我正在尝试从列表框中删除和计时,但我收到此错误

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>
我试过
I have tried
enableEventValidation="false"
但页面无效它的方式。
ListBox将从Gridview中填充。但我认为每次点击页面上的按钮时,列表都会更新
。
感谢你的回复。
我尝试过的事情:
but the page is not working the way it should.
The ListBox is getting populated from a Gridview. But I think the list gets
updated everytime I click a button on the page.
thanks for you response.
What I have tried:
int a = LBDuties.SelectedIndex;
LBDuties.Items.RemoveAt(a);
// LBDuties.Items.Remove(LBDuties.SelectedValue);
// LBDuties.SelectedIndex = 1;
推荐答案
List<string> temp = new List<string>();
foreach (string item in listBox1.Items)
{
string removelistitem = "RemoveValue";
if(item.Contains(removelistitem))
{
ArraySample.Items.Add(item);
}
}
foreach(string item in ArraySample)
{
listBox1.Items.Remove(item);
}
