I have one gridview and i want to take all the values in a datatable or dataview.
I tried like this
DataTable gridTable = (DataTable) dataGrid1.DataSource;
but gridTable is showing null, it should not show null because gridview has lot of records with 3 columns
Is there any way i can convert/store a gridview.Datasource records in a datatable or dataview?
I am doing GridView Sorting without ObjectDataSource. For this requirement I need to convert DataTable to DataView, I know I can do that in VS 2008 but How can I do this in VS 2005.

Can we convert the Repeater items back to a datasource?
At post back, I want to convert the repeater items into a datatable which is a datasource was given to the repeater.
HOW TO specify which columns are in a DataView from a DataTable. I want to create a DataView, that only has the columns from a DataTable that I choose, and in the order I want.
Example:
// DataTable_MyTable ~~ Column #0 is for ID. I do not want my view to get this column.
// DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view.
// DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.
DataView DataView_MyView = new DataView(DataTable_MyTable ~~ some how only get the columns I want, and in the order I want ~~);
// DataView_MyView now has only 2 columns.
// DataView_MyView ~~ Column #0 is NAME.
// DataView_MyView ~~ Column #1 is TYPE.
converting a DataView to a DataSet?
I have a DataSet 'programs'. I want to sort if before passing it to a user control where it will be rendered.
I created the DataView and sorted it successfully like so:
[Code]....
The line of code to pass my old (unsorted) dataset to the UC is like this:
[Code]....
What is the syntax for passing the dvPrograms to the UC in a similar manner?
I have tried the online converters, and none of them that I have tried will accurately convert this. It still tries to add a .Item property to the dataview and that does not exist in c#. I know this is simple...
dv.Item(e.Item.ItemIndex).Row.Item(1)
I want to get all the data of Dataview in a datatable (which also include the sorted feild)
I have a code
DataTable dt = new DataTable();
DataView dv = (DataView)ViewState["dv"];
dv.Sort = sortExpression + direction;
gvCustomers.DataSource = dv;
gvCustomers.DataBind();
I want to put this data view object to a table as it is. means if the coloum is sorted , then the sorted data should comes to datable or dataset
DataView Dv = new DataView();
Dv = dts.DefaultView;
Dv.Sort = "ReportName";
dset = new DataSet();
DataTable datable = Dv.Table;
dset.Tables.Add(datable);
I convert dataview to datable and sorting.dataview sorting grid. But I covert dataview to dataset.not sorting in gridview...
I am having trouble converting a ienumerable to a datatabe here is the code:The problem is in the following line-
ViewState("dt") = elements.CopyToDataTable()
Dim dt As New DataTable
Private Sub DisplayAuthorLastName(ByVal strLetter As String)
[code]...
i try casting the gridview datasource to datatable using the following code but the datatable always nothing.
Dim DT As New DataTable
DT = DirectCast(gv.DataSource, DataTable)
the gridview is bound using dataset at code behind without using sqldatasource.
i m trying to filter the gridview without geting the data from database, is there is another way to do this?

Label2.Text = Convert.ToString(gd.GetDesc(pid));

View 4 RepliesI 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 dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.
[Code]....
It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?

View 2 RepliesHow to bind gridview using dataview in the code behind?
View 1 RepliesASP.NET 3.5
I've got a Gridview bound to an objectdatasource. Sorting is enabled in gridview, but objectdatasource isn't doing any sorting. I can pick up the unsorted datatable from the Selected event of the objectdatasource, but I really want the sorted version. Is there any event on the gridview where I can access the sorted dataview it must be using internally?
Why am I asking? We're using paging as well (i.e. truncated data in gridview) and I want to loop through the full sorted dataview to find the primary key value to set selectedindex.
