# när jag jobbar med code behind

## #1 — Smultron, 2003-12-09T21:56Z

Jag gör en sida i ASP.NET C# och just nu har jag ett problem, jag har en knapp som när man trycker på den ska man sätta alla paneler till Visible= false;
finns det något bra för att göra det, nu måste jag sätta varje panel till false för sig....

jag jobbar med att försöka göra om en .aspx sida till codebehind också, hur ska jag göra med denna koden för att få den att fungera som codebehind?

```php
<script language="C#" runat="server">
			void butt_company_down( Object Sender, EventArgs ea)
			{
				pan_company.Visible= true;
				pan_occupies.Visible= false;
				pan_payment.Visible= false;
				pan_customers.Visible= false;
				pan_prod.Visible= false;
			}	
			
			void butt_occupies_down( Object Sender, EventArgs ea)
			{
				pan_company.Visible= false;
				pan_occupies.Visible= true;
				pan_payment.Visible= false;
				pan_customers.Visible= false;
				pan_prod.Visible= false;
			}	
					
			void butt_payment_down( Object Sender, EventArgs ea)
			{
				pan_company.Visible= false;
				pan_occupies.Visible= false;
				pan_payment.Visible= true;
				pan_customers.Visible= false;
				pan_prod.Visible= false;
			}	
			
			void butt_customers_down( Object Sender, EventArgs ea)
			{
				pan_company.Visible= false;
				pan_occupies.Visible= false;
				pan_payment.Visible= false;
				pan_customers.Visible= true;
				pan_prod.Visible= false;
			}	

			void butt_prod_down( Object Sender, EventArgs ea)
			{
				pan_company.Visible= false;
				pan_occupies.Visible= false;
				pan_payment.Visible= false;
				pan_customers.Visible= false;
				pan_prod.Visible= true;
			}	
			
		</script>

Det här skall ordna problemet med panelerna.

```
private void Page_Load(Object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      ViewState["panel"] = "1";
      pnl1.Visible = true;
   } 
}

void change_panel(Object sender, EventArgs e)
{
   //Hide current visible panel
   ((Panel)Page.FindControl("pnl" + ViewState["panel"].ToString())).Visible = false;
      
   //Show chosen panel
   string a = ((Button)sender).CommandArgument;
   ((Panel)Page.FindControl("pnl" + a)).Visible = true;
   ViewState["panel"] = a;
}
```

```
<asp:button id="bt1" text="1" commandargument="1" OnClick="change_panel" runat="server" />
<asp:button id="bt2" text="2" commandargument="2" OnClick="change_panel" runat="server" />
<asp:button id="bt3" text="3" commandargument="3" OnClick="change_panel" runat="server" />
<asp:button id="bt4" text="4" commandargument="4" OnClick="change_panel" runat="server" />

<asp:panel id="pnl1" visible="false" runat="server">
aaa
</asp:panel>
<asp:panel id="pnl2" visible="false" runat="server">
bbb
</asp:panel>
<asp:panel id="pnl3" visible="false" runat="server">
ccc
</asp:panel>
<asp:panel id="pnl4" visible="false" runat="server">
ddd
</asp:panel>
```
