删除方法应用于目标数据 源的DeleteCommand会
公共无效DeleteUserAchievementInfo（UserAchivementInfoBO BOInstance）
{
尝试
{
Int64的UserAchievementInfoId = BOInstance.UserAchievementInfoId
objUserBasicInfoServiceClient.DeleteUserAchievementInfo（UserAchievementInfoId）;
}
赶上（例外前）
{
HandleException.LogError（前）;
}
}
尝试添加的业务对象键字段（如身份证，钥匙......）到ListView DataKeyNames属性。通过这样做，你至少可以得到在删除事件的核心价值。
i have one Listview in my Usercontrol & 1 objectdatasource binded with the ListView. now in objectdatasource's Deletemethod i have taken businessobject as argument but at runtime i am not getting value in my businessobject's properties...
i also tried to use "Bind" instead of "eval" in ItemTemplate. but not getting any value at runtime in my DeleteMethod provided in objectdatasource's Deletecommand... can anybody help to know weather i am mising anything or what?
my Listview's ItemTemplate
<ItemTemplate>
<asp:HiddenField ID="hidUserAchievementInfoId" runat="server" Value='<%# Bind("UserAchievementInfoId") %>' />
<asp:HiddenField ID="hidUserIdField" runat="server" Value='<%# Bind("UserId") %>' />
<tr>
<td class="style1">
<asp:Label ID="AwardLabel" runat="server" Text="Award "></asp:Label>
</td>
<td>
<asp:Label ID="lblAward" runat="server" Text='<%# Bind("Awards") %>'></asp:Label>
</td>
</tr>
<tr>
<td class="style1">
<asp:Label ID="FieldofAwardLabel" runat="server" Text="Field of Award "></asp:Label>
</td>
<td>
<asp:Label ID="lblFieldofAward" runat="server" Text='<%# Bind("FieldofAward") %>'></asp:Label>
</td>

</ItemTemplate>
Delete Method used in objectdata source's Deletecommand
public void DeleteUserAchievementInfo(UserAchivementInfoBO BOInstance)
{
try
{
Int64 UserAchievementInfoId=BOInstance.UserAchievementInfoId
objUserBasicInfoServiceClient.DeleteUserAchievementInfo(UserAchievementInfoId);
}
catch (Exception ex)
{
HandleException.LogError(ex);
}
}
Try to add the business object key field(e.g id, key...) to the listview datakeynames property. By doing this, you can at least get the key value in the deleting event.
