I guess what you need is to Set minValue = 20 and maxValue = 100

Hi,    i don't think u can have min value & max value for a combo box Satish Pai B

Hi,    we can set a datatable to datasource.if u want to fill those numbers to combobox we need to loop & then fill datatable & then assign it to combobox.datasource property. Better to use "combobox1.items.add " & a loop . Display member property is used when we have more no.of columns in a query for ex: -    <b>         SqlCommand cmm = new SqlCommand();                   cmm.CommandText = "select Emp_Id,Emp_Name,Emp_Address from Employee";                   cmm.CommandType = CommandType.Text;                   cn.open();                   cmm.Connection = cn;                   DataTable dt = new DataTable();                   SqlDataAdapter sqldt = new SqlDataAdapter(cmm);                   sqldt.Fill(dt);                   comboBox1.DataSource = dt;                   comboBox1.DisplayMember = "Emp_Name";                   comboBox1.ValueMember = "Emp_Id";                   cn.close();</b> While Displaying it Displays employees Name & if u are going to save it in table then we can use "comboBox1.selectedvalue" property were we get the Emp_Id

i don understand what u mean "min value & max value" ? however i think that in my combo box just store some string values n id. and i want to ask u a bit more... does combo box can store more then 2 colume or fields. for eg: Emp_ID, Emp_Name, Emp_Gender,Emp_Phone.. ?

No Combo Box can store only 2 columns by 2 Properties 1.DisplayMember - This does the work a displaying a column 2.ValueMember - This does a work what value should be returned when a particular item is choose d. Ex:- EmpID EMP_Name 1 abc 2 def 3 xyz when u select a Emp_name - "def" from combo box & if u use "combobox1.selectedvalue" then it returns 2 or if u select "xyz " then it returns 3 doesn't mind if u still didn't get it.Just reply for doubts.
