(Read from http://www.dotnetBips.com/displayArticle.aspx?id=147 Source Code Download) This problem occurs because the Radiobuttons control cannot be added directly in the DataGrid template column. Because DataGrid will generate a unique name to each radio button so that these radio buttons are not a group.
The solution to the problem is to add a Label control in the template column. Write elements in the DataGrid ItemDatabase, such as:
IF
E.Item.itemType
=
ListItemType.alternatingItem
Oral
E.Item.itemType
=
ListItemType.Item
THEN
DIM
r
AS
Label R
=
E.Item.FindControl
"
Label2
"
R.Text
=
"
"
&
E.Item.cells
1
) .Text
&
"
> "
End
IF
If you want to get the selected value, you have to use Request.Form to get it.
Label3.Text
=
REQUEST.FORM
"
MyRadiogroup
"
)
If you want to keep the status after postback, you have to do it yourself.
DIM
i
AS
DataGridItem
For
Each
i
In
DataGrid1.Items
IF
ItemType
=
ListItemType.alternatingItem
Oral
ItemType
=
ListItemType.Item
THEN
DIM
r
AS
Label R
=
I.FindControl
"
Label2
"
)
IF
R.Text.indexof (label3.text)
>
0
THEN
R.Text
=
"
"
&
I.cells
1
) .Text
&
"
Checked> "
Else
R.Text
=
"
"
&
I.cells
1
) .Text
&
"
> "
End
IF
End
IF
NEXT
