asp.net - cannot change GridView Caption -

-

Changing this gridview seems impossible. Captions after it is set once.

Once I set the caption and then change it to postback, all in the code look ok, page prerenders, gridview prerender and wherever

I do not know - Page (And also gridview) Preorder Event while debugging. The caption is fair, but it renders with the old caption also

The page appears to be presented once with caption, although I changed it is.

I also tried to replace it, to update and update the panels, but did not get help from this.

Can someone suggest? Thanks in advance.

In this example, it seems to work here, can you post your code? 

  & lt;% @ Page language = "C #"%> & Lt ;; DOCTYPE HTML PUBLIC "- // W3C // DTT XHTML 1.0 Transcription // N" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> & Lt; Script runat = "server" & gt; Protected Zero Page_load (object sender, event events e) {if (IsPostBack) {System.Collections.Generic.List & lt; Int & gt; Value = new system oath. GenericList & lt; Int & gt; {1, 2, 3, 4, 5, 6, 7}; GrdTest.DataSource = Value; GrdTest.DataBind (); }} Secure void btnSubmit_Click (Object Sender, EventArgs e) {grdTest.Caption = "test grid" + DateTime.Now.ToString (); } & Lt; / Script & gt; & Lt; Html xmlns = "http://www.w3.org/1999/xhtml" & gt; & Lt; Head runat = "server" & gt; & Lt; Title & gt; & Lt; / Title & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Form id = "form1" runat = "server" & gt; & Lt; Div & gt; & Lt; Asp: GridView id = "grdTest" caption = "test grid" runat = "server" & gt; & Lt; Columns & gt; & Lt; ASP: TemplateField & gt; & Lt; ItemTemplate & gt; Hello & lt; / Item theme & gt; & Lt; / ASP: TemplateField & gt; & Lt; / Column & gt; & Lt; / ASP: GridView & gt; & Lt; ASP: Button ID = "BTN Sebuit" Runat = "Server" onclick = "btn submit_click" text = "submit" /> & Lt; / Div & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt;

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
