Vb net cellvalidating cancel

posted by | Leave a comment

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[,].

I wrote code in the cellvalidating event as follows.

If I then ckeck the second checbox (cell_2), it gives me the error message but does not return the second checkbox I checked to its unchecked state. Any help appreciated, Bob Bart, I adapted your code to my datagridview, works like a charm. Data Property Name = "Cell_2") Then other Check = CBool(Datagrid1("Cell_1", e.

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. I wrote code in the cellvalidating event as follows. Data Grid View Cell Validating Eve nt Args) Handles Datagrid1.

Its not permissible to have the two selected to true, but they can both be false.

When I reopen it I can see that the chages were not comitted to the database, which is fine.

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.

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. I owe you one, Bob "Bart Mermuys" In a datagridview (vs2005, VB.net) I have two columns that are checkboxes.

I'm going to revisit the sample mdb that I sent to the newsgroup, I still wonder why that did not work. Greetings otherwise the event does a validation on other types of fields and returns errors, but that was easy. I need to check that only one of the two can be checked. Its just that my UI does not respond correctly and I can't expect my users to get out of it that way. Bob "Bob" In a datagridview (vs2005, VB.net) I have two columns that are checkboxes.
