Image not displaying on a dynamic Table !

Question

Dear Friends,
In my assignment, I would like to display the Status column of a table with different image as per the data received from backend system.
Infact it is a dynamic table generation.  The code snippet is as below:
IWDNodeInfo tabNode=wdContext.getNodeInfo().getChild("Reports_TAB");
String colName="Status";
String imagePath=tabNode.getAttribute(colName).toString();
IWDImage colImage=(IWDImage)view.createElement(IWDImage.class, colName+"Image");
colImage.setSource(imagePath);
But problem, is imagePath is hold the value as DataAttributeInfo(DashBoardView.It_FinalTAB.Status), instead of actual image name.
(Ya, Image is stored in src/mimes/Components/<component>/ folder, which is working absolutely fine with test example.)
Because of this, image is not displaying on the table elements.
Can anybody help me, how can retrive exact image name from the tabNode?
Thanks in advance,
Lakshmikantha

Hi Lakshmikantha,
     Instead of Doing colImage.setSource() you have to do collmage.bindSource()
IWDNodeInfo tabNode=wdContext.getNodeInfo().getChild("Reports_TAB");
String colName="Status";
IWDAttributeInfo imagePath=tabNode.getAttribute(colName);
IWDImage colImage=(IWDImage)view.createElement(IWDImage.class, colName+"Image");
colImage.bindSource(imagePath);
What we have done here is when the table column is created we are mentioning that at runtime for each record the image source has to be taken from the attribute value of "Status". This will only work if at runtime the value coming in the Attribute Status has the image path (relative path).
If for instance you dont have the image path coming from the backend but only the status code and you have to decide which image to show at runtime. This is mostly the case. Then under the node "Reports_TAB" you will have to create a calculated attribute of type String. The calculated attribute will generate a getter method which will accept the current record and return the string. You will have to write code to extract status from the current record and return the appropriate path.
The binding of the Image table column should now point to the newly created calcuated field instead of the field Status.
Hope this helps.
