点击Repeater中的按钮，获取Repeater中TextBox中的值

1.在Repeater_ItemDataBound事件中设置按钮的CommandArgument。代码如下：

         if  (e.Item.ItemType  ==  ListItemType.Item  ||  e.Item.ItemType  ==  ListItemType.AlternatingItem)
        {
            DataRowView dv  =  (DataRowView)e.Item.DataItem;
            ((LinkButton)e.Item.FindControl( " editBtn " )).CommandArgument  =  dv.Row[ " ID " ].ToString()  +   " $ "   +  e.Item.ItemIndex.ToString();
            ((LinkButton)e.Item.FindControl( " delBtn " )).CommandArgument  =  dv.Row[ " ID " ].ToString()  +   " $ "   +  e.Item.ItemIndex.ToString();
        }

 2.在Repeater_ItemCommand事件中获取值，代码如下：

         if  (e.CommandName  ==   " edt " )
        {
             string [] ca  =  e.CommandArgument.ToString().Split( ' $ ' );
             int  itemIndex  =  Convert.ToInt32(ca[ 1 ]);
            TextBox ClassTitleTextBox  =   this .Repeater1.Items[itemIndex].FindControl( " ClassTitle " )  as  TextBox;
             string  ClassTitle  =  ClassTitleTextBox.Text;
        }
