Hi all,
I've been trying to have a simple checkbox in my datagrid
using C# and it's being a pain to get it to work.
Here is the cenario.
I have a DataSet populated with a table "Employees" let's
say. This table has fields such id, name, email.
All I want to do is to display an extra column in my
datagrid that will display a checkbox for each row.
Note, there is no data associated with this checkbox. I
just wanted the user to select some of the Employees from
the datagrid by checking the checkbox. Then, when they
click the button "Print", I will loop through the
datagrid, get the selected ones and print.
Anyone can give me some instructions or example of how to
do that?
I've been looking some people examples that do something
similar. But they don't really show how to add an extra
column to the datagrid with a checkbox for each record of
your already populated dataset.
Please, any help will be appreciated.
Thanks to all.
Anderson

In your Web Form (aspx page) add something like the following to your
datagrid
<asp:datagrid id="dgEmployees" runat="server"...
....
<asp:TemplateColumn HeaderText="Select">
<ItemTemplate>
<asp:CheckBox id="chkEmployees" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
....
</asp:datagrid>
in your code behind on the "print" handler add the following:
DataGridItem dgItem = null;
int iEmployeeId = 0;
CheckBox chkBox = null;
for (int i=0; i < dgEmployees.Items.Count; i++)
{
dgItem = dgEmployees.Items[i];
chkBox = (CheckBox)dgItem.FindControl("chkEmployees");
if ((chkBox != null) && chkBox.Checked)
{
// Assuming you ID column is the first cell
iEmployeeId = int.Parse(dgItem.Cells[0].Text);
//Now run your print code here for this employee id
//Response.Write(String.Format("{0}<br>",iEmployeeId.ToString()));
}
}
