Question

If I used remapColumns in columnChooser‘s done event, then I don’t have problem to sort the columns. But when I moved
remapColumns to beforeRequest with a new perm information, see below:

beforeRequest: function(){                                              
    perm =   {0:2,1:0,2:1,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10};
    myGrid.jqGrid("remapColumns", perm,  true);
}

The columns are correctly reordered, and I can search column value, but the column sorting function was just disabled. The click event seems not working. Can somebody help? How can I get it back?
Really appreciate it.

Thanks very much!

Answer 1

In the answer you can find an example how to use remapColumns and I hope another helpful information for you. In the demo I use remapColumns once inside of loadComplete. I don’t understand why you want to change the column order on every request to the server.

UPDATED: The modified demo don’t have the effect which you described. The reason was that one called in the old demo the method remapColumns with empty ([]) permutation parameter and remapColumns works incorrect in the case. So I included additional test for myColumnsState.permutation.length > 0.

UPDATED 2: Free jqGrid provides the method remapColumnsByName additionally to remapColumns. The first parameter of remapColumnsByName is array of column names, which should be on the grid. Columns "subgrid", "cb" and "rn" could be included or not. The understanding of the usage of remapColumnsByName is much more easy as the usage of remapColumns especially in situations where the order of columns could be changes by the user (by columnChooser, wor example). It’s strictly recommended to use remapColumnsByName instead of remapColumns.
