1. Grid display page.
2. ColdFusion component and function to bind the grid.
3. JavaScript for changing the color of specific grid Cell.
1. cfgridDemo.cfm(Grid Display Page)
<html>
<head>
<script type="text/javascript" src="./cfgridDemo.js"></script>
</head>
<body>
<!-- This is grid display Order information of a online Shop. orderID, Order Date, Customer Name, Order Status
The order status can be complete, pending, Shipped, etc.Depending on the order status the color of the status text will change
-->
<cfform name="displayGridForm" format="html">
<cfgrid format="html" name="displayGrid" autoWidth="true" pagesize="50" selectmode="row" bind="cfc:testCode.cfgridDemo.getGridData({cfgridpagesize},{cfgridpage},{cfgridsortcolumn},{cfgridsortdirection})" sort="true">
<cfgridcolumn name="ORDERID" width="150" header="Order ID" headerbold="true" />
<cfgridcolumn name="ORDERDATE" width="100" header="Order Date" headerbold="true" type="date" />
<cfgridcolumn name="CUSTOMERFIRSTNAME" width="150" header="Customer First Name" headerbold="true" />
<cfgridcolumn name="CUSTOMERLASTNAME" width="150" header="Customer Last Name" headerbold="true" />
<cfgridcolumn name="ORDERSTATUSID" width="100" header="Order Status ID" headerbold="true" />
<cfgridcolumn name="STATUS" width="100" header="Status" headerbold="true" />
</cfgrid>
</cfform>
<cfset ajaxOnLoad("init") />
</body>
</html>
2. cfgridDemo.cfc(ColdFusion component and function to bind the grid)
<cfcomponent>
<cffunction name="getGridData" access="remote" returntype="Struct" output="false">
<cfargument name="pageSize" required="false" default="30" hint="No of records to display in each page of cfgrid" />
<cfargument name="pageNo" required="false" default="1" hint="Current page no of cfgrid which you want to view" />
<cfargument name="sortColumnName" required="false" default="ORDERID" hint="Default sort column for query sorting" />
<cfargument name="sortDirection" required="false" default="ASC" hint="Default query sort direction" />
<cfset variables.qryGetMedia = queryNew("") />
<!--- Default Sort Coulmn name if the sortColumn contains empty strings --->
<cfif len(arguments.sortColumnName)>
<cfset variables.sortColumnName = arguments.sortColumnName />
<cfelse>
<cfset variables.sortColumnName = "ORDERID" />
</cfif>
<!--- Default Sort direction if the sort direction contains empty string --->
<cfif len(arguments.sortDirection)>
<cfset variables.sortDirection = arguments.sortDirection />
<cfelse>
<cfset variables.sortDirection = "ASC" />
</cfif>
<!--- Here I have used the dafualt datasource created during ColdFusion installation.
So you can run the code directly. --->
<cfquery datasource="cfartgallery" name="variables.qryGetMedia">
SELECT
ORDERS.ORDERID,
ORDERS.CUSTOMERFIRSTNAME,
ORDERS.CUSTOMERLASTNAME,
ORDERS.ORDERSTATUSID,
ORDERS.ORDERDATE,
ORDERSTATUS.STATUS
FROM ORDERS
INNER JOIN ORDERSTATUS ON ORDERS.ORDERSTATUSID = ORDERSTATUS.ORDERSTATUSID
ORDER BY #variables.sortColumnName# #variables.sortDirection#
</cfquery>
<!--- Convert the query Object into cfgrid compatible structure --->
<cfreturn queryConvertForGrid(variables.qryGetMedia, arguments.pageNo, arguments.pageSize) />
</cffunction>
</cfcomponent>
3. cfgridDemo.js(JavaScript for changing the color of specific grid Cell.)
var init = function(){
//get the grid Object
grid = ColdFusion.Grid.getGridObject('displayGrid');
//get grid Column Model
var gridCM = grid.getColumnModel();
//Call the color renderer function to render the color
gridCM.setRenderer(gridCM.getIndexById('STATUS'), colorRenderer);
}
//Function to color renderer
function colorRenderer(value)
{
if(value.search(/paid/i) > -1)
return '<b style="color:#00FF00;">' + value + '</b>';
else if(value.search(/pending/i) > -1)
return '<b style="color:#FF0000;">' + value + '</b>';
else if(value.search(/shipped/i) > -1)
return '<b style="color:#00FFFF;">' + value + '</b>';
else if(value.search(/complete/i) > -1)
return '<b style="color:#0000FF;">' + value + '</b>';
else
return value;
}
After all these steps if we will run cfgridDemo.cfm we will get the following out put. We can also change the display style by changing the JavaScript as I have done.
