I just want to do a select in one SQL SERVER TABLE using LINQ to SQL. And this select statment needs to compare one SQL filed to one hashtable key value.
Dim q = From product In db.productDB _
HashVar As DictionaryEntry In MyHashTableVar, _
Where _
product.productID = HashVar.Key
"Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains operator"
In my ASP.Net application, I am using ajax accordian control on my aspx page and vb.net for code behind pages.
I have used validation summary for page validation.
1st accordian Pane contains following fields:
First Name
Last Name etc.
2nd accordian Pane contain following fields:
Address
City
Country etc.
while validating the page It displays error messages in following sequence:
Address cannot be blank
City cannot be blank
Country.....
First Name....
Last Name....
But I want to display error messages in following order:
First Name cannot be blank
Last Name....
Address cannot be blank
City cannot be blank
Country.....
I tried to resolve it by giving tabIndex to textboxes and RequiredFieldValidator, but sequence doesn't change I created RequiredFieldValidator again in sequence, but it doesn't affect.
want to know if linq to sql auto updated the id column of a class (table row object) after SubmitChanges is called inserting a new row to that table, that would be fantastic, would anyone be able to confirm this?

I created a website using VS2010. When I run the website using built-in web server, everything works fine. The website recognizes javascript and aurigma uploader. When I publish the website to local folder and tried to access using IIS 5.1 on local pc,
the java scipt files did not work. I was getting yellow triangle sign at the bottom of the page indicating the object is expected. I tried to look online but i could not find any answer. I have included jquery and javascript file in the header section of master
There is a hyperlink to a local file...for instance....C:/text.txt. This is not possible, because ASP.net does not allow links to local files. But, links to files on network drives such as W:/test.txt are working ok. how does the browser know which drive letter is local,and which is networked? How does it know that C: is local or D: is local etc, and that W: is a network drive?
View 1 RepliesHow do I get the smtp server address for the local machine? I want to my email address on a windows form and have the user send me an email and I need to be able to get their smtp server address programatically to do this. I tried this:

It caused an exception.
I have a set of text boxes and html editors in my form. I am not able to set the proper tab index. The tab index moves from the first text box and skips all the controls in between and reaches the last html editor and the third tab takes me to the address bar and then it moves randomly all over the controls. I now want to remove the tab index for all controls and then assign the index in a sequence programatically.

I want to store it in a database as a column.
I'm looking for a good tutorial/article that explains the exact sequence of events that takes place when a page is created. I can never remember the order. I think it's something like the parent controls Init event is called, then the child controls Init event is called, in order of the placement on the page. Also, when the control events are called, what order are they called in? For example, if a button event is raised, does this event get called before a DataList_ItemDataBound event is called if the DataList.DataBind is in the Page_Load event? So, does anyone want to try to explain or direct me to a nice article that explains all this?

View 1 RepliesI like this idea when I don't have to use slow expression compilation to be strongly typed. But the current implementation is too aggresive for me - I hate virtualization my action methods.My question is: Are you planning some (branch) implementation that will not require action method virtualization? I think that most of code could be shared in both branches...

I have a modal popup where the 1st control is a dropdownlist, then 2 invisible textboxes and then one visible text box(txt1). All of these have required field validators attached with ajax callout extender.
Based on the dropdown value, the invisible textboxes get visible and the corresponding required field validator controls get enabled.
Now problem is, if i dont enter anything and click on submit, instead of showing error message for the 1st control i.e. the drop down, it is showing message for the visible textbox(txt1).
what i am supposed to do, to display the error messages accordiing to the tab index of the controls?
What is the escape sequence for &-sign in string literals in web.config?
View 2 RepliesI find myself doing a ton of jquery these days so I started to abstract out some of the common things I do into snippets. I look forward to sharing these with the community, but i'm running into an issue right now. The literals in snippets are defined by adding dollar signs ($) around the name of the literal to delimite where the value you would like to provide will go. This is difficult because jQuery uses the dollar sign notation in order to use a lot of it's functionality. Does anyone know the escape sequence for snippets so I am able to use the dollar sign, and have my snippets still function?

View 4 RepliesWhen using a databound control the Bind() method does some magic to first extract the current value from the datasource and then pass an update back to the datasouce when an update is performed.
Now I have created a custom datasource and am supplying my own custom data which all works fine. For read only the following code works a treat. As you can see I am accessing both a named index into the collection and a property.
Now when using Bind() I cannot find a way to accomplish this. Bind() would appear to look for either an object property or a database row column (not sure how it does this) and I cannot find a way to change this.
It shouldn't be that difficult because the hard part is obtaining the data, which my code below can already do. The changes are passed back as a dictionary which should be simple. But I need a way to write my own bind method and I haven't managed to find out how.
Code:
Surname : <asp:TextBox ID="TextBox2" Text='<%#((MyCustomDataRow)Container.DataItem)["Surname"].EditDataString%>' runat="server" />
I'm fairly new to dependency injection but it seems like a proper DI implementation will be fairly complex.
For example, DI requires a centralized class that manages the configuration and resolves the dependencies at runtime.
DI is also based on the concept of using interfaces. For example, a SpecialLogger should use an ILogger interface.
The centralized DI manager class will need to register types - for example, associate ILogger to SpecialLogger.
SpecialLogger will also need to implement the ILogger interface so SpecialLogger can be used through the DI ILogger interface.
Therefore, it seems like a sln using DI will need multiple projects to support DI. Here is an example for logging:
* MyCompany.MyDivision.Framework.DI.Management - this would have the DI manager where dependency types are registered and resolved at runtime
* MyCompany.MyDivision.Framework.Logging - this would have the implementation of a logging class. The main logging class would need to implement ILogger.
* MyCompany.MyDivision.Framework.DI.Interfaces - this would have the ILogger interface.
Interfaces would need to be stored in a separate class library from the DI manager because both the DI manager and SpecialLogger use the ILogger interface. Since the DI manager associates SpecialLogger to ILogger a circular reference would be encountered without a separate class library to store the ILogger interface.
I want to use Event Aggregator to allow communication between presenters on the page. I am using currently this implementation http://kentb.blogspot.com/2008/03/event-hub.html. But in asp.net I am not sure about side effects which can occur.
