【问题描述】:
我在用户控件页面加载中遇到以下异常。我试过在谷歌上搜索这个,但没有找到太多信息。请让我知道是否有人可以帮助我。
情况是,不同语言的各种用户控件都有一个 ascx.cs 文件。
应用程序运行正常,但有时会抛出此异常。

this.MId = int.Parse(Request.QueryString.Get("MId"));
*/
HideAllForms();
AddValidationAttributesToControls();
**BoundAccountsOfMember();**
BoundWithdrawMethods();
/*
* if (IsNetentConfirmationRequired())
LoadNetentConfirmationForm();
*
*/
CurrentPayoutMethod = (PayoutMethodEnum)Convert.ToInt16(SessionController.GetSessionData<object>("PayoutMethod"));
}
PlaceHolder phWithdraw = this.FindControl("phWithdraw") as PlaceHolder;
Panel pnlKYC = this.FindControl("pnlKYC") as Panel;
if (SessionController.CurrentMember != null && SessionController.CurrentMember.Approved == 10)
{
phWithdraw.Visible = false;
pnlKYC.Visible = true;
}
else
{
phWithdraw.Visible = true;
pnlKYC.Visible = false;
}
}
请在后面找到BoundAccountsofMember方法代码。
private void BoundAccountsOfMember()
{
Dictionary<Int16, AccountType> accountTypes = SessionController.CurrentMember.GetAccountTypes();
ddlWithdrawFrom.Items.Clear();
foreach (AccountType accountType in accountTypes.Values)
{
ddlWithdrawFrom.Items.Add(new ListItem(accountType.AccountName, accountType.AccountId.ToString()));
}
ListItem li = ddlWithdrawFrom.Items.FindByValue(SessionController.DefaultAccountId.ToString());
if (li != null)
{
ddlWithdrawFrom.SelectedIndex = -1;
li.Selected = true;
}
}
上述异常是从 Page_Load 事件中引发的。 问候 斯里维迪亚
