Question

Have a fun issue with sharepoint calendar view filtering.
That code works fine:

SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite siteCollection = new SPSite(SPContext.Current.Web.Site.ID))
                {
                    using (SPWeb site = siteCollection.OpenWeb())
                    {
                        site.AllowUnsafeUpdates = true;
                        SPView view = site.Lists["My Calendar"].Views["Calendar"];
                        view.Query = @"<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>ololo</Value></Eq></Where>";
                        view.Update();
                        site.AllowUnsafeUpdates = false;
                    }
                }
            });

But when I change query to

SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite siteCollection = new SPSite(SPContext.Current.Web.Site.ID))
                {
                    using (SPWeb site = siteCollection.OpenWeb())
                    {
                        site.AllowUnsafeUpdates = true;
                        SPView view = site.Lists["My Calendar"].Views["Calendar"];
                        view.Query = @"<Where><Or><Eq><FieldRef Name='Title'/><Value Type='Text'>ololo</Value></Eq><Eq><FieldRef Name='Title'/><Value Type='Text'>trololo</Value></Eq></Or></Where>";
                        view.Update();
                        site.AllowUnsafeUpdates = false;
                    }
                }
            });

I get exception:

Input string was not in a correct format.

Does anybody know how fix that problem?

Answer 1

The problem is solved. “DateRangesOverlap” should be added to the calendar query.

view.Query = @"<Where><And><DateRangesOverlap>
    <FieldRef Name='EventDate' />
    <FieldRef Name='EndDate' />
    <FieldRef Name='RecurrenceID' />
    <Value Type='DateTime'><Month /></Value>
</DateRangesOverlap>
<Or><Eq><FieldRef Name='Title' />
<Value Type='Text'>orlolo</Value></Eq>
<Eq><FieldRef Name='Title' />
<Value Type='Text'>trololo</Value></Eq>
</Or></And></Where>";
