I have a page that has two data grids.  One displays authors and when the author is selected all of the books written by that author are displayed on the same page.  The user can then select all or some of the books and submit a request for those selected books to be pulled by the librarian.

My question is how do I get the second grid to be hidden when the page loads?  The client want to be able to collapse and expand/hide or show the second grid.

My code for the grids
     <div>
        <asp:GridView runat="server" ID="gvBooks" DataSourceID="Books_ds" />
        <asp:GridView runat="server" ID="gAuthorss" DataSourceID="Authors_ds" AutoGenerateSelectButton="true" DataKeyNames="AuthorName" />     
    </div>

Open in new window


My code  behind
    public static List<AuthorSelection> GetAuthorList()
    {
        List<AuthorSelection> Authors = new List<AuthorSelection>();
        SearchResultCollection src = ds.FindAll();

        foreach (SearchResult sr in src)
        {
            if (!sr.Properties.Contains("msexchhidefromaddresslists") || (sr.Properties["msexchhidefromaddresslists"][0].ToString() != "True"))
            {
                AuthorSelection auths = new AuthorSelection();
                if (sr.Properties.Contains("authorname")) gs._name = sr.Properties["authorname"][0].ToString();
                if (sr.Properties.Contains("displayedauthname")) gs._display = sr.Properties["displayedauthname"][0].ToString();
        Authors.Add(gs);
            }

        }
        return Authors;

I would think that you need some way to store the state of the show/hide for the second grid.  In the Page_Load event handler, you could then set the GridView.Visible property to the current state for the show/hide.

You could use a ViewState variable or a CheckBox.

In the Page_Load, it would be something like this:

protected void Page_Load(object sender, EventArgs e)
{
     gvAuthors.Visible = (ShowHideSecondGrid.Checked);
}
