I have a FormView component, that includes an EditItemTemplate. From my code behind, i would like to access some of the components that are children from this EditItemTemplate. I tried with FindComponent() but it doesnt seems to work.
View 2 RepliesI have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)
What I want is to Disable the button, if my boolean is 1 (true).
First I tried to convert my boolean value to text:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>
But got an error:
CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
ID="lblIsPaid"
runat="server"
Text='<%#
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
And my code changed to:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>
But got this error:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.

So I wonder, is it possible to change the "Enabled" property based on by boolean value?

How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

View 3 RepliesI have a one admin to many clients scenario. The admin asks questions and the clients are expected to respond with a Yes/No. The communication happens real-time and time to live for one question is say about 2 minutes. So, after 2 minutes, the admin refreshes the question and new question is put up. I am working with ASP.NET. Before getting started on code, I was wondering if there are any components available that can be used to work with something like this?
View 2 RepliesI am tasked with re-architecture an existing ASP.Net 2.0 Web Site. The current solution has 3 projects; Web UI, Business layer project and Data layer project. The Data layer uses some sort of SQL helper class and stored procedures to return DataTable. The Business layer sort of passes the DataTable along, I don't see much business logic. The UI web site is heavy on DataGrids. While brainstorming, my thoughts are; I want to obviously keep the layered design and use the separation of code by using 3 projects in the solution.
The part that I am most confused about is the Data Layer. What should I use for this part, Entity Framework, or create my own Classes that represent my database or logical objects? Speed of development is also an issue, it has to be down fairly quickly and be flexible or decoupled for enhancements. I tried going the MVC route but the learning curve is too steep for the developers at this time. So, it has to be Web Forms. I am leaning on using Enterprise Library for Data access, logging, caching and Exception handling.
I'm trying to create reusable "zones" but am having trouble figuring out how to give them all unique ids.What I'd like is to be able to create a component which can be put on an mvc page using the usercontrol syntax or using RenderAction or RenderPartial. I want to be able to update these components' content using ajax, so I need someway to reference them by id. However, there is no mechanism in MVC that wraps anything in a div or something like that.
I've learned that if I extend ViewUserControl and put the controls on the page like so:
[Code]....
This way, I can pass the previous ID and put it in ViewData, in case I need it laterThen, I can even go through all my controls on page load event in the master page and get my unique ID and write somekind of register javascript function to the page so that I can do javascript stuff if I want when the page loads.
[Code]....
Is there a more elegant way to do this? I see similar stuff from 'Areas' but never seen an example where someone has put more than one area on a page and then needed to reference them via javascript. This also seems similar to custom templates, but I'm having trouble figuring out how that would work.
I am having problems with 2 popupcontrol extenders. They are used in conjuction with a webservice to display the detail information from a database. Each extender gets information a from 2 different tables. The extenders both work fine except when they have run across a row that has the same primary key number. Here is what the code is (I removed most of the info) to hopefully make it faster to view:
<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" CssClass="ajax__myTab" Width="100%" ScrollBars="Horizontal">
<cc1:TabPanel ID="TabPanel5" runat="server" HeaderText="" Enabled="true">
<HeaderTemplate>Agent Info </HeaderTemplate>

I have gone through many articles which uses different workaround to create .net based ActiveX control. But I did not find any standard way of creating ActiveX controls in C#. Can someone share me how to create and test ActiveX control in c#. Note that I have created ActiveX components in VB6 and now looking for a way to create ActiveX control in c# which might be similar to VB6.
View 1 RepliesI'm trying to use a GridView to display a list of components in ASP.NET. I'm trying to make it editable at the same time. One of the columns is a string that should be selected out of a list when the user edits the row.
So I've tried the following:
Convert the BoundField row to an ItemTemplate Add a dropbox to the template window in the gridview
bound the selecteditem to the string
At this point, I get an error because the list items haven't been set up in the dropbox. So I guess the two things I'm wondering are:
How do I assign the items in the dropbox to a dynamically created list of options? How do I make the dropbox only appear when the row is being edited?
Ok so I've discovered the "EditItemTemplate" field in visual studio, that answers #2.
And now I've discovered that the dropbox has a datasource field which can be linked to a property in the data object, and that holds the options list.

There was a time, when ASP.NET AJAX was Atlas Alpha version. And there were some projects for update panels: Comfort ASP, FastPage (mine:)), MagicAjax, ZumiPage. Now looks like all they dead. What people now use for update panels, except Asp.Net Ajax that is loading huge amount of js not needed for update panel. I have problems with MagicAjax installing on .net4, its deleting my scripts I dont know why. So is there update panels that 100% is working on .net4 and know about jquery.
Used MagicAjax more old version - and now it works)

View 1 RepliesI need to integrate ASP.NET into an existing Flash site. The site is heavily laden with Flash and needs to communicate with a SQL Server database. I want to use ASP.NET SQLDataSource for this purpose. Given that I need to integrate the two technologies for one web page on the site, do I need to make the site fully ASP.NET with embedded Flash objects? Or, can I just add a single ASPX page to the site that contains the web.config and connection string to SQL Server?
