I am using membership functions like
Roles.GetAllRoles()
or
Membership.FindUsersByName();
I want to assign the result of these fucntions to a dataset or datatable and not directly to a GridView.
Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.
View 1 RepliesNewb question: what is the standard practice for assigning roles to newly signed-on members. Is it usually manual or is there a way of automatically assigning roles. Being completely new to this, I am confronted by the issue of my site having three different roles that new members could fall into, but am unsure about how to assign each a role. I can't imagine having to go through the process manually if I have thousands of members.
View 6 RepliesI have a dataset which consists of a set of records. I have put this dataset records in a viewstate so that I can access it from a different method on the same page.
ds = TelephoneDtl.GetTelephoneData();
ViewState["CurrentPos"] = ds.Tables[2];
I now want this view state values to be assigned to a datatable. Something like this:
datatable dt = ViewState["CurrentPos"];
But doing this gives me a typecast error
I have a code something like this :
MyLinqDBDatacontext db = new MyLinqDBDatacontext();
var taskname= db.my_stored_proc_get_taskName(int taskId);

this works fine

I need a functionality something like :
Dataset ds= new Dataset();

how to copy data from datatable to table in dataset i ry this but its readonly property

I have a gridview which I am using to display a dataset result. The problem is I am using paging in it. But when I click on the page # it says that I haven't handled the event. Do I need to rebind the dataset?
View 1 RepliesI have DataReader that holds the results from a stored procedure caal. The results consist of two fields ...
UserID
UserName
Normally I bind these results to an ASP.NET dropdownlist control ...
ddlUserList.DataSource = rdr // rdr is the DataReader
ddlUserList.DataTextField = "UserName"
ddlUserList.DataValueField = "UserID"
ddlUserList.DataBind()
However I am now trying to accomplish the same thing using jQuery AJAX. What I am stuck on is how to manually convert the dataset held in the DataReader to JSON. How are multiples values separated? Does this look correct?
{{"UserID":1, "UserName":"Bob"}, {"UserID":2, "UserName":"Sally"},{"UserID":3, "UserName":"Fred"}}
I realize there are libraries out there such as JSON.NET to handle the serialization but I am in the learning stage now and want to make sure I understand everything from the bottom up.
If I need to fetch one whole column from Table1 in the DB, should I fetch it using datatable or dataset? I can do both ways. I mean ok I should use Datatable. Why is that? What would happen if I use Dataset? ok that's what I wanted to know. So there's memory issue. I mean whatever I use be it Datatable or Dataset, both will be fetching only ONE column frommy table in DB. How is Dateset's gonna use more memory then?

Anyway, what i am trying to do is display job vacancies by the result of a DropDownList value. Now each job name has a description. The problem i am having is i need to display the results in this logic:
Job nameJob descriptionJob location. But what is happening is the job description (body) is repeating the more vacancies there are. This is the page:
http://kidsunlimited.co.uk/vacancies_test_two.aspx
If you select Deputy Nursery Manager from the DropDown and hit the Search button you will see the results. After listing the first two locations the description is repeated and then the 3rd location is shown after this. This is my code:

View 4 Repliesprotected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
Roles.AddUserToRole((sender as CreateUserWizard).UserName, "Customers");
}
CreateUserWizard is creating dupicate user while assigning Role.How can we assign Role without duplicating user record? I've observed ApplicationID for assigning Role is Differenent than Creating New User, so when ever Role assigning comes in, it creates same user again with new UserID. Is it related to Web.Config in some way? As when I try to create user from "VisualStudio/Website/ASP.net Configuration"

View 1 RepliesI'm returning one table. My understanding is that a DataSet can be made of more than one DataTable. I also understand that I can use either of these to return my one table.
Is it better to use the DataTable when I have one table to return instead of a DataSet? Is there any advantage of not using the DataSet in a situation like this? Is there a disadvantage to using the DataSet when only one table is being returned? Does this even matter?
