Forms Data Controls :: Can't Insert From A Dropdownlist Within A Detailsview?
Oct 18, 2010
I figure that this should be relatively straightforward, but I still can't get it to work. I have a gridview and a detailsview to set up shifts for students and teachers. I would like to be able to insert new shifts using a detailsview. I will limit the students, teachers and location to items that are in a dropdownlist. The problem is that when I handle the iteminserting event. the e.values collection doesn't contain all of the fields I want to populate. How do I add the new fields to the list. This is my codebehind:
Sub On_Inserting(ByVal sender As Object, ByVal e As DetailsViewInsertEventArgs)

I have a dropdownlist in the edititemtemplate of a detailsview. The dropdownlist is bound with an objectdatasource. The detailsview is bound to a seperate objectdatasource which connects it to the insert method. When the page loads the dropdownlist is bound properly. However, when I make a selection and select insert I get the following error: Could not find a property named 'DeptID' on the type specified by the DataObjectTypeName property in ObjectDataSource 'objCurrentProduct'. I've tried to remove the SelectedValue='<%# Bind("DeptID") %> attribute. I can then insert without an exception being thrown but the selected value of the dropdown is not recognized. Here is the code:

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 am using DetailsView to INSERT new records. I have a field "Paid Date"(date) that needs to be pre-populated with the current date. 90% of the time, the user will use the default date, however, there are times when the user will need to change the data as needed. I want to add this default in the code-behind. I DO NOT want to use template item.

Scenario : I have two database tables with one to many relationship. eg:- City and Related news. So I have a gridview(Gridview1) which lists out all the cities and allows edit, delete of the gridview rows. Now since i wanted to display all news for the city, i have a nested gridview as a column in this Gridview1. This nested gridview displays all the news for the cities. And I have edit, delete buttons for this gridview too - So far, good - works fine.
Now what I would like to do is - To insert a new news item for a city. For this, I attached a detailsview to my nested grid(gridview2), and tried to insert. I need the primary key id of city table from the first grid (gridview1) to insert the news into the second database table and I could not access this value from the parent gridview. My gridview1 does not have datakeyname, it is programatically bound.
Also, When the gridview/detailsview is nested, it does not get listed in the event-handler list. So I cannot use say, detailsview1_iteminserting. I do not how to add this event handler
Has anybody done anything similar? When I started, it looked like a pretty straightforward thing - There must be some way to do this. But I just can't get it to work. How do you usually insert into the child table in a one-to-many relationship? Should i just be using two separate gridviews?

I'm inserting data into a SQL database through a detailsview. When a user inserts an incorrect data type or leaves a required field blank it shoots off to a big error screen. Is there a control that I can use that will allow it to give an error (with a little star or something) that says which field is incorrect without the big error screen?

How do I set the value of a field in a detailsview to the selectedvalue of a gridview on the same page? I am also trying to set today date as value of another field in the detailsview as well as UserID. I wrote the following codebehind for the date setting:
TextBox tb = (TextBox)DetailsView2.FindControl("TextBoxCreDate");
tb.Text=System.DateTime.Now.ToShortDateString();
TextBoxCreDate is a template field in my DetailsView.
Unfortunately, I get a Object reference not set to an instance of an object. Error message.

My web form contains a detailsview control that I have added a templated field to with a DropDownList in the InsertItemTemplate. The DetailsView default mode is 'insert. My detailsview is attached to a sqldatasource that has a stored procedure in the db to handle the insert. When I enter data in the fields and select insert all values from the detailsview are written to the table except for the selection that was made in the dropdownlist. I am using the ddl.selecteditem.value to populate my variable however when the insert method is envoked it doesn't send my value. The DDL value that I am capturing does not need to be written to the table it is just a flag for some variables that need to be set at the stored proc level. How do I get the DDL selected value to be sent with the insert statement?
Here is my code behind:
Protected
Sub
DropDownList1_SelectedIndexChanged(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Dim temp
As DropDownList
Dim AccessLevel
As
String
temp = AddUserDetailsView.FindControl("DropDownList1")End
Sub
AccessLevel = temp.SelectedItem.Value
Label1.Text = AccessLevel

I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
Where do I put the logic and what am I missing?

This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.

A TemplateField of a DetailsView can be assigned a value easily at any of many event handlers such as Load, PreRender, etc. when the page is loaded. However, after Insert or Cancel is clicked, all the fields are cleared. I cannot figure out how to assign a value to the field again in code-behind.

I wonder if there is a clevcer way of setting the correct page of a DetailsView after inserting new data? I have a DetailsView bound to a LinqDataSoure. Now, if I use this DetailsView to insert new data, everything works fine, except the fact that the DetailsView switches back to the "old" page index after leaving InsertMode.
This is somehow understandable, because it can't know which index the new entry will have, but unfortunately neither do I. So I was looking to the LinqDataSource_Inserted event where I can get the new Entry, but because the DetailsView.SelectedValue is read only, I can't just set it to the new entry. So. I might have to use the PageIndex property, but then I would need to know the index of the new Item, which I don't have either.
So, my only idea know is to store some information from the new entry, wait until everythings bound again, loop through the DetailsView to find my new entry an set it's index for PageIndex. But also here I have two problems:
1) The new entry (e.Result from LinqDataSource_Inserted) has not yet filled it's primary key, as this is of course created in the DB, so it's very difficult to identify the new entry properly
2) I don't know how to access each DetailsView page information without actually making it the active page.
So, my question, is there a clever way of doing this? In the past, I've been using SqlDataSource. Although the problem is basically the same, I could solve the two major problems by 1) Insert with Stored procedure which gives the new primary key back and 2) run through
"(((System.Data.DataRowView)MyDetailsView.DataItem).DataView.Table.Rows[i].ItemArray[0])"
to compare the keys. Both I can't get to work with LinqDataSource.
