我在gridview中使用复选框控件,我想在checkboxchanged事件之前显示确认。
确认框询问问题,但不回发,什么也不做...
// 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)
{
...
}
}
//页面上的我的复选框
<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)">
最佳答案
更改此:
chk.Attributes.Add("onclick","return confirm('Are you sure ?')");
对此:
chk.Attributes.Add("onclick","if (!confirm('Are you sure ?')) return false;");
将Checkbox设置为
AutoPostBack="true"
以触发点击后的回发。关于c# - 如何在asp.net中更改复选框前使用确认?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/9704068/
