We often select a group of data in the DataGrid and Perform Batch operations. If you want to perform all operations, you need a select all function, if you use the server-side event of the Select All button to select all the check boxes in the DataGrid, It will be returned to the server one more time. We can write a JS function to simplify this step. In fact, the DataGrid will generate an HTML table on the client. The ID attribute of the table is the

By test instructions can know r>=n, I originally thought is first to take n all permutations, the remaining r-n each has n in the choice, so the result is n!*n^ (r-n). God guesses that this will be repeated. For example, 1 to 5 balls, ABC three boxes, MSPaint open the artboard.C Box first put 5 and put 2 (345, after C square 2;342 after C Party 5), so repeat.Allowed to repeat the combination is C (n+r-1,r), allowing the repetition of the arrangement w
