.net - Convert An E.item.dataitem To Type (Of T)?

Jun 13, 2011

I'm trying to do this in an item_databound event of a datagrid in asp.net

Dim EntType As EmployeeEntity = DirectCast(e.Item.DataItem, EmployeeEntity )

but I encounter the error

Cannot convert to class EmployeeEntity

The EmployeeEntity class has the same members as the items in e.Item.DataItem's DataRowView items. so how else do i cast the contents, without having to actually set each property of EemployeeEnity individually, from the e.Item.DataItem ?

Jul 7, 2010

With the ASP.NET Repeater control, I am used to being able to access my data item values in the ItemDataBound Event Handler by doing:e.item.dataitem("column_name")

However, it seems with the ListView control this is not possible. How can I access the data item values?

Asp.net - Unable To Add Text Along With <%# Container.DataItem %> In Repeater In User Control

Nov 26, 2011

I have a User Control which is dynamically placed by CodeBehind as follows:

Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control)
If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then
mainMenu.Controls.Add(myControl)
End If

As per an example from my previous question on here.

Within this Control is a repeater which calls a database to generate values.

My Repeater mark-up is as follows

<asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount">
<ItemTemplate>

[Code]....

The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p> to print to the browser like this is some text DATA_ITEM_OUTPUT

When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code.

It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text

C# - Get The Item Type From A BindingSource?

Jun 14, 2010

I would like to get the Type of item that a BindingSource is hooked up to or configured for. The BindingSource.DataSource property can be set to an object, list, or type. If it is a Type, it obviously does not have a bound item yet, but I would still like to get the Type. For a List, I need the item Type, not the list type.

I currently have a custom list type for business objects that implement an IListItemType interface, that I created to solve this problem a while back. I would now like to get this working in a more generic fashion so that it will work with any list.

I've looked through the API docs for for a good way to do this, but so far I have not had any luck. Am I missing something or is this just something I can not or should not be doing?

I have a piece of code that does an action to any collection that implements generic.IList<T>However to do this it needs to get the type <T> of the generic list.e.g. If I pass in a variable of type Generic.List(Form) then in my code I need to get the fact that the list is made of Forms. To add complexity the list may be empty (So you can't just look at Item(0).GetType)
