在寫研究生系統審核功能的時候，有一個頁面的gridview動態生成四列radiobutton，在gridview控件外有四個 radiobutton分別控制這四列的全選中。那么當外面的某個全選按鈕選中后，改變gridview里面的radiobutton選擇，對應的全選按 鈕選中情況應該發生變化。為了實現該功能，需要在寫好了radiobutton的OnCheckedChanged監聽函數并添加到aspx頁面后，再在 gridview的RowDataBound事件中加入聲明。

aspx頁面部分代碼：

?

<asp:TemplateField HeaderText="學位類別" SortExpression="gdxw"><ItemTemplate><%# Eval("gdxw")%></ItemTemplate><ItemStyle HorizontalAlign="Center" /></asp:TemplateField><asp:TemplateField HeaderText="同意" SortExpression="xwkyqxf"><ItemTemplate><asp:RadioButton ID="TySy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="check_TySy" /></ItemTemplate><ItemStyle HorizontalAlign="Center" /></asp:TemplateField><asp:TemplateField HeaderText="不同意" SortExpression="zdkxxf"><ItemTemplate><asp:RadioButton ID="BtySy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="check_BtySy"/></ItemTemplate><ItemStyle HorizontalAlign="Center" /></asp:TemplateField><asp:TemplateField HeaderText="同意推遲" SortExpression="kkzyxkxf"><ItemTemplate><asp:RadioButton ID="TyTcsy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="chenk_TyTcsy" /></ItemTemplate><ItemStyle HorizontalAlign="Center" /></asp:TemplateField><asp:TemplateField HeaderText="棄權" SortExpression="xwkyqcj"><ItemTemplate><asp:RadioButton ID="Qq" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="chenk_Qq" /></ItemTemplate><ItemStyle HorizontalAlign="Center" /></asp:TemplateField>

加入聲明代碼如下：//給每個RadioButton1綁定setRadio事件
????????try
??????? {
??????????? ((RadioButton)e.Row.FindControl("TySy")).Attributes.Add("OnCheckedChanged",?"chenk_TySy");
??????????? ((RadioButton)e.Row.FindControl("BtySy")).Attributes.Add("OnCheckedChanged",?"chenk_BtySy");
??????????? ((RadioButton)e.Row.FindControl("TyTcsy")).Attributes.Add("OnCheckedChanged",?"chenk_TyTcsy");
??????????? ((RadioButton)e.Row.FindControl("Qq")).Attributes.Add("OnCheckedChanged",?"chenk_Qq");
??????? }
????????catch?(Exception)
??????? { }
