I have a GridView control that I want to sort on multiple columns when I
click a particular column. For example, I display Last name + ", " + First
name in the first column and display id in the second column. When clicking
on the first column, I want the GridView to sort on LastName and FirstName.
Based on Microsoft's documentation of SortExpression property, all I have to
do is to set SortExpression= LastName,FirstN ame on the first column. But when
the GridView sorts the data, it only applies sorting direction to the second
parameter of the SortExpression. In the above example, if I click on the
first column, the GridView apparently always does sorting by LastName in
ascending order, but the FirstName sort can be either ascending or
descending (depending on whether I clicked the first column once or twice).
I would expect the GridView to sort the entire sort expression on
ascending/descending order, but it looks like the GridView does this only
for the last parameter in the sort expression. Is this a bug or what? 1 3548
If your data is a DataSet, DataTable or DataView, all that the grid is doing
is passing in your SortExpression into the DataView's Sort property and it
appends " DESC" when descending is requested.

I'm getting an error in the following scenario.
- A GridView control is bound to an SQLDataSource.
- The user selects a column for sorting.
- Some time later in code the column used for sorting is removed and the
SelectCommand SQL changed so that the field is not returned.
- When the GridView is redisplayed an error occurs because the
GridView.SortExpression is no longer a valid column.
The SortExpression property of the GridView...

Hi all,
I currently have a Gridview that doess sorting correctly
using several fields. However, I do have a checkbox field
that when it is checked I do not know how to make its
value to persist when the page is sorted after it is changed.
I do handle the checkedchanged event, but I do not know
if it is there that I need to do something with the whole gridview or just
the checkbox that was checked/unchecked.

Hello, I want to implement a generic list which will be used to
display 7 columns in a GridView. One should be able to sort, filter

ascending and descending.
I'm currently using a DataView but it's far too slow, because there

I have a GridView control with three columns, all BoundField columns. They

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
