Maybe this one: Tuples are supported in .NET 4.0 // member of class private List > types; private void constructorOrLoadPage() { types = new List >(); // init your cases types.Add(Tuple.Create(city City Details cityid City ID cityname City Select * from city_master)); types.Add(Tuple.Create(state State Details stateid State ID statename State select * from state_master)); types.Add(Tuple.Create(country Country Details countryid Country ID countryname Country select * from country_master)); types.Add(Tuple.Create(category Category Details categoryid Category ID categoryname Category select * from category_master)); types.Add(Tuple.Create(designation Desination Details designationid Designation ID designation Designation select * from designation_master)); } public void CheckMethod(string menuType) { foreach(Tuple type in types){ if (type.Item1 == menuType) { lbltitle.Text = type.Item2; BoundField field = new BoundField(); field.HeaderText = type.Item4; field.DataField = type.Item3; DataControlField col = field; GVDetails.Columns.Add(col); field = new BoundField(); field.DataField = type.Item6; field.HeaderText = type.Item5; col = field; GVDetails.Columns.Add(col); DataSet ds4 = obj.LoadDataSet(type.Item7); GVDetails.DataSource = ds4.Tables[0]; GVDetails.DataBind(); return; } } }

Here is the source code of method which solves your problem: private void BindField(string title string dataField headerText string loadQuery) { if (!string.IsNullOrEmpty(title)) lbltitle.Text = title; BoundField field = new BoundField(); field.DataField = dataField; field.HeaderText = headerText; DataControlField col = field; GVDetails.Columns.Add(col); if (!string.IsNullOrEmpty(loadQuery)) { DataSet ds1 = obj.LoadDataSet(loadQuery); GVDetails.DataSource = ds1.Tables[0]; GVDetails.DataBind(); } } In that case main code (function mostly in red) looks like this: protected void Page_Load(object sender EventArgs e) { menuType = Request.QueryString[type]; if (!Page.IsPostBack) { switch (menyType) { case city: BindField(City Details cityid City ID null); BindField(null cityname City Select * from city_master); break; case state: BindField(State Details stateid State ID null); BindField(null statename State Select * from state_master); break; case country: BindField(Country Details countryid Country ID null); BindField(null countryname Country Select * from country_master); break; case category: BindField(Category Details categoryid Category ID null); BindField(null categoryname Category Select * from category_master); break; case designation: BindField(Designation Details designationid Designation ID null); BindField(null designation Designation Select * from designation_master); break; } } } Don't mind the switch statement receiving strings. Many people fear it's not efficient but it is because strings in the case clauses are pre-compiled and stored in the memory section containing constant strings so comparing against them goes much quicker than multiple if-else if statements.
