Web part custom property - dropdown list

December 19, 2007 09:40 by aidan

It isn't immediately obvious how to include a drop down list as a custom property on a web part. To do this you simply use an enum.

Eg.

//create enum

public enum ProductByEnum

{Type = 0,

Brand,

Chemistry};

//create get/set for the property

protected ProductByEnum productsBy;

[Personalizable(PersonalizationScope.User),WebBrowsable, WebDisplayName("Products By"),WebDescription("Use this property to change web part grouping")]public ProductByEnum ProductsBy

{

get { return productsBy; }

set { productsBy = value; }

}

A dropdown list will now appear in the miscellaneous section of your web part custom properties containing the enum values.

How can do for that ProductByEnum to be variable.

The DropDown generated like that to be dynamic.

Thank... Jorge

Hi Jorge,
I'm not 100% sure what you are asking. Do you want to populate the drop down dynamically from a database table? I have not done this but you could try to do this by populating the values of your enum from the values in the database. Is that what you want to do or are you asking something else entirely?

without using an enum, i need to have a dropdown list in the custom properties wherein it gets values from Custom list.
whenever i add values to the list it needs to be reflected on the properties list pane.
