Hello All,
I am stuck on a conversion problem. I am trying to convert my
application which is written in VB.NET to C# because the project I am
working on currently is being written in C#.
I tried my best to convert it, but somehow the app does not work. I am
also not getting any errors when I complie thus, letting me know I am
on the write track. Basically what I want to do is edit,add,delete , and
update an XML file in a DataGrid. Below is my Code in
sub LoadXML
Dim objdata as New DataSet
Dim customer as String
customer = CustomerDropDow n.SelectedItem. Value.ToString
temp.Text = customer
Try
objdata.ReadXML (Server.Mappath ("/Secured/XML/"+customer+".xm l"))
datagrid1.Datas ource=objdata
datagrid1.Datab ind()
Catch
CreateXML
End Try
End sub
Sub CreateXML
Dim objdata as New DataSet("Indian Master")
Dim dt as New DataTable("Prod uct")
Dim dr as DataRow
Dim customer as String
customer = CustomerDropDow n.SelectedItem. Value.ToString
temp.Text = customer
dt.Columns.Add( New DataColumn("NAM E"))
dt.Columns.Add( New DataColumn("SKU "))
dt.Columns.Add( New DataColumn("PRI CE"))
dt.Columns.Add( New DataColumn("TYP E"))
dr=dt.NewRow()
dr(0)="No Data"
dr(1)="No Data"
dr(2)="No Data"
dr(3)="No Data"
dt.Rows.Add(dr)
objdata.Tables. Add(dt)
datagrid1.datas ource=objdata
datagrid1.datab ind()
objdata.WriteXM L(Server.mappat h("/Secured/XML/"+customer+".xm l"))
LoadXML()
