View 5 RepliesI am running into a problem where my CRUD operations on an entity sourced from an SQL View is not calling the generated methods for said operations.I press "Delete" in a ListView on an item, connected to a LinqDataSource. It throws an error saying that it cannot perform the operation because it affects multiple base tables. That's fine, I understand that. What I don't understand is why this code won't run on insert/delete:[code]In debug, it won't break on the method, so it's not being called. I even did a test where I deleted the entity by attaching/DeleteOnSubmit and still no-go. Is this a bug or am I not handling the right method? I can handle a data source's OnDeleting event, cancel, etc. (which is my temporary fix) but I'd really like to catch ALL delete operations in a central place no matter how I delete the entity.
View 1 Repliesa friend of mine wants to create a simple inventory database that can be deployed on the web.He has had a lot of experience with Database tools like Paradox. Moreover he has experience with writing Macros and programs with Basic, and even a bit of C++ experience. He uses Windows and Mac OS X, though mostly Windows.
If the requirement of having a web application wasn't there I would recommend MS Access.

So I'm developing an application in VB2010. The idea is to perform CRUD operations (more or less) to an Access2003 Database. The database is relational, yet I haven't grasped the best architecture to make an application to interact with it. I tough doing a Business layer with a domain model would work. Controllers for each Use case (which are basically CRUD operations) would create Domain Layer object. Yet I don't know yet how to manage the mapping of the objects to/from the database.

I am using VB.NET 2008 My DataGridView is bound to a DataSet. After adding a DataGridView row (from another form), I needed to sort the DataGridView in order to put the new row in the appropriate place. I needed to be able to identify the current sort column and the current sort direction (ascending/descending) but I was unable to find out how to obtain that information from the DataGridView properties. Consequently I had to do it the hard way via my own coding. The sort column name (or names) and the sort direction then became available to my program in the global variables.

Basically I have a datagridview that holds data. All I want to do is have the user type in a string to an inputbox then search the datagridview for what the user typed in.This is what I have so far really I think the only thing I need is the piece after if dgbcollectionitem.(i need what goes here). after that I'll use an else statement for error checking.[code]

View 5 RepliesProbably I am asking something stupid. I have a datagridview in which I would like to be able to let the user change values of multiple columns by entering values (input 55.0) or additions(input +1.2)/decreases(input -1.2).How can I check what the exact input of the user is ?
At the moment I only use the input value (so for exampel 55.0) for which I use the DataGridView1.CurrentCell.Value which I put in all selected cells, but I would like to receive the exact user input (so eg '+1.2')

View 1 RepliesI have a datagridview that contains a long piclist. The requirement from the user is that they want to be able to type the first few numbers of an item in the list and have the grid automatically scroll to the appropriate spot in the list.I was hoping to find a property on the dgv for it, but haven't found anything yet.
View 3 RepliesI have a datagridview and the user wishes to key some text in a text box and press a find button.The text to be looked for could exist in any columns in the grid (I want to exclude hidden columns).The search is to start at the row the user is currently at. If it gets to the bottom of the grid and still not found the the search would start from the first row of data.
If a match is found then the row with a matching value is to be highlighted.I've looked at using the position and find properties of my binding source but I think this will only let me find on one column and only from the top?Do I need to programmatically loop through the rows in the datagridview and search for the text or may there be a better method?

How to find the seleted row index of datagridview
View 1 Repliesfind the underlying DataGridView (DGV) when responding to a Right Click on a ToolStripMenu (TSM).I have several DGV's all using the same ContextMenuStrip (CMS) [DGV.ContextMenuStrip=CMS]I have six ToolStripMenuItems under the CMS. I thought I could just add a unique handler for each of the ToolStripMenuItems and be a happy camper on each Right Click...But I cannot figure a way to decode the underlying DGV. There doesn't seem to be any relationships between DGV and TSM and none between CMS and TSM.Is this path a dead end? If so how should one do it? FYI my DGV data is unbounded.
View 7 RepliesI have a datagrid view with 3 columns and variable rows. I have many rows so it is tough to know what is where so, the first row consists of names.I have a textbox in which I type in a name and hit a button. Doing this, I want the location of the that cell in terms of row.no and column.no.
Extended : for the adjacent ones just add +1, +2 etc to the column number right ?
I have been using this code to find the value of the cell in a datagrid view
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
MessageBox.Show(dgv.Item(0, eRow).Value)
This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
I have a DataGridView with 3 columns (metric_key, metric_name, metric_value).There are for example, 6 ROWS in this table (6 different metrics), added programmatically (DGV is not bound in any way)
Now, when I assign values in my grid I do:
dataGridView1.item("Metric_value",0).value = "value of the metric in row 0, in the column named "metric_Value".
