You can used repeater. Defined images tag and hidden field are stored primary key value.

This is not possible without setting a PK (primary key) field. This will allow you to identify each column uniquely. If you don't know the ID for the row then set 2 (two) PKs.

WHATS NEXT?
Now you can pick the ImageName from a data control like gridview, datalist or repeater, whenever the ImageName is collected you just have to check the same row for column ID and use it to get the countRate or maybe pick countRate directly from the datarow in the control.

Hope this helps
