View 3 RepliesI have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
Here's my code (it doesn't work right now).

View 2 RepliesI have a datatable with 17 columns and a bunch of data. I wnat a datatable with only 6 of the columns and the data for those 6 columns. So I need a subset of the original datatable. How do I loop through the original datatable with 17 columns and end up with a datatable with only the 6 columns I want with the corresponding data for those 6 columns?
View 4 RepliesI am getting this error whilie bulding project. i simply has defined a datatable accessing its rows and columns. don't knw why it says Columns is not a member of 'DataTable.

Im trying to retrieve a datatable that I put into a session variable, however when i do it apears that there are no columns... I have done this before in VB.NET, I'n now using C#, and it worked perfectly, and as far as i can see there is no change in the code other than the obvious syntax changes.
EDIT: The dt (in part 2) variable has the right data when i look in the data visulization window, but i have noticed that the other properties associated with a datatable are abscent. When i hover over a normal looking datatable with my mouse it looks like the following: " dt ----- {System.Data.DataTable}" but in the class im working on it just looks like "dt ----- {}". Also, after I return the session variable into the dt I clone it (dtclone = dt.clone(); ) and the clone is empty in the data visulizer.... what on earth!
EDIT 2: I have now also tried converting the first datatable to a dataset, putting this in the session variable, and recoverting it back to a datatable in the class. Am starting to wonder if it is a probelm with: dt.Load(sqlReader); The data does appear after this step though in the dataset visualiser, but not after being cloned. Code below.
1) SQL command in a webhandler, the results of which populate the datatable to be put into the session variable.
DataTable dt = new DataTable();
SqlDataReader sqlReader= default(SqlDataReader);
SqlDataAdapter sqlAdapter = new SqlDataAdapter();
sqlReader = storedProc.ExecuteReader(CommandBehavior.CloseConnection);
dt.Load(sqlReader);
System.Web.HttpContext.Current.Session["ResultsTable"] = dt;
2) Part of the code in a class which performs calculations on the table:
DataTable dt = (DataTable)HttpContext.Current.Session["ResultsTable"];

View 1 RepliesI'm trying to update fields in a DataTable. The field I'm trying to edit is a date, I need to format it.
foreach (DataRow row in dt.Rows)
{
string originalRow = row["Departure Date"].ToString(); //displays "01/01/2010 12:00:00 AM"
row["Departure Date"] = DateTime.Parse(row["Departure Date"].ToString()).ToString("MM/dd/yyyy");
string newRow = row["Departure Date"].ToString(); //also displays "01/01/2010 12:00:00 AM"

View 1 RepliesI have a datatable with the ordering of its DataClassIndex column before editting:
DataclassIndex 0 1 2 3 4
When I start modifying some other cells in this datatable, the ordering of DataClassIndex column changes to something like this
DataclassIndex 3 4 2 1 0
How can I modify a datatable content without altering the original order of the datatable.
