Damnit, Jim. Where is my data?!

[Scott M]

I am binding an array of objects to a datagrid and storing an internal ID in
a hidden column in my datagrid for updating the database. All is well while
I'm testing it out. But, as soon as I turn the column's visible property to
"False" the data disappears!! I tried it with a template column AND a
databound column!! What gives? How do I retrieve the value?

Thanks
Scott

Hi Scott,

Welcome to ASP.NET newsgroup.
Regarding on the problem you met when try retrieving value from invisble
Column in DataGrid, it is caused by the DataGrid's processing on invisible
column. DataGrid won't render the content for Columns that are set to
invisible.
So for your secnario, if we need to store additional data in each row (to
be used latter in postback event), we can consider either of the following
means:

1. Still use TemplateColumn, but don't set the whole column to invisible,
but put a inner sub control (which hold the additional value) and set this
inner control to invisible. (I'll recommend the HtmlInputHIdden html
control) Then, in the postback event, we can use DataGridItem(or sub
cell)'s find control to retrieve the control and its held data.

2. all the Control instance in asp.net has the Attributes collection which
will be persisted in the ViewState by default. So we can also use this
collection(e.g, use the DataGrieItem's Attirbutes collection to store the
value we want). The storeing code can be put in the DataGrid's
ItemDataBound event.

Just some of my suggestions. Hope helps. Thanks,

Scott,

Setting the column's Visible property to false results in not sending the
column to the client in the first place. That's why you don't get any value
on postback. You should hide the column with css rule display:none.
