RowDataBound - 当数据绑定到该行时，为网格中的每一行调用事件。

这也包括你的标题。



你可以使用此事件来获取绑定时的数据值。应用你的逻辑。

Ex。如果要求对于特定列值大于50，则使用RED& BOLD字体。



您应该非常小心使用此事件，因为大量数据会导致性能问题，因为每个行都会调用事件。如果你添加要在每一行执行的逻辑..它将需要更多时间...

RowDataBound - Is event getting called for each row in grid when data is binding to that row.
This include your header also.

You can use this event to get the data values at the time of binding & apply your logic.
For Ex. If there is requirement that if for perticular column values is greater than 50 render the value with RED & BOLD font.

You should be very carefull using this event because large amount of data will cause performance issue as the event will be called for every row & if you add logic to be performed on every row.. it will require more time...
