VS 2008 - Sorting Date Column In DataView
Jul 12, 2011I'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?

DataSource Controls :: Sorting And Selecting From A DataView Or DataTable?
Apr 23, 2010I am trying to do something I thought would be simple but something isn't working for me.
I have a DataTable that I need to sort by a price ascending, then select an 'nth' row value. The 'nth' value is the row count/10.
[Code]....
What happens is I get the "nth" value from the original tblDeals.

View 2 RepliesForms Data Controls :: Paging On A Different Column Than The Sorting Column
Sep 26, 2010Situation: SQL database, Linq to SQL class a ASP.NET page with a LinqDataSource and a gridview. The table has a ID field, a date field and a Serialnr field. In my Grid I like to Page on the datefield but to sort on the serialnr field ( or a selectable other field). Is that possible? Standard the paging is always done on the sort field and when you select a different sort field the page jumps back to the first page., and paging is then done over that sorted column.

Forms Data Controls :: Determining A Row And Column In A Dataview?
Aug 9, 2010I know how to do this in a datatable but I would just like to learn how to do it in a dataview.

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.
Column In DataView Not Rendering When Databound To DataGrid (or RadGrid)?
Sep 7, 2010Using 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?
Forms Data Controls :: Converting Dataview Column Info Into Integer?
Jan 15, 2010I 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"

View 1 RepliesSorting A GridView Column Related To Other Table?
Jun 10, 2010i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName.
I have tried this without success(" Cannot find column ERP_Customer.CustomerName "):
<asp:TemplateField HeaderText="Customer" SortExpression="ERP_Customer.CustomerName" >
A tried also the DataViewManager, but i've a problem to detect the table to sort:
[code].....
I have to apply the sort on a distinct table of the DataViewManager, but this table would differ on the related tables.
I have bound the TemplateColumns in Codebehind in RowDataBound-Event f.e.:
Dim LblCustomer As Label = DirectCast(e.Row.FindControl("LblCustomer"), Label)
LblCustomer.Text = drCharge.ERP_CustomerRow.CustomerName 'drCharge inherits DataRow
What is the recommended way to sort a GridView on columns related to other tables? I could build a custom datatable with the customername instead of the foreignkey and bind this column to the TemplateField. But then my huge dataset in the model makes no sense anymore.
EDIT: I have a model with a Dataset. I'm binding one Datatable(ERP_Charge) from it to my GridView(actually i take a Dataview from that Table). In this Datatable are columns that are related to other Datatables in the Dataset(relations are defined). When i want to make the grid sortable its no problem on the columns that belong to ERP_Charge.
But the columns with foreign keys to other table could not be sorted because the Gridview shows f.e. not the CustomerID but the Customername. I get the Customername in RowDataBound. Normally i would join the tables and add a Datacolumn for the Customername.

How To Gridview Sorting - Column Data Vanishes
Aug 18, 2010I have a Gridview, which I bind to a Dataview programtically. My Gridview has 11 columns. Sorting works fine as long as I do not remove any columns programtically.
In certain cases I remove 2 of the columns from the Gridview. Still not a problem. All the data is properly displayed however the problem occurs when I sort one of the columns. I sort the Dataview and bind to the Gridview again. Data from two of my columns just vanishes. Both of these columns are based on ItemTemplates. The columns are still displayed but just empty cells.
