I'm experiencing the a challenge in populating the child records. 
My previous code was like -

```
<%= Html.TextBox("DyeOrder.Summary[" + i + "].Ratio", Model.DyeOrder.Summary[i].Ratio.ToString("#0.00"), ratioProperties)  %>

```

This code does not render the updated values after post back. To resolve this issue my work around was like - 

```
<%= "<input id='DyeOrder_Summary_" + i + "__Ratio' name='DyeOrder.Summary[" + i + "].Ratio'  value='" + Model.DyeOrder.Summary[i].Ratio.ToString("#0.00") + "' " + ratioCss + "  type='text' />"%>

```

This is very clumsy to me. Is there any better ideas...
