### Problems Positioning Popup Extender After Postback

Please read this entire post before responding and refer to the supplied screen shots to fully understand the problem. There are multiple layers of Ajax controls invovled. On the main page, I have Modal Popup Extender that displays a User Control. Within the User Control is a Popup Control that displays another User Control. User Control #2 which resides on User Control #1 is comprised of a GridView with sorting capabilities. I've got code in place that displays User Control #1 following a postback generated from within it. I've got additional code that displays User Control #2 (the one with the GridView) following a post back. The result is that when User Control #2 is sorted, it remains visible. The problem is that after the postback for User Control #2 ocurrs, the control is not displayed at the coordinates specified in the markup. If I hide it and then redisplay it, it will appear at the specified location. Protected Sub Page_Load() Handles Me.Load If TextBoxShowCompanyFacilitySelector.Text = "-1" Then Dim PopupControlSelectCompanyFacilityId As Object = FormViewContactDetail.FindControl("PopupControlSelectCompanyFacilityId") PopupControlSelectCompanyFacilityId.Show() End If End Sub These screen shots show the desired and actual behaviors.

### Problems With Formview.DataItemCount

Hello forum,

I have a formview, Fv, and a label, lbl.  I am trying to count the number of records in fv, in the Load_Complete event,  and place the number in lbl.  However, I keep getting "0" as my count, whether there's a record or not.  Where am I going wrong?  Here's my code behind:

Protected Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadComplete

lbl.Text = fv.DataItemCount
End Sub

### jQuery $(document).ready() and ASP.NET Ajax asynchronous postback Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore.$(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback. ### jQuery live() and ASP.NET Ajax asynchronous postback The issue is that normally$(document).ready() is called when the DOM is ready to be manipulated. But this doens't happen after an ASP.NET Ajax asynch postback occurs.

This means that the initial jQuery bindings won't be automatically available after the asynchronous postback is over. I underline "automatically" here because my last post describes more possibilities, how this issue can be worked around.

### Top .NET Performance Problems and how to avoid them

Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code

### Maintain HTML Radio Button Selection Inside GridView After Postback

Long time ago I wrote an article about getting the value of the selected RadioButtons inside the GridView control. The code did not addresssed the postback issue which means that the selected radio button was cleared after the postback occurs.

### Formview LinqData source not allowing updates

OK, I'm confused.  I've set up a formview with a Linqdata source to allow users to edit records.  When I run it, edit data and submit, it blows up and tells me "Linq datasource6  does not support the Select property when the Delete, Insert or Update operations are enabled."  I googled that warning and saw a couple of posts on this forum saying the problem is the slect statement has to be removed from the Linq data source for it to allow updates.

But if I remove the select statement then how do I show the user specific info on pageload?   plus I thought the two way databind was an advantge of the datasource control.

### Visual Studio 2008 Memory problems

My memory in task manager reaches about 900,000K  and I don't know why it does this. Definately slows everything down, especially when I rebuild my tableAdapters, takes about 30 seconds sometimes to rebuild the project.

### Problems with Forms Authentication in DD 4 site

Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

<authentication mode="Forms">
</authentication>

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!

### FormView -- Parameters and asp:Table

I've already solved this problem to my satisfaction, I just want to know WHY it works this way.

I have a FormView control bound to an ObjectDataSource.  Let's say our data source is a hypothetical table with three columns:  id, name, age.  Why is it that when I use the <asp:Table> element inside of the FormView, the parameter values are not set, but when I use the standard <table> tag, it works fine?

This seems like a .NET problem to me.  I expect the <asp:Table> element to work in the same way as <table> because they are, for all intents and purposes, the same thing.  Am I missing something?

### DropDownList within FormView Error

I have a FormView which works find and I have added a new DropDownList within the form which references another table to which I need to select a value,

I have added the dropdownlist2 and setup a new connection string to this, when I run the page I get this error:

## Could not find control 'DropDownList2' in ControlParameter 'CurrencyID'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Could not find control 'DropDownList2' in ControlParameter 'CurrencyID'.

any help would be greatly

### Problems posting to a package

Hey Y'all

I'm currently creating a program that accesses a mysql package to add data to a few tables.  I'm currently getting an error that says  "

## ORA-01403: no data foundORA-06512: at "JESSE.PKG_WORKPLAN", line 42ORA-06512: at "JESSE.PKG_WORKPLAN", line 177ORA-06512: at line 1

"

These lines are

42: INSERT INTO WP_PROJECTS_USERS (PROJECT_USERS_ID, FIELD_UNIT_ID, PROJECT_ID, USER_ID, START_DATE, DESCRIPTION)

Checking these variables in my asp.net page they are all receiving parameters.

Is there a  way to see what the database is actually receiving from the asp.net page?

Or is there another thing to be looking at?

Thanks!

### URL Routing and Existing HttpHandler problems

Hello everyone,

I have a problem:

I am currently using 2 features:

1. HttpHandler

Registering the path="res.aspx" verb="*"

2. URL Routing:

Registering with this pattern: "Company/Edit/{*companyId}","~/CompanyEdit.aspx"

In my CompanyEdit.aspx page, I used httphandler res.aspx to generate some images at client.

• res.aspx?img=1
• res.aspx?img=3

Now the problem is here, the page is load success with companyId = "12345", but when the images was loaded at client, it loaded the CompanyEdit.aspx again and show error with wrong id.

I have debug and find the problem that because when image's urls were generated to client with url=res.aspx?img=1, url=res.aspx?img=3, the asp.net will understand that they are Company/Edit/res.aspx?img=1, Company/Edit/res.aspx?img=3 when it maps with URL Routing pattern.

=> So the CompanyEdit.aspx was load again with wrong id (id now is "res.aspx").

So, do you have any ideas to solve this problem, or other design.

Thanks, and best regard

### ASP.NET 4 precompilation problems

Hello!

We used ASP.NET precompilation (first manually, then with VS2008 WDP) with .NET 3.5 almost (see below) successfully.

After we moved to 4.0, the precompilation no longer works properly. The precompilation process itself succeeds, and the website works, but it consumes about twice the CPU it does without any precompilation. We use non-updatable precompilation (so webpages get compiled completely).

Our internal profiling tells us that most of the threads spend their time within variations of the following stack:

...

System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultFromCacheInternal(System.Web.VirtualPath virtualPath, bool ensureIsUpToDate) + 0xa2 bytes
System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0x5b bytes
System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(System.Web.HttpContext context, System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0xcb bytes

### Problems converting VS 2003 project to VS 2008

Hi!

I'm having problems converting a VS 2003 project to VS 2008 (tried 2005 as well, same problem). There are several problems;
a) I don't have VS 2003 installed.
b) The project is a web service, however I'm not sure what type of VS project it was created as.
c) The general knowledge about the project setup is..slim.

I get a error message using the conversion wizard, however, I'm not familiar with the tool and I cannot quite find any good information on Google for it, so I am left with a error message I do not understand.

Conversion Issues - myProject.csproj:
Unable to open the Web site 'C:\local\path\to\project\myProject.csproj'. The Web site 'C:\local\path\to\project\myProject.csproj' does not exist.

The web service is not intended to run on the dev machine, it is copied to a test or a prod server. However, I do not know how this was done previously. I'm thinking that in order to convert, it has to access the server on which it should run (which is set somehow in a config maybe). But that doesn't actually make any sence..

If anyone could shed light on this, I would really appreciate it.

Thank you.

I am trying to have the selected item in the menu be noticeable different than the other items.  I am able to change the border as in the samples, but nothing else. I would like the selected font color to change as well as the background image / color.  Here is a sample page and style sheet.  Any help is greatly appreciated.
