I have around 5 SQL queries that are returning datasets to my VB.NET application, the queries could be any number not just 5. I have a listview already on the page and all the queries will return the same exact data types (just different numbers). How can I create a listview in the code behind for each one? Or what would be my other options to load up all the results

View 1 RepliesI suddenly met a problem with nested ListViews with custom DataSources and DataPagers per each inner item.The original task looks like this. But for the independence from the data sources, I have made an essential example:
Markup:
[Code]....
Code-behind:
[Code]....
Well, the result is discouraging! The DataPagers don't work as appropriate:Try to go to the second group of pages (ex, page #6) manually, and then click on page #7 at the same Pager. You will accidentally appear at page #3!While at the same #6 page, click on page #10. Nothing will happen!Next/Last buttons not work at all!Previous button acts the same as First button!What could be the reason of such a strange DataPagers behavior?
Or, is there the better way to create nested ListViews each with it's own paging?
Could someone please point me to a tutorial that explains how to add new records in the ListViews EmptyDataTemplate
View 1 RepliesWould it be wise to use DataLoad options (to reduce memory consumption) when I have the following tables:
Main table Generic Entity
Address and company are two different tables that both relate to Generic Entity (they contain the FK GenericEntityID) but do not relate to each other
My Code looks like this:
Public List<GetEntityListResult> GetEntityList()
{
using (EntityDataContext EntityDC = new EntityDataContext(Settings.ConnectionString))
{
EntityDC.DeferredLoadingEnabled = false;
[Code]....
If you notice in the above code, the return type is a generated type by the dbml designer (since I am using a stored proc), and it is irrelevant to Company, or Address or GenericEntity. Would it make a differance to use immediate loading with DataLoad options in my example?
I am upgrading a website project from asp.net 3.5 to 4.0. I went through the upgrade wizard and site compiled and built fine. But immediately I have encountetred a problem.I have 3 nested ListViews all using the ItemCommand event. Under 4.0 once the ItemCommand event has fired on the inner ListView it then bubbles up and fires on the parent and finally the grandparent.This is a change in behaviour from 3.5 where only the inner ListView event fires. While I can code round this I am worried about these subtly changes between the two versions.

View 7 RepliesI want to display 2 levels of listview, where outer listview has a datapager with 1 inner listview per page. The code is:

I have a .net page in which i have a search button which populates the data in gridview. On Headder row of gridview i have a filter image button and when user clicks on it i need to have a div tag opened as popup and in which i have to load the data of first column data of grid view as list of checkboxs and when user clicks one by one the parent gridview need to be shortened out (reduce) basing on selected/checked item in div tag. Since the check box controls are added dynamically it need to happen in Page_PreInit, so what i am trying to do is on the search i am trying to post back the page which goes to the Page_PreInit and tries to create all these check boxes dynamically.

Well I'm not familiar with SP's yet, and I can't find a single example of what I want to do. basically I want to retrieve the town & county where the customers id are equal (note there will only ever be 1 result)
I can't figure out how to address the results to be stored within the output variables.
In my web application, i am using a RaiseCallbackEvent which gets fired on form change(to give AutoSave functionality).The problem is, if i have Requied field for 2 or more fields, on firing an event, required filed validation is asked & on entering values, RaiseCallbackEvent fires as there is form change.In this case the last postback event is also getting fired along with RaiseCallbackEvent which is creating undesireable results. Is there any way to stop this? ...
View 2 RepliesI really need some help here. I am brand new to using Visual Studio, but need to create a web page in which you must pay to register and view a Members Only page. I have followed a lot of instructions in these forums, but seem to have hit a wall.
First off, I am not able to use the ASP.NET Configuration under the Website tab. I have already created a New Web Site, selecting Visual C#, then the first option for ASP.NET Web Site. I chose File System for Web Location, etc. Long story short, I have made an ASP.NET Web Site with Basic User Login. The Login functionality is absolutely fine, I am able to view the site locally, register, and log in no problem. However, when I try to choose ASP.NET Configuration under the Website tab, nothing happens. From what I gather, I need to use the ASP.NET Configuration in order to configure membership permissions, and therefore
need to open this part of the program. In the long run, I would like to make it so that User Logins are sent via e-mail to people who have paid me and that wish to use my site, which brings me to my foreboding second problem.
I eventually need to find a web hosting service that will allow me to do all the things I have described. I was going to go with GoDaddy.com, but after doing a bit of research I realized it may not be the best option for what I am trying to do. However, through research, I have realized that VS 2010 is the best program to use for what I'm doing, but I'm in a bind because of inexperience, thus writing this question in this forum.
Any help making this web site would be greatly appreciated, I am definitely in way over my head. I have worked with computers for the last 10 years, so my inexperience is mainly with ASP programming.
Just to let you know, I have VS 2010, Visual SourceSafe, and SQL Server Express installed on this fully capable machine. What I am really looking for is someone to guide me through the process of creating this website, either through pointing me in the right direction or explaining in detail all the next steps that I must take.
I have tried various techniques that some seemed to have outlined and so far none of them have worked. I have a situation where the Page_Load() needs to build a set of <input id=<dynamic name'>> that are build dynamically inside a <ul>. The form gets created fine but when I click the button and look at the results returned to the server I cannot seem to find the input values. Is there a defined way of accomplishing this?

View 1 RepliesI've been trying to figure this one out for hours now. I'm trying to figure out why IE8 insists on displaying my gridview differently than IE7 and other browsers. First of all, width is set to 100%. In IE7, the gridview uses up the entire space of the container it's in (like it should). In IE8, the gridview only takes up the space that is required by its content
View 3 RepliesI need to create a gridview to show in each row, some columns from the SQL Database, and in other columns I want to have text fields, buttons and DropDownLists!
This GridView is to display the users of the web application.
First columns are name, email, and other stuff that can be easly queried to the SQL database.
Then, I need to have a column with one text field, and some buttons, in the text field the AdminUser should be able to insert some text and then click in a button to change the email/pass from the user represented in that line.
The other field I need, is a DropDownList that shows by default the Role of the user of the row, but we can choose another role and apply it, with a button in the same cell!
If I create a code-Behind query and populate the GridView, I don't know how to insert textbox's, button's, DropDownList's
If I create the GridView with the wizard, I can had TemplateFields, but I don't know how to associate the query with the BoundFiels where should be the name/email of the users.
Other problem, is that, even If I get to construct my GridView with sucess, How can I reference the row? So I can apply the changes?

View 4 RepliesI have data display in a gridview base on a dropdownlist. Basically, base on the downlist selection my gridview will be populated with the corresponding data. I have addresses and emails in the list. Where I am stuck and not sure how to do is export the emails to outlook for a mailmerge. For example, when the user clicks on button to send the emails in Outlook. The emails should be the ones that are display in the gridview. For the MS Word is to export the address to populate the the labels so the user can print out labels. Another button to send the address for the labels

I have two databases. When I am using MS Visual Web Developer, I can drag the table onto the webpage and it gives me check boxes to Insert, Update, Delete,...When I do the exact thing using the other database, it only has check boxes forpaging, sorting and selection. What is the difference? I seem to have all teh same permissions in both databases.
View 2 RepliesI have a page that is using the value from a textbox on a previous page to populate a formview. When I generate the Insert, Update and Delete Statements in Web Developer the edit brings up a blank page and the insert and delete don't work. It works if I just create the formview on a page and hardcode the value in the select statement then the Edit/Delete and Insert works.
