javascript - dataTable page length change issue -


I'm using dataTable 1.10, everything works well, but I found the following status The datatable does not support this behavior.

By default, I set the length of the page to 10, then I click on the next page, the items displayed in Table 11 to 20. Now I change the page length to 25, display the table item from 11 to 35. This is not my point. Whenever I change the length of the page, I want to display it from 1 item.

Is it possible to handle page length change events in datatable and customize that function?

Thanks for reading Hope you get help. 

  var tableHDR = '& lt; Table cellpadding = "0" cellspacing = "0" range = "0" square = "display" id = "alertlit" & gt; '+' & Lt; Thead & gt; & Lt; Tr & gt; + & Lt; Th & gt; Level & lt; / Th & gt; & Lt; Th & gt; Monitor name & lt; / Th & gt; & Lt; Th & gt; Alert message & lt; / Th & gt; & Lt; Th & gt; Raised top & lt; / Th & gt; & Lt; Th & gt; Action & lt; / Th & gt; '+' & Lt; / Tr & gt; & Lt; / Thead & gt; & Lt; / Table & gt; '; $ ('#view_content') Html (tableHDR); // global variable total = $ ('#lertlist').

Try it out, I found it from a data forum. 

  var t = $ ('# table-id'). Datable (); $ ('# Length li'). Click (function () {redrawWithNewCount (T, this.id);}); Function redrawWithNewCount (t, row_count) {// DataTables source greater or less right from var oSettings = t.fnSettings (); OSettings._iDisplayLength = parseInt (line path, 10); T._fnCalculateEnd (oSettings); / * If we have space to show additional lines (backup from end point - then do this * / if (oSettings.fnDisplayEnd () == oSettings.fnRecordsDisplay ()) {oSettings._iDisplayStart = oSettings.fnDisplayEnd () - oSettings ._iDisplayLength; if (oSettings._iDisplayStart & lt; 0) {oSettings._iDisplayStart = 0;}} If (oSettings._iDisplayLength == -1) {oSettings._iDisplayStart = 0;} t.fnDraw (oSettings); Return T; }

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! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment.
