Question

I am new to asp.net and want to know that does setting DataKeyNames property make sense when dynamically binding data? I have bind data using following code

gvCategory.DataSource = objCategoryInfo;
gvCategory.DataBind();

here gvCategory is my gridview that I created at designview and objCategoryInfo is my datasource. Is it necessay to set DataKeyNames property at design time.?

Thanks in advance.

Only if you want the automatic update or delete feature to work with GridView

GridView.DataKeyNames Property – MSDN

Use the DataKeyNames property to specify the field or fields that
represent the primary key of the data source. You must set the
DataKeyNames property in order for the automatic update and delete
features of the GridView control to work.
