Get datagrid item text

[martin]

Hi,

I am iterating through the dataitems in a datagrid and producing and xml
document,
If a particular cell in the datagrid has a textbox control or a datagrid
control in it then I have no problem retrieveing it value by casting with
CTYPE

however when the datagrid cell contains no control, but does contain text,
then I am having great trouble accessing its value.

can anybody please help me out.
I have provided the code I am stuc on below.

cheers

martin.

Dim di As DataGridItem
For Each di In dgOtherMemberships.Items
counter = counter + 1
If di.ItemType = ListItemType.AlternatingItem Or di.ItemType =
ListItemType.Item Then
elem = doc.CreateElement("Item")
elem.SetAttribute("PKID", --WHAT GOES HERE TO RETRIEVE THE
TEXT OF A DATGRID CELL) <----------Having trouble with this cast...???
elem.SetAttribute("membership",
CType(di.FindControl("Member"), CheckBox).Checked)
elem.SetAttribute("Accredited",
CType(di.FindControl("Accredited"), CheckBox).Checked)
elem.SetAttribute("membershipCode",
CType(di.FindControl("MembershipCode"), TextBox).Text)
rootElem.AppendChild(elem)
End If
Next

di.Cells[0].Text would give you the text of the first column in the
grid, etc. Fill in the appropriate index.

BTW, if you were using a TemplateColumn for this 'text column', then you
could have used a LiteralControl in this column instead of plain text,
and you could then do something similar to what you do for the controls
(.FindControl...).

Thank you craig,

maybe you could tell me if it is possible to bind the changed datagrid
values back to a datatable in dataset (or the like) in a single
statement, ---just like a bind from the dataset to the datagrid in a single
statement, only the other way around.

what I am doing at the moments is iterating through my datagrid producing a
custon xml file that I am passing to the database, so that all updates can
be done in a single call to the db.
