on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

View 2 RepliesI am using VS2008 using VB. I have a datagridview sourced to a dataset. There are 5 fields mapped to the datagridview, three are read only. I am using the 'RowLeave' event to do some processing.
I am using the 'CellEnter' event to 'SendKeys" a tab in the read only cells. The question is simple: how do I allow the user to enter data into one of the 'editable' cells and change the 'Enter' key into a 'Tab' key, so that the data they entered is in the cell and I tab over to the next 'editable' cell, even if it is in the next row?
I'm trying to figure out how to get a query for multiple columns in my dataviewgrid.. So far i havn't even been able to make a single column query work, when i search something in First_Name for example, it returns nothing. ive used query builer, ive written the code myself, nothing seems to work.
View 3 RepliesI added a DVG to the form. Then I clicked on the small box and selected a data source through the design screen. I chose the connection and then the sproc to get the data. This all works fine. That was added in the Load sub automatically. I will make changes to the cells by code rather than allowing the user to change the cells themselves. Then I want to click a button and save the changes to the table. Everything I have tried does not work.

I am trying to search a Access Db via a TextBox1 a Button1 and a dataviewgrid.My sql statement loks like this:
Select LastName FROM Clients WHERE (LastName LIKE 'TextBox1.text')
This doesn't work I have tried '" & "' around the textbox words I've tried '& TexBox1 &'. This I tried to learn from Data over forms video-- LIKE @LastName +'%' that really didn't work. If I use = "Bla bla" it will work but the LIKE word does not. Even a point in the right direction. I've spent many many many hours on this. And what makes me mad is I've done it somhow before even with a combobox as a variable in the SELECT "var" but anywayI'm wondering now if the LIKE statement isn't used in Access? and if the % wildcard is used in Access?
I wanted my search result to display in the DataViewGrid but it shows nothing when i click the search button or anything i did wrong?

For some time ago i have notice that my App on every start make a call to csc.exe and starts it. I know for sure that that did not happened before and I can not find out why this is happening now, or better to say: what did I do in code to make this happened? I have google-it and found out that csc.exe is some kind off on-the-fly compiler for C# (If I understand it correctly ) but my App is in VB.net so I am a bit confused. Can someone explain it to me in general what have I did in my VB.NET code to make my App on every start calls csc.exe?

the issue is that customactions class in my VB 2010 code, correctly configured, does not start the program after installation, neither sets the autorun, it seems that subroutine OnAfterInstall isn't invoked at all.
Note that process termination before installation (for upgrading purpose) eventually works.
