should not able to bind list in asp.net

Question

public static List<TemplateInfo> GetTemplateList()
    {
        DirectoryInfo dir = new DirectoryInfo("E://DotNetProjects//sftemplating//Templates");
        List<TemplateInfo> lstTemplates = new List<TemplateInfo>();
        foreach (DirectoryInfo temp in dir.GetDirectories())
        {
            TemplateInfo tempObj = new TemplateInfo(temp.Name);
            lstTemplates.Add(tempObj);
        }
        return lstTemplates;
     }

and

public void BindTemplate()
    {
        ddlTemplateList.DataSource = GetTemplateList();
        ddlTemplateList.DataBind();
    }

info is

public class TemplateInfo
    {
        public string TemplateName { get; set; }


        public TemplateInfo() { }        

        public TemplateInfo(string TemplateName)
        {
            this.TemplateName = TemplateName;

        }
    }

and i call BindTemplate in pageload like this

if (!IsPostBack)
        {
            BindTemplate();
        }

but ddlTemplateList is bind with Templating.TemplateInfo.Templating is my namespace.Whats my problem.Plz help to find my mistake.

are you getting error? can you check in debug weather GetTemplateList returns list what you wanted? — Pragnesh Patel

i think you have to set DataValueField & DataTextField for your dropdown list. ddlTemplateList. ddlTemplateList.DataTextField ="TemplateName"; ddlTemplateList.DataValueField = "TemplateName"; — Pragnesh Patel

I think you miss to assgin thie

 ddlTemplateList.DataTextField="texttodisplay" ;
 ddlTemplateList.DataValueField="value";

You your code will be

public void BindTemplate()
{
    ddlTemplateList.DataSource = GetTemplateList();
    ddlTemplateList.DataTextField="texttodisplay" ;
    ddlTemplateList.DataValueField="value";
    ddlTemplateList.DataBind();
}
