数据存在于lstListSource中，但不具有约束力。
objLogEntries.Message.AppendLine("Bind ListBox with list started...");
listBoxControl.DataSource = lstListSource;
listBoxControl.DataTextField = strDataTextField;
listBoxControl.DataValueField = strDateValueField;
listBoxControl.DataBind();
objLogEntries.Message.AppendLine("Bind ListBox with list ended...");
Log.WriteTraceLog(objLogEntries);
它抛出异常：lstlnkSRAlias'(ID of listbox) has a SelectedValue which is invalid because it does not exist in the list of items
答案 0 :(得分：1)
您未正确使用DataTextField或DataValueField。它应该设置为您尝试绑定到的对象上的属性名称。类似的东西：
listBoxControl.DataSource = lstListSource;
listBoxControl.DataTextField = "Text";
listBoxControl.ValueMember = "Value";
listBoxControl.DataBind();
此外，如果正在刷新绑定，请在设置数据源之前清除列表：
listBoxControl.Items.Clear();
listBoxControl.SelectedIndex = -1;
listBoxControl.SelectedValue = null;
listBoxControl.ClearSelection();
listBoxControl.DataSource = lstListSource;
