When running the HttpGet action, it works fine. But when I run the HttpPost action, I recieve the error in the title.
Is it because the HttpPost doesn't have a ViewData declared?

I'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.

I am having problem with rowdatabound, want to add if conditions intact, i am using teh following two if conditions and they don't look right. i found them on google.
If e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate Then end if
If e.Row.RowState = DataControlRowState.Edit Or e.Row.RowState = 5 Then end if
With datagrids i use these and they work excellent:
If e.Item.ItemType = System.Web.UI.WebControls.ListItemType.Item OrElse e.Item.ItemType = System.Web.UI.WebControls.ListItemType.AlternatingItem Then
end if.....

I've been looking all afternoon, but the best I've been able to do when the user selects a row is to get at the item with each field in Text format.I would like, ideally, to be able to get at the row in its original MyDataType that I bound. I'm using an ObjectDataSource, and the grid (a RadGrid in this case, but its much the same deal as gridview) know the type not only of the rows by also of each and every column.I'm stymied that I'm stuck in the days of error-prone referencing columns by their name. Instead of:
grid.Items[grid.selectedIndexes[0]].item["myColumnName"]
I'd much rather be doing something like
grid.Items[grid.selectedIndexes[0]].item.myColumn
But for the life of me I can't figure out if its even possible. The grid is retaining viewstate, so it still has all of the data.
Calling Index view is giving me this very very annoying error . Can anybody tell me what to do about it

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
i was looking at one example on msdn [URL], but i can't really understand it.
View 1 Repliesrefer me few article which describe the basic use of IEnumerator and IEnumerable,
View 3 RepliesI have function it will return IEnumerable as.
IEM = myclass.getdata("name");
How to read the data in IEM as it consists of many columns. I have to display the values into labels and textboxes.
I am using LINQ for data connectivity and have made class which return me the result set into presentation here is the syntax:-
public List<ClsDermaInvestigation> MthdisplayInvestigation()
{
List<ClsDermaInvestigation> lstinvst = new List<ClsDermaInvestigation>();
ISingleResult<USP_Patient_Dermatology_InvestigationResult> investresult = objderma.USP_Patient_Dermatology_Investigation(PatientID, RepDate, Hb, TLC, F);
foreach(USP_Patient_Dermatology_InvestigationResult rel in investresult)
{
ClsDermaInvestigation objinvest = new ClsDermaInvestigation();
objinvest.Albumin = Convert.ToDouble(rel.Albumin);
objinvest.ALP = rel.ALP;
objinvest.ANA = rel.ANA;
objinvest.Date = rel.date;
lstinvest.add(objinvest)}return lstinvest}
This list is returning me the result.It works fine but in 1 case am using the same list to bind my Date dropdownlist.
//aspx.cs code
List<Dermatology.ClsDermaInvestigation> objlstinvest = objinvest.MthdisplayInvestigation();
//Array s = objlstinvest.to
drpDate.DataSource = s;
drpDate.DataTextField = "Repdate";
drpDate.DataValueField = "Repdate";
drpDate.DataBind();
But it throws an error that list does not conatin a property with "Repdate";. How can i bind this list with dropdownlist?? Can i convert it into some type so that i would be able to bind it??

I'm trying to update values I have stored in an IEnumerable using UpdateModel, but it isn't reflecting the changes when I step over it in Debug.I also tried upating it using a foreach loop and updating the values in each object T within the IEnumerable<T>. The values are changed at the object level, but it seems that the value of the object in the IEnumerable isn't being changed.I was looking at IEnumerable<T> and didn't see a way to update it... I'm thinking that I might have to assign the updates to some other data structure, then convert it to an IEnumerable or something before I try to save my repository

I have IEnumerable object with value1 and value2. value2 is an array and value1 is string. I want to databind this object to Listview like that. So both value1 and value2[0] (always first item in array) could be accessed via <%# Eval("value1") %> and <%# Eval("value2") %> .
How to write expression to handle both items ?
ListViewItems.DataSource = f.Items.Select(t => t.value1, t.value2[0]);
ListViewItems.DataBind();
I have an IEnumerable< T> which is declared on the page like this:IEnumerable< Person> person;When the page postsback, the person list is null. How can I retain the values of person list without declaring it as static? Sr. devs in my company say that you should not declare the list as static.

I'm binding my object data source to a method that returns a list of ints (List<int>).
The object data source is being used by a DataList.
<asp:ObjectDataSource ID="objectDataSourceYears" runat="server" EnableCaching="true" CacheDuration="Infinite"
SelectMethod="GetYearsUnderArticles"
TypeName="Project.DAL.Services.UmbracoService"></asp:ObjectDataSource>
My question is:
How do i display the values of the ints. Normally, I would use DataBinder.Eval(Container.DataItem, "FieldName"), but what in this case, since the object itself is the value?
i'm using MVC 2, RC, and i have a controller method:

and i have an <input type="file"../> in my form. during post, however, the files parameter is null.
My controller has a member that returns a JsonResult object, it is coded as per below. The problem is that Json(users) only returns the data from IEnumerable (MembershipUserEx objects) and I also want the data from the public Properties of MembershipUserExCollection as well. Is there a way to do this? I guess I am looking for the Json object to look something like this pseudo object:
