Hi guys,

 

I made a custom module which is used to calculate some data. The view.ascx as 3 fields. 2 textboxes and 1 dropdowlist. The dropdown is poputaled from a table called brokers using a sqlconnection from the connection string from web.config. The table contains broker name and commission rate. The dropdown displays the broker name but the commission rate is the underlying value.

 

Every thing works fine but if 2 brokers have the same commission rate, after the calculation has been done in the button click event, the drop down shoots back to the first broker name with the same value. If some can help me out in this it will be of great help.  Thanks

 

Amith

You cannot have multiple items in a dropdown list with the same value since setting the SelectedValue property will always reset the DDL to the first item with that value. It also causes problems with retaining the selection through postbacks which is what's happening here.

If you are not able to use a control other than a DropDownList, etc. for selection of the broker, you might try disabling v13wstat3 for the dropdown list then in Page_Load rebinding the list on every page load, then re-selecting the broker using the FindByText method of the DDL's Items collection. You will, of cource, need to maintain the previously selected broker's name through v13wstat3 or some other persistence mechanism.
