Forms Data Controls :: Create A Customized WebControl.QueryStringParameter?
Jan 28, 2011
[Code]....
My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.

Let's say the current webpage name is ABC.aspx and I want to make two different webpages based on this page; ABC.aspx?Mode="A" and ABC.aspx?Mode="B" (By using querystringparameter). When the user opens ABC.aspx?Mode="A" page, I want to show below gridview but when the user opens ABC.aspx?Mode="B" page, I want to show below gridview except "Gender" column.

I've created a very simple website with two roles, "administrator" and "employees". I've also added users using asp.net configuration wizard for both. My concern, however, is that going ahead it will not possible to use the wizard to add new roles, assign them or alter them once the site is online. I won't be the administrator and so I need to find a way for the administrator to add new roles and assign them to users from a remote connection. Where can I find some information on creating such forms?

I have to create a customized Next/ Previos solution, the DataPager is not flexible enough for what I want. This is what I have so far.
1. A user does a search and 100 records are returned, I have 25 records per page and so get 4 page numbers -- this is already done on search.aspx
2. The user clicks their choice (let's say its 'Post 10') and is taken to that record on details.aspx -- pretty standard stuff.
What I now need is a Next /Previous links on the details page -- so if the user clicked Post 10, on the details page will be two links, Next linking to Post 11 and Previous linking to Post 09. (i'll actually be using the post title as the text in the links not simply Next/Previous) I'm unsure about how I should begin to struture this, should I be looking at creating Temp Tables in Sql Server and step through the records or can I access the dataset from the search page and step through that?

I have an application as in the following,
[Code]....
The application works, but I would like to have 10 results per page. How easily can this be done? I don't want to use data view or grid view like most of the examples talk about, I would like to do this in the fashion that looks like what I have now, only not so many entries in a whole page.

I'm trying display data from a sqldatasource but I need to customize fonts, sizes and layouts. What would be the best way to do this. There's not much data only 8 rows and 3 cloums.
It's for a display screen that will show workers how much product they have produced.
I was looking at binding the data to lables and laying out the lables in a table but that process looks intense and streching my knowledge.

I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.

I'm gonna outline the application roughly: it's a tool, where people can upload a CSV-file, which contains their data for some crazy water-plant-biology-stuff. ;) The job of the application is (besides others) to validate their entered species. So far no problem, I've got my string-array with the correct species abbrevations, and i can parse the species names from the user-edited CSV-file.Whenever a species is found, that is not part of the reference-array its being sent to a GridView as a new row. All of the above works fine - if anything isn't explained well, just ask.
Now, what I want to do is to give the user a simple edit-function: beside the WRONG species name, it would be terrific, if there was some sort of drop-down-list, filled with the correct species names (which are stored as a string-array in my .cs-file!). The user looks at his wrong species, then just has to select the correct name from the drop-down-list, either updates row for row, or even better: edit every row, and update once at the end. Is this possible? I remember that it's quite easy to fill template-fields with data through SQL-connections etc, but is there a more simple way to do it? As said, I've got a fine string-array in my .cs-file behind the aspx-page.Haven't found any code for this. Are template-fields in the Gridview the right way?
Which might be a solution for the updating-problem: I keep storing the wrong names in the rows, and just add another column next to the species name, where this drop-down-list should appear. Then i add a button, which, when clicked, gets the old value & the new selected value for each row, and updates the data. Should work? So the problem remains: how do I add a template-field with many (<500) items in the .cs-file to a GridView-Column?

I just like to know how can i create my own authentication(calling the ASP .net membership, role) page with the same function as the LOGIN Control. Your wondering, why not use the Login control instead. I have my own design and i don't know how to pattern my design to the built in Login Control. I tried editing the login template, but it's pretty hard to pattern it to my design.
This is my design
Basically what would like to know how the Login Control calls for the authentication, and when authenticated, it will pass the user(full name) to my LoginView Control without any coding. Or is it possible that I remove default login button in the LOGIN Control then create my own button and trigger the authentication or validation? But if you have other suggestion that can follow my design and call the authentication, i would be happy to know.

i have defined a dropdown list in the controller
[Code]....
then i can show this dropdownlist in my "about" view <%=Html.DropDownList("a") %>.
BUT, now i want to define this dropdown list at my back end. what i want to do is to create a new "Helper".cs file in my project, and create a function within it. so every time if i want to show this dropdown list, i can just simply call this function instead of Add new SelectListItems one by one. is there anyone tell me how to do it?? and is it a good way to create a dropdownlist at the back end?

Using this call;
<asp:AccessDataSource id="AccessDataSource2" runat="server" DataFile="_database/92592_Web.mdb" SelectCommand="SELECT *, (SELECT MAX(ID) as Max_ID
FROM myMovies) FROM [myMovies] WHERE ([ID] = ?)">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="1" Name="ID" QueryStringField="ID" Type="Int32" />
</SelectParameters>
</asp:AccessDataSource>
How can I use "Max_ID" as my DefaultValue? So that basically if the page gets passed without a parameter, the SQL will use the Max(ID) as a default. Can I use Max_ID as a DefaultValue?
I'm an old .asp developer still on the learning curve of .NET so some of this stuff is a little daunting. In .asp doing something like this was pretty easy...

I have what is probably a basic question but I do not understand if/why there is a difference. I have a simple asp.net page with a staticly created DropDownList and Panel control. The user can select one of three options if the drop down (Employee, Company, Address) which should load the respective custom UserControl into the panel below. By default, I have the Employee control selected in the drop down and it should be displayed on the intial Page Load (!Page.IsPostBack).
If I do the following it performs the desired behavior on the intial load:
[Code]....
If I try the following, the User Control does not appear on the initial page load:
[Code]....
I noticed if I do it with a textbox instead of a UserControl, it works however:
[Code]....
I assume there is some sort of behavioral difference in the way the loading is done between a UserControl and WebControl.

I would like to be able to select a few rows from my database and display them on one page that I can share with other people. Therefore I need to generate a unique link that only displays the data I have chosen. It seems that using querystrings in this circumstance would create rather a long link, is there an alternative way?

I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater.I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs

For test purposes I have created a simple button control that extends CompositeControl. I am able to place it on the page with a <asp:Content... and the Click event Bubbles without problem from the Control.
Now, here is the problem I am facing Due to design requirement I need to read the assembly and the classname from a table and dynamically create the control and add it to the <asp:Content. And when I do that the click event will not fire! Where am I going wrong.
Here is the code in the ButtonControl.cs
namespace Reports.Web.ServerControls {
[DefaultProperty("Text")]
[ToolboxData("<{0}:ButtonControl runat=server></{0}:ButtonControl>")]
public class ButtonControl : CompositeControl {
protected override void CreateChildControls() {
Button btn = new Button();
