Save DataGridView to XML
Jan 6 2010 4:41 AM
Hello All
This issue has got to do with saving and retrieving data from xml into DataGridViews and vice versa
My xml file would look like this
<?xml version="1.0" encoding="utf8" ?>
<TestDescription xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" DeviceName="
Three phase meter1

</TestStep>

</TestStep>
<ValidationCriteria>if setCTRatio == getCTRatio testResult.valid = true else testResult.valid = false end</ValidationCriteria>
<ValidationError />
</TestCase>
</TestGroup>
</TestSuite>

</TestDescription>
As you see above there are sections for Descriptions , CommunicationDescription, TestSteps and TestParamters
For each of the above sections i have a separate data grid view and a separate dataset (ds , ds1, ds2, ds3) in my app. I am able to populate the data grid views properly but i am unable to save the modified datagridview into xml . How should i do this ? And since the data is spread over many data grid views , this is more confusing coz i have many data sets each pertaining to one datagridview.
I made a few changes to the "communicationDescription" and used "ds1.AcceptChanges() ". It did not save . Using WriteXML () did save but the file got completely erased . Check my code .. Dont think it is any where close to correct
if (ds1.HasChanges() || ds2.HasChanges() || ds3.HasChanges() || ds.HasChanges())
{
DescriptionMode mode = (DescriptionMode)Enum.Parse(typeof(DescriptionMode), CurrentNavigation);
string[] files = Directory.GetFiles("D:\\TFS\\Code Snippets\\TestController\\TestController\\bin\\Debug\\" + mode.ToString(), "*.xml");
String file = files[overviewClickedRowIndex];
ds1.WriteXml(file);
ds2.WriteXml(file);
ds3.WriteXml(file);
ds.WriteXml(file);
}
Any help will be greatly appreciated. Thanks! Please respond asap..
