Access :: Possible To Update And Insert From Formview?
Sep 3, 2010
I have a formview where DefaultMode="Insert". Underneath, I have a gridview that displays the information from the inserts. Is there a way to update the information as well as insert? Maybe there is a better way to do what I'm trying to do.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?
protected void gvEvent_SelectedIndexChanged(object sender, EventArgs e) { if (gvEvent.SelectedIndex
I have a web app I'm creating and a form that has a formview control on it. The form's default is set to insert and when the user enters data and clicks save, the data gets saved to the database; only problem is that the form then clears all the data out of the controls.
Upon saving after updating or inserting, I'd like to set the form mode to edit and also have it retain the values they input into the form. I've tried a few things and have not had any luck.
e.g.
Code:
Protected Sub frmCustomerInformation_ItemInserted(sender As Object, e As FormViewInsertedEventArgs) ' Make sure record inserted properly. If e.Exception Is Nothing Then If e.AffectedRows > 0 Then litMessage.Text = "Customer Information saved." 'GETTING THE NEW quoteCustomerInformationId FROM THE SAVED RECORD AND PLACING IT INTO A SESSION VAR.
[Code] ....
What mode does the formview control have by default after it executes the ItemInserted method? Also, what is the prper way to do this?
Am not sure how to go about this... but i have two ddls on a formview which are not related but just insert and update into each other... Both are binded to the objectdata source....
Am issue just came up and i am looking for the simplest way on code behind that would automatically post a constant value (selecteditem) once the first ddl clicks on 1 or 2....
Example is
lst DDL Second ddl
ABC bko
DWC loct
qwe jjjj
Now when ABC is clicked... it should automatically bring out JJJ on the second ddl.... I just want something i can do on code behind.
I am *VERY* new to ASP.net. This may seem simple to you all, but I'm really lost. I have a small sized page with three text boxes (part of the InsertItemTemplate) of a formview, and a slightly modified link the system generated to submit the data to be inserted in the database:
[Code]....
If this page is run, it inserts the data into the database fine, clears the form and sits there. I want it to return a simple "Thank you" page in a window of the same size, with a Close Window buttom at the bottom to close the window:
[Code]....
When I set the postbackurl property on the first page, everything appears to work, except the write is never done to the database. If I remove the postback, it works as it did previously.
I have a page that is using the value from a textbox on a previous page to populate a formview. When I generate the Insert, Update and Delete Statements in Web Developer the edit brings up a blank page and the insert and delete don't work. It works if I just create the formview on a page and hardcode the value in the select statement then the Edit/Delete and Insert works.
I have a listbox inside a formview in a details page(master/details). The values for the listbox will come from a lookup table and when the user select one or more values it should be inserted in a table. The process sould be like the following:
The user will select one or multiple values and click on a Select button. Then a label should show the selected values. Then the user will click on the Insert button in the formview to insert it in the database.
This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then Try If pasDate <= System.DateTime.MinValue Then Return Nothing Else Return CType(pasDate, DateTime) End If Catch ex As NullReferenceException Return Nothing End Try Else Return Nothing End If End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
I have written a script to write several values to an Access Database Table, but I need to ammend i so it checks for two values (Asset and LName) to see if they match if they do it updates the record if not it writes a new record, my script so far is as follows :
[Code]....
I'm just stuck as I can't work out the best way to do it,
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?
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.
<asp:FormView DefaultMode="Edit" ID="FormView1" runat="server" onitemupdating="FormView1_ItemUpdating"> <EditItemTemplate> <asp:TextBox ID="txtPrimerNombreNatural" runat="server" SkinID="texto" MaxLength="30" Text='<%#Bind("PrimerNombre") %>'></asp:TextBox> <asp:TextBox ID="txtSegundoNombreNatural" runat="server" SkinID="texto" MaxLength="30" Text='<%#Bind("SegundoNombre") %>'></asp:TextBox> </EditItemTemplate> </asp:FormView> <asp:Button ID="Actualizar" runat="server" Text="Button" CommandName="Update" /> This formview is bound in this way: protected void Page_Load(object sender, EventArgs e) { Persona _persona = new Persona(); _persona.ObternerPersonaByUserIdApp(1); List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona = new List<SILPA.AccesoDatos.Generico.PersonaIdentity>(); persona.Add(_persona.Identity); FormView1.DataSource = persona; FormView1.DataBind(); }
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) { }
Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
I am having a problem getting the FormView Control in Visual Studio 2010 inserting data into a SQL database I have managed to view the data that is currently in the database but when I click insert I get an error message I just don't understand what I am doing wrong
I have a FormView that is in Insert mode and at page load I assign the current date to a field in the FormView. This works. But after I click Insert, the default date gets cleared out of the FormView and does not come back.I have stepped through the code in debug mode and even though there is a post back and the page load code runs again, the default field is not populated. For one thing, during this postback, the FormView still contains it's field values.
While stepping through in debug mode, the last thing to happen is the InsertTemplate section of the included code, below. After the last text box is referenced within the InsertTemplate, the FormView values go blank and the GridView that it feeds gets a new row. But processing does not come back to the code behine file and the default date field stays blank.I have been trying to find an event that happens after the FormView empites itself of it's values so that I can set the date field the same way I am setting it on page load, but so far nothing works.
I want to Check Gr #(PK) of student wheter exist in table or not id exist show Msg in Label after lost focus from text box .. I tried AutoNumber in Access but it showing error while insertion Note : im using form View control for insertion...
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection OleAdpData.InsertCommand.Connection.Open(); OleAdpData.Update(dtData); // dtData is the datatable OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
