In a pluggable architecture for asp.net mvc, i need to build a form where any plug-in can add its form elements to a form through application wide events. When the form is submitted back to server, values of elements must be saved by relevant plug-in which added the form elements. how to build and save forms like that?
View 1 RepliesI am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code):
DynamicString = FunctionThatCreatesDynamicString()
' DynamicString = "[URL]
If ImageExists(DyanmicString) = StatusCode.200 Then
' Embed link in ASP.NET page
Else
' Embed not found image in ASP.NET page
End If
My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML.
I want to build link buttons dynamically, and the link is clicked run a subroutine.

Once that linkbutton is created, then i would like to concatenate that with text that i am placing in a text box.
I recently stumbled upon this thread over at StackOverflow regarding the dynamic construction of a Master Page menu based on what roles a user is a part of. The original poster proposed a solution to his own problem, but rightfully noted that it was kludgey in that it didn't scale, but also that it violated the Separation of Concerns (SoC) model of MVC.
View 23 RepliesI am building an invoice system for a client and I am having trouble with the web forms related to the INSERT new order query.Basically I want to build up the order query from the selections made and then store it all in db at the end.
I don't want to use temporary db storage because it's a wasted trip to the server, I don't want to use session state because it's not data about the user I'm storing.... Unless I'm wrong, from what I've read I think query string is my best method since the data is not sensitive, it will just be primary keys and the like.
On the first form, the user will select the customer id from a datagrid displaying all customers. The next form allows them to choose the product from a datagrid showing all products and so on.... How do I pass this information across several pages?
My hope is at the end I will be able to take all the values and insert them into the corresponding tables to make up the customer order.
I have an Employee model that has a Name and Company
I want to be able to build multiple Employees in one CREATE view. I figured I need to create an IList<Employee> and do something like:
<%= Html.TextBoxFor(m => m[0].Name) %>
<%= Html.TextBoxFor(m => m[0].Company) %>
<%= Html.TextBoxFor(m => m[1].Name) %>
<%= Html.TextBoxFor(m => m[1].Company) %>
If a user clicks on "Add another employee", I want the view to make another form for the new employee:
<%= Html.TextBoxFor(m => m[3].Name) %>
<%= Html.TextBoxFor(m => m[3].Company) %>
And continue to add form items (and increment the array index if they click on it again).
Keep in mind that I need to build the form and the list dynamically in the create view. I don't already have a populated list of Employees.
I know that it is basic questions, but I am stuck here.

I have SQLDataSource for my gridview. By default it works fine but i need to determine a few things before calling my procedure. By this i mean i need to determine a few things about the fields completed and set a flag to determine where the procedure will look.
I found a few examples online on passing parameters in code behind, but cant seem to get them to work. Here is what i tried and cant get results back. When i execute the procedure on the SQL side with the same parameter values, it works, so i know its returning results, so means my values are not being sent or im doing something really wrong. I have some of the lines commented out so the page can load and display for now.. but i need to get it working with custom parameters and flags.
Here is my SQLDataSource:

I am trying to build a repeater dynamically through the code behind. I found this code on the microsoft site:
Protected Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Repeater1.HeaderTemplate = New MyTemplate(ListItemType.Header)
Repeater1.ItemTemplate = New MyTemplate(ListItemType.Item)
Repeater1.AlternatingItemTemplate = _
New MyTemplate(ListItemType.AlternatingItem)
Repeater1.FooterTemplate = New MyTemplate(ListItemType.Footer)
Repeater1.DataSource = New String() {"one", "two", "three", "four"}
[Code]....
So this code works without throwing any exceptions, but what I would like to do is accessing the DataSource inside of Sub InstantiateIn(). I know you can access the DataSource in the front end using DataBinder.Eval and Container.DataItem, but is there a way to access the data during the InstantiateIn() Sub?
Or if there is another way to do this i'm up for trying that as well. Essentially I am trying to avoid writing asp.net code, instead I would rather write everything in vb (code-behind)
I having a dynamic build html table from jQuery and trying to attach the click event to it..How can I register that event on table and what to do with the function that looking for the table tr id and can't find it.I prefer not to write the click function as text as well with the tbl if possible, and not to write some of the table on the html body if possible - so all the table will be build from the innerHTML

I have a .NET 1 web app that is using a Oracle database, the web app has a page of table names that allows the users to select, there are 101 tables listed on the page. When the user clicks on a table name, it takes them to a page that shows user friendly column headers, the table data, etc. Is there a way to use one GridView to do this and show the user friendly column headers instead of creating 101 pages or 101 user controls and show that control based on the table passed into the page?
for example: the user clicks table 22, I want my gridview to look like this
Buyer's Name State City Zip Code Phone Number
if they click table 55 I want them to see this
Product Wholesale Price MSRP Sale Price On Sale (check box)
instead of showing the users
BuyersFullName BuyersState BuyersCity BuyersZipCode PhoneNumber, etc
and so I, I would like to use 1 gridview on one page if possible and build the grid on the "fly", We have the user friendly column headers in a table.
So my questions are:
is this possible, if so, what is the best approach in doing this
from a scalabilty level and maintenance level, would the 1 gridview be worth for all 101 (and growing tables), or would building a seperate user control for each table be better?
I have a dialogue window that contains an Accordion Control that is dynamically built. The only thing that appears on my source page is the opening and closing tags for the control. The panes and the controls that appear on the panes are all added dynamically based on records in a database.
Now here is my situation, if a certian action is performed on one of the controls then I want to save that controls data and make it no longer available for use, this was easily accomplished by having the control hide itself. An issue arises though when I have hidden all of the controls on a certain pane, the header for the pane still exists and this is not the desired result.
What I would like is to be able to dynamically remove the entire contents of the control and then re-build it. Due to the timing of the events in the page post back sequence, a simple call to the method that builds the control will not work and if an explanation is required I will provide one. Also, looping through all of the panes and the controls on each pane will not work since after the first pass through the loop the panes collection is mutated, the enum table for the control is no longer correct since the initial pane has been removed, as a result the for loop throws an error.
Can any one come up with a way that I can clear out the control, keeping only the basic empty structure, and re-build it all in a single post to the server?
I've build a linq query.But i want a random selection so its not always ID : 1,2,3,4,5,6 How can i randomize this var? I like to bind it to a repeater.//TagCloud:

I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?

I need to dynamically construct a url by appending new parameter to the current url.
I know how to do this in the long way by getting the current url and check if there is any QueryString, if no add "?" if yes add "&". Also check is the parameter is already exist. If yes change the value.
But is there any build in .NET function to do this? Like Request.QueryString.Add
