在向网格中插入新行之前执行的功能是什么 [英] What is the function that performed before insert a new row to grid

问题描述

大家好:)

我有一个网格，我想为我的插入和更新参数获取一些默认值

我可以使用哪个功能来执行此类操作?

例如:

我有这个广告"表
[Ad_ID] int
[Ad_Title] nvarchar
[Ad_Text] nvarchar
[Ad_Date]日期
[Ad_Time]时间
[Ad_AdminID] int
[Ad_StartDate]日期
[Ad_EndDate]日期
[Ad_FlagISActive]位
[Ad_PhotoPath] nvarchar
[Ad_Language] char

粗体"[Ad_PhotoPath]"列是图像的路径

当我插入或更新一行时，我在编辑模板模式下使用fileupload控件

但是我无法在插入或更新文件之前将文件名添加到路径中

因此，请任何人告诉我在插入或更新行之前可以用来添加文件名的功能吗?

如果还有其他方法可以解决，请告诉我



谢谢大家:)

Hi all :)

I have a grid, and I want to get some default values to my insert and update parameters

which function can I use to do some thing like this ?

for example:

I have this "Ads" table
[Ad_ID] int
[Ad_Title] nvarchar
[Ad_Text] nvarchar
[Ad_Date] date
[Ad_Time] time
[Ad_AdminID] int
[Ad_StartDate] date
[Ad_EndDate] date
[Ad_FlagISActive] bit
[Ad_PhotoPath] nvarchar
[Ad_Language] char

the column in bold "[Ad_PhotoPath]" is the path of an image

when I insert or update a row, I use fileupload control in the edit template mode

but I can''t add the file name to the path before I insert or update it

so please any one can tell me what the function that I can use to add the file name before insert or update the row ?

if there is any other way to do that please let me know



thank you all :)

Gried View Row数据绑定事件很有用:OnRowDataBound
此处，您可以找到有关OnRowDataBound事件的更多信息
还要查看此示例

Gried View Row data bound event : OnRowDataBound
Here you can find more information about OnRowDataBound event
Also look at this Example

使用Gridview_RowDataBound事件.具体取决于我们可以通过在gridview_rowdatabound中调用另一列的值来更改另一列的值.

Use Gridview_RowDataBound event .Depending on value of one column we can change the value of other column by calling it in gridview_rowdatabound.
