show data in comboBox

Get Data from database then assign to Combobox as below.

Dropdownlist1.DataSource = dtTemp; //Sample Datatable which contains data
Dropdownlist1.DataBind();
Dropdownlist1.DataTextField = "EmployeeName";
Dropdownlist1.DataValueField = "EmployeeID";

Mate, you must need C# Book for your basic knowledge in that. Happy coding.

'select idfield as ID, namefield as Name from table
fill t result of query to a dataset after that

combobox. datasource =dataset.tables(0)
cmbDrCr.DisplayMember="ID"
cmbDrCr.ValueMember="Name"

First assign data from database to a dataset or a datatable
Then bind ComboBox using the data

comboBox1.DataSource = dataSet1.Tables["TableName"];
comboBox1.DisplayMember = "Column Name";

Dear friend,
First of all if u are beginner in C#.Please download Murach C# 2008 by wrox publication.That may be best for beginner to learn C#.

let go to the point
if your combo box name cmbEmployee
then
declaire DataTable
DataTable dt=new DataTable();
Here for dt=Query required from database
cmbEmployee.datasource=dt;
if it is Desktop Application then
cmbEmployee.DisplayMember="Column Name";
if it is asp then

cmbEmployee= "EmployeeName";
cmbEmployee.DataValueField = "EmployeeID";
cmbEmployee.DataBind();
