Using LINQ To Display Data From SQL Server Into Textboxes On Forms
Sep 25, 2013
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
Where txtPrevSurname.Text= TBLLATEST_HEALTH.PREVIOUSSURNAME
[Code] ....
I would like to see the details for one person to appear and then be able to click a button which would let me to view the next persons details. The version of Visual Studio I am using is 2010.

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.
ie
1 Alok 25 9899898989 India
now what i want is if someone clicks 1 then all data should be displayed in databoxes assigned to all fields.
I am trying to create a page that will display data from a database after a search action by the user. 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..
I 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
[Code]....

Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.
I need to display a list of products 1 below each other with a textbox, i will also need a checkbox that will hold the prodID. so i was thinking i need to do a loop but i am not sure how to do it. It needs to be like this
[checkbox(which will contain the prodID)] prodName Qty [textbox1] [textbox2]
so for each product in my products table i want to display it like above, now this is for a stock take module so the client will enter his values for each product in textbox1, when the client clicks the submit button, i will need to loop through the above products and calculate the difference if any so it will be (QTY - TEXTBOX1), if there is a difference the check the checkbox and display the difference in TEXTBOX2. so if the QTY = 10 and the client entered 8 in textbox1 then textbox2 should show you 2 and the checkbox should be checked. then the client will click the update button and it will loop through every product above and where the checkbox is checked, it should update the QTY of that product from the value entered in textbox1.
I'm new to asp.net, and I'm creating an http website in visual basic asp.net. But when I add a button and textbox it won't display. I don't know why is their a step I have to do in order for the textbox to display. Also I added an image too but It won't display. Its strange.
I am using this code which works perfect when I type username and the studentid in my textboxes in the first page.Now after pressing the button to go to the second page , the two labels display the values of the textboxes in the first page BUT when I am pressing a button in my second page I get this error :
Object reference not set to an instance of an object.
My code which is in the second page load event is :
I use article Implement Paging in DataList control in ASP.Net. Now I want other method. Display Records as First-Next-Previous-Last in a Textboxes Using Asp.Net. How I can convert this code to Asp.Net?
public Form1() { InitializeComponent(); GetData();
I have various ASPX input forms, using tables, with lots of 28px-wide textboxes arranged in columns. They look perfect in IE7 and IE8 but in Firefox, Google Chrome and Opera the textboxes display approximately 5 times as wide, resulting in text wrapping and generally screwing up the nice appearance of the forms. Very irritating after all the work I did to make them look professional in IE8!
Is there a way of coding the forms to stop this happening amd make them look more or less identical in all the major browsers?
I have to display records from two tables where foreign key table contains many values for a primary key column how to get the data using linq query???
my problem is that i have a dynamic controls(text boxes) that are generated depending on a dropdownlist
and upon generating the textboxes i have created a required field validator and associated it to the text box that is being generated,
when javascript is enabled in my browser, the client side validation works fine, but when i disable the javascript.. no server side validation occurs and the Page.IsValid gives true when the method Page.validate() is fired
i tried a new simple page with dynamic controls and seems to work fine, but i could not figure out whats wrong with this page.
private void generateFarmForm() { int numberOfFields = 9; Label[] labels = new Label[numberOfFields]; TextBox[] farmt = new TextBox[numberOfFields];
[Code]....
also the button that submits the form back has the same validation group,,, yet no luck with this... the page is in a content tag of a master page if this has any relation to the problem
I have placed a textbox, dropdownlist and command button in a section of my master page. The textbox, named txtsearch, will be used to input a search string. The dropdownlist, named ddlsearch, will be used to specify in which field to search in the table, either part name or NSN.
Questions:
What VB code do I use to save the value entered into txtsearch as a search string? How do I pass that value to my entitydatasource? How do I tell entitydatasource to search in either the part name or NSN field based on the value of ddlsearch?
I'm having a problem with the results of a Gridview. The SQL statement I use works in SQL Management Studio, but in my .NET app, it only display a few of the results. The part of the SQL that seems to be effecting it is in the where statement I use like:

@Consultant comes from the value of a selected dropdown.
