C# code to bind data in a combo box in Windows Application

Let's say we have a DataTable with the values being filled as under

public DataTable GetData()

{

        DataTable dt = new DataTable();



        //Add some columns

        dt.Columns.Add(new DataColumn("ImageID", typeof(Int32)));

        dt.Columns.Add(new DataColumn("ImageData", typeof(string)));



        //Add some rows



        //First Row

        DataRow row1 = dt.NewRow();

        row1("ImageID") = 1;

        row1("ImageData") = "ImageData1";



        //Second Row

        DataRow row2 = dt.NewRow();

        row2("ImageID") = 11;

        row2("ImageData") = "ImageData11";



        //Third Row

        DataRow row3 = dt.NewRow();

        row3("ImageID") = 12;

        row3("ImageData") = "ImageData12";



        //Fourth Row

        DataRow row4 = dt.NewRow();

        row4("ImageID") = 15;

        row4("ImageData") = "ImageData15";



        //Fifth Row

        DataRow row5 = dt.NewRow();

        row5("ImageID") = 18;

        row5("ImageData") = "ImageData18";



        //Sixth Row

        DataRow row6 = dt.NewRow();

        row6("ImageID") = 19;

        row6("ImageData") = "ImageData19";



        //Seventh Row

        DataRow row7 = dt.NewRow();

        row7("ImageID") = 21;

        row7("ImageData") = "ImageData21";



        //Add the rows to the table

        dt.Rows.Add(row1);

        dt.Rows.Add(row2);

        dt.Rows.Add(row3);

        dt.Rows.Add(row4);

        dt.Rows.Add(row5);

        dt.Rows.Add(row6);

        dt.Rows.Add(row7);



        //return the table

        return dt;

}

Then fill into the combobox as under

DataTable dt = GetData();

comboBox1.Datasource = dt; //set the combobox data source

comboBox1.DisplayMember = ImageID; // Display column

comboBox1.ValueMember = ImageData;  // Value member column
