c# - Dynamic Div creation asp.net -

-

I'm trying to dynamically create div on the bilateral button click.

For this, I link it to & gt; & Gt;

and the code was formatted as follows on the server side (.cps page) & gt; & Gt; 

  public fixed int i = 0; Protected Zero Button 1_Click (Object Sender, EventArgs e) {i ++; HtmlGenericControl newControl = New HtmlGenericControl ("div"); NewControl.ID = "newcroll" + i; NewControl.InnerHtml = "This is a dynamically created HTML server control."; PlaceHolder1.Controls.Add (newControl); }   
 This code was giving me one division every time when I pressed the button, I wanted to be apart of divs.  
 I tried using Javascript on the client & gt; & Gt;  
  & lt; Body & gt; & Lt; Form id = "form1" runat = "server" & gt; & Lt; Div & gt; & Lt; ASP: Button ID = "Button 1" Runat = "Server" OnClick = "Button 1" link "Text =" Button "On-clientClick =" addDiv (); "" / 
  asp: place holder id = "place holder 1" run = "server">   gt; script type = "text / javascript" & gt; function addDiv () {warning ("controls in the function"); Var r = document.createElement ('div'); R.style.height = "20px"; R.style.width = "25px"; r.appendChild ("div"); Warning ("Control out of function"   
 These two do not work.  
 What's wrong with me?  
 What Any bug   
 
 
 Use this  
  public index index { Receive (viewstate ["index"] == zero) {seestate ["index"] = 0;} and {viewstate ["index"] = int. Purse (viewstate ["index"]. Toasting ()) + 1;} return int.Parse (seestate ["index"]. ToString ());}} Secure Zero Button 1_Click (Object Sender, EventArgs e) {HtmlGenericControl newControl = new HtmlGenericControl ("div"); NewControl.ID = "newcroll" + index; NewControl.InnerHtml = "This is a dynamically created HTML server control."; PlaceHolder1.Controls.Add (newControl); }

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
