I'm using a DGV to show some data & I'm using the CellClick event to run some code when the user clicks on each row. But I also want to run some other code if the user double clicks a row, but the CellDoubleClick event never fires, the CellClick event just fires twice. Does anyone have any ideas on how to make both events work?

I need to find out the order of events that are fired when a Row is updated in a DataGridView control. I have looked just about everywhere and cannot find this simple information.
View 6 RepliesI'm writing a Windows Forms app that uses a DataGridView control. I have row select enabled on the control. I would like to trap the DoubleClick event, but it doesn't seem to fire reliably - I often have to double-click on a row 2 or 3 times before the event is triggered. Could anyone point me to a way to capture this more reliably?
View 1 RepliesI have a mixed DGV of bound fields and an unbound checkbox. The DGV uses an SQL statement with a Group By clause. I then populate the DGV via table adapter/DS. So, I have two issues, first I need to get the status from another table that has the value of 0 or 1 in a column and set that checkbox. The part number already loaded into a cell will link to this table. I cannot link this table directly to my Group By table because it would lose its logic. The second issue, is changing the checkbox and saving it both to this table and the DGV for display.
I'm confused at which events in the DGV will need to be fired to do these tasks?This code seems to work OK but seems to run a little slow. So, i'm wondering if my approach to this is incorrect.

What is the Coding for the double click event of data gridview and when it click will shown the data in to the textbox. for example in listview
with listview1.selecteditems(0)
textbox1.text=.subitems(1).text.
I have a datagridview populated from a dataset datatable and all works well. Changing the values of columns updates the datatable except - if the 1st value changed is the last column on a row, the cellparsing and cellvaluechanged events don't fire. Others may not fire but these two I've been working with. The CellLeaving event fires and the RowLeaving event fires. Going back to the cell and changing the value again does cause the events to fire and everything works fine than.
why the events are not firing the 1st time a value is changed?
In debug I see that the datagridview iscurrentcelldirty value is true and also edit mode.
I have a windows form that can search for data and the results are results are returned in a Datagridview. The Datagridview is bound to a custom datatable object. On the CellDoubleClick and CellContentDoubleClick events, a new form is supposed to open which will display the results of that row. What I am noticing is that the datagridview doesn't always fire when I immediately double-click on a particular row. It would appear that I have to first click on the row to "select" it, then double-click the row so the event will fire. Is there a way to remove this intermediate "select" step? Is there a property in the Datagridview that needs to be activated so the double-click events will fire right away? Does something possibly need to be done in another DatagridView event?

I don't really know how to call this...Anyhow... I have two objects (for example, "A" and "B") of the same type/class. I have an event (for example, "Refreshed") in both objects. Is it possible, that when "Refreshed" fires in "A", it also fires in "B"?
Edit: forgot to mention - "A" and "B" don't "know" each other.
I have a base object, with a event that can be triggered by multiple methods.Then I created a child object that inherits that base object. I want to be able to trigger that event in the new object; but I can't use RaiseEvent to raise a base-object's event.To get around this, I created a small method in the base object that takes the argument for the event and I just use it to trigger the event. Is this the proper way to handle this situation? Similarly, I could Shadow the event with a duplicate one in the child object.Is there a standard way to handle events across inheritance?

I've got a series of textboxes that are bound to a dataset. I've got them disabled and will be hiding them. Then I have a series of check boxes related to each textbox. The user clicks the check box and I change the value of the databound textbox. Nice and easy way to bind check boxes to DB fields. Any way to create these relationships at runtime - basically creating the events that I'm hardcoding right here.

View 2 RepliesI've been working on an application recently and it has exceeded the scope of a single form.I decided that it would be a good time to use an MDI container and split the interface up over a number of different child forms.As the application was written, there were a few different classes that were being instanciated on the original form.I've migrated these over to the MDI parent form so that I can allow all of the children to interact with them.The route that I'm going down right now is raising events on the child forms and watching for them on the MDI parent.The parent form is then doing whatever the child did to the instanciated classes in the past.

View 5 Repliesi have created a list of buttons using the following
Dim Butt(20) As Button
Dim i As Integer = 0
While (i <= 20)
Butt(i) = New Button
Me.Controls.Add(Butt(i))
i = i + 1
End While
this means that buttons are created in the code and not on the form to begin with, so I don't know how to create an event for the click of a button in a list. Is it possible to do it with a parameter for i so that there is only 1event for all buttons in the list, and i is the button index array clicked?
