The RWA alert may be issued based on processing of the incremental or differential backup metadata to identify candidate new files and candidate deleted files in which the candidate new files are candidates for being encrypted copies of the candidate deleted files. RWA remediation is performed at least in part on the RWA alert being issued. The RWA detection protection includes processing incremental or differential backup metadata acquired during the incremental or differential backup to determine whether a RWA alert is issued. Ransomware attack (RWA) detection is performed during an incremental or differential backup of a system of folders or directories of a computer or network of computers via an electronic network. 6, 2020 and titled “METHODS AND SYSTEMS FOR DETECTING RANSOMWARE ATTACK IN INCREMENTAL BACKUP,” first named inventor Kurt Hansen, is incorporated by reference herein in its entirety. Relative to other techniques, the disclosed systems/methods can decrease the time and/or computational resources required to detect ransomware, while also decreasing false positives and false negatives. Also, according to some embodiments, the disclosed systems and methods compute an entropy associated with an extracted sample of files to distinguish between infected and uninfected file systems. According to some embodiments, the disclosed systems and methods analyze metadata describing the contents of an examined filesystem embodied in a Master File Table (MFT). These systems and methods may enable a computer user to detect a ransomware infection within a filesystem utilizing a snapshot image-based backup. 2018/0107824 discloses, as some illustrative embodiments, systems and methods for detecting ransomware infection in filesystems. 17, 2017 and titled “SYSTEMS AND METHODS FOR DETECTING RANSOMWARE INFECTION”, first named inventor Robert John Gibbons, Jr., is incorporated by reference herein in its entirety. Is a standard de-facto for WPF it can be useful for your app.U.S. Private void FilterByFoutCode(string filter)įoutensDataGrid.ItemsSource = loadedData.Where(x => x.FoutCode = filter) Īlso, in the performance context you should not have extra iteration of your collection via if your filter is not empty then filter loadedData by criteria Private void FilterByFoutCodeButtonClick(object sender, EventArgs e) if you want to filter values immediately you can call filter method right hereįoutensDataGrid.ItemsSource = loadedData here you save unfiltered data to the field and then you can use it to filter collection You can save loaded data in class field and then filter it via handle buttonClicks: Where dateStart = fout.Datum & = trein.NameTrein ObjectQuery fouten = eventsEntities.Foutens But whats the best way to do this?ĭateTime dateStart = () ĭateTime dateEnd = () I could write a new query for this but that seems unnecessary as the data is already available, I just need to filter it.
However I got more wpf controls that are needed to filter the datagrid even more, for example from a time range.

With this code I'm setting my Itemsource of my datagrid.
