temp = Convert.ToInt32(datagridvi ew1[2, 4].Value);
// if you want to get string value of the first cell in first row
string temp = datagridview1[0, 0].Value.ToString();
// if you want to get integer value of the 2nd cell in fourth row
int temp = Convert.ToInt32(datagridvi
Ah, forgot to add how to get the current cell value
dg.CurrentCell.Value
if you want to know what is the column/row index of the currently selected cell
dg.CurrentCell.ColumnIndex
dg.CurrentCell.RowIndex
dg.CurrentCell.Value
if you want to know what is the column/row index of the currently selected cell
dg.CurrentCell.ColumnIndex
dg.CurrentCell.RowIndex

Thanks Priest04,
I have placed datagridview control on the form.
What i want to do is, when the user clicks add button,the datagridview control should insert an extra row and the cursor should be focused on that row,so that user can enter the row
currently the datagridviewcontrol is showing 1 extra empty row,which i dont want to show
can you tell me how can i achieve this

Thankyou
1) you use DataAdapter to fill data to datatable
- create new datadapter, using theSELECT statemtent above mentioned-
MySqlDataAdapter da = new MySqlDataAdapter(SQLSelect
- create new datatable
DataTable dt = new DataTable();
- use dataadapters Fill method to fill data to datatable
da.Fill(dt);
2) bind datagridview to this datatable
datahridview1.DataSource = dt;
3) after you have done editing datagridview, use dataadapters Update method to update data from tatatable to database
da.Update(dt);
