[英]Check multiple items in ASP.NET CheckboxList
I try to check multiple values in ASP.NET CheckboxList but I couldn't.我尝试检查 ASP.NET CheckboxList 中的多个值,但我做不到。
I Wrote:我写:
chkApplications.SelectedValue = 2;
chkApplications.SelectedValue = 6;
But it just selects item with value '6'但它只是选择值为“6”的项目
What's wrong?怎么了?
The best technique that will work for you is the following:最适合您的技术如下:
chkApplications.Items.FindByValue("2").Selected = true;
chkApplications.Items.FindByValue("6").Selected = true;
OR you can simply do it like...或者你可以简单地这样做......
foreach (ListItem item in chkApplications.Items)
{
if (item.Value == "2" || item.Value == "6")
{
item.Selected = true;
}
}
you can put the value in a list ( MyList
), and use FindByValue
to check them.您可以将值放在一个列表 (
MyList
) 中,并使用FindByValue
来检查它们。
foreach (var item in MyList)
{
checkBoxList.Items.FindByValue(item.id).Selected = true;
}
foreach (var item in cb.Items.Cast<ListItem>()
.Where (li => li.Value == "2" || li.Value == "6"))
item.Selected = true;
Instead of trying to select the item through chkApplications.SelectedValue
try chkApplications.Items.Item(2).Selected = True
chkApplications.Items.Item(6).Selected = True
而不是通过
chkApplications.SelectedValue
尝试 select 项目尝试chkApplications.Items.Item(2).Selected = True
chkApplications.Items.Item(6).Selected = True
