I have Gridview control with all rows are edit mode using Itemtemplate and footer template. Some of columns are having ajax calendor control.
Page is very slow. If I am loading 500 rows into GridView
I am making some application in asp.net 1.1 in that I am displaying data in datagrid from database. In data grid first column is of check box and radio button and in the last column we have text box now thing is that when i click on check box crosponding textbox we fill some figure and at the end we press calculate button to get total. After getting total we have to press continue button to go next step
But suppose if some body remove that check the we should press calculate button or chnage some figure in the text box then we should press calculate button again to recalculate. for that i kept autopost back on check box oncheckedchanged event and text box ontextchanged event and hide continue button so user will click calcutae button abd then continue button will re-apper
Problem it that it taking too much refresh and taking long time. So was lloking for some ajax method to use in my application.

View 1 RepliesI had implemented the Ajax timer control to update Gridview data(along with Progress bar inside Gridview) after some interval of time.Below is the full code:
HMTL:
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<%--style & Script for progress bar in Gridview --%>
<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link href="css/jquery-ui.css" rel="stylesheet" />
[Code] ....
C#:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack) {
BindGrid();
} }
protected void BindGrid() {
string query = "SELECT * FROM Table";
[Code] ....
It is working fine except that the Gridview paging is taking some time(15-20 seconds) to go to next page.
i have a loging page, once i login into my application it is redirecting into main dash borad screen. where i am displaying data from other server. it is taking time to load page..
case 1:- in my dashboard one block i am displaying some simple info like alerts, news, mails count..etc.. that is comming from my local database ( there is no performance issues on that..)
case 2: in the same page (dashboard block) i am showing data, it is comming from another server.. first it will check the credentials and retrive data and displaying in same dashboard screen ( here it is taking time)
once hit the login button and redirecting into a dashbard screen using response.redirect("dashbard.aspx"); it is redirecting to dashbard screen..once all the process of page load is comple,,,then it is displaying the dashboard page what i am looking is first i want to redirect to the dashboard screen and then process the case1 ( simple data ) ..and for case2 i just want to show some ajax spinner image on the second block..
I know you can do paging in gridview but is there a way which allows u to load one page ie page 1 and then when the user select page 2 it loads that page...because I will have 100,000 rows and I dont want to load all of them.. But I need to show all, so is there a way which u can do paging which allows u to load a page at a time?

I am retrieving records from database nearly 380 records and binding them to a repeater control.My page is taking long time to load. how to improve the performance and here is the code of my repeater.
I have an application which imports data from csv to sql server 2005. It is taking long time to import data from csv to sql server 2005. it has a timer. on tick of timer, I am checking if current rown in csv exists in database. If it exists, It is not added to sql server otherwise, It is added that row to sql server 2005. Also, In page load, It checks on each tick, whether user is logged in or not. it adds value to log file that user is logged in. How can I optimize this ?
View 1 RepliesI have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
I am having a Gridview which takes much time to load its data, I tried to make the loading faster by implementing paging in gridview and reducing the rows to render in the grid and it got worked to an extent but still it lags in processing to bind data. The database i am using is SQL Server 2005 and the code is as follows
DataTable dtProducts = objProducts.GetProductDetails(iCat.ToString(), userId);
dgrdProductList.DataSource = dtProducts;
dgrdProductList.DataBind();
public DataTable GetProductDetails(String CatID, String UserID)
{
DataAccess DAB = new DataAccess();
DataTable dtbProducts = new DataTable();
try
{
string SQL = "select *,CAST(ShortDescription AS varchar(200)) AS ShortDescriptionList from vw_products where IsActive=1 AND CategoryID = " + CatID +
" AND LanguageID in( SELECT PW_UserLangRel.LanguageID FROM PW_Language INNER JOIN " +
" PW_UserLangRel ON PW_Language.ID = PW_UserLangRel.LanguageID WHERE PW_Language.IsActive=1 AND PW_UserLangRel.CompanyID=" + UserID +
" ) Order By ID Desc,LanguageID";
dtbProducts = DAB.Fill(SQL, CommandType.Text).Tables[0];
}
catch (Exception ex)
{
throw new Exception(ex.Message + "WebShopPaolo.CProducts.AddProductImages");
}
return dtbProducts;
}

When I run my routine it inserts the gridview twice in the spreadsheet, the second one immediately to the right of the first table...

It renders perfectly on the page by using the following commands:
