hi i have already connected the database in Ms-access 2010(.mdb) with C# then i want to display it in datagrid view , here is the code that i used to save or insert the data

OleDbCommand cmd = new OleDbCommand();
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = "insert into VMS(PlateNo,JobCardNo,Model,DateIn,Status,PartList,PurchNo,PurchDate,Remark)" + "values('" + textBox1.Text + "','" + textBox2.Text + "','" + textBox3.Text + "','" + textBox4.Text + "','" + textBox5.Text + "','" + textBox6.Text + "','" + textBox7.Text + "','" + textBox8.Text + "','" + textBox9.Text + "')";

This is the best way To update your datagridview after inserting some data.

Dataset sDs = new DataSet();

sAdapter.Fill(sDs, "T1");

sTable = sDs.Tables["T1"];

dataGridView1.DataSource = sDs.Tables["T1"];

To update your datagridview after inserting some data , you should rebind your data grid view , some sudocode might be like this :

OledbConnection conn=new OledbConnection("your connectionstring");
OledbCommand comm=new OledbCommand("SELECT * FROM yourtablename",conn);
OledbDataAdapter da=new OledbDataAdatpter(comm);
Dataset ds=new dataSet();
conn.open();
da.Fill(ds,"T1");
datagridView.DataMember="T1";
datagridview.DataSource=ds;
conn.close();

NOTE: if your project is an asp.net project after assigning the datasource you have to write the method DataBind() to your datagridview this way :

datagridview.DataSource=ds;
datagridview.DataBind();

but in windows applications you don't have to perform the method DataBind()

please mark as answer if you It solved your problem
