I have two pages: the first it's a gridview that bind to DataSet, the second one have DetailsView that bind to DataSet that is used for editing and inserting.
Upon insertion on DetailsView Page, I want to redirect to GridView Page.

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?
View 7 RepliesI added some textboxes to gridview using following code
<asp:TemplateField HeaderText="STD<br/>ID">
<ItemStyle BackColor="LightBlue" />
<ItemTemplate>
<div style="font-size:xx-small; overflow:hidden;">
<asp:TextBox ID="txtStandard" EnableViewState="true" Height="10" Font-Size="XX-Small" Width="50" Text='<%# bind("STANDARD_ID") %>' runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="AutoCompleteExtenderDemo" runat="server"
TargetControlID="txtStandard" ServiceMethod="GetCompletionList"
MinimumPrefixLength="1" CompletionInterval="1000"
EnableCaching="true" CompletionSetCount="20">
</asp:AutoCompleteExtender>
</div>
</ItemTemplate>
</asp:TemplateField>
I want to save updated values to database, But when I try to access values using string strs = ((TextBox)TwoHeadedGridView1.Rows[0].FindControl("txtStandard")).Text;
It always returns me the blank value for all the rows, Same thing happens for dropdown list it returns me originally selected value i.e. value selected at the time of writing dropdown box, there are no duplicate ids present on my asp form , This is my first interaction with customizing gridview, I want to somehow make it run,
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.
View 7 RepliesGetting 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.

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 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'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.

View 3 RepliesI have been building web apps for a while now and still do not know the answer to this.
I have just built a web app (using webforms) which has a page for inserting a new budget request and a page to edit and manage this budget request.
What is a pain is if I have to make changes to the business logic then I need to edit same / similar code in two places.
What I am thinking of doing is creating one page to handle this with only UPDATE logic and if the URL on page load has no ID parameter then create a blank row in table and use this new ID and then UPDATE.
Is this bad practice? I obv know I need to clear out old blank rows at some point.
is it possible to insert a blank row in gridview when for example a varible changes then there is a blank row then then continues for Eg
Hearders "item" "batch number" "price"
rows apple 1 $1
apple 1 $1
(blank row)
orange 2 $1
is it possible ? & how....fml gridviews

I have a scenario in which the user can add a new option to appear in the list of available choices in a DDL contained in a detailsview when they select an option <Add New>. This displays an AJAX model popup which then allows the user to enter the new option text. Then they hit an Insert button which inserts that new option into the DDL's datasource and I call ddl.DataBind. Subsequently I want to close the modal popup and then display the newly created DDL option as selected.
When I step through the code, everything appears to be working as expected...i.e. the DDL's datasource now has 1 more record than before and the ddl.SelectedValue is the newly created record for its datasource. I can also query ddl.items(99) and see the new option is part of the ddl's items collection and the new record is Selected.
HOWEVER, once the screen comes back from the debugger, the DDL is now showing the newly created option, but still the prior selected option of "<Add New>". And if you pull the DDL down the newly created option is not in the list?
I cannot figure out how that happens...though I suspect it has something to do with the AJAX/Update panel. Here's some code:

Is it possible to code DetailsView to go to the new record I've just insertted? Currently it appears to default to the first record, utlimatly I'd like it sorted Last name, first name and upon an Insert it should go to that new record on pageload.
View 3 RepliesI 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.
