datagrid

问题 I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load? These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired. 回答1: Request.Form["__EVENTTARGET"] and Request.Form["__EVENTARGUMENT"] will give the object causing the post back and the event argument. If the data grid does not cause the postback, then there is likely a value

The problem I've run into is that all the headers must have unique names, because myGrid.Columns[x].Header value is tied directly to the column name of the underlying DataTable (where, obviously, no duplicate column names are allowed). Is there any sensible workaround? 回答1: Following code is untested... For DataGridHeaders to be changed, you would have to

Thanks in advance! 回答1: For #1, take a look at Ilya Tumanov's example of custom formatting data in the DataGrid. He does custom painting of cells in it. THis is how you'd "highlight" a row. For #2, there's something wrong with your environment. I've not seen this or heard it reported and I've been
