I am wondering how I am supposed to get/set/replace the ImageUrl using asp
[Code]....
Where it says GetImage, I want to get the string of the url path which is stored in a List of custom objects that gets binded to the gridview...
I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
I have the following code:
[WebMethod]
[SoapHeader("_webServiceAuth")]
public User GetUser(string username){
try
{
this._validationMethods.Validate(_webServiceAuth);
User user = new User(username);
[code]...
I want to display image with asp:label, I also want to display message in two lines in which first line with 12 pt size and second line with 11 pt.
I am using asp.net with C#.
What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....
The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.
public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.
For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.
I am having a purpose to display an image (like floor plan) and map its area dynamically for a web application in ASP.NET.
View 1 RepliesI have Create a Custom Principal and a Custom Identiy for my Web Application and upon forms authentication
1 Create a profile of type object
2 Assign it to the Principal profile
3 assign the principal to the Http.Current.User (this now has the complete profile information )
As i understand upon redirection the principal is recreated and i loose the information i had stored in the profile.
I there a way to persist the profile information ?
I though can achieve persisting some information using FormsAuthenticationTicket in userData but that wouldent solve my purpose ..
I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below:

public override bool ChangePassword(string username, string oldPassword, string newPassword)
{
if (!ValidateUser(username, oldPassword))
return false;
ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true);
OnValidatingPassword(args);
if (args.Cancel)
{
if (args.FailureInformation != null)
{
throw args.FailureInformation;
}
else
{
throw new Exception("Change password canceled due to new password validation failure.");
}
}
SqlParameter[] p = new SqlParameter[3];
p[0] = new SqlParameter("@applicationName", applicationName);
p[1] = new SqlParameter("@username", username);
p[2] = new SqlParameter("@password", EncodePassword(newPassword));
bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);**
return retval;
} //ChangePassword
public override void Initialize(string name, NameValueCollection config)
{
if (config == null)
{
throw new ArgumentNullException("config");
}
......
ConnectionStringSettings ConnectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]];
if ((ConnectionStringSettings == null) || (ConnectionStringSettings.ConnectionString.Trim() == String.Empty))
{
throw new ProviderException("Connection string cannot be blank.");
}
connectionString = ConnectionStringSettings.ConnectionString;
**dbConn = new DBConnect(connectionString);
dbConn.ConnectToDB();**
......
} //Initialize
......
} // SGIMembershipProvider
I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider.

View 1 RepliesModerators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.

View 6 RepliesI'm teaching myself ASP.NET MVC, and am trying to figure out where best to put a function which takes in an Models.Address instance and returns an IHtmlString instance which reads something like:
Line 1<br />
Line 2<br />
City, State
The string could be used in many places throughout my project, so I don't want to write it in one view and have to keep copy-pasting it or attaching that view: By the same logic attaching it to ViewData seems like a bad idea. However, the HtmlEncode method requires an instance of server, which means I can't add the function to the model class either.
Is there a right place to put this - some sort of shared view? (does this belong in the master?) Or am I going about this all wrong?
My current best idea is to create a ViewModel with the method public IHtmlString FormatAddress(Address address, HttpServerUtility server), but I don't know if that's the ASP.NET MVC way to do it.
If I have the following ASP.NET code (it's not complete - obviously there's a lot missing, but none of it matters):
<asp:GridView>
<Columns>
<asp:TemplateField>
<ItemTemplate>
My Label: <asp:Label />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
My Text Box: <asp:TextBox />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And if I have something like this in the CodeBehind:
Private MyListOfObjects As List(Of MyObject)
...
Public Class MyObject
Public MyTextBoxString as String
Public MyLabelString as String
End Class
How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.
I've implemented a custom ASP.net membership provider to deal with forms authentication. The custom provider uses a custom User object for authentication and authorization. I was wondering If I can pass this object to each WCF call without adding it to the parameters list?

I'd like to add some custom instance properties to an ASP.Net User object. for example, I'd like to log every user's login and have something like: User.LoginTimes or calculate the User Profile's Completion percentage and be able to access it like: User.ProfileInfoPercentage, etc.
Now What I'd like to know is what would be the best approach to do this?
Forget about user instances? (e.g. define a database table with userid and ProfilePercentage info and retrieve data from profile like: DB.GetProfilePercentage(Context.Current.User.UserID) )
Override the ASP.Net User class and add my own functionalities.
Use Extension methods for the user class.
I'm kinda new to web services and want to make sure I am doing things correctly.
I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)
I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?
What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.
I tried this dll
[URL]
But the output XML doesn't seem to include the sub object.
