Export DataTable to Excel in Asp.Net without using excel interop – Part II

In my earlier post i have shown a way to export a datatable  as a excel document. But when we open the exported document, the data and all would be as expected but the gridlines that excel displays by default would be hidden. So again see these the user had to go to ribbon View Tab and should check the GridLines Checkbox to view those gridlines. But my reuirement was to enable them by default so that user would be comfortable as it would be the defaukt behavior of excel. Also I had to set the worksheet name. So to achive these two functionalities I had to modify the method “ExportToExcel” from my previous implementation.

Export DataTable to Excel in Asp.Net with sorting/filtering support without using excel interop

Recently I had a requirement for exporting a datatable to excel. This looks fairly simple to do as microsoft provides interop api to automate generation of excel, but the issue I had was I cannot use the interop api on the hosting I currently have. Another option i had was to generate the excel document using the OpenXML, but my requirement is to support even excel 2003 so this option is ruled out. Knowing the fact that excel can interpret Html table and render contents, I started of by generating equivalent Html table for the datatable and writing the content back with content type of excel. So this document can be opened using excel by default, but the only issue is it shows up a warning before opening. Later I also had a requiremnet to have Sorting/Filtering features which normally exists for a default table in excel. This was a bit tricky. Below is the source code walkthrough: Read the rest of this entry »

Export data from ASP.NET application to WORD Document

Here is an article which explains how to insert data into word document using asp.net application, I was searching on net for exporting data into word but most of them (almost all of them) where using Response.Write and setting the content header type to word which will save the content to word document but we will not have full control on the exported content, i.e. it will be very difficult to control the styling of exported text.

CSS Tip – DIV 100 percent height

I always use to think how i can make height of div 100% as i can do this with table, but today suddenly/accidentally when i have given min-height as 100% to div it worked
Then i tracked how this worked, this works only when parent container height is 100%, after doing this i found a scrollbar on the page with div of 100 percent height and made margin to ’0px’ for body and html tags then it was a complete div with 100 percent height

Advanced Repeater – Basic Version with Paging, Filtering and Flexible Page Size

In this article i would like to introduce the Repeater Control with advanced features such as Pagination, Filtering and Flexible Page Size Setting. As Title suggests this is Basic version of Control “Advanced Repeater”. I am planning to write another article of Advanced Version of Advanced Repeater which will be having all basic features plus added features like Re-Ordering Columns, Sorting and few more features.

As many of us say its to better to go for a repeater rather than a gridview in asp.net because gridview supports paging sorting etc.. and we all know that performance wise repeater is far more better than gridview. So i’ve tried implementing the major functionalities which girdview supports using Repeater. Hence this solution “Advanced Repeater”
