I am currently using LINQ to try and display data from SQL server in to the relevant text boxes on an asp.net form using vb.net. However when I run my form in Visual Studio the data is NOT appearing in the text boxes. To give you a better understanding of what I'm trying to do the code is displayed below.
Using my entities As New HEALTHENTITIES1
Dim health = FROM TBLLALTEST_HEALTH In myEntities.TBLLATEST_HEALTH
Where txtName.Text= TBLLATEST_HEALTH.FORENAME + " " + TBLLATEST_HEALTH.MIDNAME
Where txtSurname.Text= TBLLATEST_HEALTH.SURNAME

i am pretty new to asp.net. i have a little bit of MIS background so i understand the basics of programming. I went ahead and purchased an ASP.NET book and i understand everything. Right now i am creating an application for a doctor. I have created the database behind it but my problem is that i dont know how to INSERT data into the databases from textboxes, radiobuttons, checklists etc i know how to query, modify, delete data but i am stuck on how to insert
In the beginning of the deployment the database will be empty since the doctor wont have any patients. Just to give you an idea how it will look, the first text box will ask for the patient's name, the second for their telephone number etc
I am developing a mini project in asp.net-c#..how can i visible number of textboxes at runtime to insert records by single click in sql server 2005. for example. If I have assigned 3 subjects in Assign_Subject table then i want 3 textbox at runtime but when we retrieves the subjects from Assign_Subject table we don't know the exact number of subjects to insert students marks into Exam_Result Table....
I need to create textboxes dynamically as per assigned subjects and also I need to read the text entered later (in my case its marks of the student)then 1 Insert button to insert all subjects marks as per single click.
I have grid view in ASP.Net 3.5. I need to add multiple blank rows in a gridview and then have to save them in database. How can I do that in most simplest way?
View 7 RepliesLet's say I have a dataset in an ASP.NET website (.NET 3.5) with 5 tables, each has roughly 30,000 rows and an average of 12 columns. I want to insert all of the data from the dataset into 5 very-similar-but-not-quite-identical tables in SQL Server 2008. I also want to use LINQ (personal preference - trying to learn something new).
Is it as simple as iterating through the dataset and, for each row, creating a new instance of the associated class, initializing its data with the dataset's row, adding it to the data model, and then doing one giant SubmitChanges at the end?
Are there better ways of doing this with LINQ? Or is this the de-facto standard?
I am trying to insert the data via linq to sql concept. i wrote down the code like this. here customers is the table name in which i want to insert the data. How to achieve it? following code is not working. How to insert the data via this concept.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim context As New linq_to_sql_classesDataContext
Dim custid As New Customer
custid.CustomerID = Trim(txt_custid.Text)
[Code]....
I need to insert large amount of data into SqlServer 2008. My project is based on linq-to-sql.
I process csv file with 100.000 rows. Each row is mapped to Order object. Order contains also collection of Category and Code objects. I need to map each row to object in order to validate it.
Then I need to insert all these objects into database.
List<Order> orders = Import("test.csv");
db.Orders.InsertAllOnSubmit(orders);
db.SubmitChanges();
OR
foreach(Order order in orders)
db.Orders.InsertOnSubmit(order);
db.SubmitChanges();
Both ways are slow. Is there any workaround? I may use other approach than l2sql for this task.
I read about SqlBulkCopy class - would it handle inserting child entities as well?
i have a gridview binded to a database(MySql), with a column ID.now what i want is that when some clicks that ID(Unique) the data corresponding to that ID should be displayed in individual textboxes.

So i currently have a textbox and button to perform the search function...then i want the data fetched to be displayed on several texboxes on the page (say there are 5 texboxes that I need to populate).how this can be done? Here is the code that I have come up with so far. I am stuck in trying to figure out how to bind the data to the textboxes. I also have my connection string in my config file and I have that code below as well..

Salary texbox3
SAVE ButtonThen SAVE button to save data entered in the textboxes to the database. Gridview design to achieve like this.

View 1 RepliesI'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables have a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate.I'm looking for a way to inject the setting of these properties before the objects are inserted and updated.
I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action.
Example: we have different articles in a database like cars, jewelery, boats. The data related to these articles is different in the tables. I have to show that data in a textboxes and let the user change those data and update. I can do the update and reading the data from database. But the problems is for each item the no.of columns and rows will differ.
My task is I need to get the data according to the use selection in the table with textboxes. I dont know which container (gridview, formview or etc) will suites for my requirement. send me any sample code or any tutorial related to this.
Note: showing the data in a table should be a constraint. Because I should show data row wise (each row contains 3 textboxes and 3 labels (DB table column names))

View 1 RepliesI have a basic web form with about 5 textboxes. One Textbox is "Date1" and the other is "Date2."

View 11 RepliesI have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx

Repeater.aspx.cs

Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

I have a one combobox and 3 textboxes and one sql datasource.
When I select the name in the textbox I want to show the values in the relevant textboxes. For instance, in the combobox when i select the Name of the employee the relevant information about this employee is shown in the 3 textboxes, i.e. age, cell #, extension.
I have 5 textboxes in my webpage for entering address, i.e,
door no, village, city, district, pincode.
These are concatenated by comma (,) and stored into the database field address. at the time of retrieving, the concatenated address, should be separated and assign to each textboxes.
