Hi,
This might be the easiest question ever but I can't seem to find how to do
it: I have a DataGrid that's linked to an instance of IList (actually, it's
an ArrayList). On load, there's already data in the collection so when I
call the DataGrid's 'SetDataBinding ' method, the DataGrid displays the data
correctly.
Problem is that when I add data to the collection afterwards, I can't
display it in the DataGrid. I tried calling its 'Refresh' method, its
'Update' method and even the 'SetDataBinding ' method again without success.
Basically, in this case, how can I refresh the data in a DataGrid once the
source has changed?
Thanks,
SC

SC,
You could set the DataSource of the grid to null, and then back to the
list. This is the hacky way.
If you wanted the grid to update when changes are made, then implement
the IBindingList interface, which has an event that you fire when changes
are made to your list.
Hope this helps.

Hi --
I'm very, very new to ASP.Net, and I've been trying for several days to
figure out how to update a datagrid AND refresh it on the client side so
that the page doesn't refresh. I've torn my code apart over and over each
time I tried what I thought would be the code that would solve my problem.
Maybe I'm going down the completely wrong path here. Essentially,
here is an explanation of my ASP.NET webform application and what I

If you have a datagrid with an underlying dataset and rows are added to the
dataset during a program run, how do you get the datagrid to update itself
to repflect the changes in the underlying dataset? I've tried Update() and
Refresh() but these don't seem to work. Only thing that works is rebinding
the datset to the datagrid control, but this doesn't seem to be quite right.

hi,
In my Datagrid i have some text and a image (for each item), if i edit
the image and save it to the HD there's no problem, but the image is always
saved with the same name (item number.jpg) so after the change the datagrid
does'nt refresh the image because her name did not change.
My question is : Is there a way to "refresh" the datagrid after the edit
function, to refresh the image ?

Hey guys, please HELP
I am going nuts with the datagrid control.
I cannot get the damn control to refresh. I am using soap to get information
from a web service. I have an XML writer output the file to a folder, and
then I read it back into the dataset using the dataset1.readxml. Up to this
point, everything works wonderfully. The query executes, the dataset gets
populated, and I get the results displayed in the datagrid.

I have a Form that has 2 OleDbAdapters and one dataset object.
In the dataset I have two tables that are joined.
My datagrid is looking at one table.
I add new records to the datagrid.
I want to be able to reload the datagrid or refresh the contents of the
datagrid.
Problem is that when I refresh the dataset it also refreshes the other
table.
How can I reload...refresh the datagrid without using the dataset object.

Hi all,
I'm having a weird time with a call to the Refresh() method of a
DataGridView. I have a VB.NET 2005 Windows application with a main form and
a "worker" thread. The main form delegates a Sub to the worker so that the
latter can refresh the DataGrid after updating the DataTable driving it.
When I run the app under the debugger, everything's fine. But when I run it
for real, it hangs, apparently in the Refresh() method of the...
