programatically creating FilterDescriptorCollection

[Todd Millett]

Is is possible to create a FilterDescriptorCollection programatically without the filter control available on the grid, so that  on certain operations the collection is created and bind to the grid so the grid is filtered automatically. Can you share a sample of the same?

Hello Todd Millett,

This is totally possible. However you don't need to actually create the collection, since RadGridView.FilterDescriptors has not setter (it is a collection after all).

Simply start adding your FilterDescriptors to the RadGridView.FilterDescriptors collection.

I believe that my blog post will shed a lot of light on this subject.

Let me know if you have any questions after covering the blog.

Kind regards,

Is there any way i can apply multiple values for a column as a filter criteria. Example : take a column name "UserType", it can contain values like "Dev", "Test", "Tech", "QA".... I want to generate a filter criteria programatically, so that on load only the "Dev", "Tech" and "QA" would be displayed, but any time, user can select the option "Test" from the filter control and repopulate the grid.

Hi Todd Millett,

Yes, you can. This is clearly explained in the blog that I mentioned.

Please read it carefully.
