I want to sort data in combox
data in combox is fetched from column in datatable

I used the following code for fetch data to combox

C#

comboBox1.DataSource = WorkersMgr.GetALLWorkers();
            comboBox1.DisplayMember = "Full_Name";
            comboBox1.ValueMember = "Worker_ID";

note : GetAllWorkers() returns all workers from workers table

what was the code written in GetAllWorkers(), you need to modify that code to sort your data while selecting it from database.

like if you are directly fire select query like this

SQL

SELECT FULL_NAME,WORKER_ID FROM WORKSRS

then you need to change your code like this

SQL

SELECT FULL_NAME,WORKER_ID FROM WORKRS ORDER BY FULL_NAME ASC  -- if you need to sort data A to Z

OR

SELECT FULL_NAME,WORKER_ID FROM WORKRS ORDER BY FULL_NAME DESC  -- if you need to sort data Z to A

like this you can sort your data first then you need to bind it to your combobox, you need to write your own query based on your database structure.

The easiest way it to use a DataView, instead of the DataTable directly:

C#

DataTable dt = new DataTable();
dt.Columns.Add("MyColumn");
dt.Rows.Add("123456");
dt.Rows.Add("923456");
dt.Rows.Add("523456");
dt.Rows.Add("223456");
dt.Rows.Add("023456");
comboBox1.DataSource = dt;
comboBox1.DisplayMember = "MyColumn";
DataView dv = new DataView(dt);
dv.Sort = "MyColumn";
comboBox2.DataSource = dv;
comboBox2.DisplayMember = "MyColumn";

Sets up two combos from the same data, and sorts one of them.
