Anyone know how to prevent people from deleting rows from a grid, but still allow them to select the cells and whatnot? I don’t want to set the grid to enabled because then they can’t even click things.
Setting it to read only still allowed a delete to happen.
I tried setting the grid.Override.AllowDelete = False, but that did not work.
I don’t want a BPM to stop the delete, because it needs to happen for that dataview in other areas.
For context, I want to prevent users from deleting rows from the Order Entry Summary tab, but allow it everywhere else.
//Class Level
Ice.Lib.Framework.EpiUltraGrid myGrid;
//Get a Hold of the GridOn the InitCustomCodeFunction
myGrid = csm.GetNativeControlReference("<GuidHere>");
grid.BeforeRowsDeleted += new Infragistics.Win.UltraWinGrid.BeforeRowsDeletedEventHandler(myGrid_BeforeRowsDeleted);
//Be a good citizen and destroy the handler in your Closing Function
grid.BeforeRowsDeleted -= new Infragistics.Win.UltraWinGrid.BeforeRowsDeletedEventHandler(myGrid_BeforeRowsDeleted);
//Declare your handler function and "jhandle" the delete event (AKA Cancel)
private void myGrid_BeforeRowsDeleted(object sender, Infragistics.Win.UltraWinGrid.BeforeRowsDeletedEventArgs args)
{
args.Cancel = true; //this "cancels" the delete event
}
Try seeing if you can stop it in the RowDeleting instead because after it comes RowDeleted
this.QuoteQty_Column.RowDeleting += new DataRowChangeEventHandler(this.QuoteQty_RowDeleting);
private void QuoteQty_RowDeleting(object sender, DataRowChangeEventArgs args)
{
if (QuoteQty_Column.Rows[modRowIndex].RowState.ToString() != "Deleted")
{
// Just a snippet from something else; conceptual try looking up the RowDeleting Event
}
}
You have it on QuoteQty_Column–does it matter which column is used?
I assume if the row is being deleted, that you could perform that check on any of the columns in the grid, right?
FYI I like you couldnt use the BeforeRow stuff so I used these 2 BUT I needed to detect if its deleted, not sure If you can prevent it I assume you can if its in RowDeleting.
this.QuoteQty_Column.RowDeleting += new DataRowChangeEventHandler(this.QuoteQty_RowDeleting);
this.QuoteQty_Column.RowDeleted += new DataRowChangeEventHandler(this.QuoteQty_RowDeleted);
I’m not so sure I can make that work since the Order Entry Summary grid and the Order Entry Line List grid both use the OrderDtl binding. It would be the same DataView.
I don’t want to prevent users from deleting from the line list view.
SO I got it to work but its a shitty hack and I don’t like it. Here if (YOU) implement it, that’s up to you LoL
I put a BeforeAdapterMethod event on the salesOrderAdapter
case “Delete” then I check to see if the grid has focus… if it does I “handle” it. however that does break the ability for someone to hit the Delete button on the toolbar while focused on the grid.
good question lol thats what the Wizards use in Quote Entry.
