  1. How do I configure header filter as case sensitive?

  2. How do filter the integer column like typing “>500” or “<500” or “>=500”

This is my code

		Response.Write("<beforeInit>")
			Response.Write("<call command='attachHeader'>")
			Response.Write("<param>")
				Response.Write("#text_filter,#text_filter,#text_filter")
			Response.Write("</param>")
			Response.Write("</call>")
		Response.Write("</beforeInit>")

		Response.write("<column id='column1' width='100' type='ro' align='center' sort='str'>")
			Response.write("") 
		Response.write("</column>")
		Response.write("<column id='column2' width='100' type='ro' align='center' sort='str'>")
			Response.write("") 
		Response.write("</column>")
		Response.write("<column id='column3' width='100' type='ro' align='center' sort='str'>")
			Response.write("") 
		Response.write("</column>")

  1. It can be done only with custom filter in the header. You can use filterBy() method to filter grid in any way you need
  2. Try to use #numeric_filter type of filter
