The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

DataBinding: 'System.String' does not contain a property with the name

Asked by nanditab10 in Microsoft Applications, Microsoft Development, Programming for ASP.NET

Tags: ASP.net, vb.net

I am getting the error below :

when trying to bind the listbox with the Arraylist..  on this line :
Me.lstMPIN.DataBind()

DataBinding: 'System.String' does not contain a property with the name 'MPIN'.

The listbox  is initially populated with the code below on page load
 Me.SqlDataSourceUserList.ConnectionString = ConfigurationManager.ConnectionStrings("PPMConnectionString").ConnectionString
        Me.SqlDataSourceUserList.SelectCommand = "SELECT distinct [Srvc_Mpin] as MPIN FROM  " & varPrepTblname & " where SRC_SYS_GRP_RLLP_DESC in ('UNET','MAMSI','RV','RIMS','OHP','NICE','ILIAD','LIVE') order by [Srvc_Mpin] "
        lstMPIN.DataSource = Me.SqlDataSourceUserList
        lstMPIN.DataTextField = "MPIN"


And then later on  I read the content of the listbox in a arraylist.. and need to repopulate the listbox with that arraylist .. the reason I am doing is I need to use the sort feature of the array..

        Dim alItems_MPIN As New ArrayList()
        For Each lst As ListItem In Me.lstMPIN.Items
            alItems_MPIN.Add(lst.Text)
        Next
        alItems_MPIN.Sort()

        lstMPIN.DataSource = ""

        Me.lstMPIN.DataSource = alItems_MPIN
        Me.lstMPIN.DataTextField = "MPIN"
        Me.lstMPIN.DataBind()

any help Please ?
