I'm currently developing a application in VB.Net. I'm using the DataGridView to display my data on the form. I have a EDIT button on the module and I need to know how can I populate a selected row record into the textboxes from the DataGridView.
View 2 RepliesI have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.
View 1 RepliesAny way that I can set the value of a particular field (let's say a name) on a particular record without having to have the data presented on the forum? Syntax would be along the lines of "Go record "12" and set "Callum Kerr" on field #name"?

Working on Access 2007 and Visual Studio 2008, i already connected my database to the application and can see the data on datagrids and can add or edit or delete records, the problem is that those changes do not go to the database, so when i close and reopen the application, i found the old data as it was before. Note: i used the wizard to add the connection, not the code.

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

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)

I have a datagridview (datagridview1) on my form and it is not linked to any database. I'm only trying to programatically enter values into the rows of the grid by values that my program generates.
For example if the value that my program generates is x, y, z then I would like to say something like[code]...

View 2 RepliesI 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.
View 2 RepliesI 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.
When the cell is selected but not open for editing a right click will open the ContextMenu. If the cell is open in edit mode a differnt list is displayed (cut, copy, paste, etc.). Is there a way to append the ContextMenu to this menu or turn that menu off and use the ContextMenu?
View 4 RepliesI 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'.
I have been reading and testing for hours. I am trying to edit an mdb (access) database from a DataGridView, connecting both with an ADODB connection. The DataGridView populates from the mdb, but whenever I try to edit it, the new information does not get saved to the mdb. Here is the code I am using.[code]...
View 2 RepliesI programmatically create a datagridview in my program. When the user first enters the datagridview with the mouse, the cursor changes to edit mode (thin vertical line) regardless of which cell is entered. I just want the cell highlighted (in selection mode I assume) as issubsequently done when the cursor is moved to a new cell.

is there a method of setting up my datagridview to show me textboxcolumns until editmode is entered? At which time I will swap some textboxcolumns for bound comboboxcolumns. And at the end of validation/exit edit mode I can swap back?
View 2 RepliesI have a datagridview. i fetched the data in the datagridview from the database(access) and then i want to edit the contents of the datagridview. the datagridview looks like this:
View 1 RepliesI 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.
