Programmatically Binding Data. Source To Combo. Box In Multiple Ways.

Sometimes we need to load a list of items to a Combo. Box or Drop. Down. List for the user to select a value to be processed. Items are loaded in the Combo. Box generally to be bound to a data source of the Combo.

Box. A The data source is bound to a Combo. Box using the . As per MSDN documentation, Data. Source can be an object that implements the IList interface (such as a Data. Set, Data. Table, List, Array, and Data. View). The default is null. When the Data. Source property is set, the items collection cannot be modified.

To explain data source binding with various objects I created a demo project that demonstrates the following kind of bindings: Binding Data. Source with Array. Binding Data. Source with List. Binding Data. Source with Data. Set. Binding Data.

Source with Data. Table. Binding Data. Source with Data. View. Binding Data. Source with Enumeration Values. For our understanding a sample project is also attached with this article.

Here is a screen shot of the main form of the project: Binding with Array. We know that any object implementing the IList interface can be bound to a . Array is one of them. Suppose we have a class . Now we want to populate a Combo.

Box with the person's name and when the user selects a name on the list, his/her corresponding gender is displayed. Here is the related codeclass Person . Here we want to display a person's rank in the list and when the user selects a rank from the Combo.

Box items, the corresponding name is displayed. Now let us see how to bind a Data. Set as a Data Source.

Name, First. Name and City. Out of these columns any two columns that can be chosen as Dispaly. Member and as Value. Member respectively while binding with Data. Set. STORED PROCEDURECREATE PROCEDURE .

Data. View is generally used to get a collection in a desired view after filtering out some rows from a Data. Table. In the following code, we got the data from the database in a Data. Table and after that we filtered out some rows ( ID > 5 ) and saved the required filtered data into a Data. View. Actually the Get. Values() method of Enum returns an array of objects (as we know, that implements the IList interface). We can use this method to convert an enum to an array and bind to a Combo.
