databinding on a datagrid

[dhol]

Hi I was about to design a form witha datgrid and some buttons with certain operations namely first, previous ,next and last and some text boxes I have to read two xml file( each xml file has one table)with data in it. Now I have to create a relation between the two tables and display it in the datagrid. Now using databinding I have to show the data from the datagrid columns to each text box when teh next, previous ...etc buttons r clicked. that is values from one column for ex: column name :DESC values :MR BROS, VT BROS, CT BROS when next is clicked, the values should be shown from the desc in to the textbox one by one. This i have did it this is the folowing code private DataSet ds = new DataSeyt(); retrieve button click private void RetrieveButton_Click_1(object sender, System.EventArgs e) { DataSet xml1 = new DataSet(); xml1.ReadXml("C:\\CDEV\\Relation\\cost_code.xml"); DataTable dt1 = xml1.Tables["cost_code"].Copy(); DataSet xml2 = new DataSet(); xml2.ReadXml("C:\\CDEV\\Relation\\cost_type.xml"); DataTable dt2 = xml2.Tables["cost_type1"].Copy(); ds.Tables.Add(dt1); ds.Tables.Add(dt2); DataColumn parentCol = ds.Tables["cost_type1"].Columns["cost_type"]; DataColumn childCol = ds.Tables["cost_code"].Columns["cost_type"]; DataRelation relTable1Table2; relTable1Table2 = new DataRelation("cost_typecost_code", parentCol, childCol); ds.Relations.Add(relTable1Table2); this.dataGrid1.DataSource = ds.Tables["cost_type1"]; fnDataBindingforTextBoxes(); fnSetCurrencyManager(); } private void fnDataBindingforTextBoxes() { this.ultraCostPaid.DataBindings.Add("Text", ds.Tables["cost_code"],"desscost_paid_by_us"); this.ultraCostType.DataBindings.Add("Text", ds.Tables["cost_code"],"cost_type"); } private void fnSetCurrencyManager() { currManager=(CurrencyManager)this.BindingContext[ds.Tables["cost_code"]]; } everything is working fine but databinding on the grid is not used. that is if u select a row from the datagrid it should change the values in the textbox that i have already added data bindings for. if u notice just selct a row from the grid, now the values in that row should show in your textboxes you have put below. Give a dataview for dataset pls help me to do this j o hn
