c# - Gridview sort reveals far more than anticipated! -

-

I need some help here, I am currently making goals in the circle.

I have a gridview 

  protected void btnSubmit_Click (object sender, EventArgs e) {if (radTopx.SelectedValue == "" || txtbxHowMany.Text == "" : That a radio button is filled with item based on the selection of the item) {MessageBox.Show ("Please make sure that both the 'appropriate number of product' is selected and selected before you run X Effort "," Top X Error !!! ", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); GridView1.DataSourceID = Faucet; GridView1.DataBind (); } And {int max = 0; If (int.TryParse (maximize txtbxHowMany.Text, outside)) {GridView1.DataSource = this.GetMaterialData (session "[MemberKey"] toString (), radTopx.SelectedItem.Value, "Primary", Max.); GridView1.DataSourceID = string.opt; GridView1.DataBind (); }}}

Where is GetMaterialData code: 

  Private Object GetMaterialData (String MemberKey, String MaterialType, String MaterialLevel, Calculate Integer) {ORWeightsDataClassesDataContext db = New ORWeightsDataClassesDataContext (); On query = db.tblOnlineReportingCOMPLETEWeights .Where (x => x.MemberId == MemberKey & amp; x.MaterialText == MaterialType & amp; x.MaterialLevel == MaterialLevel) .OderByDescending (X = & Gt; x.ProductPercentage). (Calculation); Return query; }

When it's run in the first example, it's running fine and okay ... good.

However, when I try to sort the gridview, the data changes and returns to bring all data set from its data source.

here html & amp; Back to code for # gridview: 

  & lt; ASP: GridView id = "GridView1" runat = "server" AutoGenerateColumns = "false" style = "z-index: 1; left: 215px; top: 560px; condition: full; height: 133px; width: 755px ; Text-line: center; "font-size =" x-small "onpageindexchanging =" GridView1_PageIndexChanging "onsorting =" GridView1_Sorting "Allow Paging =" True "AllowSorting =" True "& gt; Protected Zero GridView1_PageIndexChanging (Object Sender, GridViewPageEventArgs E) {GridView1.PageIndex = e.NewPageIndex; GridView1.DataSourceID = "lqPackWeights"; GridView1.DataBind (); } Secure Zero GridView1_Sorting (Object Sender, GridViewSortEventArgs E) {GridView1.DataSourceID = "lqPackWeights"; GridView1.DataBind (); } Anyone have any idea how can I make sure that when the gridwave is sorted, the original viewstrate is maintained?

You need a check in both your GridView 1_PageIndexChanging and GridView1_Sorting functions, to see if The user has done anything with the Radtext x or txtbxHowMany. If so, you will use the return value of GetMaterialData (), otherwise you will use "lqPackWeights" DataSourceID.

So you need everyone, it only takes a little more code to handle all the different situations that may arise.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...
