William Becknell, a Missouri merchant, took the first wagon train, of three wagons, to Santa Fe (in present-day New Mexico), from May to July 1822; and the first wagon trail from Santa Fe to southern California seems to have been marked during the Mexican-American War by Lt.

It will display in the GridView control. To do that we create a connection string object to connect the database with the application and read data from the database using the select command to display data in the DropDownList.
Then the user can type a value in the text box, or select one from the list. The user can type any text in the text box, even if it does not appear in the list. If you set the DropDownStyle to DropDown, the ComboBox will display a text box and a drop-down list. Then the user can type a value in the text box or click the drop-down arrow to the right of the text box (the control displays the list where the user can select an item).
