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 wants to display the related informations of each record of dataset. That mean, dataset having rows for A,B,C and etc..
Then i wants to display the information in same Gridview of each record(A,B,C). i wrote the below my coding, it dispaly info of the last row of dataset only. pls correct the coding.
I am trying to write a stored procedure that takes out a list of blog entries from a table (tblFeedEntry) as well as the amount of comments that each blog entry has gotten (tblFeedComments) but all I can get is the total amount of comments of all blog entries together, displayed on all entries. This is how my code looks today:
[Code]....
I am guessing that the problem is that the declared variable is not picking up the id of the blog entries, instead it picks up everything. The original select and the select in the declared variable are not connected. How do I connect them?
I am moving to the world of ASP.NET from an Access VBA / VB6 background and having read a few books on the subject I am still confused about communicating with SQL server in VB with ASP.NET.
As a very quick explination I am used to communicating with the server by passing strings containing the data I want to write (or read) such as:
[Code]....
I do not seem to be able to work out from ALAX, Dynamic Data, Bound Controls, DataViews, connecting to services with SOAP, DataSources and all of the other methods of database communication in ASP.NET which is the right system to do the simple reads and writes in SQL that I want to do.
At present I have a page with all of the controls on it required to collect a block of data I want to insert, it is all now fully validated but although I can build the SQL INSERT command in a string I cannot figure out how to fire it over to the local SQL Express server. Am I even doing this correctly or do I need to look at other controls?
I have ported an asp.net application form SQL Server Express to SQLCE 3.5 in Visual Studio 008. Although not recommended, everything works like a charm, except for creating datasets for use in SRSS reports.
The Dataset Designer lets me design and test the Tableadapter perfectly, but the XSD fails to compile, and returns error message :
Failed to generate code. Exception of type 'System.Data.Design.InternalException' was thrown.
i am using sp_helptext to retrieve a query in a dataset. the problem is, i am getting line breaks when retrieving the query in the dataset.
how to retrieve the query into dataset without the possibility of any linebreaks i.e. the query should be retrieved as it has been written by the user.
iam trying to connect dataset to an sql server 2008 iam using asp.net 3.0 but when i try to add a stored procedure to a dataset it gives an error "An unexpected error has occured" Error message:unexpected error
i dont know what it is i have converted entire asp.net 2.0 with sql server 2005, to asp.net 3.0 n sql server 2008 already configured dataset works fine, it is just that iam unable to add stored procedures to new datasets
I need to retrive the id of the inserted record to use it with another table as a FK when the user click the button this is my code that insert the record and the id in auto-increment:
[Code]....
I tried to select the id after inserting using a sqlcommand but it gave me the following error The INSERT statement conflicted with the FOREIGN KEY constraint "FK_masc_img_Mascotas". The conflict occurred in database "ads_site", table "dbo.Mascotas", column 'IDMascotas'. The statement has been terminated.
is there anyway to pass in a Table Name to a DataSet?
I'm executing a stored procedure that is returning several recordsets. I have no problems w/ changing the DataTable's name from my Code Behind, but I was wondering if there was anyway the stored procedure could actually pass back the name of each recordset/datatable?
I have to know how to achieve the following senario in an web application,I have a search functionality, where i will give some parameteres which are used as input to my select query in sql database.
Once i click the start search button the parameters will go to database and execute the query. and display the result in application.If i click the Stop Search, i want to retireve the records which are available till that time. How can this be achieved in .net
But the result is it only insert the first row of the HQDS dataset...then it will give this error :"Violation of PRIMARY KEY constraint 'PK_BRANCH'. Cannot insert duplicate key in object dbo.TS_BRANCH'.The statement has been terminated.
If I comment this line : Destadapter.Fill(HQds, "Testresult")
It doesn't give any error and also it doesn't insert anything to the database.
Violation of PRIMARY KEY constraint 'PK_TS_BRANCH'. Cannot insert duplicate key in object 'dbo.TS_BRANCH'.
I am reading xml file using dataset.readxml() method. after this i want to send this data to the database. I want c# code to create a database in sql sever and push watever data in the dataset to that created database.... i am dealing with many xml documents. some could be of same format.. lets say... if 2 docs of same format exists... then it shud not create new database or new tables.. it shud push the data to the suitable format...as i am a newbie its a bit confusing for me... i dont even have any idea on how to proceed with this.
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:
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.

Problem:
When designing my first .aspx on PC and testing via localhost; all is well.
When move to server I get this error msg:
"The type specified in the TypeName property of ObjectDataSource 'ObjectDataSource2222' could not be found."
I have been reading for a solution for the past three days.
My reading tells me that there should be a reference somewhere in the web config file to id the business object dataset , but do not see any. No luck in surfing for a tip either.
I thought Visual Studio 2010 was a rapid app that allow one to design and test on PC and move easily to server for production. I am I expecting to much.
I am suing xsd file in my app_code file and It gets data from stored procdure. But I am failling with update and delete functions. Am I doning something wrong ?

I have a problem that I have been trying to solve the past two days, but I cannot figure it out...I have a folder which will have 60-70 Excel Files or CSV Files (they are right now). There are no headers in them, but they all have the same # of columns and the columns are in the same order in each fileI need to read each file in the folder, grab the data from the file and put it in a Database file. So all files will be read and then the data from them I guess put in a DataSet and then put into a Database (SQL).
