VS 2010 Edit - Click To Commit The Changes To The Loaded Items In The Datagrid
May 29, 2011
I have an application that saves details to then be viewed in a datagridview on another form. Clicking on an entry in the datagrid (I want to make this double-click, but haven't bothered to try yet) highlights the row, and loads the values to a new form, in read-only text boxes. Clicking Edit changes the read-only value of these text boxes and allows you to edit (obviously) the contents. I have another button, Save which I want to click to commit the changes to the loaded items in the datagrid.

Using the walkthrough from [URL], I implemented a DatagridView in virtual mode, totally unbound, in VB 10 Express (we are talking WinForms).
I understand that CommitEdit (DataGridViewDataErrorContexts.Commit) commits the current cell's contents to the data cache.
The example uses row-level commit, i.e. it pushes the values into a row buffer until the current row is left. Only then the row is added to (or updated in) the data store. That's exactly what I do, too.
Question -- how can I commit the current row programmatically without leaving it? (I want to commit the whole row, not just the current cell.)
If the user leaves the row, there is a RowValidating, RowValidated, RowEnter event sequence where the datastore update is taken care of. So one idea (currently my only one) was to simply re-set CurrentCell to Nothing, for example.
But I cannot just set the DataGridView's CurrentCell property to Nothing (or any cell outside of the current row) since I want to commit from within an event handler of a custom edit control created by a custom column, and I see an System.InvalidOperationException exception when setting CurrentCell there.
In fact, it is a tiny button right to a combo box, i.e. I create a DataGridViewComboBoxCell descendant which is a DataGridViewComboBoxColumn descendant's edit control. My special ComboBox cell adds a tiny button which should commit the current row. Unfortunately, that button's _Click event handler cannot change CurrentCell since DetachEditingControl throws the exception then.
Obviously, I must delay the CurrentCell re-assignment until the whole _Click event has been processed. Or what? How would I do that -- register a custom Windows message, SendMessage that one to me, and override the windows procedure of the form so it re-sets CurrentCell when this message is received? (Hello?)
There should be a rather easy way to let DataGridView commit all changes by firing the events that I handle to perform the datastore update, no?

so I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form

I have two Windows 7 machines and for some reason one of them does not save the changes in the file on the local computer when I right click in the WebBrowser and choose View Source.
When I click on View Source in the WebBrowser, it opens the file but with [1] attached to the filename.
When I edit the Source, and save it and reload the webbrowser,the changes not saved.

I have
- system.windows.forms.timer with a 20 second interval
- it checks the status of a website using HttpWebResponse
- I have a datagridview with a column that holds the website(s) name
- Once the timer gets the results its places the results in another column on the datagridview
- a for loop will loop through the column that holds the websites name and posts the results for each row/website.
If all the sites are up and running it works fine. If a site is down HttpWebResponse takes about 10 seconds to return the reason why and the program can not be used during that time. So I read up on timers and realized there were 3 kind. The System.Timers.Timer sounded like a better solution since it runs on a worker thread. This sounds perfect since the user can still use the GUI without waiting for the timer to realize the site is down.The problem I have is if i tried to get the row count of the datagridview so I can loop through the sites messagebox. show (frmMain. dgvMonitoredSites.Rows.Count - 1) it will always return 0 even if there are over 10 rows. It's almost as if it's looking at a datagridview in another instance. Is there anyway I can get this system.timer to see the items in the datagrid?

I'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).

I have software which is loading texts from files in folder, also if user wants to click on link he just using "click" button and it will search it for him and will open in built in browser. Thing is that some of those texts has just [URL] instead <a href.... a>
At this moment I'm using this:
For Each link As HtmlElement In webMail.Document.Links
WebBrowser1.Navigate(link.GetAttribute("href"))
Next
But I'd like to to be able to click every link with just http in text, no matter if <a href is in use. I guess I can just add <a href to any http string but I guess there must be other way to do that. Should I some how look for any string with http and then just set it as variable and then navigate or can I use other way? So for now I have 2 ideas, one replace http://... with <a href... a>, or to find any string with http and set it as variable and then navigate to that web browser...

I have a small application. When I click on a ListView row to Edit the details populated from the MS Access DB, I have the Else statement being executed all the time. Initially the code is attached behind a button named Edit. I have a Refresh button also which is clicked before the Edit button is clicked. Thus I just don't want to click on the OK button on the message box generated from the Else part. I just want to switch the Edit option between the ListView data when the ListView is item is clicked.[code]...

I would like to show different values in a dropdownlist, while editing a gridview, depending on which user is logged in. For example...
The officer would see "Approved by Officer" status.
The director would see "Approved by Director" status
I am trying to add these programatically to a dropdownlist which I have in the edit template of my gridview (approvalsGrid). Here is my code:
Protected Sub ApprovalsGrid_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles ApprovalsGrid.RowUpdating
Dim ApprovalEditDD As DropDownList = CType(ApprovalsGrid.Rows(ApprovalsGrid.EditIndex).FindControl("ApprovalEdit"), DropDownList)
[code]....
I do not get any errors. But get an empty dropdown with no items. Am I using the correct event?

Using Visual Basic in Visual Studio 2008, I have created a Windows form with multiple tabs and questions. Each question has an associated drop-down listbox that the user will eventually click on to enter his or her response. My client has now informed me that she wants to change the standard responses in each response box. There are well over 100 drop-down listboxes, all with the same items, and they all must be changed.
I originally inputted the items using design view. Would someone please tell me if it's possible to edit all of these boxes in the design view simultaneously? When I control + click on more than one box, the Edit Items option that is normally available disappears. Is there a way to do it in code in a manner that would save back into design view?

I have an app where i have two list views
[Code]...
I clone the information to the empty listview2 from populated listview1 adding quantity via a numeric up/down. That works to a certain extent but problem is it adds another instance of the added item each time I press buy. I would like the items to appear in listview2 according to their index value in listview1. And when I press buy the app change only the quantity in column 2 if the item is already in listview2, if not just add the new item.

In my project, I want to use Coordinates of a place (eg; London) which is selected from a list of several thousands of coordinates of places.
I thought of using comboBox / ListBox to display the list of the coordinates of places.
I want to know how to make this "editable"; ie: anyone using this program should be able to Edit / Add / Delete a coordinates of a place. And the newly added Place should be saved so that he/she can use it whenever it is needed.

I'm working on a Visual Basic application in Visual Studio 2010. The application was originally created in VB6, which had a dedicated menu button editor. Now I need to add new drop-down items to my button menus, but VS10 seems to have no facility for this. All attempts so far appear to lead me to tool strip support, which I do not want.

I have an application that loads a web page then allows the user to edit that page by setting the Webbrowser control to EditMode.What I am trying, so far unsuccessfully, to do is trap when a user right clicks on a link already on the web page. The problem I have is that although I can trap the right click using MouseDown and GetElementFromPoint, if the link that is clicked is nested within a higher level element then the higher level element is returned by GetElementFromPoint not the nested element.[code]When the user right clicks, say, the link with test2.html my current code returns the DIV element not the A element. How can I understand which of the A elements the user clicked.[code]
