Hi all, Im getting the error while converting xml to a dataset.Please help me. Im converting xml file to dataset using the following code.

TextWriter twHistory = new StreamWriter(location + ".xml"); twHistory.WriteLine(XMLdoc); twHistory.Close(); DataSet dsHistoryXml = new DataSet(); dsHistoryXml.ReadXml(location + ".xml");

Cannot add a column named 'PerUser': a nested table with the same name already belongs to this DataTable.

HI, I am having a string which is in xml format. i want to populate a dataset using the string. I used the following code . But it doesnt convert.Please help me.

stream = new StringReader(XMLdoc.ToString());

How did you bind the repeater control.Have you used #Eval("id") or databinde r.use the same in the linkbutton.

at the codebehind , Use item command method to get the commandargument(e.commandargument).you can now get the id.Now you can update the table.Why you have written the query in the page itself.Please prefer to write stored procedures.

Hi, You have to update the table with 'update tb_staff set Active=0 where ID=command argument'. Please send the id of the corresponding record to the link button as commmand argument.
