Conditional statement for Repeater Controll in ASP.NET - asp.net

Question

I am populating some data in a table with 6 columns using a repeater control in ASP.NET (VB) using the enclosed code.
I want a piece of code to achieve the following functionality by attaching an if/elseif/else condition to the repeater controll:
For the record with<%#Eval("SOLID")%> = "40103" then the data to be displayed in one cell, merging all 6 columns in to one (ideally using colspan = 6).
For the record having <%#Eval("SOLID")%> = "40105" then the data to be displayed in two cell, merging the second and third column.
For all the other records the data to be displayed in the actual format.
I have gone through various sites for a solution, but in vain. Please help me

To achieve this you can write your logic in the ItemDataBound event of the Repeater control. You will need to get references of your table cells and labels, then set your colspan, merge your label values, and hide any extra cells.
