asp.net : Add confirm delete to a GridView delete button

C#

OnClientClick='<%# "return confirm(\"do you want to delete " + Eval("Name") + "\")" %>'>

Visual basic

OnClientClick='<%# "return confirm(""do you want to delete " + Eval("Name") + """)" %>'>

using the onclientclick event of the button, linkbutton, or imagebutton control, we can add the confirm javascript function.


for each double quote closing or opening a string, we need to add the escape character \. The Eval function takes as a parameter whichever field name we need to display in the confirm section.





this technique has been around since .net 1.0, implemented in different ways. the onclientclick event is new in .net 2.0 and up, which makes it useful in this situation.

Comments are welcome
