asp.net|datagrid| a RadioButton server control is added directly to a template when you add a radio box using the DataGrid control, because. NET, it is not possible to have these RadioButton in the same group as the client. Then we can use the radio tag to implement it.
The following is the HMTL page code
<form id= "Form1" method= "POST" runat= "Server"
<asp:datagrid id= "DATAGRID1" runat= "Server" autogeneratecolumns= "False"
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<input type= "Radio" name= "RDO" <%# getchecked (DataBinder.Eval (Container, "DataItem"))%> value= ' <%# DataBinder.Eval ( Container, "DataItem")%> ' >
<asp:label runat= "Server" text= ' <%# DataBinder.Eval (Container, "DataItem")%> ' id= ' Label1 '
</asp:Label>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid> <br>
<asp:button id= "Btnok" runat= "Server" text= "OK" > </asp:Button>
The following is the data binding code in Page_Load
Dim arr as New ArrayList
Arr. ADD ("News Synthesis")
Arr. ADD ("Comprehensive Arts")
Arr. ADD ("movie")
Arr. ADD ("Education")
Arr. ADD ("drama")
Arr. ADD ("Military")
Arr. ADD ("Sports")
DataGrid1.DataSource = arr
Datagrid1.databind ()
Here is the code to get the selection in Btnok_click
Response.Write (Request.Form ("RDO"))
The following is the function that sets which radio in the binding item
Public Function getchecked (ByVal str As String) as String
If str = request.form ("RDO") Then
Return "Checked"
Else
Return ""
End If
End Function
