c# - no row at position zero after loop -


Text after "

I need help with the following: 

  foreach (dt.rows in DataRow Dr.) {Preparation Document (Dr.); } // Try updating table table entries {string constring = "........"; String query = @ "updated processed set OnSiteWorkTx = 1 where VisitNumber = @company and processed = 0"; (Using SqlConnection conDatabase = new SqlConnection (constring)) (SqlCommand cmdDatabase = New SqlCommand (query, conDatabase)) {cmdDatabase.Parameters.AddWithValue ("@ Company", MyVariable); ConDatabase.Open (); CmdDatabase.ExecuteNonQuery (); }} Hold (Exception preceded by) {Response.Write (ex.Message); }

inside PrepareDocument I have the following: 

  Private Zero PrepareDocument (DataRow Dr.) {string connectWrk = ".. ......... "; Using (SqlConnection connWrk = New SqlConnection (connectWrk)) {string queryWrk = '+ MyVarible + "" OnSiteWorkTx where VisitNumber = Select Workdone' '; SqlCommand cmdWrk = New SqlCommand (queryWrk, connWrk); Var ds = new dataset (); Var da = new SqlDataAdapter (cmdWrk); Da.Fill (DS); Var WorkDonon = Databables [0]. Roof [0] ["Workdon"]; Try {connWrk.Open (); TableWrk.AddCell (cellWrk); TableWrk.AddCell (Workdone.ToString ()); } Hold (ex before) {Response.Write (ex.Message); }}}

To change table entries in the processed state, the code is going to be written before ready document (Dr.) , then the processed process can not get the entry It is now true and the error returns zero poster at zero.

Try the following: 

  if (ds.Tables.Count & Gt; 0 & amp; amp; amp; amp; ds.Tables.Rows.Count> 0) {var Workdone = ds.Tables [0] .Rows [0] [0]; ...

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module!
