Use the FilterBarCaption property to change the caption of the control's filter bar. Use the FilterBarForeColor and FilterBarBackColor properties to define the colors used to paint the description for control's filter. Use the FilterBarHeight property to specify the height of the control's filter bar window. If the FilterBarCaption property is empty, the control builds the filter bar's caption based on filtered columns. For instance, if the control filters items based on the columns "Name" and "Value", the control's filter bar caption could be like "[Name] = 'name' and [Value]  = 'value'". Use the Description property to define predefined strings in the filter bar caption. Use the FilterBarFont property to specify the font for the control's filter bar.  

The FilterBarCaption property supports HTML format as described here:

• <b>  bold </b> bolds a part of the caption.
• <u> underline </u> specifies that the portion should appear as underlined. 
• <s> strikeout </s> specifies that the portion should appear as strikeout. 
• <i> italic </i> specifies that the portion should appear as italic. 
• <fgcolor=FF0000>fgcolor</fgcolor> changes the foreground color for a portion.
• <bgcolor=FF0000>bgcolor</bgcolor> changes the background color for a portion.
• <br> breaks a line.
• <solidline> draws a solid line. If has no effect for a single line caption.
• <dotline> draws a dotted line. If has no effect for a single line caption.
• <upline> draws the line to the top of the text line
• <r> aligns the rest of the text line to the right side. It has no effect if the caption contains a single line.
• <img>number[:width]</img> inserts an icon inside the cell's caption. The number indicates the index of the icon being inserted. The last 7 bits in the high significant byte of the number expression indicates the identifier of the skin being used to paint the object. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the part. The width is optional and indicates the width of the icon being inserted. Using the width option you can overwrite multiple icons getting a nice effect. By default, if the width field is missing, the width is 18 pixels.
• <img>key[:width]</img> inserts a custom size picture being loaded using the HTMLPicture property. The Key parameter indicates the key of the picture being displayed. The Width parameter indicates a custom size, if you require to stretch the picture, else the original size of the picture is used
• <font face;size>text </font> displays portions of text with a different font and/or different size. For instance, the <font Tahoma;12>bit</font> draws the bit text using the Tahoma font, on size 12 pt. If the name of the font is missing, and instead size is present, the current font is used with a different size. For instance, <font ;12>bit</font> displays the bit text using the current font, but with a different size.
• & glyph characters as &amp ( & ), &lt ( < ), &gt ( > ), &qout ( " ), &#number, For instance, the &#8364 displays the EUR character, in UNICODE configuration. The & ampersand is only recognized as markup when it is followed by a known letter or a # character and a digit. For instance if you want to display <b>bold</b> in HTML caption you can use &lt;b&gt;bold&lt;/b&gt;
