嵌套的GridView-如何触发子GridView Button单击事件 [英] Nested GridView - How to trigger the Child GridView Button Click event

问题描述

我需要在页面中显示主数据/子数据，并且我使用了多个GridView来实现相同的目的.因此，我创建了两个GridView(父级和子级)，现在我想从子级Gridview控件中触发Button单击事件(即btnLock)，并执行一些数据库操作.所以，我不知道该怎么实现.

请帮忙.

I need to show a Master/Child data in a page and I have used multiple GridViews to achieve the same. So, I have created two GridViews (Parent & Child) and now I want to fire the Button click event (i.e. btnLock) from the child gridview control and do some DB operations. So, I dont know how to achieve this.

Please help.

Hi Ragasai,

Go to design mode of your aspx page and then click on edit item templates of parent gridview and drilldown until you find your child grid and then click on edit item templates of child gridview and select btnLock and raise event.


希望这会有所帮助，
