FormView EditMode Findcontrol issue


Hi All,

I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate) held within the FormView. The FormView's DefaultMode is set to Edit.

I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:

Dim dtNow As Date = Today()

Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate")

txtRentalDespatchDate.Text = dtNow.ToShortDateString()

but this always returns a

"Object reference not set to an instance of an object." error


I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:

Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...

If fvDespatchPart.CurrentMode = FormViewMode.Edit Th

ASP.NET 4.0: WebForm Routing (quick n dirty version)

One of the things we're adding in ASP.NET 4.0 is built-in support for using Routing together with WebForms. Now, I'm totally aware that this is possible to do already and that a number of people have posted ways of doing this with the Web Routing feature which shipped with ASP.NET 3.5 SP1. We're just adding some features to make it easier to do

IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:


CALL_ISAPI_EXTENSION DllName="C:\Windows\Microsoft.NET\Framework\v2.0.50727\\aspnet_isapi.dll"


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.




MVC2 issue - Stuck. Trying to create a cms with nested partials


I am currently trying to display multiple items on a single page. I am not sure as to how to tackle this. What I have is a database table that has all the page data in. I have this run as a PagesController and this works fine. However what I would like to do is, if say the Products page is selected via the menu, I want to pull back not only the Products page html but also get all the products, and even be able to pull them through via category. I was trying to use a partial view, but I can't get it to work. The same would be for other pages, having partial views to display the other content, ie if Gallery is selected, the page html for Gallery shows and it then can push to a partial view that pulls all the gallery images from the gallery db table and so on. 

Maybe I am tackling this the wrong way. I have the pages stored in the db to allow for a CMS system I have setup. Maybe I need to use models for all the other items(Products, Gallery, Videos and such) and use the partial for the page html?

Any help would be greatly appreciated as I am confused.

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

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.

Multiple Paramatized Threading issue


I need the funcitonality to have two methods run concurrently of each other and the parent thread (aka the method that makes these two calls) to halt until BOTH are done. After the threads are done, I need to perform logic on the returns of the method, so it is essential for both of them to be complete before the parent thread continues. I have searched the internet and tried varous attacks, and I always come up with the same result, this being the parent thread continues operation after the first thread finishes, leaving the second thread running.  Can someone show me a quick example of how I can do this. I have tried checking states of the threads, halting the threads, but I always end up with the same thing. Any help would be great. Thanks.

Word Automation Issue in Windows Server 2008 Hosting



The problem I am posting here is that I was facing nearly 2 weeks around. Any body comes with this stuff please help.

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

Thank you.

If Statement Issue



This is very strange to me. I have spent 2hrs looking into this inside out , but dont seem to get it

I have an if statement that inserts data into the database. But i check to make sure the name is not entered twice. Now when the name is already in the db, then it should insert else put out a message saying its already in the db

My code works fine except that  when its not in the db, its inserts but still puts out the message that says "Name is already in use" Not sure if am not seeing something. But thought i did bring it to the forum. Here is my code...Pretty simple

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click

        Dim objConnection As SqlConnection
        Dim objCommand As SqlCommand
        Dim strSQLQuery1 As String


        ' If there's nothing to Add for then don't search
        ' o/w build our SQL Query and execute it.
        If String.IsNullOrEmpty(txtAdd.Text) Or Leadbank.SelectedValue = "000" Then


VB webform in IronPython asp.net website


Hi, I tried to bring a previously done webform made in vb.net to an IronPython asp.net website with no luck. After seeing it didnt work, I tried to write the simplest codebehind vb.net webform to see if there was a problem with vb.net in an IronPython website and I got the following usual error "be sure that the defined class in this file matchs with the one in the attribute inherits and that it extends the right base page (page or control)" (sorry if the translation isnt the most accurate I get that message in spanish) but if I create a vb.net webform in the same website, with the sourcecode in the same file (with the vb.net code between script runat="server" tags in the same page) I get no problem. Do I have to configure something for both kind of sourcecode languages to run in such way in the same IronPython website, like configuring something in the webconfig file or is there some compatibility issue for doing that which can't be resolved?

I figured out that in some cases I can solve it by creating the app_folder and moving the vb files there, but if these files dont inherit other classes which are in the app_folder
