Question

I Want To bind my dropdownlist with two value using some separator just [like ‘-‘ or ‘/’] in .net 3.5.

 qry = "SELECT CityName, MasterState.StateName FROM MasterCity INNER JOIN "+
              "MasterState ON MasterCity.StateID = MasterState.StateID order by CityName";

DropCity.DataMember = "DeafultView";
//DropCity.DataTextField = "CityName";
//DropCity.DataValueField = "CityName";
DropCity.DataTextFormatString = "{0} - {1}";
DropCity.DataTextField = "CityName,StateName";
DropCity.DataSource = dt;
DropCity.DataBind();
DropCity.Items.Insert(0, "-Select-");**

I did it but it gives error

DataBinding: ‘System.Data.DataRowView’ does not contain a property with the name ‘CityName,StateName’.”}

How can i do this?

Answer 1

DropCity.DataTextField = "CityName,StateName";

DataTextField will look for column CityName,StateName and it doesn’t exist.

May be you can change your query like this

qry = "SELECT CityName, CityName + '-' + MasterState.StateName as CityState
    FROM MasterCity INNER JOIN "+
          "MasterState ON MasterCity.StateID = MasterState.StateID order by CityName";

    DropCity.DataTextField = "CityState";
