Datagrid sort event handler does not get fired
when dynamically creating/adding/removing columns to the datagrid

Thanks in advance for your answers

Arun

You probably need to put the sort event handler in your code-behind,
probably in your Page_Init:

DataGrid1.SortCommand += new
DataGridSortCommandEventHandler(DataGrid1_SortCommand);

Hi Arun,

I got your emails with the code that you used for creating the datagrid. 
Let’s continue the discussion on the forum.

You can search for previous threads where we discussed the issues to watch
for regarding dynamically created controls and the page lifecycle.  In
particular as it relates to the dependency of the function of those controls
on their ViewState.  Look in this article for the phases in which the
ViewState is loaded and saved:

In your sample (whose code you emailed me) you can get it to work if you
were to move the databind from the button click event handling to the page
initialization (for one datagrid only in your case).  Once you see that, you
have to think of a different strategy to creating your DataGrid first (during
page.init) then sorting it (by re-binding the created controls to the new
sorted dataview) upon button click.

In other words, separate the DataBind method that you have into 2 methods;
1) one that adds the boundcolumns according to the DataTable structure and
adds the event handlers, 2)  another that databinds the data after sorting it
based on the selected sort key.
