[DataGrid tip] adding radiobutton to the DataGrid template column is a single choice.

Sourcecode: testsingleselect.rar

Write down JavaScript first:<Script Language="Javascript">

VaR Flag = 0 ;
VaR Lastobj;

  Function Cancelselect (OBJ ){

If (Flag =   0 )
{
Lastobj = OBJ;
Flag + = 1 ;
}
Else
{
If (Lastobj. ID ! = OBJ. ID ){
Lastobj. Checked =   False ;
Lastobj = OBJ;
}

}
}
</ Script >

Add radiobutton to the template column and activate javascript:

< Itemtemplate >
< ASP: radiobutton ID = "Rbselect"   Onclick = "Javascript: cancelselect (this );" Runat = "Server" > </ ASP: radiobutton >
</ Itemtemplate >

After Code To obtain the selected radiobutton Dim Demogriditem As Datagriditem
For   Each Demogriditem In Grdemployees. Items
Dim Myradiobutton As Radiobutton =   Ctype (Demogriditem. cells ( 0 ). Controls ( 1 ), Radiobutton)
If Myradiobutton. Checked =   True   Then
Myradiobutton. Checked =   False
' Get select radiobutton
End   If
Next
