Using a CheckBox to Select Rows in an ASP.NET GridView

Question

With a GridView control in .NET is there any way to change the Select option in a GridView to a Checkbox , how do you select multiple rows?

I tried adding a CheckBoxField into my GridView but when I ran it it didn't show up.

Answer 1

Adding checkbox to Gridview is as simple as adding TemplateField of any control.

There should be other columns binding data to the grid. Also, check visible property of checkbox.

Answer 3

I always just add a column to the DataTable that I am binding to.

dt.Columns.Add(new DataColumn("Include", typeof(Boolean)));

Or in my SQL I will have:

declare @include bit
set @include = 0
select 
@include Include,
....

Answer 4

I did work it out in the end, thanks to ExpertSoul for the headsup on the tutorial. This was all I needed in the markup and it worked great:

<asp:TemplateField>
    <ItemTemplate>
        <asp:CheckBox ID="PublicationSelector" runat="server" />
    </ItemTemplate>
</asp:TemplateField>

The other thing that the tutorial had which was great was an onclick event so that you could pick up the id # when the submit button was clicked, which was the next bit...

Great stuff.
