How to save per user/machine?

[John Reynolds]

We've been using the GridSettingsPersister provided in the help here.

What must be done to save the settings per user or per machine in a similar fashion with the new persistence framework?

Regards,

John

Hi John,

Find attached a sample application which demonstrates possible approach for achieving the required functionality.

I hope this helps.

Hello,

FYI, in your example there isn't used the Expires property, that's why a cookie persists only during session. That means, when user closes browser and start app again, the cookie is lost.

If you want to have cookie persisted, just add line marked bold:

public void SaveStateToStorage(string key, string serializedState)
    {
        HttpCookie cookie = new HttpCookie(StorageKey);
        cookie.Expires = DateTime.Now.AddYears(1);
        string settingsData = CompressString(serializedState);

        if (settingsData.Length > MaxCookieSize)
        {
            throw new ArgumentOutOfRangeException("Current settings exceed 4k in compressed form! Operation canceled!");
        }

        cookie.Value = settingsData;

        HttpContext.Current.Response.Cookies.Add(cookie);
    }

Best regards
