Forms Data Controls :: How To Convert DataView To DataSet
Jul 27, 2010
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 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?

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

Is there a straightforward way to create a dataset after querying a dataview? The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().
The query looks like:
Dim dvQueryView As DataViewdvQueryView = (dataview object of large dataset)
detailTableQuery = From rowView
As DataRowView
In dvQueryView _
Order
By sSortOrder _
Select rowView _
Skip nQuerySkipRow _
Take nQueryCountRows
I only want a small selection of records from the large dataview and use those to create a smaller dataset. The large dataset stays in place while multiple views are created from it, and then from those views I want to create the smaller datasets.

I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value.
What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML:
[code]....
How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms?

Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.

I'm having trouble using entities: I still want to use entities on my "DAL" layer, but in "BLL" layer I want to return not a collection of entities but just a Dataset with all the table I got back from Stored Procedure. How can I do that?
The presention layer don't know anything about entities, if I can get just a dataset from "BLL", it will be very easy to work with it as it was before. Only the DAL and BLL layers will be changing.
P.S.
Does entities support stored procedure that is returning more than one table, I mean more than one entity?! If not, This is another BIG problem Microsoft didn't think about.
I must tell you the truth: I am really disappointed about using Entities. There is no logical support for Stored Procedure and too many problems when you want to have N-Tiers. It is like Microsoft have done only half of the work needed so this will be really usefull.

I want to sort the string which is in the format given below15% Test;15% Sear;40% Santhosh;30% Jeeson;
The output that I am expecting is
40% Santhosh;30% Jeeson;15% Sear;15% Test;
I wrote the following code but it does not work .
string str = "15% Test;15% Sear;40% Santhosh;30% Jeeson;";
Console.WriteLine(str);
DataTable dt = new DataTable("SortBenchMark");
DataRow dr;
dt.Columns.Add("Weightings", typeof(int));
dt.Columns.Add("BenchMark", typeof(string));
string weightings = string.Empty;
string BenchMarkName = string.Empty;
foreach (object o in str.Split(';'))
{
if(o.ToString().Length > 0)
{
dr = dt.NewRow();
dr["Weightings"] = Convert.ToInt32((o.ToString().Split('%'))[0].ToString().Trim());
dr["BenchMark"] = (o.ToString().Split('%'))[1].ToString().Trim();
dt.Rows.Add(dr);
}
}
dt.AcceptChanges();
DataView dataview = new DataView(dt);
dataview.Sort = "Weightings DESC,BenchMark Asc";
string final = string.Empty;
foreach (DataRow drow in dataview.Table.Rows)
{
final += drow["Weightings"].ToString().Trim() + "% " + drow["BenchMark"].ToString().Trim() + ";";
}
Console.WriteLine(final);
Console.ReadLine();

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.

I 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?..

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.

I'm trying to export a filtered dataview to excel. The code to export works just fine but it exports all the records, not just the ones I filtered on. For example, I have three dropdowns and the dataview seems to work just fine filtering on the dropdown parameters because it shows up correctly in my datagrid on my screen.
This line of code is where I am confused.

Im trying to populate my formview from a dataview in the codebehind and the order in which things are happening is causing it to fail.my formview itemtemplate is setup with some eval("fields") which is initially not populated (nothing bound to it) and the page loads ok. i think click on my graph which generates a query and populates a dataview.i then assign that dataview to the formview and run the bind.what happens when i actually run the app is that it says no data is bound to it.i set the debugged to stop at the point where my DV is assigned to my FV and the FV shows a data item count of 1 (as expected) if i keep stepping it puts me in to the eval statements on the aspx page says the data isnt bound.
the error i get is
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I am using a dataview to read a certain record from a database and then adding these values to different elements on a form (label, textbox) ..
One of the fields is a date/time and i only want to display the date without the time..
code:
{on page load}
Dim dv As System.Data.DataView = CType(DEDS.Select(DataSourceSelectArguments.Empty), System.Data.DataView)
lbl_startdate.Text = dv.Table.Rows(0).Item("'<%# Eval("evt_startdate","{0:d}")%>'").ToString()
' DEDS is my SqlDatasource ..
'evt_startdate is the date field coming from the DEDS datasource
.. It's not working .. I'm not sure how i should alter the date format ..
