View 7 RepliesI'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 using datalist to bind the generic list. On databind() command I am getting error "nable to evaluate expression because the code is optimized or a native frame is on top of the call stack.

[Code]....
I have been facing this problem for a while now, what I exactly want to do is ->
I have a 3- Tier Application. For a table (say Employee) I have following classes in my BLL and DAL
1. Employee.cs (Contains database fields as properties)
2. EmployeeKeys.cs
3. EmployeeFactory.cs (Main BLL which make call to DAL method)
4. EmployeeDAL.cs (The DAL)
Suppose I have 6 columns in Employee table.
I know that the DAL returns List<Employee> to the BLL and then the BLL in turn gives me the Employee fields.
I have no problem accesing it.
But suppose I have a dropdownlist control and wish to bind EmplyeeName and EmployeeId with the Dropdown.
Is there any way that I can implement that my DAL returns a Generic list containing only the two fields required to bind the Dropdown.
In short i want my list to return only 2 columns, not all the 6 like the List<Employee>
How do i implement this???
Do I need to create a custom List<CustomEmployeeData>, if so how can i implement it in the 3 tier application.
Basically i m looking to increase the efficiency by getting less data from database. Am i on the right track????

I've got a class that implements IListSource and returns a generic List of ListItem objects (List<ListItem>). in this list one of the ListItems has the Selected attribute set to true.On the web page I have a standard asp:dropdownlist and I set it's datasource to the getList method of my class and databind it.The problem is that the databind seems to loose the selected Item and the first item in the generic list becomes selected.
View 8 RepliesClicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.

Now i want to do search, sorting & Paging in the GridView with out Postback of the Page & with out hitting the DataBase when do Paging or searching in GridView.

The Gridview's source code:
[code]....
What i cant figure out is how to implement the sort method to the gridview when fetching data from a generic list... I have been Googling my a** of trying to solve this.
I have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))
