Use DataTable in DataSourcs

[Robert]

I try add sourse to DropDownList, but this dosn't return result...
Object r is List<CultureInfo>
           

DataTable dtLangs = new DataTable();
dtLangs.Columns.AddRange(new DataColumn[] {new DataColumn("ID"), new DataColumn("Name")} );
AppSetting.Instance.Languages.Select( r => dtLangs.Rows.Add(r.TwoLetterISOLanguageName, r.DisplayName));

this.ddlLanguage.DataSource = dtLangs;
this.ddlLanguage.DisplayMember = "Name";
this.ddlLanguage.ValueMember = "ID";

Hi Robert,

Your lambda expression does not add any rows to the DataTable. I have added the rows manually and the RadDropDownList is successfully displaying the languages. Using your code I have created and attached sample project. In the sample I am manually populating your data table with all the languages that current machine have.

I hope this helps. Should you have any other questions do not hesitate to ask.
