View 1 RepliesSaving Changed Data Before DataViewGrid Selection (Row) Changed?
Jan 20, 2010on 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?

Forms :: Clear The Dgv When The User Blanks The Combobox Without Necessarily Changing The Selection Index?
Oct 25, 2010I have just realised that ComboBoxes don't have a Change event. I have a combobox filled with a few items, eg. Bakery, Deli, Fruit & Veg, etc. Choose one of these items, all the related items show in the dgv. However, when I blank the text in the Combobox (press Delete key whilst Combobox has the focus), what event fires so I can blank the dgv? The combobox does not contain a Blank item. Even if it does, the Blank item only fires the ComboBox1_SelectedIndexChanged when the user scrolls down to, or clicks on, the blank value.
I want to clear the dgv when the user blanks the combobox without necessarily changing the selection index.

View 2 RepliesDB/Reporting :: DataViewGrid Enter Key For Windows
Aug 16, 2009I 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?

Then I want to click a button and save the changes to the table. Everything I have tried does not work.

Search A Access Db Via A TextBox1 A Button1 And A Dataviewgrid?
Feb 15, 2012I 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?

Why Did Clear() Clear Both DataTables
Feb 28, 2011In my winform program (in vb.net) I wrote:

'Get data from DB into dt

[Code].....
But when I run the program, Clear() cleared both dt and dttemp! Why? Aren't dt and dttemp supposed to be two distinct instances of DataTable?
(I finally found a solution - dttemp = dt.Copy() instead of dttemp = dt. But I still can't see why Copy() was necessary in this case.
