I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I have a strange problem. I suddenly noticed that the gridviews on my list.aspx page are now displaying the numeric foreign key value rather than the display column value. For example, instead of displaying:

My system is require user to key in data in textbox (above) and then click button to insert values into gridview (below). But I dont know where is the problem.i tried to insert textbox values into gridview..but it failed.
How to display the empty gridview, then insert values to gridview and finally to edit the values (values display back to textbox to update)..
My code:

Dim row As Integer = 4
Dim dt As New DataTable()
Dim dr As DataRow = Nothing
'dt.Columns.Add(New DataColumn("Bil", GetType(String)))

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.

View 1 RepliesI'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?

View 4 RepliesI have a formview on a web page, set to insert mode as default. The form view is bound to a SQLDatasource. This datasource has a custom query written to select the details for this formview. The query joins two tables to provide relevant detail and not just an ID for one of the elements on the form view.
The first tabe contains information regarding projects and the second table contains detail regarding Resources. First table has the following definition:
[Code]....
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?
I'm building a list view that contains a list of message such as FaceBook...I need to keep a textbox to have the text to insert, a label and a imageI tryed:
[Code]....
I have a DetailsView for inserting values and currently the columns are center aligned. What I want is to have my "label" right aligned and my "text box/dropdown box" left aligned.
Something like:
Name: _______________
Address: __________________________
Phone: __________
Insert Cancel
If I change the alignment to left for both, the Insert and Cancel buttons on the bottom of the control also shift to the left, and I'd like them to stay centered.
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.
