我在gridview中使用checkbox控件我想在checkboxchanged事件之前显示确认。
确认框正在询问问题但不回发它,什么都不做......
// CS
TemplateField field = new TemplateField(){
HeaderText = "AKTIF",
ItemTemplate = new AddTemplateToGridView("AKTIF")
};
field.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;
field.ItemStyle.HorizontalAlign = HorizontalAlign.Center;
field.ItemStyle.Width = Unit.Pixel(40);
newXGrid.Columns.Add(field);
// ITEMPLATE
public class AddTemplateToGridView : ITemplate
{
String columnName;
public AddTemplateToGridView(String colname)
{
columnName = colname;
}
void ITemplate.InstantiateIn(System.Web.UI.Control container)
{
if (columnName == "AKTIF")
{
CheckBox chk = new CheckBox() { ID="chkAktif", AutoPostBack=true };
chk.Attributes.Add("onclick","return confirm('Are you sure ?')");
chk.CheckedChanged += new EventHandler(l_CheckedChanged);
container.Controls.Add(chk);
}
}
void l_CheckedChanged(object sender, EventArgs e)
{
...
}
}
//我的复选框页面
<input id="ctl00_MainContent_ctl11_ctl02_chkAktif" type="checkbox" name="ctl00$MainContent$ctl11$ctl02$chkAktif" onclick="return confirm('Are you sure ?');setTimeout('__doPostBack(\'ctl00$MainContent$ctl11$ctl02$chkAktif\',\'\')', 0)">

改变这个:
chk.Attributes.Add("onclick","return confirm('Are you sure ?')");
到此:
chk.Attributes.Add("onclick","if (!confirm('Are you sure ?')) return false;");
为复选框设置AutoPostBack="true"
以在点击时触发回发。

您使用return with confirm对话框阻止javascript执行setTimeout()
。
试试这个:
if(confirm('Are you sure?'))
setTimeout('__doPostBack(\'ctl00$MainContent$ctl11$ctl02$chkAktif\',\'\')', 0);
else
return false;
