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:
What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.
i have retrieved data from the database and stored in dataset.i have to add an additonal row to it,update the data in data set and delete data from the data set..
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.

The dataset is being populated, however when the page renders, the data nor the gridview are visible. I have tried using both IE and Firefox, binding / not binding the columns, AutoGenerateColumns Y / N with no success. As I am new to all of this ( VS2008, ASP.NET, C# ) I can't help but to think I am overlooking something basic.
I am using the following : - VS 2008 - MS Vista SP2 - Oracle XE ( local )
I was searching for my problem for last couple of days. But coudn't find a better solution. So here I go again. What I did which worked great: I was going to a asp page with pre populated Dataset (dataset is already loaded with data), for a GridView. If I do the following .... the GridView shows all the data (with the fields Dataset comes with).
[Code]....
Now what I am trying to do: I am trying to do exact same thing but instead of using GridView, I would like to display data in a FormView. So now I tried to do this
[Code]....
PROBLEM: I can see the FormView Header with text "Test Dataset With FormView" and below the Header it displays the page numbers. I know that I have 3 data in the data set and I can see 3 page link in the FormView. But PROBLEM is it doesn't display any Field / Data. Not sure why it is doing this
Note that I wouldn't know what field to display in the FormView. Whatever I have in the Dataset I need to display. Is there any work around to accomlish my work (maybe by not using a FormView, but other conrol ?). My original goal is to Display Data in a Form View Format (One data at a time
I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
