According to my knowledge i gather some steps to develop good performance applications in ASP.NET

1)Use the string builder for concatenation

2)Try partial page submission

3)Try to reduce the round tips with database

4)Try to reduce usage of viewstate

5)Avoid storing the too much data into session variable  and maintain session variable timeout property

6)Before deploying put  debug=false in web.config

7)Use the finally block along with try and catch blog to close the connections and close the files 

8)Do the validations at client side

9)Use is Page.IsPostBack to reduce unnecessary code calling

10) Try to maintain return statement to methods

11)Foreach loop is preparable compared with for loop

12)Use ArrayList instead of Array

18)Return multiple result sets in a single database request

19)Close or dispose the connections after usage of database connection

20)Better to use Where conditions in select , Insert  and update queries 

21)Do not use the command builder at run time and better to use sqlcommandbuilder and oldbcommandbuilder

22)Use the stroedprocedures

  Be sure to use CommandType.StoredProcedure instead of CommandType.Text

23)Before you deploy your application , you must set tracing state as disable .

24)User server.transfer instead of response.redirect.

25)Use Cache:

Page output caching.

Page fragment caching.

How to call the ASP.Net Button click logic from model pop up Using  java script

JavaScript code

 function SubmitClick() {
                document.getElementById('text').innerHTML = "Do you want to continue ?";
               $('#divSubmitPopup').dialog({
                autoOpen: false,
                width: 300,
                height: 'auto',
                modal: true,
                resizable: false,
                draggable: true,
                autoResize: true,
                title: 'SamplePopUp :',
                position: 'center',
                buttons: {
                    "Continue": function () {
                        $('#btnSubmit').click();
                     
                    },
                    "Cancel": function () {
                        $(this).dialog("close");
                    }
                }
            });

            $('#divSubmitPopup').dialog('open');


        }

Html Code
                     
        <asp:Button ID="btnSubmit" runat="server" CssClass="button" Text="Submit" Style="display: none" OnClick="btnSubmit_Click" />

       <input id="htmlSubmit" type="button" value="Submit" runat="server" class="button" onclick="javascript:SubmitClick();" />

Points to Remembering
1)From html code call the function and implement the logic under function in javascript
2)Call the asp.net button from that logic .
please observe the above code then we can easily understand

How to read the data from GridView control 

ASPX.CS

       

foreach (GridViewRow row in gvAns.Rows) 

                        {

                            TextBox txtbox = (TextBox)row.FindControl("txtAnswer");

                            string str = txtbox.Text;

                       }

ASPX

  <asp:GridView ID="gvAnss" runat="server" AutoGenerateColumns="false" GridLines="None"

                        EmptyDataText="No records found" Visible="false" ToolTip="Answers">

                        <Columns>

                            <asp:TemplateField  Visible="true">

                                <ItemTemplate>

                                        <asp:TextBox ID="txtAns" runat="server" TextMode="MultiLine" 

                                        Text='<%#Eval("Ans")%>' CssClass=" editable stions">                       </asp:TextBox>

     

                                </ItemTemplate>

                            </asp:TemplateField>

                        </Columns>

                    </asp:GridView>

Note:

gvAnswers is id of GridView  control 

txtAnswer  is id of TextBox control

Here data inserted into gridview then read the data from gridview 

GridLines="None" property dosn't show gridlines
