[Solved] Allow filter on Column GridNumericColumn with special characters

[Fernando]

I'm doing a personalized filter, that allow the use of specials characters. How for example ">1"  = "greater that one", this can be done in any column, of any type, numeric, date, string, etc.

But at the that i could perceive, the column filter GridNumericColumn not allow non-numeric characters.

I wonder if there is any way to make the filter a column of type GridNumericColumn allow the entry of some special characters.

This is possible?

Thank you.

Hi Fernando,

Currently there is no way of achieving the desired functionality for two reasons:

1. The filter text box is actually a RadNumericText box and it does not allow non-numeric values.
2. The gird escapes the special character for security reasons. More information on this subject you can find in this forum thread.

You can replace the filter text box with a RadTextBox and exclude the special character from the IllegalStrings collection but that will cause a security vulnerability and is not recommended.

All the best,
