Getting records From DataBase using DataTale which contain 1000 Rows, then binding to GridView using Generic List. Like above Example
GridView1.DataSource= GetData();
GridView1.Binding();
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.
I have a problem i just cant get around...I'm trying to sort the contents of a gridview that gets filled from a List<T>.
(working in DAL, BLL & Presentation layers).
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"))))
I have a following generic list method that contains some data for a gridview. I need to supply edit and delete functionality for it.
List<students> List(string id)
{
List<students> st = new List<students>();

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.
I get this error when run the page
DataBinding: 'System.Int32' does not contain a property with the name 'item'.
protected void Page_Load(object sender, EventArgs e)
{
List<int> item = new List<int>();
{
item.Add(25);
item.Add(50);
item.Add(520);
item.Add(543);
item.Add(543);
item.Add(55);
};
GridView1.DataSource = item;
GridView1.DataBind();
}
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" ShowFooter="true">
<Columns>
<asp:TemplateField HeaderText="Sub total">
<ItemTemplate>
