How to diable buttoncolumn's

[Philip Yeo]

Just a question,

If I have a column that performs delete. But I want to disable all the
delete buttons in this column when user click's on edit,

I put this code here,

Protected sub mydatagrid_edit(sender as object, e as
datagridcommandeventargs)

mydatagrid.edititemindex = cint(e.item.itemindex)
' because it is in the 2nd col item's integer parameter is 1
dim btnDel as button = e.item(1).controls(0)
btnDel.enable = false
loaddata()

end sub

However this doesn't work.
So I figured that it could be because there's a whole row of the table that
has this button so the controls(0) is actually returning an array object.

Thus would it be wise to write the code this way. Pls advice if there's any
mistake

Protected sub mydatagrid_edit(sender as object, e as
datagridcommandeventargs)

mydatagrid.edititemindex = cint(e.item.itemindex)
' because it is in the 2nd col item's integer parameter is 1
dim btnDel() as button = e.item(1).controls(0)
dim i as integer
for i = 0 to btnDel.count
btnDel(i).enable = false
next i
loaddata()

end sub

Just a theory but... does your loaddata() function rebind the grid? If so, then
put the btnDel.enable = false after loaddata()

Yup,

Load data rebinds the dataset to the datagrid...

So your sorted now! Right?
you did try putting the btnDel.enable = false after loaddata()
