RowFilter问题 [英] Problem with RowFilter

问题描述

当我尝试更改行值时，出现无法对System.String和System.Int32执行="="的操作.错误.
字符串接收者= Common.GetReceipientType(Convert.ToInt32(row [ReceipientType]));

row [ReceipientType" =收件人； -在这里抛出错误

只有在我执行以下语句时才会发生这种情况
dvGenericNotifications.RowFilter = String.Format("receipientType = {0}"，ddlType.SelectedValue);

when i try to change row value i am getting "Cannot perform ''='' operation on System.String and System.Int32. " Error.
string receipient = Common.GetReceipientType(Convert.ToInt32(row[ReceipientType]));

row[ReceipientType"] = receipient; -- here throwing error

This is only happens when i execute following statement
dvGenericNotifications.RowFilter = String.Format("receipientType={0}", ddlType.SelectedValue);

推荐答案

尝试更改为；

dvGenericNotifications.RowFilter = "receipientType=''" + ddlType.SelectedValue.tostring() + "''";

Try changing to;

dvGenericNotifications.RowFilter = "receipientType=''" + ddlType.SelectedValue.tostring() + "''";
