在行编辑过程中如何在动态添加的控件的Grid的行更新事件中查找值 [英] How to find value in row updating event of Grid of dynamically added control during row editing

问题描述

朋友，


帮助我找出Grid的行更新事件中下拉列表的值.该下拉列表是在行数据绑定事件中的行编辑过程中添加的.

我也尝试过在Row创建的事件中添加相同的控件并绑定相同的数据源.但是我无法进行更新.

(((DropDownList)gvTest.Rows [e.RowIndex] .FindControl("ddl")));值作为null抛出，并抛出未设置为参考错误的对象实例.



请帮助

谢谢

推荐答案

，如果发生do

in the event do

GridViewRow gRow = GriwViewRow(sender);
GridView grid = (GridView)gRow.NamingContainer;
grid.SelectedIndex = gRow.RowIndex;

现在，您可以执行gRow.FindControl(").
最后做

Now you can do a gRow.FindControl("").
at the end do

grid.SelectedIndex = -1;
