Forms Data Controls :: Adding A Dropdown List As A Filter Option After Listview Is Displayed

Aug 4, 2010

I have a listview that is displaying records currently based on a dropdown.. works great.. now, within those results returned, i would like to filter down some more.. How can i add a dropdownlist to the page that is populated with data from the listview(only 1 field would be used to create the list ) and if you chose to filter by that drop down, then the listview is revised to display only records with the selected value.

Example..

Currently you pick from a drop down.. Report#1, Report#2 or Report#3 Say report#1 returns 100 records.. and the field im going to be filtering on is my "Vendor" field.. so once my listview displays my results, a dropdownlist is populated with all the vendors that were returned with the query.. could just be a few..

Now you are sitting there paging thru all the records.. and realize you really just need to see out of the 100 records, records that belong to Vendor#3, so you pick #3 from the drop downlist and the procedure is called again now filtering on that vendor..

Web Forms :: Can't Select Dropdown List Option If There Is Only One Option Returned

Jun 29, 2010

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.

I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

C# - Overriding SQLMembershipProvider / Adding Few Extra Methods To Deal With The Roles By Using LINQ?

May 27, 2010

Is there built in methods into .net framework to do the following:

Get role GUID from user name/user GUID
Get role name from role GUID

So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this?

I have the following methods that I store in the ASPUtilities class:

getRoleGUID(guid userGuid) { LINQ joins }

getRoleGuid(string userName) { LINQ joins }

getRoleName(guid roleGuid) { LINQ joins }

EDIT:

I have just looked into extending SQLMembershipProvider examples.

Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?

How To Specify The Selected Option To A Dropdown List MVC

Apr 14, 2010

I have a list of options (IEnumerable< SelectListItem >) in my model that I want to use in multiple dropdowns in my view. But each of these dropdowns could have a different selected option.

Is there an easy way to simply specfiy which should be selected if using the Html.DropDownList helper?

At this point, the only way I can see is to generate the html myself and loop through the list of options like so:

Option - Retain Dropdown Value Page Posting Back To Itself C#?

Jun 15, 2010

I have an aspx page that has...

if (!IsPostBack)
{
PopulateBrand();

in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value.

The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it.

How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked?

DataSource Controls :: While Adding LINQ To SQL Class - Empty Use Option

Feb 4, 2010

I am new to LINQ but not >net. I do understand SQLDataSource, etc. I was just told by a coworker not to use a LINQ to SQL Class for my new project (Bank.dbml). I was told to use instead the ADO.Net Entity Data Model (bank.edmx).

BankModel.edmxBank.dbml

When only using ADO.Net Entity Data Model I try to associate a GridView with a new LinqDataSource I get no options. When I add a LINQ to SQL Class I get the option to use it but it is empty. Is this because all my LINQ classes are mapped in the ADO.Net Entity Data Model (bank.edmx)? Can someone tell me (or point me to) what the differences are in these two?
