c# - Get entity object from CommandArgument in GridView RowCommand -

i using gridview bound list<customer>. when rowcommand fired button want able retrieve current row's customer object e.commandargument, so:

protected void gridview_rowcommand(object sender, gridviewcommandeventargs e) {     customer customer = (customer)e.commandargument;     dosomething(customer); } 

how assign customer object commandargument before event fired?

i not sure can store complex object in commandargument seems take string or numeric values.

something, have never put practice, convert object json string , use command argument.

for example, using newtonsoft.json , dummy object called foobar

<asp:button id="btnone" runat="server"  commandname="click"  commandargument='<%#newtonsoft.json.jsonconvert.serializeobject((foobar)container.dataitem) %>'  text="click" /> 

then when handle gridview rowcommand click event, can deserialize object commandargument

foobar foobar = newtonsoft.json.jsonconvert.deserializeobject<foobar>(e.commandargument.tostring()); 

now works, whether best solution, not sure.
