在寫研究生系統審覈功能的時候,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。那麼當外面的某個全選按鈕選中後,改變gridview裏面的radiobutton選擇,對應的全選按鈕選中狀況應該發生變化。爲了實現該功能,須要在寫好了radiobutton的OnCheckedChanged監聽函數並添加到aspx頁面後,再在gridview的RowDataBound事件中加入聲明。 html
aspx頁面部分代碼: 函數
<asp:TemplateField HeaderText="學位類別" SortExpression="gdxw"> <ItemTemplate> <%# Eval("gdxw")%></ItemTemplate> <ItemStyle HorizontalAlign="Center" /> </asp:TemplateField> <asp:TemplateField HeaderText="贊成" 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="不一樣意" 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="贊成推遲" 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>
加入聲明代碼以下://給每一個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");

catch (Exception)
