In my simple starter asp page I create a DataTable and populate it with two rows. The web site allows users to add new rows. My problem is the DataTable doesn't save the information. I've stepped through the code and the row gets added but the next time a row is added it's not there, only the original two and the newest one to get entered.
I have gotten around this, in an inelegant way, but am really curious why the new rows are being saved.
My code:
protected void Page_Load(object sender, EventArgs e)
{
_Default.NameList = new DataTable();
DataColumn col = new DataColumn("FirstName", typeof(string));
_Default.NameList.Columns.Add(col);
col = new DataColumn("LastName", typeof(string));
_Default.NameList.Columns.Add(col);
DataRow row = _Default.NameList.NewRow();
row["FirstName"] = "Jane";
row["LastName"] = "Smith";
_Default.NameList.Rows.Add(row);
row = _Default.NameList.NewRow();
row["FirstName"] = "John";
row["LastName"] = "Doe";
_Default.NameList.Rows.Add(row);
}
protected void AddButton_Click(object sender, EventArgs e)
{
DataRow row = _Default.NameList.NewRow();
row["FirstName"] = this.TextBox1.Text;
row["LastName"] = this.TextBox2.Text;
_Default.NameList.Rows.Add(row);
_Default.NameList.AcceptChanges(); // I've tried with and without this.
}
I've tried saving them to GridView control but that seems like quite a bit of work. I'm new to ASP.Net but have done windows programming in C# for the last two years.

I am working on a web application that is consuming a Dataset returned by a web service. As the application is running I store that Dataset as a session variable to be used over and over again as the user navigates to the different pages that will edit the tables within the dataset. The idea was the user will only have to wait for the data once when the application loads then the application would use the session variable until the user saves the changes they made, when that happens it would pass the edited tables to the service to update the database. Is there problems with this design and the storage of the Dataset and Datatables as a session variable?

I am using ASP.NET and Sharepoint and I'm getting a list of documents and displaying them in an SPGridView (sharepoint grid view)
How I seem to be only able to add data as a string to my DataTable.
See the line :
row["Title"] =
"<a href="" + itemUrl +
"">" + item["Title"] +
"</a>";
Is there anyway I can add a control here (say for example a HyperLink)
DataTable myDataProvider = GetDatatable();
view = new
DataView(myDataProvider);
//grid is of type SPGridView (sharepoint grid view)
[Code]....

I need to pass the data from GridView1 to a DataTable, and then pass the DataTable to GridView2 and preview it. I have BoundFields and ImageFields in the GridViews. I think I am doing something wrong but I can't figure out how to do it. I know I have to iterate through the GridView.Rows, but I don't know how to pass it to the DataTable.

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
