View 1 RepliesWeb Forms :: Sort Datatable Without DefaultView.Sort?
Apr 20, 2010I'm looking for a way to sort the rows of a datatable without setting the DefaultView.Sort to a specific column. I have a datatable in session that users can add records to. I want them to be able to sort the data by clicking on a button. But new records added after that need to show up at the bottom of the list until the sort button is clicked again.
View 2 RepliesAccess The Group Of A Linq Group - By Query From A Nested Repeater Control?
Mar 26, 2010I'm using a linq group by query (with two grouping parameters) and would like to use the resulting data in a nested repeater.
var dateGroups = from row in data.AsEnumerable()
group row by new { StartDate = row["StartDate"], EndDate = row["EndDate"] };
"data" is a DataTable from an SqlDataAdapter-filled DataSet. "dateGroups" is used in the parent repeater, and I can access the group keys using Eval("key.StartDate") and Eval("key.EndDate").
Since dateGroups actually contains all the data rows grouped neatly by Start/End date, I'd like to access those rows to display the data in a child repeater. To what would I set the child repeater's DataSource? I have tried every expression in markup I could think of; I think the problem is that I'm trying to access an anonymous member (and I don't know how.) In case it doesn't turn out to be obvious, what would be the expression to access the elements in each iteration of the child repeater? Is there an expression that would let me set the DataSource in the markup, or will it have to be in the codebehind on some event in the parent repeater?
C# - Select DataTable (only Some Values) From _GetDisplayData And GROUP Data By Days Where Group Rules Is Different For Different Columns
Mar 4, 2010 Stack-Overflow :3 I've got a kind of hard-case question.
So I'll try clearly explain my idea with my poor english :/ need select to DataTable SOME values from ???_**GetDisplayData **procedure for each day of previos month (GROUP IT) where group rules for different columns is different
I need to select some values in stored procedure from other stored procedure like this :
SELECT X FROM Y_Procedure(@ProcedureParameters)Also I need to select from dynamic SQL Procedure like
Y_Procedure=@Y+'_Procedure'
SELECT X FROM Y_Procedure(@ProcedureParameters)
Also I need to load it to DataTable :-/INSERT INTO @Report (CellHorizontal, CellVertical, CellValue) --to TABLE
SELECT Date,X2,X3 FROM Y_GetDisplayData(@Param)
SET NOCOUNT OFF;
SELECT *
FROM @Report
GetDisplayData works as select with parameters and that doesn't returns SQL DataTable
And there is no way to recode GetDisplayData's procedures, it's just constant procedures for me.Finally I need to Group nodes from this table
INSERT INTO @Report (CellHorizontal, CellVertical, CellValue)
SELECT T1.Date,
IF ((Select grouptype...)=1) T1.X2 + T2.X2
ELSE IF ((Select grouptype...)=2) AVG(T1.X2,T2.X2),
IF ((Select grouptype...)=1) T1.X3 + T2.X3
ELSE IF ((Select grouptype...)=2) AVG(T1.X3,T2.X3),
(SELECT T2.Date,X2,X3 FROM Y_GetDisplayData(@Param) T2
WHERE T2.Date>T1.Date AND T2.Date>=T1.Date)
FROM Y_GetDisplayData(@Param) T1
GROUP BY EVERY DAY ???--and here is epic fail
I can make all stuff on asp server :And C# allows me to use something like SelectCommand = IzmProc + "_GetDisplayData"; And then I will work (select special data) with DataTables on ASP.NET Server but it's better to make all on SQL ... But looking like it's just unrealizable on SQL >_<
I gonna think about C# realization,but my code is very weird , got errors and doesn't works >_<

Forms Data Controls :: Gridview Sort Expression - How To Reset A Gridview Or Prevent It From Doing A Sort
Sep 23, 2010Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:
[Code]....
Here is an example of just one of those SLQ statements inside GetSQLQuery:

ADO.NET :: Returning A Blank DataRow?
Oct 19, 2010I have a method like
public DataRow
GetItem(ENTITY_TYPE
EntityType, long EntityID)
This fetches a row and returns it. Pretty simple.
However I can't test in the method to see if the row was fetched, as the method has to end with:
return ds.Tables[0].Rows[0];
If the row wasn't fetched, this errors as there is no row at position 0.
I can't do this:
DataRow dr;
if (ds.Tables[0].Rows.Count
== 1)
{
dr =
ds.Tables[0].Rows[0];
}
return dr;
.. because then I get an error that I can't return an uninitialised variable (dr).
I can't stipulate what the columns are and return a "blank" DataRow as far as I can see, because it's dynamic so I don't know what the columns will be. There doesn't seem to be a way to instantiate the DataRow return var except by assigning, er, a DataRow. Which I may not have.
I don't really want to switch to using the ItemArray and pass arrays about, I'd rather just pass the DataRow object as this is in a loop which might process a lot of rows.

Getting The Bound Datarow Of A Datagrid On Postback?
Feb 18, 2011I want to find out the bound datarow or datatable of a datagrid on postback. I have a ButtonColumn in the grid. On click of the button, I'm trying to determine the datarow so that I can access the primary key and pass it to another page. The primary key is not bound and therefore not visible in the row.
For example I have a list of Customers, with an edit button. On clicking of the edit button, I want to open CustomerEdit.aspx?id=10. I am able to trap the click event on the server side in the DataGridCustomer_ItemCommand event. But am not able to get access to the datarow of the e.Item.ItemIndex.
On postback I'm NOT binding the datagrid. On accessing DataGridCustomer.DataSource, I get "Nothing". Is there a way to get the DataSource or the Datarow?
C# - Moving From String Array Into Datarow

Then i tried converting into DataRow. But it says. "object reference not set to an instance of an object"
DataRow dr = null;
string[] strconcat = new string[100];
dr["concat"] = strconcat[i];
Edit-- Actually i was trying put these string array values into dropdown (ddchooseadeal).

ADO.NET :: Copy Datarow Content Without Foreach
Jan 12, 2011 have 5 datatables and will add up more, what i need is to copy the content(rows) of the each and every datatable in a separate datatable. All the datatable columns are same. Is that possible without foreach statements. We can achieve the results in foreach
but the datatables will contain more rows, so iterating each and every datatable will affect the performance.he code i implemented is exact thing i need, but without foreach statement. To copy content of each and every datatable and put the content in a final datatable
DataTable dat = new DataTable();
DataRow Dr = dat.NewRow();
dat.Columns.Add("c1", typeof(string));
Dr[0] = "01";

How To Assign DataRow To Variable In Grid
May 10, 2013Right now I am using a grid control from ComponentOne which I have to stay with. When I click an link in the row which fires a grid_ItemCommand event one of the parameters passed is e As C1.Web.C1WebGrid.C1CommandEventArgs. I want to change it where I am selecting a row with a checkbox in a column and then click a button to process the row selected. So I need to get the value it is putting in e and pass that which is used in another sub.
Here is how e is assigned to "row" as DataRow.
Code:
Private Sub grid_ItemCommand(ByVal sender As Object, ByVal e As C1.Web.C1WebGrid.C1CommandEventArgs) Handles grid.ItemCommand
Select Case e.CommandName
Case "Renew" ' Renew barcode
Dim row As DataRow = CType(e.Item.DataItem, DataRowView).Row
