C# - Updating Rows In DataTable?
Nov 22, 2010
I'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"
}
How come this isn't getting updated?

Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??

I 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 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).

I 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.

Exporting DataTable data to CSV file. It is working fine as expected as long as the export records are less than 65,536. When the records are more than 65,536 , only 65,536 records are shown in CSV file (remaing records are not shown). When the export is done(with more than 65,536 records), opening the file shows below message window. File is not loaded completely. When the Ok button is selected, below text displayed...
This message can appear if: You are trying to open a file that contains more than 65,536 rows or 256 columns. To fix this problem, open the source file in a text editor such as Microsoft Word. Save the source file as several smaller files that conform to this row and column limit, and then open the smaller files in Excel. If the source data cannot be opened in a text editor, try importing the data into Microsoft Access, and then exporting subsets of the data from Access to Excel. You are trying to paste tab-delimited data into an area that is too small. To fix this problem, select an area in the worksheet large enough to accommodate every delimited item.
Notes: You can not configure Excel to exceed the limit of 65,536 rows and 256 columns. By default, Excel places three worksheets in a workbook file. Each worksheet can contain 65,536 rows and 256 columns of data, and workbooks can contain more than three worksheets if your computer has enough memory to support the additional data. Solution:- Seems like here is the suggested solution. But it takes ages to export and show data. An export is done about 15mins ago, still it is doing that. Has anyone managed to find/resolve this issue?

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 using Compute for summing up a datatable which has a condition. Sometimes, there are no rows inside the datatable matching my criteria so I get an exception on ComputeObject cannot be cast from DBNull to other types.Is there a way to check/filter the datatable to see if it has the desired rows, if yes only then I apply Compute.
total = Convert.ToDecimal(CompTab.Compute("SUM(Share)", "IsRep=0"));

I have a datatable for which i'm defining a dataadapter. I'm specifying an updatecommand with sqlparameters for the dataadapter I set the updatecommand's parameters using the following overload:
[Code]....
The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

I have a DataTable for which a PrimaryKey constraint has been set to be a combination of an integer column and a datetime column. When I try to 'Find' a row by saying,
dtFunds.Rows.Find(iContainerIndex)
I get a null value. iContainerIndex has been defined as an object array of size 2 with the integer ID and date values in it.
When I set a breakpoint in my code, I see that the very same values are present in the datatable.
If I try to execute, DataTable.Select() method with the integer column filter, I get a result - but returns no result when called with the date column filter.
What am I doing wrong here? The very same DateTime value is present in the datatable.

I am trying to use a SqlDataAdapter to fill a DataTable, which I use as a data source to a DataGrid. The query is fine, at least when I run it manually in SSMSE. When I do the fill operation, the table gets the right columns, but no rows. The most frustrating part of this is that the code is identical (with a different query) on a different page. I cannot post the query, but my initialization code looks like this:
SqlCommand areaDAC = new SqlCommand (areaQuery, connection);
areaDAC.Parameters.Add (new SqlParameter ("@param", System.Data.SqlDbType.NVarChar, 50));
m_areaDataAdapter = new SqlDataAdapter (areaDAC);
Then to use it:
m_areaDataAdapter.SelectCommand.Parameters["@param"].Value = "Filter Val";
DataTable table = new DataTable ();
m_areaDataAdapter.Fill (table);
At this point, table has the right number of columns and no rows. I know the parameters are being added correctly, I know that data exists for the given query.
