DataGridView Edit Mode?

Jun 28, 2009

This should be something simple, but I just cant make it work. I have a DataGridView with a "Technician" column that I would like to have a dropdown box, allowing the user to select and assign that row to X technician. It works, however with the default edit mode, you have to click the box THREE times to get the dropdown. If the edit mode is changed to "Edit On Enter", it works FIRST click, but this ruins the way I want some of my other columns to work.

Questions:

1. Can I enable/disable editing of ONLY certain columns?
2. Can I set the edit mode for ONE column?
3. My "Unassigned" section (the last line) no longer works after adding my "With" section to add my combobox. I thought the "DataPropertyName" would allow this to work. Whats the deal?
4. Can I edit the visual style of the combo box? It does not match AT ALL

Edit Access DB Through DataGridView?

Apr 17, 2012

I'm familiar with SQL to an extent from PHP, but I've never worked with databases in VB.net before.I'm making a scheduling system to try and learn how to work with databases, and I have an Access database, that is already populated with data, has all the foreign keys and associative tables, that I need to connect to a DataGridView in my Windows Form.This is basically what I need to accomplish:-Have each table of the database display in it's own DataGridView.-Have changes made in the DataGridView/Windows Form in general... actually update the Access database(I would for example, schedule a new course(by clicking new course, and then selecting the appropriate values for each field), and it would check the make sure the student isn't in a class at that time, that the classroom isn't taken already, and the the instructor isn't busy at that time on that day)

How To Edit Data In DataGridView

May 4, 2009

I have a datagridview that is bound to a Dataset I have created. My question is, how hard is it to be able to edit/add data to these rows? It looks as though the Dataset is actually a query of somesort (which you obviously can't edit) Is there a way to link directly to the table for editing? I know you can do this using queries, etc... but I'm thinking there should be an easier way.

DataGridView Add TextBox & And Allow Edit After Binding?

Feb 20, 2012

I have one DataGridView named dgv.dgv is pretty much a plain gridview. No bounded data. No columns added. It's basically empty.I also have one DataTable named dt.I add rows and columns manually into dt.

dt.Columns.Add(New DataColumn("TexBox", GetType(String)))
dr = dt.NewRow()
dr("TextBox") = String.Empty
dt.Rows.Add(dr)

I then simply set dgv datasource into dt.

dgv.DataSource = dt
dgv.Refresh()

I then set the value for this particular cell.

dgv.Item(0,0).Value = "xxx"

Now when I run and execute all those commands. I happen to retrieve the gridview with that value indeed. The "xxx" cell appeared and currently it's uneditable.What I want to achieve is:Allow this "xxx" cell to be editable. Preferrably if it can be inserted into a TextBox control inside the cell.

Edit A Bound Datagridview Programmatically?

Aug 15, 2010

I am using Visual Basic 10/I have 2 datagridview tables. The main datagridview can be edited by the user; adding/removing rows, changing data in text/combo columns, sort, etc. 2 columns from the second datagridview are a carbon copy of 2 columns from the main datagridview. I have achieved this by binding both datagridviews to a dataset. So that when I edit the main datagridview the effects are automatically replicated in the second datagridview.

Before I bound the datagridviews to the dataset I had a fully functional system to save the content of the datagridview to a text file and read it back in. This has now stopped working with the error message 'Can't edit a bound datagridview programmatically'.

Cell And Stay In Edit Mode For .NET DataGridView?

Aug 2, 2010

I have a DataGridView in which one column has data that the user needs to align by adding spaces. For example, the first two rows might contain:

kumbu
kuimbiu

And the user needs to be able to line up the letters that match by adding spaces. Something like this:

ku mb u
kuimbiu

Now in order to do that with the DataGridView, the user must enter edit mode in the top cell, add spaces, hit enter, re-enter edit mode in the bottom cell, and then add spaces. Our users would like to be able to, while in edit mode in the top cell, hit the down arrow and advance to the second cell while staying in edit mode, saving clicks or F2 hits.

Is there a good way to do this? I have tried trapping the down arrow key press, leaving edit mode, advancing a cell, and then entering edit mode with the grid's BeginEdit method, but this does not do what I want.

How To Edit Specific DataGridView Cell From Another Form

Sep 25, 2009

I have a main form with a DataGridView populated from an Access Table.So far so good.When the user clicks on a row a small form pops up and the the user can enter/edit for 2 specific fields .After that hitting the save button an update query ensures that the data are written back.Because the base table is big i don't want to refresh the dataset (at least i don't want to have the user wait for a good amount of time for a simple change.......this is acceptable only when the application is starting) and i thought given the fact that the changed data are just a few words to "edit" the datagridview cell i want so that it displays the changes.BUT i can't do that.As soon as the 2nd form where the user enters the details the DGV from the main form is unaccessible.When i try to get access to it i have a nice message "Reference to a non-shared member requires an object reference."I tried to make a object reference but nothing ...

Not Allowing Null Value In Datagridview When Trying To Cancel An Edit?

Jul 28, 2010

I have a datagridview that has three columns. All three fields are unique fields in the Access table that the datagridview reads from in order to make sure that an entire record is unique. I have a form where a user can add a new record. Upon opening the form, two of the three fields have data automatically entered, leaving one field for the user to enter information. The field that the user needs to enter information in is put in edit mode. The problem I am having is that I have a Cancel button if the user does not want to enter a new record and wants to close the form. I tried using the following line of code to remove the current record that has information in two of the three fields before closing the form:

Programmatically Edit My Datagridview Cell Values?

Mar 15, 2012

I programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.

When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.

Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?
