Gridview Customised Delete action

[Rabbit]

Hi,

I'm having a GridView with Datasource being set from CodeBehind method, its
has a "RecID" databound field set as invisible.

I want to utilize the "Delete" commandfield, so that on gridview_RowDeleting
event, i can perform a customised delete action.

I've tried me.gridview.Rows(e.RowIndex).Cells(intField).Text, which only
works for "visible" field

My problem is now on such RowDeleting Event, I don't know how to access such
invisible "RecID" databound field, can anyone tell me what should i do for
achieving such field's value?

A GridView doesn't count invisible columns as real columns... so you
have to go directly to the data.

When in debug mode, set a breakpoint in the RowDataBound method (which
yuo assigned to that event).

Look for something like the following
(string)((DataRowView)e.Row.DataItem)[1]

This will get you the information in that column...

Thanks, I have just found another way to retrieve that invisible column,
because its my Data Key of the record, so I set the "DataKeyNames" attribute
of the GridView

then on the RowDeleting event, i can use following syntax to retrieve it!
Me.gvMaterialPO.DataKeys.Item(e.RowIndex).Value

Yeah that'll work too... point is that you can't just access the
column. You have to do it via data.
