Forms Data Controls :: Binding LINQ Results To Gridview?
Jan 6, 2010I am trying to figure out how to bind my link results to a datasource so it can manage/update/edit/insert/delete without me having to do manual coding for all of it. Is this possible?What am I doing?I have used the LINQ to Active Directory to access our AD accounts. I need to make this a webpage frontend of basic search and managing functionality. I have it searching now and adding the results to a gridview but edit is not working now. I was looking online and I saw something about being able to bind linq results to a datasource and then using the datasource to manage all the information for me. Resources I am using:

Binding Different LINQ Datasource Using Same Variable With If Statement?
Nov 27, 2010OK So I know WHY I am having the error I am getting. I don't know HOW to fix it. Basically, if the user doesn't have a certain permission, I need to join another table. But .NET is so picky I can't just make two different queries in an IF statement and then use it outside of the if statement. I can think of some ugly work arounds for this, but I would rather not. I am fairly new to .NET I know just enough to be dangerous.
[code]....
I get the error: Unable to cast object of type
'System.Data.Linq.DataQuery1[VB$AnonymousType_111[System.Guid,System.String,System.String,System.String,System.String,System.Nullable1[System.DateTime],System.Nullable1[System.DateTime],System.Nullable1[System.Guid],System.Nullable1[System.DateTime],System.Nullable1[System.Guid],System.Nullable1[System.DateTime]]]' to type 'System.Collections.Generic.IEnumerable`1[Ten11CRMLib.Company]'.
because of this: Dim l As IEnumerable(Of Company) its not just IEnumerable of a Company, its got the source in it. I have to explicitly select source to use it in my datagrid. Can I make Dim l something that will make it stop complaining?
Forms Data Controls :: Binding DataSet And GridView, Apply Bulk Rows Edit And Update On GridView
Dec 10, 2010I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
Binding Xml Data Into Gridview Using C#?
Mar 24, 2010I have a XML file which contains a list of items/elements:
[Code]...
I can bind the data into a gridview. However, only the attributes are displayed(which is: category and ID). I need the elements to display out too (which is: Name,Description,Latitude and Longtitude).
Would anyone be kind enough to solve this problem for me?
And is it possible to populate a drop down list in using the same XML file? As in populating the category in the drop down list.
Linq - Couldn't Determine Metatable Error Binding List To Datagridview
Dec 25, 2010List<ThemeObject> themeList = (from theme in database.Themes
join image in database.DBImages on theme.imageID equals image.imageID
into resultSet
from item in resultSet
select new ThemeObject { Name = theme.Name, ImageID = item.imageID}).ToList();
dgvGridView.DataSource = themeList;
dgvGridView.DataBind();
The list object populates fine. The datagrid is setup with 2 columns. A textbox column for the "Name" which is bound to "Name" An image column which is bound to the "ImageID" field. When I execute the code I receive the following error on the DataBind() Could not determine a MetaTable. A MetaTable could not be determined for the data source '' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute. I'm not using any dynamicdataroutes as far as I can tell. Has anyone experienced this error before?
MVC :: Saving A Complex Child Object After Post (LINQ To SQL Model Binding With MVC)
Jan 6, 2011I am using ASP.Net MVC2 and LINQ to SQL. I am using DataAnnotations and model binding in conjunction with a Form/View and its working beautifully well. Loving that.. My view is an "Add new Employee" form that's adding a new "Employee" complex object. Every Employee also has a child complex object called an "Address".
I am using the bound Html helpers in the view, such as Html.TextBoxFor(model => model.NewEmployee.FirstName) for example. Working beautifully well, validating beautifully well both client and server and coming into the controller fully populated and ready to be saved! Exciting.. ModelState.IsValid returns true and I go to save the new Employee.
The Employee is created fine but the system also creates a blank/new Address record in my Addresses table even when the Address fields are blank! How can I prevent any Address from being created, in situations where I ONLY want to create a new Employee with no Address. An example is when the user supplies an existing Address, then I wish to simply set the new Employee's AddressID to that of an existing physical address (I hope that makes sense). But it could apply to any situation where you need to create a new complex object, but you don't wish for LINQ to create any of its child complex objects. I have tried setting NewEmployee.Address = null after it is received in the controller, but even after that, a blank/new Address is still created. Even if I try NewEmployee.Address = SomeExistingAddress, it does correctly link the Employee to the existing Address, but it STILL goes off and creates another redundant new/blank address record! Which is really weird..
MVC + LINQ To SQL Model Binding - Saving A Complex Child Object After Post
Jan 5, 2011I have a "Create New Employee" ASP.Net MVC form. My complex object is an Employee and an Employee has an Address, which is another Complex object. On my View/Form I collect all required values for both the Employee and the Address. I'm using the bound HTML helpers such as: Html.TextBoxFor(model => model.EmployeeAddress.StreetName)
AND
Html.TextBoxFor(model => model.NewEmployee.FirstName)
This is all working beautifully well. Model binding is working like a dream, both server side and client side validation using DataAnnotations is working beautifully well and I am nicely receiving my populated complex objects as expected in the Controller.. Now I'm trying to save.. The Employee should always be newly created, because its an "Add New Employee" form. But sometimes the Address is an existing Address and I don't want to insert another one. Rather, I just want to link the Employee to the existing AddressID of the one that already exists in the database.
So I wrote a nifty GetExistingOrCreateNewAddress(Address PostedAddress) method which works great so I end up with the correct Address to use and link to the about to be saved Employee object. This is all happening in the same DataContext, so no problems there..
BUT even when I link the about to be saved Employee object to an existing Address, on save a new/empty Address row is created in my Addresses table. Even though the newly created Employee does link correctly to the existing Address I told it to! Why is it so??? And how can I save the new Employee without LINQ automatically creating a blank Address for me. Because I'm explicitly specifying an existing Address it should be linked to instead!
[HttpPost]
public ActionResult CreateEmployee(EmployeeDetailsViewModel NewEmployeeDetails)
{
if (ModelState.IsValid)
{
EmployeeRepository ER = new EmployeeeRepository();
// Fetch or Create the appropriate Address object for what has been entered
Address ActualAddress = ER.GetExistingOrCreateNewAddress(NewEmployeeDetails.EnteredAddress);
// Link this Address to the "about to be saved" Employee
NewEmployeeDetails.Employee.Address = ActualAddress;
// Lock it in..
ER.SaveNewEmployee(NewEmployeeDetails.Employee);

Forms Data Controls :: Binding Data To An Item Template Element In Gridview?
Mar 26, 2011not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
[code]....
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.

Jun 24, 2010I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable
With TblBasket
.Columns.Add("BskPrdCd", System.Type.GetType("System.String"))
.Columns.Add("BskPrdDesc", System.Type.GetType("System.String"))

.LoadDataRow(Split("12345,Test product 1,1", ","), True)
.LoadDataRow(Split("122,Test product 2,2", ","), True)
.LoadDataRow(Split("123A,Test product 3,5", ","), True)
.LoadDataRow(Split("44,Test product 4,1", ","), True)
End With
DstBasket.Tables.Add(TblBasket)
With LfnGridView("GdvBasket")
.DataSource = DstBasket
.DataBind()

The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
