I have a ListView which is filled by generic list of type MyClass. I can easily bind data from this list into ListView. But I have problems with reading data in opposite direction. This is my class:

Finally I bind data to ListView this way:

My ListView template:

How can I read data from ListView into my List list?
The operation of reading ListView data into List generic list should begin after clicking the button "GetData".
I saw the following advice:
[Code]....
but it does not work - the DataItem property of each Item of ListView has null value. The point is that I have generic list with data. I am binding this data into ListView which can be edited by user. After that after click Save or GetData data from ListView is read into generic list of MyClass type.

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"))))

I have been banging my head against this problem for a bit and I think I am stuck. I would like to pull data from a Database to populate a list of possible "clients" to select from on one side. Then using what has been clicked load the client specific data into a tab container on the opposite side. I plan on doing lazy tab loading so I am not sure if that matters. I am really stuck and any help or guidance anyone could give would be greatly appreciated! I understand the basics of data loading and of tab containers, but i am unsure of what to do. I am coding this in C#. Example Mock Interface This is where the data list would be and I want to be able to select something here And update the Tab Panel control here based on the selection from the left side via querying the database.

I've got a problem with my onrowdatabound function. The situation is like this:
protected
void gvSQL_RowDataBound(Object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
switch (Session["Filter"].ToString())
{
case "NonZero":
if (e.Row.Cells[9].Text == "0")
{
e.Row.Visible = false;
}
break;
}
}
}
At the end I need to kill the Session, so my plan is to detect if it reaches the last row. Then I can kill it. Does anyone know how to do this? Or is there someone that knows a better to fix this?

Which one is best in terms of performance and coding best practice?
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.

[Code]....
I can't get these "Dim Owner As String = DirectCast(row.FindControl("lblOwner"), Label).Text" to compile. I think because this is looking for template fields and my gridview is filled in on the fly so they are bound fields. Does anyone know how to get the text out of a bound field?

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.
