datagridview cell validating event-7

I owe you one, Bob "Bart Mermuys" In a datagridview (vs2005, VB.net) I have two columns that are checkboxes. Value" for both Check Box, only for the non-editing Check Box, for the the editing Check Box you need to use e. (Note, Formatted Value is either a Boolean (Three State=false) or a Check State (Three State=true). Data Grid View Cell Validating Eve nt Args) Handles Datagrid1.

otherwise the event does a validation on other types of fields and returns errors, but that was easy. I think common behaviour is so that the user can't leave the cell once validation fails and is forced to correct it before he can leave the cell. But there is a problem in your code, you can't use "Data Grid View[,].

Cancel = True End If End If End Sub Say I checked just one checkbox Cell_1 to start, the code allows the change to be made. I press the sacep key after the e,cancel and the message and I get the same problem.

Data Property Name = "Cell_2") Then If CBool(Datagrid1("Cell_1", e. Private Sub Datagrid1_Cell Validating(By Val sender As Object, By Val e As System.

Cancel = True End If End Sub HTH, Greetings End If End Sub Say I checked just one checkbox Cell_1 to start, the code allows the change to be made. I press the sacep key after the e,cancel and the message and I get the same problem. Data Property Name = "Cell_2") Then If CBool(Datagrid1("Cell_1", e. Its not permissible to have the two selected to true, but they can both be false. Error Text = "" Dim other Check As Boolean = False If (Datagrid1.

I need to check that only one of the two can be checked. Data Property Name = "Cell_1") Then other Check = CBool(Datagrid1("Cell_2", e. Private Sub Datagrid1_Cell Validating(By Val sender As Object, By Val e As System. Oh by the way, I had to add an if condition to do the testing in the cellvalidating only when either of these two checkbox fields gets edited. Data Property Name = "Cell_2") Then other Check = CBool(Datagrid1("Cell_1", e. I wrote code in the cellvalidating event as follows. I noticed that when I click on the checkbox to uncheck it after the e.cancel executed, that click does not change its value, I can both see in the UI that the value did not change before the cellvalidating event is called and in the cellvalidating event itself, when I set a breakpoint after the line that checks and verify the value of CBool(Datagrid1("Cell_2", e. I'm going to revisit the sample mdb that I sent to the newsgroup, I still wonder why that did not work. NET doesn't use a short-circuiting AND operator by default and therefore CBool is used on other cells too. Its not permissible to have the two selected to true, but they can both be false. Error Text = "" Dim other Check As Boolean = False If (Datagrid1. I wrote code in the cellvalidating event as follows. Its not permissible to have the two selected to true, but they can both be false. Error Text = "" Dim other Check As Boolean = False If (Datagrid1. Private Sub Datagrid1_Cell Validating(By Val sender As Object, By Val e As System. I noticed that when I click on the checkbox to uncheck it after the e.cancel executed, that click does not change its value, I can both see in the UI that the value did not change before the cellvalidating event is called and in the cellvalidating event itself, when I set a breakpoint after the line that checks and verify the value of CBool(Datagrid1("Cell_2", e. What I realize now is the the e.cancel will prevent the cell from bieng changed or pushed to the unbderlying database but even when user changes cell back to what it should be or presses esc and cell comes bacj the error icon remains in the row selector. I,m going to make a really simple sample with a realy small Access database and post it here soon. I think common behaviour is so that the user can't leave the cell once validation fails and is forced to correct it before he can leave the cell.
