Forms Data Controls :: PreRender Takes Upto 13 Seconds?

Jan 8, 2010

At the first loading of my page, duration of PreRender takes upto 13 seconds. That page has basically a gridview control which bind to SqlServer query by SqlDataSource. When I execute query seperately, it takes only 0.02 second.

On the other hand, for the next loadings of same page by postback, duration of PreRender varies from 0.5 second to 3-4 seconds.

In addition to gridview, there are several dropdownlist, update panel, ImageButton in gridview. I use paging for Gridview.

Which strategy should i follow to increase performance of this page?

C# - AppFabric DataCacheFactory Initialization Often Takes 30 Seconds?

Nov 26, 2010

When I initialize my client to connect to AppFabric's cache, it seems to inconsistently take up to 30 seconds to connect on the following line:

factory = new DataCacheFactory(configuration);

See full Init() code below - mostly taken from here.I say inconsistently because sometimes it takes 1 second and other times 27, 28 , etc ... seconds. I have an asp.net site using the AppFabric cache - which lives on a different box (on the same domain). Everything is working great, except for the inconsistent connection time. When it connects, its all good - I just need to get it to consistently connect in ~1 second :)

public static void Init()
{
if (cache == null)
{
Stopwatch sw = new Stopwatch();
sw.Start();

Forms Data Controls :: DetailsView - PreRender Event Bug?

Mar 7, 2010

I have a DetailsView on my page, bounded throught ObjectDS (but I think it's not important). Some field is readonly for some users - based on role membership and other paramaters. I've tried to use the PreRender event to manage these field's readonly state. Everything is working - except one template field: when I click first time on Edit button the dropdown list stay readonly independently the role membership. When I click on Cancel than Edit again the control state is good. Code of PreRender event handler:

Forms Data Controls :: PreRender Content In ListView Missing In Excel Extract?

Jan 13, 2010

Whenever I try to export a ListView with formatting or dynamic content in the PreRender event to an Excel file, I lose all of the changes from the PreRender event. Here's the ListView code:

<asp:ListView ID="ListView1" DataSourceID="profileData" runat="server" DataKeyNames="ROW_NUM">
<LayoutTemplate>
<table cellspacing="0">
<thead>

[Code]....

I've done some reading and found that RenderControl possibly ignores anything in PreRender for a control, but I'm thinking there has to be a way to get those PreRender changes in there before extracting the ListView to Excel.

The only workaround I've found so far is to copy and paste all of my preRender code into the Page_Load, and then everything looks fine in Excel. However, then I have to duplicate my code, as I still need it in the preRender event to display it on the screen properly. I don't want to maintain the code twice.

Web Forms :: Extender Controls May Not Be Registered After PreRender?

Mar 8, 2011

I am creating Dynamic UserControls with Dynamic AjaxControls. Then I store each of the UserControls in a Collection. On Postback I recall the UserControls in the collection to Re-Create the interface. It works if i only use Standard HTML controls but does NOT work with AJAX controls. I get this error on PostBack Extender controls may not be registered after PreRender. So far I have tried the following:

MyBase.OnPreRender(e) in Page and Usercontrol EnsureChildControls() in the OnInit Added ScriptManager to the MasterPage None of this stuff is working... If I re-create all the controls including the ones inside the usercontrol then i get no error however it takes forever to do a postback as opposed to just recalling the collection of UserControls.

Web Forms :: Dynamic Controls Example. Script Controls May Not Be Registered After PreRender?

Mar 25, 2011

When creating dynamic ajax controls you may experience a pre-render issue on postbacks. You are supposed to re-create the controls on postback, however if there are very many of them performance gets very slow between each postback. i.e. clicking on a combobox, it may take several seconds. So what I did was group the controls in panels, store the panels in a collection, then re-call the panels on Postback. This actually works great if the controls inside the panel are standard html controls (textbox, dropdowlist, etc.). But...doesn't work well with ajax controls...yet.

I have included a sample below. Uncomment/Comment the code to test it.

Data Controls :: Gridview Paging Is Taking Some Time (15-20 Seconds) To Go To Next Page

May 7, 2015

I 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.

Nov 25, 2010

VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

C# - Binding Controls On PreRender?

Dec 17, 2010

I have been led to believe that the best point to bind your controls is the PreRender. As all the controls are ready and this is the last stage before rendering etc. Is this correct or should controls be bound at a different point?
