Forms Data Controls :: SqlDataSet Not Submitting Anything On Insert?
Jun 11, 2010
I have a SqlDataSet connected to a FormView with a stored procedure for the InsertQuery. The SP has an InputOutput parameter and about 8 other standard input parameters.I referesh the parameters etc., and when I run the app and post the insert NOTHING happens. Well actually all of the insert events fire and the FormView goes to ReadOnly mode like its supposed to, but nothing is sent to the SQL server.
I'm running SQL Profiler and can see that literlaly nothing is happening.However, if I change the SP to just a regular query and just put some random query (like SELECT * FROM TEST), then when I do the insert the query does get passed to the server, along with parameters for all of the fields (even though I haven't created any parameters, due to the fact that I'm using bound controls I assume).
One thing about the SP I'm trying to use is that the names of the parameters are the same as the column names for the fields to be passed to them, I'm wondering if this is an issue, i.e. spAddUser @name = @name, @email= @email, etc?I wonder this because I've also tried just using the SP as a Query, instead of an SP, doing EXEC spExample @param1 = @param1, etc, and that doens't work either. In that case it also sends nothing to the server as well.
I have a web form on which the user fills in a basic data: date (with drop down lists), an asset class (with a radioButtonList that is bound with en Enum) and other simple controls... The, when the form is submitted, I make a query on the database to retrieve my data and bind these data into a gridView.
The 1st time I submit the form everything is working well, the second time even if I change nothing in in the web form, the GridView1_RowCreated fires an exception when the property AssetClass is called. The error message is
Must specify valid information for parsing in the string.
This is because rblAssetClass.SelectedValue is empty, but I don't understand why.
I have a problem with DetailsView linked with Database, DetailsView is Insert/Edit enabled, and adding/ediditng data works, however........ when I add a new record (DetailsView in Insert mode) and press INSET instead going to record I have just created in Read-Only Mode it shows me blank form, it looks that the "linking" field is null.
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.
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?
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
I'm quite confused about how to implement a many-to-many relationship and my domain model. Let's say I'm creating a recipe box web application and I have three tables called Category (categoryID, categoryName), RecipeCategory (categoryID, recipeID), and Recipes (recipeID, recipeName, recipeDescription). If I were to present this information as an ASP.NET application and wanted to insert a new recipe and category, am I responsible for writing the logic to insert the information in the RecipeCategory table OR is it possible to set RecipeCategory.categoryID and RecipeCategory.recipeID automatically with default values based on newly inserted records in the related tables? If I'm responsible for writing the logic to insert values in RecipeCategory.categoryID and RecipeCategory.recipeID is that a trigger? What's the best way of implementing this?
I have a GridView (BulkEditGridView), that has 10 rows from the datasource. I Add a TemplateField "Insert Row" button to insert 1 blank row at selected row using Rows.AddAt.First time i press "Insert Row", it works as expected, the row inserted at selected row. now i press another "Insert Row", the row is inserted, however the row (in first time inserted) now move to the last row. and so on.
Suppose the form is to be submitted to Controller: Product, Action: Add. What sort of coding techniques can I use to handle this dynamic form, such that I follow good or best practice, and if possible also be elegant.
The solution I see so far is to test the Request.Form (or Formcollection) indexer/dictionary for existence for the dynamic input fields. E.g.
public ActionResult Add(Formcollection form) { int productEntry = 1; string productPrefix = "Product"; while(true) {........
I have used Expression Web to create a website with a standard .ASP form that saves data into an Access database using standard HTML controls. This works fine except there is no validation of the fields. A user can enter anything to get past the form.
I want to use ASP.NET to validate all of the fields in the form and then save to the same Access database. When I rename the webpage from .ASP to .ASPX, I am able to get the validation controls working properly by changing HTML controls to ASP.NET controls.
However, I cannot figure out how to get the form data submitted into the Access database because the code to connect to the database was removed when I inserted the first ASP.NET control.
What am I missing? It seems like a simple task but I haven't been able to figure it out. I have a couple books and they don't answer the question. Can someone guide me in the right direction?
I have a form that contains a number of user controls (partial views, as in System.Web.Mvc.ViewUserControl), each with their own view models, and some of those user controls have nested user controls within them. I intended to reuse these user controls so I built up the form using a hierarchy in this way and pass the form a parent view model that contains all the user controls' view models within it.For example:
Parent Page (with form and ParentViewModel) -->ChildControl1 (uses ViewModel1 which is passed from ParentViewModel.ViewModel1 property) -->ChildControl2 (uses ViewModel2 which is passed from ParentViewModel.ViewModel2 property) -->ChildControl3 (uses ViewModel3 which is passed from ViewModel2.ViewModel3 property)
My question is how do I retrieve the view data when the form is submitted? It seems the view data cannot bind to the ParentViewModel:public string Save(ParentViewModel viewData)...
as viewData.ViewModel1 and viewData.ViewModel2 are always null. Is there a way I can perform a custom binding?
Ultimately I need the form to be able to cope with a dynamic number of user controls and perform an asynchronous submission without postback. I'll cross those bridges when I come to them but I mention it now so any answer won't preclude this functionality.
On my web pages I display the data as mm/dd/yyyy and that is how the user will enter the dates as well. But when I pass the textbox control that has the date in it as a parameter to the SQLDataSource control, I need it to be sent in the YYYY-MM-DD format for the AS400. Is there a way it can be changed in between?
I am trying to create a website that takes input from users and then updates a table in MS Access db. I have a plain html form that takes the imput and in the action I entered the asp file name. Once a user clicks on submit on the html page I get the 500 internal server error. I properly uploaded the files on the server,
I have created a DSN on the server, but cannot see the DSN under the "Select ODBC DSN" when I try to create a connection from DreamWeaver. I am using a 64 bit machine so nto sure if that might be causing the problem. Here is code form asp file :
<% @ Language="VBScript" %> <% Option Explicit %> <html> <head> <title>Form to database</title> </head> <body> <% 'declare your variables Dim name, email, comments Dim sConnString, connection, sSQL ' Receiving values from Form, assign the values entered to variables name = Request.Form("name") email = Request.Form("email") comments =Request.Form("comments") 'declare SQL statement that will query the database sSQL = "INSERT into users_tbl (name, email, comments) values ('" & _ name & "', '" & email & "', '" & comments & "')" 'define the connection string, specify database 'driver and the location of database sConnString=("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='d:/hosting/6859771/html/access_db/Users.mdb';User Id=;Password=") 'create an ADO connection object Set connection = Server.CreateObject("ADODB.Connection") 'Open the connection to the database connection.Open(sConnString) 'execute the SQL connection.execute(sSQL) ' Done. Close the connection object connection.Close Set connection = Nothing response.write "The form information was inserted successfully." %> </body> </html>
I am working on a page where the user first selects a state from a drop down, then a city from a checkbox list (eventually able to select multiple cities, but have to figure out how to do one first). The checkbox list is dependent upon the state selected. I would like the selected value of the checkbox to be submitted into the ListingLocation table of the database. In the code I have written I have included a label that displays the id value of the selected box when submitted just to make sure that the checkbox is providing the correct value. For some reason when I select a state and then check a city and click submit, no value is written into the database. The label text changes to the number I want entered into the database, so it is generating the correct number, but not submitting. I have included my code below.
there is a textbox and button control. On button click event content of textbox is submitted to database and javascript alert is displayed. Now the problem is- If I am refreshing the page using F5 then same value of textbox is being submitted into database and javascript alert is coming again.

OK, I have exhausted myself troubleshooting this bug. The crazy thing is, I think I had it working months ago, and now it does not. All I want to do is submit FrmCart when the "Update Total" link is clicked. Below is the code.
