Hello
What is the best way to sort an XmlDocument for display in a DataGrig?
I can use Xpath with an XpathExpression , and a XpathNavigator. But this
XpathNavigator object is of no use to me, I need a XmlDocument. So is there
an easy way to convert an XPathNavigator object to an XmlDocument?
And I could use a piece of Xstl to transform the doc. But this seems like a
lot of work. I would have to load the Xslt from file, cache it, and apply it.
I also have not found an easy way to transform an XmlDocument in memory. It
seems it is all aimed at taking a disk file, and applying the XSLT from a
file,a nf write to a file.
Thanks for any help.

for sorting you dont need to use XPathExpression .. its normally used to do a
scan and get nordes that match a certain criteria.
if you want to sort it.
Create a Dataset
Use XmlDataDocument (with relation to the dataset).
Load the XML Document or a part of it (if so load the schema first)
At this step the dataset is populated with the xml data.
now you can apply dataset.tables[0].Select(sortcri teria) to fetch the sorted
order of datarows that can be imported into a table clone and can be
displayed in the datagrid

Thanks for your help
How do I get the XmlDataDocument into the Dataset?
Will this work without a schema? We get this data from another system, and
there is no Schema, I would have to create one.
This is also a lot of processing and memory usage. I am surprised XML
sorting is so hard to do...
Thanks again

i have just replied to another user with a complete example using xml, xsd
(for more info refer to post - Urgent help needed converting xmlnode to
dataset)
DataSet ds = new DataSet();
ds.ReadXmlSchem a(@"..\..\Custo mers.xsd");
// create matching xml data document
XmlDataDocument xdd = new XmlDataDocument (ds);
try
{
xdd.Load(@"..\. .\Customers.xml ");
}
catch(Exception ex)
{
MessageBox.Show (ex.Message, "Error Loading XML");
}
this.dgXML.Data Source = ds;
this.dgXML.Data Member = "CustomerDa ta";
hope this helps

DataSet.InferXM LSchema or just use the Schema designer in Visual Studio. This is also a lot of processing and memory usage. I am surprised XML sorting is so hard to do...
Not noticably more than applying a XLST transform.

Hi,
I have a C# Windows .net application (not asp.net) which

populated from a DataView, in which I specify a sort order

is able to then resort the data by clicking on any of the
datagrid column headings.
What I can't work out how to do, is to detect what new
sort order the user might have selected, i.e. what the

Hi,
I'm needing to update an xml file by inserting a new node. First I need to
load the xml into a XmlDocument from file.
In the first run, the file won't exist and I will have to create a new
XmlDocument. What is the best way to do this ?
I'm thinking just catching an exception and building a new doc isn't the
best way of doing this.

Hi
I have a question which I hope you can help with.
I am setting the DataSource of a DataGrid to be a DataView. I am sorting the
DataView by various fields which include a Date.
When I create a new row in the DataGrid and set the date to me within the
current sort range, the newly created row "jumps" to its correct position in
the grid. This obviously makes sense because it is following the sort rule.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
