How to exclude last row of grid when sorting any column
I am new to extjs4, and i need help.
I have a data grid which display some records. When we sort data on column wise i sort all the rows of the grid, but I don't want to sort the last record of the grid as it contains different data. Can any one help how to do this.
Actually i am display some data in grid and in last row i am display sum of each row for all the column.
so when sorting the last row should stay at last only.
Now if i sort the last row is shuffling to first row.
Is there a way to override the sorting functionality in store/view, so that i can skip the last row.
Is it possible in this way?
But i have two more concern.
1. How to change the font style and size of the summary row?
2. Suppose a column having data of time [ Example : 1:10 , 0:30 , 2:40 -> sum= 4:20 ], how to calculate sum for this type of data.
