I have a DataSet that I bind to a GridView control. I want to only show certain columns from the DataSet. Should I do that with my SQL query (that I use to populate my DataSet) or somehow with a DataView?

View 2 RepliesI have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.

View 6 RepliesI have a dataset.table which has some null values. am trying to trasform this using xslt to display like excel. If the value is null, then that node is ommitted by the xml. i tried deafulting the null values from the database itself and thats not generic. Handling null values is troublesome. I tried couple of methods to default null values by looping and thats not optimal solution. I used LINQ to handle null values but couldnt comeup with a neat solution. what am looking for is a generic optimal solution to handle these values.
View 2 Replies1. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?

I have an emergency request that I need to sort it out very quickly as I did not notice it early :(.
I have a dropdownlist, the contnet in the gridview (sqldatasource connection) changes based on the value the user slects, say I have play1, play2 from the dropdownlist, I would like to show column1, column2 and column3 with user selects play1; show column4, column5, and clomn6 when use selects play2; the datatable actually includes all 6 columns.
I understand that I need to use something like RowCreated event, and I need to set up condition based on the dropdownlist value, but I dont really know how to.
I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.
On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.
[code]....
dv = new DataView(table);
Table.Columns.Add("ID", typeof(string));
table.Columns.Add("Type", typeof(string));
table.Columns.Add("EmpName", typeof(string));
table.Columns.Add("Manager", typeof(string));
row = table.Rows.Add();
row["ID"] = result["ID"].ToString();
row["Type"] = result["Type"].ToString();
row["EmpName"] = result["EmpName"].ToString();
row["Manager"] = result["Manager"].ToString();
Then I am adding boundfield to gridview for all 4 columns. Now I want to check if "Type" column contain "Sales" thne do not show "Manager" columns. Let me know can I do this?

View 2 RepliesI am using subsonic in asp.net forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.
in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.
just as an update i have been playing with the idea of something like this:
DataSet ds = new DataSet();
ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1)));
ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod)));
DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]);
ds.Relations.Add(relation);
still working this out though.

View 2 RepliesI have a problem, I need to get a date from an SQL database using a dataset.xsd.
To do that, I have created a query in the TableAdapter called GetDataByFecha:
SELECT fecha
FROM T_Tickets
WHERE(fecha = @fecha)
in C# I do this:
DateTime T_fecha;
T_fecha = Convert.ToDateTime(ticketsAdapter.GetDataByFecha(fechaTicket));
but, when I compile it I get this error:
cannot convert a 'T_TicketsDataTable' object to 'System.IConvertible' type.
I have dataset which is called at page load event. Also every time i clicked on refresh it will call refresh function where it store updated values from database.
Now I want only updated fields row and want to store into datatable or another dataset.
I dont want to cmp each and every iteration of the dataset. I used Getchanges() of dataset but not working.
