GridView Multi Select ?

[brianpmccullough]

hello,

I have just started playing with the GridView (Web Forms) control in ASP.NET
2.0. I have an application that I would like to use the GridView to select
multiple rows by simply clicking on the row, much like you can with a ListBox.

First of all, is MultiSelect possible in the GridView control?

Is there a way to get it to allow selection of a whole row by simply
clicking on the row (similar to a listbox control)?

Thanks!

-Brian

Hi Brian,

1- The GridView documentation only mention selectedRow attribute which
returns a reference to a single row:

2- Regarding your second question, search for a topic named "GridView whole
row select" that we discussed on this forum on Nov 29, where a Select
CommandField was created with a style that has display=none and a Javascript
added during the RowDataBound event simulate a click of the select button.

Another alternative, but a bit more involved, is to take control of saving
indicators to the selected rows in <input type="hidden"> object on the
webpage that you retrieve in the codebehind.

One more idea to implement a MultiSelect GridView is to add a
<asp:CheckBoxField > column as I did in this sample with the DataGrid:

I just placed a demo for a GridView where you can select multiple rows:
