Binding a Dictionary to a Drop Down List

Binding data from a Dictionary is not so challenging as “Key” and “Value” pairs can be used for the drop down list properties. Following code samples show the results after assigning data source to the drop down list.

Before

Dictionary genderDictionary = new Dictionary();
genderDictionary.Add(1, "Male");
genderDictionary.Add(2, "Female");
genderDictionary.Add(3, "Transgender");

this.ddlGender.DataSource = genderDictionary;
this.ddlGender.DataBind();

Before Assign Key Value Pair





After

this.ddlGender.DataSource = genderDictionary;
this.ddlGender.DataTextField = "Value";
this.ddlGender.DataValueField = "Key";
this.ddlGender.DataBind();

After Assign Key Value Pair
