Re: Can InfoPath code behind update SharePoint list metadata?

In case if anybody has same problem.

I find out from SPTechCon that it can't be done.

Infopath can't update SharePoint metadata. It can add, but not change the value of metadata.

Hi Jim,

Thank you for your suggestion.

But now I'm getting "Operation is not valid due to the current state of the object." error.

Still it can not update SharePoint data.

I'm executing this while the form is in workflow in case if this makes difference.

Thanks.

Make sure to set AllowUnsafeUpdates on both the SPSite and SPWeb objects

using (SPSite site = new SPSite(tempStrUrl))

{

site.AllowUnsafeUpdates = true;

using (SPWeb web = site.OpenWeb())

{

web.AllowUnsafeUpdates = true;

Can InfoPath code behind update SharePoint list metadata?

Hi,

I'm trying to update one of field in SharePoint list using code behind from InfoPath form. With below code, I'm getting The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again. I tried additional code with commented out statements too, but same problem.

Is it possible to update SharePoint metadata from InfoPath code behind? I can upload/create new list and delete wihtout a problem, but update fails.

Thanks.

string tempStrUrl = http://server;

string listName = "LibName";

string fileName = "xyz.txt";

SPSecurity.RunWithElevatedPrivileges(delegate()

{

using (SPWeb site = new SPSite(tempStrUrl).OpenWeb())

{

//Microsoft.SharePoint.Administration.SPWebApplication webApp = site.Site.WebApplication;

//webApp.FormDigestSettings.Enabled = false;

site.AllowUnsafeUpdates = true;

tempLocation = tempStrUrl + "/" + listName + "/" + fileName;

try

{

SPListItem item = site.GetListItem(tempLocation);if (null != item)

{

item["Status"] = "Finalize";

//item.SystemUpdate();

item.Update();

}

catch (Exception ex)

{

string v = ex.Message;

}

//webApp.FormDigestSettings.Enabled = true;site.AllowUnsafeUpdates = false;

}

});
