当Grid加载时，有没有办法在GridView上自动执行'Select'命令？

Question

我有一个GridView谁是基于另一个GridView的SelectedValue的DataSource SELECT。

在GridView上使用SelectedValue（DataKeyName），我需要在网格加载时执行Select命令，而不是使用“选择”按钮。

我尝试过使用GridView的SelectedIndex属性，但这不会对我有用。 我也看过各种各样的方法和事件，但我似乎找不到这样做的好方法。

在下面的代码中，有一个带有“选择”按钮的ButtonField，但我想在填充网格时或之后进行选择命令。

提前致谢。
