• Rajesh Kulkarni Checkbox in a datagridview

  Hi, I need to catch the checked event of a checkbox in a row that is in a datagridview. The dgv is binded to a bindingsource which bind a dataset and when a checkbox is clicked, a method is executed that uses the checked status of those checkboxes including the one clicked of course. CellClick doesn't seem to change the status in the dataset until the event is done and CellContentClick does nothing at all. There is ValueChanged but the focus needs to be changed for it to work.

• chadhowell C++ Drag and Drop

  I know there have been lots of questions asked about this, but I can't see any that answer my particular one. I have pictureboxes that I want to be able to move round a panel freely - they contain bmps. I have implemented the dragdrop events of the panel like so: private: System::Void pnlDragDrop_DragDrop(System::Object^ sender, System::Windows::Forms::DragEventArgs^ e) { PictureBox^ picPole = safe_cast <PictureBox^> (sender); picPole->SetBounds(posx, posy, picPole->Width, picPole->Height); } private: System::Void pnlDragDrop_DragEnter(System::Object^ sender, System::Windows::Forms::DragEventArgs^ e) { e->Effect = DragDropEffects::Move; } private: System::Void pnlDragDrop_DragOver(System::Object^ sender, System: ...Show All

• Evgeny Popov Datagridview / Backgroundworker and Web Service

  Hi There I have a datagridview1 filled with data. A user multi-selects certain records after which I take the selected records and add them to datagridview2. This is the final review process for the user. From here I need to insert these records into a new table. Everything is done using an XML webservice I'm writing. I know how to get data from the webservice into the datagridview1. I also know how to add the selected rows to datagridview2. I also know how to insert a new record from the datagrid1 using a webservice into the database using an INSERT stored procedure in SQL server 2000. But here's the catch, I use a backgroundworker to do the inserting/calling the webservice to insert the record. When I loop through datagridview2 row by ro ...Show All

Beth the data in the dataset is disconnected from the database. You will have to refill the dataset to see the changes made to the database. ...Show All

• PatriotB Can't get DrawItem event any more, in some special case

  This interesting thing was found by use of DebugView to monitor the all events. Suppose that there are 2 controls, one is propertyGrid, one is myListBox, which is a subclass of ListBox. myListBox uses OwnerDrawFixed mode, so it has to draw all items manually. However, in some mysterious case, I found that when I repeatedly opened and closed the propertyGrid, myListBox may never raise any DrawItem event. I output all events to DebugView, then found that WM_PAINT was there, but didn't WM_DRAWITEM. Also it can't restore from this bad status no matter what I did (move, refresh, resize, maximize, minimize...), until I recreate another myListBox. I think WM_DRAWITEM is nowhere to be manually emitted, since it's managed by control. ...Show All

• Ancalagon menuStrip1.Renderer.DrawSeparator problem(error)

  Hey, I am using menuStrip1.Renderer.DrawSeparator to use my own image for the seperator for the menu strip in my program. I tryed doing this: menuStrip1.Renderer.DrawSeparator = SurfScape1.Properties.

• stfkbf Datagridview combobox query

  I have a datagridview with 5 columns which a populate with dataset, which retrieves data from a table. The first column in the datagridview is a combo box which contains IDNumbers.
