Forms Data Controls :: Two Ddls On A Formview Which Are Not Related But Just Insert And Update Into Each Other?
Jul 21, 2010
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 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 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 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 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 used to ADO.NET+DataSet many years ago, but now, I need it again. So what I need is to add related rows with tableAdapter.Update method.Here is my code: [Code]....
but I get the "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_Project". The conflict occurred in database "QTracker", table "dbo.Project", column 'ID'. The statement has been terminated." exception at the "qTA.Update(ds);" row. I have seen many examples that do the same, but my code still throws the exception.
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?
Let's say I have a gridview, with 3 dropdownlists, and 1 datepicker(in edit template), and 2 textboxes.When I tried selecting a new value for a dropdownlist, the value would automatically revert back to it's original value, without me clicking on update. May I know how am I going to update the gridview with multiple ddls?
<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) { }
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 am using the query builder to frame an Insert query that I am using for a FormsView control on a web page. The problem is there are more than 50 fields that need to be inserted and I am wondering if there is any better way to do this... than manually typing in IdNames of controls on the web page in the VALUES (,,,,,,,,,,.......) section of the SQL statement.
Formview1 datasource ID is SQLTest. When I click New on the form and go into insertmode, is there an easy way to auto file textboxID to the value of the NextIDNumber field ( field 9) from SQLTest datasource?
I have a formview with insert function into "table1". In that formview i also have a dropdownlist listed with records from "table2". (This dropdown is of course instead of a textbox). get "table1" inserted when one of the field is from a different table?
I have a page with an EntityDataSource and I want to insert a new item using a FormView. However, the SQL database has a varbinary field which I need to insert an image into.
So far, I have all the rest of the FormView correct and it saves no problem. I can also use the asp:FileUpload to correctly obtain the data. I am assumin that I need to add some C# code to the FormView1_ItemInserting Event Handler, but that is where I am stuck. So far, this is what I have:
[Code]....
Would somebody be so kind as to point me in the right direction with the correct code to add this item to the data I am saving.
How do I clear my formview after a record has been inserted or deleted? At the moment it just sits in the previous state with the same details in the fields, still with the Insert button. Either it would be good to drop the formview altogether (I have a grid view on the same page) or move into the edit mode for the just inserted record.
Also the same with the delete - the formview stays on screen with the deleted record details and the delete button still available - I know it has fired though as my gridview is updated.
I have a Formview that allows applications to be inserted into a database. Text boxes such as Name, Address, etc. are bound to the database. I'd like to have the text fields checked for proper case and changed if necessary before writing to the database.
I don't care about notifications, or specialities (such as handling McK..). Looks like the strconv() would work, but I'm not sure how to use it - Still pretty new to using this!
I have a stored procedure and a function. I am connecting my FormView to the function and I am trying to insert a new record. I am not sure if the problem is the stored procedure, the fucntion or the FormView.
My dataset table data is from multiple tables (showing on a gridview),How to update the database tables using batch udpate on clicking submit, if the data is from a signle table, no problem, but I am not sure how to handle if the datais from mulitiple tables? If I have related tables, do I need put them in differet tables in the dataset?
