This question was there about 8 years ago, now I'm having the same problem with Urmel and still there couldn't be whenever I load data into my DataGrid (RowHeadersVisble=True), the RowHeaderCells are empty but the selected one that has an arrow. Is there a way to show the RowNumber instead of nothing or the arrow?

How to show tooltip on rowheader mouse over ... in datagridview ?
View 1 Repliesnumbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..
My code:
'when adding a new row

View 1 RepliesI have several DataGridView's that are located in several different containers. I want to display a small form in a precise location relative to the RowHeader when the user's mouse moves over the row header of the datagridview. How can I get the screen coordinates of the RowHeader? The code below does not display the form in the proper location.

View 2 RepliesI have a form with 1 DataGridView and 3 TextBox control which is txtName, txtAddress and txtDesignation. I have also MS Access Database Table with StaffName, Address and Designation. What I want is when I Double click firstrow DataGridView RowHeader.. the data from database will display in the txtName, txtAddress and txtDesignation respectively.. means StaffName for txtName, Address for txtAddress.

I want to know if VB.Net already has a control like this before I start wasting time building my own. I have a DataGridView that shows the row error symbol in the RowHeader if the update to the database is unsuccessful for that row. Currently, if you hover the mouse over the error icon it will show a default tool tip to display the error text.I would like the user to left-click the RowHeader and a small popup window will show the error text. Then when the user clicks somewhere other than the popup window it will disappear just like a context menu. do I need to build a form with no borders that has a large textbox in it, then setup an event so when the form loses focus it closes? Or does a context menu strip have the ability to support a large textbox? Or do I use a splash screen?
View 4 RepliesSomewhile back I got into the habit of manually line numbering my routines (in access) - yes just like it was in the 80's ... :)Only because it's seriously helpful in error trapping where reference to specific line numbers pops up in my trapping routine.

When I add a new row to an access database, I would like the primary key to be automatically incremented and entered. I've got this to work using a sql database, but it doesn't work with access for some reason. The following code works if I give the code a value for "@key" which is my primary key column. If I leave it out I get the error "Number of query values and destination fields are not the same". I don't want to have to supply the primary key, I want it to generate automatically.
[Code]...
In the database the primary key is type "AutoNumber". Does anyone know what I'm doing wrong?
Following on from my last question, are the AssemblyMajorVersion, AssemblyMinorVersion,AssemblyRevisionNumber and GenerateRevisionNumber properties required in .vbproj files?
All of our components have these entries in the .vbproj files but they are completely out of sync with the AssemblyVersion and AssemblyFileVersion entries in the AssemblyInfo.vb files.
Are they a legacy from the upgrade from previous VS versions?
