No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

No, our 100 WPF controls, including RichTextBox, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their RichTextBox alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 100 WPF controls for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

We do not sell the WPF RichTextBox control separately. It is only available for purchase as part of the Syncfusion WPF suite, which contains over 100 WPF controls, including RichTextBox. A single developer license for the Syncfusion Essential Studio for WPF suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team to see if you qualify for any additional discounts.
