如何使用for循环修改多个控件（gridview）

Question

Hello everyone Is it possible to use a for loop to cycle through a set of gridviews and modify each one of them?

Let's say I have 10 gridviews named Gridview1, Gridview2, Gridview3...and so on.

Can i write something like

for(int i=1; i<=10;i++)
{
    Gridview[i].Rows[1]...
}

Hope I was clear enough, sorry for my english.

Answer 1

In your for loop,

for(int i=1; i<=10; i++)
{
    (Page.FindControl("GridView" + i) as GridView).Rows[1]...
}

Answer 2

You can use foreach loop. like this.

        foreach (GridView gv in Page.Controls.OfType<GridView>())
        {
           gv.Rows[1].........
        }

Other approach, if you are using 2.0 version

for(int i=1; i<=10; i++)
{
     ((GridView) Page.FindControl("GridView" + i)).Rows[1].........
}

Provided that you already store your gridviews in a list like this:

List<DataGridView> GridViews = new List<DataGridViews>();

GridViews.Add(myFirstGridView);
GridViews.Add(mySecondGridView);
....
