The gridview is not displaying when the page load even though I have bind the gridview with the datasource.... below is the code..

My page includes a button and a GridView bound to a LINQ data object which is bound to a table. when the page loads the gridview gets populated with the data and all work well. The button has an empty method, when I click the button I get en error message "Intenet explorer cannot display the web page" I put a break point at the begining of the method listed below but I get the error message before it gets there. If I remove the gridview than the button works well.

I am using UpdatePanels, but still data will be fetched whenever page loads. How can I handle so the dat will be fetched on ony for the grid which is being updated
I am trying to set a focus on a dropdown within GridView(gridViewDropDown class) when page loads:
if ($('select.gridViewDropDown').length)
{
alert("Found my dropdown");
//$('select.gridViewDropDown:first').focus();
setTimeout(function() { $('select.gridViewDropDown').focus(); }, 10);
}
I can see the alert which means that dropdown is found but it never gets a focus. What do I need to change here? I am using IE 6/7.
I do long and slow query to get data to my GridView and I got lot of data, but when I'm changing page it loads as slow as at the start, it loads full data again and again, how to load data once and use paging without data loading?

View 1 RepliesI have a master page 'Master1' and i have used a content place holder 'content1' and loads pages 'Page1' and 'page2' in the 'content1'. Is there any way to identify which page is loaded to the content place holder whether it is 'Page1' or 'Page2' dynamically.
View 2 RepliesI have a 20 PopupControlExtenders for 18 columns in a GridView. Every popup is has different content: HtmlSelect, HtmlAnchor, HtmlButton CheckBox etc. etc. -depending on the cell it is clicked on.
I'm using combination of DynamicContextKey, DynamicControlID and DynamicServiceMethod to populate these popups.
The problem is, when the grid is first loaded, all popups in all columns populate correctly. Problem arises when I flip a page in the gird. On the new page, the popup comes up, but there is no content. And NO error (like 500 or something). Now when I go back to the first page, no popup shows content here either. What am I doing wrong? Here is a sample ItemTemplate:

I have this div inside a repeater, where i set the class, onmouseover and onmouseout properties from code behind:
<div id="Div1" runat="server" class="<%# getClassProduct(Container.ItemIndex) %>" onmouseover="<%# getClassProductOver(Container.ItemIndex) %>" onmouseout="<%# getClassProductOut(Container.ItemIndex) %>">
codebehind:
public String getClassProduct(Object index)
{
int indexItem = Int32.Parse(index.ToString());
if (indexItem == 3)
return "produs_box produs_box_wrap overitem lastbox";
[Code]....
This code is fired initially, and after the page is rendered, it is called again, and executed again due to that js...
UPDATE: happens only in Firefox. On chrome, it works fine...

have an ASP.Net 2.0 (VB) application which connects (SQL Authentication) to SQL Server 2008. I publish the application to our intranet. The start page is frmMain.aspx. I RDP to a "neutral" PC (one like our users have) and the site loads fine the first time in. The users cannot bring up this application, however (it does not load--times out). They have been able to run this application before from this same intranet location and have not had problems. I have re-published the site, but this behavior continues.
View 2 RepliesWhat would cause a single webpage to load slowly? I have javascript within the <head> element. The html consists of 2 <div> elements and within these <div> elements are a bunch of <table> elements and that's it.
The functionality of this site is such that each <table> element contains data that during the "onload" event, these <table> elements are hidden. Each <table> elements is controlled by an HTML menu (the menu itself is an html table). When a menu item is clicked, it will either display or hide the <table> element depending on whether it is already displayed or hidden.
I have a created a web portal in multi-language. I put all the pages related to "english-language" in one folder (/english) and "arabic-language" in one folder. I didn't have a default.aspx in my root folder(wwwroot), its in /english folder. There is no
index.htm or default.aspx page in my root folder.I am very confused how can i redirect the default.apage when page loads. The default pages is stored in /english folder.
Does anyone have any problems with Page_Load being executed twice in Google Chrome?
It's a short question, i do not know what else to explain...
I have a simple asp.net page and in Firefox and IE all it's working fine.
But in Chrome the Page_Load is fired twice...
Later EDIT:
- what is strange is that i have 4 repeaters... binded with random values. The random methods are twice fired (because of page loaded twice) but the repeaters takes the INITIALLY values...so, the 2nd post back is somehow raised after the rendering step.
3rd edit: It happens ONLY at the refresh!
Solution (in my case): There was an empty img src, and that was the cause
In my global.asax file for my ASP.net project, I am checking for certain conditions. When those conditions are met, I want to automatically execute javascript code when the page runs.
This is my code:
if condition Then
Response.Write(" < script type=""text/javascript"" > ")
Response.Write(" // Javascript code to do stuff ")
Response.Write(" < /script > ")
End If
While this appears to work to execute the Javascript code, I don't think it's a best practice because this code will preceed all of the HTML of the page that gets loaded.
What is the best way of programmatically tacking on some extra Javascript code to be run when my page loads?
I'm trying to update values from a xml file into textboxes. I have this javascript being called in the Page_Load event
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", sb.ToString(), true);
I click the continue button which does a post back but the values are not updated until I refresh the page again which makes me think the js isn't being run until after the page is returned. I'm wondering how to have the values updated when the page is refreshed after the button postback.
ASP.Net web forms, .NET 2.0
I have a dilemma. I have an aspx page that has a custom control:
<def:CustomControl ID="customID" runat="server" />
The custom control can be added multiple times to the ASPX page if certain criteria is met:
<asp:Repeater runat="server" ID="options" OnItemDataBound="options_OnItemDataBound">
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">[code]...
In the code behind of the aspx page, I wanted to append a event (OnSelectedItemChange) to the dropdown control that isn't actually on the ASPX page (yet). However, when I try to do something like the following in the code behind:
foreach(Control eachControl in customID.Controls) {
if (eachControl.HasControls) {
Control DdControl = eachControl.FindControl("optionValues"); //always null
[code]....
But All that eachControl has is a repeater, and it shows its childcontrol count as 0. So when it get to the FindControl method, it always returns null.
QUESTION.So what I am trying to do is add an event (OnSelectedItemChange) to the dropdownlist control inside the repeater (which is a custom control that gets added to the page if criteria is met). When a selection is made in the drop down, I want it to trigger the Event method.
How can I either: A) Find a way to add the event if the dropdownlist control exists on the page?
OR
B) A way to be able to call a method in the code behind and pass the selections from all the drop down lists (since the custom control could be added more than once creating multiple drop downs?
NOTE I don't have the code in front of me, so if I have something syntactically incorrect, please overlook. I also know that ID's are unique, so this is also assumed to be a problem with my logic. When it renders these, the ID's might be mangled by the asp name convention which I would assume I have to find a way around.
Here's is my code I just added to my DLL (using it in my website):
[Code]....
Then, in my page_load event, I just have:
[Code]....
I've added a reference to the dll and I've imported it in my page - the only other method (sub) works just fine, but with this, I get an error:Method not found: 'System.String HSIR_Common.Main.StripCurrentUser(System.String)'.
I have a few pages on my website that contain a gridview that gets bound on the page load event. Most of the time while the page is loading, about 5 or 6 rows of the gridview turn into a black box. Usually the box disappears after the page is fully loaded, but sometimes it doesn't and you have to highlight it with the mouse to get rid of it. This happens on more than one computer and I'm not sure how to fix it.

So how can i load the javascrip LoadArray() function onPageLoad in this scenario?
If the leave the webpage (any webpage) on my web application for a while (say 15 min), if I again click on another page it takes a long time to load (20 seconds)
I had a look through the google chrome --> developer module and found that, it is the web page which is the culprit here and the 'LATENCY' time for it is 17 seconds !!! and the actual 'download' time is only 117 ms.
A. what could be the cause of this issue?
B. What can I do to fix it?
