group:save DataGridView to Xml
c#:
Generally DataGrids are displaying data from a DataSet, you can save the data within a DataSet through the DataSet.WriteXml() method. The DataSet Class: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDataDataSetClassTopic.asp
Hello Gurus,
I want to save the state of an unbound DataGridView on my Windows Form application to an XML file so i can later load it back.. Basically, on my form I have a DataGridView, it's got some DataGridViewTextBoxCell, DataGridViewComboBoxCell etc, i want to export all that to XML.. Any help is greatly appreciated.
What i wanted to store was the value of those items, while i can iterate
create line by line the xml file, i would much rather use the dataset and WriteXml method, but for some reason i was not able to do so for an unbound DataGridView. the user creates the rows and sets the values, then when they click save, i want to output all the data to an XML file, idealy, i want to extract the DataSet of the DataGridView to save it to XML using the WriteXML method mentioned, but i was not able to get it. Do i make sense?

A DataGridView is a user interface component, not a data component. It is
bound to a DataSet by means of a BindingSource, which relates the data in a particular table or view in the DataSet to the DataGridView. The DataGridView then uses the BindingSource to display the data in a meaningful way. Therefore, you don't want to serialize a DataGridView at all; you want to serialize the data that is contained (or rather "displayed") in it. This would entail serializing the DataSet. As to why you were "not able to get it," that is the crux of the problem, and cannot be answered until you describe exactly what you tried, and what the results were. -- HTH, Kevin Spencer Microsoft MVP ..Net Developer Presuming that God is "only an idea" - Ideas exist.

ok, now we are getting somewhere.. i understand about the DataSet and the
bindingsource etc, but since i don't use a dataset to populate my DataGridView, i cannot extract the data to xml with the WriteXML method.. so what i was looking for was a way to extract a DataSet out of the DataGridView eventough it was not bounded, i know this doesn't makse sense.. let me explain a bit.. I create rows programatically, say after 10 rows have been created, i want to save that information to a file so that next time my application runs, the datagridview is populated again.. i think from the looks of it, there is no easy way to do it than to iterate and write each row information to an xml file and read it back to re-create the rows when the application starts up.. i was thinking there was an easy method to export/serialize the data out a datagridview.. any suggestions?

Hi , I understand what you're trying to do, and I agree it seems strangely clunky to move data back from the edited DataGridView. Given the excellence elsewhere it seems odd that we can't just say: dataGridView1.WriteXmlData(filepath/StreamWriter object) or .WriteUpdate I wish I could be of more help ; perhaps this will spark a response that does help more though :-) N
I'm looking to do the same thing. Using the datagridview as an input control and want to save to XML. Ever figure a way out or do you need to bind a dataset?
