Exporting Datagrid To Excel Not Showing Color Of Datacell Contents?
Dec 9, 2010I am exporting an ASP.NET datagrid to excel and having an issue with the colors exporting with it. I know in order for the cells color to be exported to excel you must set the background color of the cell. I have several lines of text in the cell, parts of the text are wrapped in a div and the div background color is set. This is the color I need exported. Is there a way to do this? I have included an example below of what would be found in a cell.
<div style="background-color: #b88eb5;>
Random Text 1
</div>
<div style="background-color: #8ccb83;>
Random Text 2

Forms Data Controls :: Datagrid View Control Producing Duplicate Data Results When Data Is Cached?
Oct 10, 2010I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.
