View 1 RepliesI have had a persistant problem, which occurs in "Visual Web Developer 2008" express, but also in "Visual Studio 2010"
When I drop a data control onto my webpage, and the select "Configure Data Source", the dialog box opens, but when I try and browse for the data file (could be MDB or XLS) the data file does not appear in the "Select (XML/MDB) file" - in the example below a XML file. If I set the filter to "All Files (*.*)" I can see all of the files EXCEPT the XML files.
The project is a web project, and is set to HTTP - using my local IIS.

I recently started using SSRS 2010 and I didnt come across this issue in 2005 or 2008 versions of reporting services.
I have a report that drills down to child report1 and then that drills down to child report 2 but clicking a field in the report.
When I click on the link on the first report to go to the second report. I get this error message
"A data source instance has no tbeen supplied for the data source ''reprort2dataset"
I am not sure how to handle this error.
All reports run fine stand alone, but when I try to link them up I get that error.
I have a report viewer running the reports in an aspx page.
Where and what am i missing?
this code produces some error:
DataSet ds = services.getOrdersReport(1, "", DateTime.Parse(System.DateTime.Now.Date.ToShortDateString()));
ReportDataSource datasource = new ReportDataSource("JMJ", ds.Tables[0]);
rv.LocalReport.DataSources.Clear();
rv.LocalReport.DataSources.Add(datasource);
rv.LocalReport.Refresh();
ERROR :
A data source instance has not been supplied for the data source 'dsOrders_tblOrdersReport'
'dsOrders_tblOrdersReport' -- name of the table designed in dataset.XSD
I am getting the following error while i bind the dataset dynamically in reportviewer(Asp .net 4.0) . I have binded the dataset using stroedprocedure.
Error:A data source instance has not been supplied for the data source 'DataSet1'.
I don't know it happen just to me or Others have the same situation too . All the time when i bind a DataControl to an ObjectDataSource in "Configure Data Source" wizard of ObjectDataSource,when i set parameter source as "Control" in "ControlId" DropdownList there are TWO Item of every control in the WebForm , while it make sense be one.

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?
I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?

View 4 RepliesI'm creating a page that allows the user to create a new object that will later be stored in the database. The problem is that the design of ASP.NET data controls seems to insist upon only working with pre-existing data that has been stored in a database (or XML, etc...).
I'm basically trying to get the user to compose a list of items and specify a quantity for each item. I could do this by generating table rows but the rows are lost at each postback. The data view controls seem to be designed only to be bound to a data source but until the list is complete, the data can only be in memory.
What control is appropriate for this and how can I achieve this with that control?
I would like to dropdown box to show only starting from second row of the table. How to use data reader to do it?
View 9 RepliesI am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?
I am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)
This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid
