You can use AJAX[^] and send request to server from JS.

Nested Gridview with UpdatePanel

22-Jul-09 17:24

I suggest you buy a book on ASP.NET and read it. Once you understand the seperation between client and server, buy a good book on AJAX, and read that. AJAX is how your client can contact the server and grab information it returns.

hi,

i have a problem why is it that the updatepanel doesn't work on nested gridview or maybe i've just got a wrong code here.

the problem is whenever i click edit linkbutton of gridview2,
it will go back to gridview1, instead it should open the edittemplate of gridview2.

1.ScriptManager<br />
  a.UpdatePanel<br />
     :gridview1  ->nested to gridview2<br />
         :gridview2

block of code:

<asp:ScriptManager ID="ScriptManager1" 
   runat="server" AsyncPostBackTimeout="360000">
</asp:ScriptManager> 
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate >
  <asp:GridView ID="gridview1" runat="server">
   <Columns>
    <asp:TemplateField>
      <ItemTemplate>
      <asp:Label ID="lblHachoNum" runat="server" 
        Text='<%# Bind("Hacho")%>' ></asp:Label>
      </ItemTemplate>
      <EditItemTemplate>
        <asp:Label ID="lblHachoNum" runat="server" 
        Text='<%# Eval("Hacho") %>'></asp:Label>
      </EditItemTemplate>
    </asp:TemplateField>
    <asp:TemplateField>
      <ItemTemplate>
         <asp:GridView ID="gridview2" runat="server">
         <Columns>
            <asp:TemplateField >
              <ItemTemplate>
               <asp:Label ID="lblKubunNum" runat="server" 
                Text='<%# Eval("Kubun") %'       
                ></asp:Label>            
              </ItemTemplate>
              <EditItemTemplate>
               <asp:Label ID="lblKubunNum" runat="server" 
               Text='<%# Eval("Kubun") %'
                 ></asp:Label>
              </EditItemTemplate>
           </asp:TemplateField>
         </Columns>       
         </asp:GridView>

ViewstateEnabled=False

Re: ViewstateEnabled=False

22-Jul-09 14:39

Hi,

There are two textboxes and one button control in a Web page. We change the setting as ViewstateEnabled=False to both the textboxes. In button click event we have written the code to display TextBox1 value in TextBox2.

The value is displaying in TextBox2 as well as it didn't remove from TextBox1 also even if both the textboxes ViewstateEnabled=False. What is the reason? Please answer.

Thanks in advance

Well, the value you are seeing in text box are not loaded from viewstate. It will be loaded from the post back data. When you press the button, all the control values in the form will be send to server. When page renders, ASP.NET is capable to assign the values back to each controls correctly.

To see viewstate in action here, consider changing some properties of text box in page_load event. When viewstate is disabled for text box, you can see the changed property details are not persisting across post backs.

For the answer, first of all you need to know what actually happened during ASP.NET Page life cycle and ViewState.
In the ASP.Net page life cycle, two events related with View State.
1. Load View State : Where view state data is loading for the control and which happened before Page_Load.

2. Save View State : Where control data store in a hidden field before the Page_Render.

Now, If you disable the ViewState for the control it should store the view state data but, you are saying in Textbox, after you disabled the view state , control holds the data after postback,
Here is the Trick,
There is another event fired during Page Life Cycle, which is, Load PostBack Data Smile | :)

ASP.NET controls which implement IPostBackEventHandler will load its value from the appropriate postback data.
This value is not read from view state but from Postback From and this is true for those control which implements the IPostBackEventHandler
and TextBox is one such control Wink

Hope this clears your doubts and This will helps you.

ASP session in ASP.NET page

Re: ASP session in ASP.NET page

Hi
What is the difference between ASP session and ASP.NET session and how we use ASP session in ASP.NET page?

Thanks in advance

Christian Graus22-Jul-09 15:12

Re: ASP session in ASP.NET page

22-Jul-09 15:12

One is in ASP and one is in ASP.NET. You can't. You need to create some sort of intermediary, probably a windows service, to pass values between ASP and ASP.NET.

How to secure web.config file

If the server is not on your network, you can't, unless they offer a webservice to do it through, or a VPN.
