group:Datagrid multiple select
dotnet windows forms:
Hi all,
I have put some code in the mouseup event for my datagrid in order to select the entire row. Does anybody know how I can get multiple selection to work on my datagrid? thanks Gav
hi Gav,
i use the built-in multiple select by just holding down Ctrl while i click on the left margin of each row. is this what you want? tim -------------------------- blog: http://tim.mackey.ie
This is the behaviour that I'm after yes however i do not show the row
headers...

hi Gav,
may i ask what is your reason for hiding the row headers? you are re-creating functionality that is already there, and requiring the users to learn a non-standard way of selecting a row. most users will be familiar with the row-header way with excel. you must have a special case for doing this? i don't want to be a smart ass but before i/we try and help answer the question, it would be good to know the reasoning behind your course of action. did you try setting the width of the rowheader to 15 pixels? this makes it much less obtrusive in terms of screen space. tim -------------------------- blog: http://tim.mackey.ie [quoted text, click to view] "Gav" <spam@spam.com> wrote in message news:ey3xAptsFHA.1256@TK2MSFTNGP09.phx.gbl... > This is the behaviour that I'm after yes however i do not show the row > headers... > > "Tim_Mac" <Tim at mackey dot eye eee> wrote in message > news:uRJjjCwrFHA.1172@TK2MSFTNGP11.phx.gbl... >> hi Gav, >> i use the built-in multiple select by just holding down Ctrl while i >> click on the left margin of each row. >> is this what you want? >> >> tim >> >> -------------------------- >> blog: http://tim.mackey.ie >> > >
Why would this be a 'non-standard way of selecting a row' this is how all
listview controls work, look at the inbox of outlook/outlook express you have a list (with no column headers) which you can hold CTRL and click on multiple rows to select them. I guess I could have looked into making a editable ListView but that seems like a lot more work because the datagrid looks just the same when you hide the row headers, caption, set the back colour to white etc, then you already have a listview look that you can edit.

hi Gav,
sorry i didn't know you were using the datagrid to look and behave like a listview. in the normal datagrid situation, it would be non-standard. to be honest, i think the listview is the one you want. the WM10 library list is a listview. you can set LabelEdit = true, View=Details. you've got your multi-select built in, column sorting, etc. i couldn't get the items to BeginEdit() reliably on SelectedIndexChanged for some reason, it would flicker editable and then return to normal. will your users want to edit the text just by selecting an item in the list, or will the normal listview renaming functionality be sufficient? tim -------------------------- blog: http://tim.mackey.ie [quoted text, click to view] "Gav" <spam@spam.com> wrote in message news:e9i6qFJtFHA.616@TK2MSFTNGP11.phx.gbl... > Why would this be a 'non-standard way of selecting a row' this is how all > listview controls work, look at the inbox of outlook/outlook express you > have a list (with no column headers) which you can hold CTRL and click on > multiple rows to select them. > > I guess I could have looked into making a editable ListView but that seems > like a lot more work because the datagrid looks just the same when you > hide the row headers, caption, set the back colour to white etc, then you > already have a listview look that you can edit. > > Gavin > > > "Tim_Mac" <Tim at mackey dot eye eee> wrote in message > news:OXIMFtwsFHA.3596@TK2MSFTNGP15.phx.gbl... >> hi Gav, >> may i ask what is your reason for hiding the row headers? >> you are re-creating functionality that is already there, and requiring >> the users to learn a non-standard way of selecting a row. most users >> will be familiar with the row-header way with excel. you must have a >> special case for doing this? >> i don't want to be a smart ass but before i/we try and help answer the >> question, it would be good to know the reasoning behind your course of >> action. >> did you try setting the width of the rowheader to 15 pixels? this makes >> it much less obtrusive in terms of screen space. >> >> tim >> >> -------------------------- >> blog: http://tim.mackey.ie >> >> "Gav" <spam@spam.com> wrote in message >> news:ey3xAptsFHA.1256@TK2MSFTNGP09.phx.gbl... >>> This is the behaviour that I'm after yes however i do not show the row >>> headers... >>> >>> "Tim_Mac" <Tim at mackey dot eye eee> wrote in message >>> news:uRJjjCwrFHA.1172@TK2MSFTNGP11.phx.gbl... >>>> hi Gav, >>>> i use the built-in multiple select by just holding down Ctrl while i >>>> click on the left margin of each row. >>>> is this what you want? >>>> >>>> tim >>>> >>>> -------------------------- >>>> blog: http://tim.mackey.ie >>>> >>> >>> >> >> > >
Sorry to be a pain, I know your trying to help, but I do not like the idea
of doing it this way, you cannot bind a datasource to a listview like you can a datagrid, that was another reason for me to use datagrids over listview they are easier to use at design time. I still would have much prefered an answer to my original question, is it not possible to caption in the onclick that the ctrl key is being held and multiple select in that way?

hi Gav,
you're right. i should have just trusted that you knew what you wanted! i got this code to behave as you have described private void dataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) { if((Control.ModifierKeys & Keys.Control) == Keys.Control) this.dataGrid1.Select(this.dataGrid1.CurrentRowIndex); } interestingly this code in MouseDown wouldn't select the row. also datagrid_Click didn't fire for clicks inside the cells. hope this works for you. tim
Thanks for the reply I thought I had been forgotten about for a moment
there... I have tried this out and all it seems to do is select the whole row that I click on when I hold down CTRL, it doesn't seem to still keep the selection on the other rows.

hi Gav,
sorry i thought your original request was just to select the whole row. i lost track of it with all the posts. i'm all out of inspiration, except to suggest this control i just found: http://www.csharphelp.com/archives2/archive341.html. it is an editable listview control, with Ctrl+click multi select. if that doesn't work you could try a repost, stating that you have removed the rowheaders of a datagrid, but want to multi-select using Ctrl + click. good luck tim -------------------------- blog: http://tim.mackey.ie
Hi Gav,
I'm actually encountering the same problem as yours, meaning i want to be able to let users select multiple rows on a datagrid without showing the rowheaders with the row selector represented by an arrow. Could you find any solution to your problem ? Regards, Mike [quoted text, click to view] Tim_Mac wrote:

Sorry Mike, I do not have a solution as of yet, but I will surely let you
know when I do.

hi gav, did that control not serve your purposes?
http://www.csharphelp.com/archives2/archive341.html i downloaded and tried it out and it seemed to do what you wanted. tim -------------------------- blog: http://tim.mackey.ie
