<p>Ours is an upcoming company, so we cannot buy two three third party controls and find out by ourselves which the best one is.(One of the better solutions)
We have a budget to buy just one.
So we would like to know which is third party control is the best to use in ASP.NET based on your experiences.</p>
<p>And also I definitely saw a question asked already here.</p>
<p><a href="https://stackoverflow.com/questions/215993/best-3rd-party-aspnet-grid-control">https://stackoverflow.com/questions/215993/best-3rd-party-aspnet-grid-control</a></p>
<p>Still asking this because</p>
<ol>
<li>Wanna know not just about grid, i wanna know about the whole set.</li>
<li>Didn't see many answers for that.</li>
</ol>
<p>So please provide us some advice on how to proceed.
Our requirements are</p>
<ol>
<li>Bug Free working</li>
<li>Speed</li>
<li>Good documentation</li>
<li>Excellent Support Team</li>
</ol>
<p>Also is there a third party ListView?</p>
<p>Regards,</p>

For all those requirements, there's only two companies to choose from:
Telerik
and
DevExpress
.  Both have fantastic support and incredible ASP.NET products.  They release often, and are known to be constantly adding new controls.  I had to decide between the two about a year ago, and went with DevExpress because of the productivity tools included.
The difference I see between these two companies and larger competitors like Infragistics is they are dedicated to making the best quality and best performing products possible.
