No, you have store data to store and retrive from it. You can use CSV, XML and Registry and Also Database to store data .:-D and you have to use any one of them to permanently store data!!!:-D

Thanks for Explining, I am asuming your database has Roll, Name , Address , Marks fields And Create a Load_Grid() Function on form_load() Load_Grid() { Load data to grid(); } Now see, in your datagrid there may be multiple records ? is it ? Now read the key value from that row, and pass the value in the next form. Supoose u select row 2 and roll=5, pass this to form 2, u can easily access the controls of other form just creating the object and access. Now in Form2, There is Three Text box, Roll : txtroll Name: txtName Address : txtAddress Now, SQLCommand cmd=new sqlcommand("select * from student where roll='_RollVal',conn) // _RollVal is passed value SqlDataReader dr=new Sqldatareader(); dr= cmm.executenonquery(); now u can get the value txtRoll.Text=dr[0].text txtName.Text=dr[0].text Now change the vale in text box, and on click on UpdateButton .... Update database [ Just use Update Command to Update] and back to the Form1..... , and all refresh data will come to you grid, cause , load_grid() will call on Form Load.:cool::cool: Hope You like This..... And for any query ask me ;) Good luck :)

But, unless you use a database u can't store data permanently. At least you have to use a XML or CSV file do store records.;)

Why u make that simple thing as complex, if you dont want to use database just use XML 1 Abhijit Microsoft Use XMLReader and Write Object to Read and Write. It's Very Simple, :laugh: U can Create and Delete The XML File RunTime Also... So, No Overhead !!!
