The last column on a child grid is a delete link, however I only want this link visible if the row was added within the last five minutes (for security purposes). So far I have the following code  working in the rowsExpanded Event. However, if the user makes a change to the grid, causing a grid update, the information is lost.

I can't do this code in the pageLoad because when a grid is updated, the page is not reloaded

Is there any client event that is triggered when a grid does a post back/update? Or is there another way to accomplish this?

var index = eventArgs._props[0]._index;

var grid = ig_controls["ctl00_ContentPlaceHolder1_WebHierarchicalDataGrid1"].get_gridView();

var gridrow = grid._rows._rows[index]

var rowislands = gridrow.get_rowIslands();

var childGrid = rowislands[0];

var totalrows = childGrid._rows._props[0];

for (counter = 0; counter < totalrows; counter++) {

var transdate = childGrid._rows.get_row(counter).get_cellByColumnKey("TransDate").get_value()

var Now = new Date();

diff = transdate-Now

if (diff > -300000) {

var value = childGrid._rows.get_row(counter).get_cellByColumnKey("Delete").get_element()

value.children[0].style.display='block'

}
