Grid Configuration

All you need to do to configure dhtmlxGrid on the server side is to:

create configuration object

var config = new dhtmlxGridConfiguration();

set required parameters

config.SetHeader("Item,#cspan");
config.AttachHeader("Sales,Title");
config.SetColIds("col1,col2");
config.SetInitWidths("120,*");
config.SetColSorting("connector,connector");
config.SetColColor(",#d5f1ff");
config.SetColHidden("false,false");
config.SetColTypes("ro,ed");
config.SetColAlign("center,center");
config.SetColVAlign("bottom,middle");

and attach config to the connector

connector.SetConfig(config);       
return connector;

dhtmlxConfiguration has the following methods:

public string HeaderDelimiter // gets or sets header delimiter
public void SetHeader(string names)//headers names separated by delimiter(','by default)      
public void SetInitWidths(string wp) // sets dhtmlxGrid columns widths in pixels                                                            
public void SetInitWidthsP(string wp) // sets dhtmlxGrid columns widths in percents           
public void SetColAlign(string str) //sets dhtmlxGrid columns horizontal align                
public void SetColVAlign(string str) // sets dhtmlxGrid columns vertical align 
public void SetColTypes(string str) // sets dhtmlxGrid columns types            
public void SetColSorting(string str) // sets dhtmlxGrid columns sorting types
public void SetColColor(string str) // sets dhtmlxGrid columns colors                  
public void SetColHidden(string str) // sets dhtmlxGrid hidden columns         
public void SetColIds(string str) // sets dhtmlxGrid columns ids
 
//attaches dhtmlxGrid header
//"values" - header titles separated by delimiter
//"styles" - header styles separated by delimiter
//"footer"  if true attaches footer  
public void AttachHeader(string values, string styles = null, boolean footer false)  
 
//attaches dhtmlxGrid Footer
//"values" - footer titles separated by delimiter
//"styles" - footer styles separated by delimiter
public void AttachFooter(string values, string styles = null) { 
    AttachHeader(values, styles, true);
}
