  • for that first create aconnection with the database. Then create one Adapter and fire a querry in your adpter and fill the dataset with adapter and give your gridview datasource that dataset. e.g. [CODE] OleDbConnection con=new OleDbConnection ("Connection String"); Con.OPen(); string str="Select [name] from [tabel] Where [name] like '%" + … Read More

for that first create aconnection with the database. Then create one Adapter and fire a querry in your adpter and fill the dataset with adapter and give your gridview datasource that dataset.
e.g.

OleDbConnection con=new OleDbConnection ("Connection String");
Con.OPen();
string str="Select [name] from [tabel] Where [name] like '%" + textbox1.Text + "%'";
OleDbDataAdapter da=new OleDbDataAdapter (str,con);
Dataset ds=new Dataset();
da.Fill(ds,"table");
mygrid.DataSource=ds;
''mygrid.DataMember="table" ''sorry i'm not sure about this property
''but other then all the code is right
con.close();

try it.

You should add ds.Clear() to overwrite the records every time you click search.

Line 27:         OleDbDataAdapter da=new OleDbDataAdapter (str,con);
Line 28:         Dataset ds = new Dataset();
Line 29:         ds.Clear();
Line 30:         da.Fill(ds,"tableRegister");

i got error there..it state..
CS0246: The type or namespace name 'Dataset' could not be found (are you missing a using directive or an assembly reference?)

at th general decalration define the
OleDbConnection con=new OleDbConnection();
OleDbDataAdapter da=new OleDbDataAdapter ();
DataSetc ds=new Dataset();
i think you did'nt add the namspace of Syste.Data Or System.Data.OleDb

OleDbConnection con = new OleDbConnection();
        con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\priteshv\\My Documents\\db1.mdb;Persist Security Info=False";
        con.Open();
        string str = "Select * from [Name] Where [name] like '%" + TextBox1.Text + "%'";
        ////AccessDataSource1.SelectCommand = str;
        OleDbDataAdapter da = new OleDbDataAdapter(str, con);
        DataSet ds = new DataSet();
        ds.Clear();
        da.Fill(ds, "Name");
        GridView1.DataSource = ds;
        GridView1.DataMember = "Name";
        GridView1.DataBind();
        con.Close();

see this i had created and which is work very good.

        string str = "SELECT * FROM tableRegister WHERE StaffName LIKE '%" + TextBox1.Text + "%'";

        OleDbConnection con = new OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path);
        con.Open();
        
        OleDbDataAdapter da=new OleDbDataAdapter (str,con);
        DataSet ds = new DataSet();
        ds.Clear();
        da.Fill(ds,"tableRegister");
        GridView1.DataSource = ds;
        GridView1.DataMember = "tableRegister";
        GridView1.DataBind();

        con.Close();
