I have a gridview with some columns and I need to sort the gridview by a date-column. But it doesn't sort it correctly. This is the code I use:
dt.DefaultView.Sort = "Meldingsdatum asc";
gvOutlookMeldingen.DataSource = dt;
gvOutlookMeldingen.DataBind();
Actually i want to ask which is the best for sorting in Asp.Net is it DataView.Sort Method or List<Object>.Sort() method.
View 1 RepliesI have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..
how to sort a datatable (dataview) so that the second column is ascending but nulls are last.
I'm trying to do the following Date1 ASC, DATE2 ASC (but if DATE2 is null it is last in this Date1 group)
Note: Date1 can never be null so a Date2 that is null should still be grouped in with its Date1.
I have a simple dynamic gridview with following code -
GV = new GridView();
I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

i have a table which showing the food data from my Model, including Name, Amount, Storage and Expiry Date. I wish to either:

I am in VS2008 and in ReporViewer's Design page.
I have "Fruits" as column fields and Months as row fields and Sales as data field.
I have these columns:-
Apple, Orange, Pear.
However, I want it be displayed as
Orange, Pear, apple.
Any work around ?
Also I need a 4th column adding the Apple, Orange and Peer numbers total. How to do it in design view in VS2008 ?
I am grabbing an XML feed an throwing it into a dataset. I am looping through the datatable that is in the dataset and adding a column to the datatable (Distance) that is the result of a calculation. What I then need to do is sort the dataset on the new column (Distance) I added, but it is not working... Here is a sample of my code.
[Code]....
Basically I have a table as follows:
Page Title ¦ DateTime
Home ¦ 20/09/2010 17:25:01
Home ¦ 20/09/2010 16:01:16
Home ¦ 20/09/2010 17:24:01
About Us ¦ 06/09/2010 17:27:01
Home ¦ 03/09/2010 14:25:01
SiteMap ¦ 21/09/2010 17:21:01
I want to get the unique page title but latest date, therefore query result would be:
SiteMap
Home

I have a sorting issue with DataView.
View 2 RepliesI've got a datagrid which i wanted to sort, since i dnt have much knowledge of .Net, so what i did was to save that datagrid in a DataTable, then again save the same DataTable in a DataView, then apply sorting on that DataView. this is the code, and its working fine.
Code:
protected void dgEOBSearchResults_SortCommand(object source, DataGridSortCommandEventArgs e)
{
DataTable dtEOBDocumentListTable = (DataTable)Session["sEOBDataTable"];
if (ViewState["sortExpression"] == null)
[code]...
but the issue comes when the i try to sort the Date Column, the dates are in MM/DD/YYYY format, so if i try to sort the date column, the dates are sorted on month basis, rather than year basis. now i cant change the date format, is there any way to sort dates in DataView?
I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location
123 New York
124 Chicago
125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.
Using ASP.NET Web Forms.I am databinding a DataView to a DataGrid with AutoGenerateColumns set to trueThe final column of the DataView is not rendering.Using the debugger I can see that the column definitely exists in the data grid's datasource. The column is of type decimal and some of the rows in the column have data in them.The column has a column name.The other columns are rendering fine.What's going on?Some more infoFunnily enough, I can set AutoGenerateColumns to false, then just add the columns manually:
datagrid.Columns.Clear();
foreach(DataColumn column in dataView.Table.Columns)
{
datagrid.Columns.Add(new BoundColumn {
HeaderText = column.ColumnName });
}
datagrid.DataSource = dataView;
This works fine. Why can't .NET do this with AutoGenerateColumns?
I have a datatable,columns are(User_id,Name,Address,DOB)
values like(12,abc,delhi,22/2/2000)
(14,pqr,mumbai,13/3/1989)
(8,klm,banglore,17/5/2001)
(9,asd,pune,12/9/1999)
Now I want to sort these rows on DOB in descending order..how can i do so?
I have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("/posts.xml"))
Dim dv As New DataView(ds.Tables(0))
dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet
ds.ReadXml(Server.MapPath("/App_Data/posts.xml"))
'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal)
Dim dv As New DataView(ds.Tables(0))
'dv.Sort = "date"
I'm trying to filter a DataView to return all the rows whose column x starts with a number: The following works in SQL Server:
select *
from dbo.Page
where Name like '[0-9]%'
However, when I try this:
dataView = new DataView( someDataTable, "Name LIKE '[0-9]%'", "Name ASC", DataViewRowState.CurrentRows);
I get "invalid parameter [0-9] with Operator Like" error message. What is the correct syntax to achieve my goal?
var regionNameList = regionDataContext.regionDataViews.Select(region => new { region.RegionName, region.RegionNumber }).Distinct().ToList();
regionnamelist needs to be "order by regionname".
how can i sort the data in col of datatable or other way to sort

I have a GridView in ASP.Net 3.5. I added BoundFields as columns, set DataField and Header Text. Total I have 6 columns like that. Although I set "AllowSorting=True" in design view, when I run this page, all the columns didn't have hyper link that I can click on it and sort that particular column. I bind this column at code behind by using datatable.
gv.DataSource = dtDispatch
gv.DataBind()
i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
View 1 RepliesIn gridview I am able to sort on 1 column as mentioned below, I want to add one more column in sorting, what is the best way to do this,
[Code]....
I am sorting the grid using DataView's "Sort" property. I am passing sort expression and the order in which the grid is to be sorted(ASC or DESC). But the problem is, since the column on which I am sorting the grid is listing the intergers, the sorting is happening as if it is a string. But I need integer sorting rather string sorting on that column.
The grid displays below as ascending order(string sorting)
55
77
8
But I need the columns to be displayed like this(Integer sorting)
8
55
77
