View 3 RepliesVB 2010 form has 1 panel, 1 DGV in the panel, 1 TabControl with 3 tabs in the panel each tab has a DGV all 4 bound to the same DataSet through code.
I have a form that has multiple Datagridviews on it, 1 in the main portion of a panel and the other 3 in a tabcontrol. If I click on cell 0,4 of DGV1 cell 0,4 of DGV2 is also "hilighted" and the same goes in the reverse order. If I click on cell 1,4 in DGV 1, cell 0,1 is hilighted in DGV2 (basically it stays with the last selected col and what ever row for that DGV).
This isn't the functionality I'm really looking for here, when I single click or change cells on any of the DGV's I don't want any of the others doing anything.
As you can see there are 2 cells selected this was created by a single click in the 4th cell of Param0

View 1 RepliesI have a DataGridView. I'd like the user to be able to select multiple cells using ctrl/shift. Then, as they type, I want the contents to update in all the selected cells. I'd prefer it if this happened as they type but I'd live with it updating the other selected cells when they leave the current cell.
I've tried hooking in to various events to to this but in each case there seems to be one problem or another that stops me doing it.
The following code records the row and column of a selected cell.
