coro not populating after update

Response.Write("<column width=“75” id=“state” type=“coro” align=“left” sort=“str”>" State);

Response.Write("<option value=“0”>Active");

Response.Write("<option value=“1”>Inactive");

Response.Write("");



Iam using the above code to define a column of type coro. I have an onafterupdate event defined in my code and in that i reload the grid using grid.loadXML(‘get.aspx’). The problem is that the grid loads fine initially when the page loads but when i try to reload the grid after save the column of type coro is empty. What could be the possible reasons for this strange behaviour?

Please be sure to call
grid.clearAll(true)
before full grid reloading, without such command reloading grid structure may ignore some parameters
