使用循环来设置Webform中所有RadGrid的属性？

Question

I have several radgrids in my webform and I want to set all the visible property to false without having to specify the control name.

How can I do this with a loop?

Thanks.

Answer 1

Use the jquery.

$("radgrids").prop("visible",false);

This will set all the radgrid element's visible property to false.
Hope this works. Don't forget to add the jQuery library.

Answer 2

There is no automated way to do such a task in .NET

I think you will need a method like FindControlRecursive() that will recursively go through all controls on the page, and it will compare each control type with RadGrid, eg:

protected void Page_Load(object sender, EventArgs e)
{
    for (int i = 0; i < form1.Controls.Count; i++)
    {
        if ((form1.Controls[i]) is RadGrid)
            Response.Write(string.Format("found a grid with ID: {0}<br />", form1.Controls[i].ClientID));
    }
}

where this would need to be recursive, of course to get all controls on the page.
