I would like to disable users from blanking the nud.Leave a comment:

I want to handle blank entry to numericupdown. It seems that if the numericupdown .value is zero, then I select the number then delete it, the nud retains the value zero. the problem is the display is blank.
You can simulate this by creating a form and place a nud control. Run the app then delete the value from the nud. It is blank, but it really is the last number it is. I tried to refresh the nud but nothing happens.Leave a comment:

VB-APP: Problem on numericupdown control
Nud has no textchanged event. Although nud only accepts numbers, it accepts blank as well. This is the problem I'm having. If it only has a textchanged event, I would have done something like this
ontextchanged.. .
if nud.text = "" then
nud.value = 0
end if
Is there a solution to this? -

VB-APP: How to determine rows of a child based on parent row selected.
Good day Sirs & Madams, I know some of you will find this problem very simple. Kindly share a little knowledge to me on how to deal with this. Thank you.
I have a parent-child table relation. when bsParent is navigated, bsChild follows. In code, I did this to determine the rowstate:
...Code:dim dtParent as datatable = ds.Parent.copy for i as integer to dtParent.defaultview.count - 1 if dtParent.defaultview(i).row.rowstate

VB-APP: What event happens when the bindingsource is filtered?
Hello all. I would like to place code when bindingsource is being filtered. I have tried placing it in the positionchanged and listchanged event. But, when I try to filter the bindingsource, it doesn't call the positionchanged or listchanged event.
I tried placing a msgbox("Fire") statement in that two events just to check if it fires when I filter the bindingsource. When I filter the bindingsource, the messagebox doesn't... -
Any help here? Or any links that anyone can share?
UPDATE 3:
I noticed that the code works (I think). I noticed that the first time I clicked the button it assigns dtt to the datasource pretty fast. The next clicks I do to filter tend to slow down the assigning of dtt as the datasource. Hence, the program not responding. Does anyone know a correct workaround for this? Or any links that explains this behavior? Thank you very...Leave a comment:

Good day to all! I was trying to search the internet about this problem but I still can't seem to stumble upon an answer.
I am using a BindingSource on my program and everything is ok except that the users can edit any record they want before saving them all in one click. Well, this is fine when doing common saves. But, in my program, I have placed validations for each particular fields.
When I add or edit a record then... -
vb.net + mysql: how to modify connection created by dataset designer
