Multiple selection in Datagrid w/o RowHeaders
Hi All,
I'm developing an app where I have a situation wherein I need to allow users to select multiple rows of a DataGrid without using RowHeaders. I need to give users all the facilities of selecting multiple rows of the grid using CTRL button and clicking the rows in the grid but I can't use the RowHeaders (this is the client's requirement). Can somebody help me in this... I know there is a Select method of a grid which allows to select a whole row but how will I be able to know which row of the grid user has selected???
Thanks.
Debsoft

Hi there,
By default, a DataGrid does not support selecting multiple rows at once. One way to overcome this, is to add a column with checkboxes your user can check. At the server you can loop through the items in the grid and see what checkbox was checked. Take a look here for an implementation of this:

Your Ctrl-Click requirement can also be solved with this. Add some JavaScript that detects the rows that are clicked, and save the values of the clicked rows in hidden fields or JavaScript variables that are submitted back to the server. This way, you don't need the column with Checkboxes.
Cheers,
Imar

Hi Imar,
Thanks for your reply... I have found a solution to my problem. Basically I simulated the actions that occur when using RowHeaders.
I trapped an event of DataGrid(CurrentCellChanged) and in this event I checked which row was clicked by the user...then I stored the clicked row in a list(collection of rows clicked) and also selected that row by using the Select method of DataGrid...So I did without using RowHeaders...It's working fine now...Thanks
Regards,
Debsoft
