I only need one textbox inside gridview and other operational buttons like add , edit , delete in gridview. I just need that these buttons can save the data in datatable like we do :
DataTable dt = new Datatable();
I don't want to save it in database at this stage. CRUD Operations using datatable inside gridview is my aim.

I have some questions: becase all of entites need to have CRUD operations, so i want to have a master page with Insert, Edit, Deleter Button and a place holder for entity form, so for each entity i create a form with this master and create textboxes and label in asp:content tag.for this to be done i konw master must have a Interface to do operations. so i wanted to define ISchoolSystemRepository<??> as a property in master page, but i must pass it T which will determined in runtime. so

View 1 RepliesI have a simple add form on the page and below it is its gridview with edit and delete buttons. Everything works fine, but when i click on edit on a particular row/record, it changes to edit row but i want the record to be edited in the original add form (which is above the gridview).
I am able to edit a record on the gridview but i want it to be edited in the add form. Is there any particular way to do this? I came across formview concept but not sure if i am able to do that with it.
Below is the form and gridview code.

I need a bit of help with a scenario. I am working on a web application that requires huge amounts of data to be Added, Deleted, and Updated. The data entry forms are divided into logical groups through Multiviews. All the information is saved when the mighty Finish button is pressed. The current setup (previous developer) does not allow me to use transactions. Therefore, if I am to save a new Courier to the database, I need to add his/her Distance and Rate info. In addition, I need to add his/her Banned Areas info (Area Name, Post Code).This is where it gets interesting. Obviously, the DistamceAndRate table and the BannedArea table in my SQL Server will have the CourierID as a foreign key. Since I'm going to save the Courier as well as the Rates and Areas info in one go, I cannot have the newly created CourierID before. Therefore, I cannot bind my Grids for Distance + Rates and Banned Areas directly to database.What I am doing is creating two DataTables and managing them in Viewstate through properties as follow:
[Code]....
So, on page load, the DataTables are initialized with a blank schema. Here are the attempted CRUD implementations (Distance and Rate only):
[Code]....
I am having issues when I am canceling a new entry and when I am editing a new entry. In addition, for Distance and Rates, Rate is acting as unique (cannot be repeated) and attempting to control that is also giving me a headache. I end up creating blank rows.And here's the ASPX cut-out:
[Code]....
Hope to get an answer soon.Also, off-topic, I'm using LINQ here. In order to save a Courier and his/her extra details, I first save his/her address to DB. Then I take the ID of the address and save the courier. now the courier ID is avaliable and i start filling extra tables related with the courier table. If something goes wrong, I have to manually delete created rows. LINQ uses transaction internally but only until a SubmitChanges() call. I'm forced to save each entity so I keep calling SubmitChanges().I tried manual transaction but after saving the address inside a transaction, the Address.OID (Address table's mapped prime-key) had a 0. attempting to use this newly added address while saving Courier in the same transaction threw an exception. If there is a way to get the primary key for entities created in a transaction that is yet to be commited, please mention that'll as well.
i am displaying a gridview from db(SQL2005), which display leave table where employee apply leave and submit to admin. Viewing the leave table in gridview the admin sanction or rejected their leave request, by clicking the check box displays on each gridview rows and click on sanction or rejected button.
here i am sending SMS to the employee number displaying in the gridview (taking the employee phone number and send SMS).. this i have done using bulk SMS services, i have taken the number using the following
if check conditions...
but now what the problem is i have to delete the gridview rows.. i am using the same employee phonenumber to delete the corresponding gridview, but if suppose the single employee applied for two or more leave, the gridview display all leave for the single employee, the admin have sanction only one leave for that employee.. so if he checks the check box and click on OK button.. it have to delete the corresponding row as well as send SMS to the phonenumber of the employee.. Other leaves of the same employee display in the gridview.. i used the following coding
Protected Sub bttnsanction_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bttnsanction.Click
Dim row As GridViewRow
Dim selection As New ArrayList()
For i As Integer = 0 To GridView1.Rows.Count - 1.........
I am using the Sno as primary key in leave table.. where i want to delete the corresponding row which sends SMS to employee number also the delete the row of corresponding Sno.. i have to get the corresponding gridview row sno in the delete store procedure..
I have placed Chekc box in Gridview when i select the check box can perform 2 operations simultaniously one is entire recordset is populated into form fileds and second one is can delete the selected record permanently from database table.following code for this fuctionality.

I want to ask that what happens when I make a database request (using Linq-To-Sql). Active thread is blocked and waits for response, or it is used to process other requests?
Do frameworks like Linq-To-Sql or Linq-To-Entities handle this?
If I use Sleep() method on thread, is that thread blocked or is it used to process other requests?
According to the msdn documentation, as you can see on the diagram, a server control's "Data binding events" occurs after all "control changed events". So in the case of a DetailsView control, the ItemInserted event would happen before the database operation?

View 1 Repliesthe best practice for a designing a simple CRUD application with some screens updating various tables (like admin pages to maintain static data for an application). the simplest way would be to drag a data grid/gridview, bind it to a dataset and use a data adapter for CRUD operations. but if this application needs to be scalable, lets say to add any extra UI/business logic in future, then is there any design pattern that can with this? should I be using an object data source control and bind it to business objects instead? or are there any better ways of doing it? should I build a complete layered application or will that be overengineering for this requirement?
View 3 RepliesI want to make sure I go about this in an efficient manner. I have a gridview. On the gridview, I have some columns that are read only values . These values go through calculations based on values in a database. The stored procedure takes information in the database, does some simply calculations (this value * that value / another value type of stuff) then returns a recordset as a datasource for the grid.
Other columns on the gridview have values the users can enter data. I want to be able to provide a recalculate button that will run calculations based on the entered values which will change the readonly values and then repopulate the gridview's read only values without going back to the database. This recalculate button is not the save to the database button. The save to the database button will take the values in the user entered columns and save them to the database. Then, the next time the grid is called, the page calls to the database and loads the grid.
So, what I'm looking to do is allows for recalculations on a gridview, a gridview with about 24 columns and about 1000 rows. My first thought is to create a class that reads the gridview and then applies the business rules, then updates the gridview some how. Or, maybe have a dataset table thats i read the value from the user inputs, then apply business rules and then bind the gridview to the dataset table. Do any of you have thoughts here, maybe have done something like this?
