在写研究生系统审核功能的时候,有一个页面的gridview动态生成四列radiobutton,在gridview控件外有四个radiobutton分别控制这四列的全选中。那么当外面的某个全选按钮选中后,改变gridview里面的radiobutton选择,对应的全选按钮选中情况应该发生变化。为了实现该功能,需要在写好了radiobutton的OnCheckedChanged监听函数并添加到aspx页面后,再在gridview的RowDataBound事件中加入声明。
aspx页面部分代码:
<asp:TemplateField HeaderText="学位类别" 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="同意推迟" 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="弃权" SortExpression="xwkyqcj">
<ItemTemplate>
<asp:RadioButton ID="Qq" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="chenk_Qq" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
加入声明代码如下://给每个RadioButton1绑定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)
{ }
OnCheckedChanged函数:

{
//记录同意授予项个数
int t = gvData.Rows.Count;

RadioButton TySy = (RadioButton)gvData.Rows[i].Cells[5].FindControl("TySy");
if (TySy.Checked == true)
{//存在同意授予项
QbBty.Checked = false;
QbTc.Checked = false;
QbQq.Checked = false;
}
else
{
t--;
}
//Response.Write("<script>window.alert('进入同意授予发生变化方法。')</script>");
}
if (t == gvData.Rows.Count)

QbTy.Checked = true;
}
else

QbTy.Checked = false;
}
}
//同意延迟授予发生变化

{
