Asp.Net (Populating DropDownList – The key aspect that needs to be noted)

Posted by paragdongre on November 6, 2007


Some times you may notice that, you are getting the following values in your dropdownlists.

<option value=”System.Data.DataRowView”>System.Data.DataRowView</option>

When binding to the DropDownList (and some of the other controls), you need to specify the DataTextField and DataValueField (if you don’t specify the DataValueField then the control will automagically use what you specified for the DataTextField).

Something like this….

DropDownList1.DataTextField = “FieldNameThatIsToBeDisplayedForEachItem”
DropDownList1.DataValueField = “FieldNameThatRepresentsTheValueOfTheItem”
