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!

What are you attempting to validate?  You need to be a little more specific in order to get detailed code.  Here's one way of looping through all of the cells in a column:

For Each row As Infragistics.Win.UltraWinGrid.UltraGridRow In UltraGrid1.Rows
      ValidateCell(row.Cells("TheColumnKey"))
Next

Private Sub ValidateCell(Byval Cell As Infragistics.Win.UltraWinGrid.UltraGridCell)
..
..Do validating here
..
End Sub

What you said helps. Now how can the cell(s) be highlighted for correction?
 
06.07.2007 at 08:42AM PDT, ID: 19234543
Given the following:

      For Each c As Infragistics.Win.UltraWinGrid.CellUIElement In row.Cells
            'some code goes here
      Next

Infragistics.Win.UltraWinGrid.CellUIElement may not be used correctly. How can we loop thru the  row.Cells collection?
 
06.07.2007 at 09:10AM PDT, ID: 19234798
You can highlight cells by modifying the cell's Appearance property.  And to successfully loop through all the cells, instead of using Infragistics.Win.UltraWinGrid.CellUIElement, use Infragistics.Win.UltraWinGrid.UltraGridCell

For Each c As Infragistics.Win.UltraWinGrid.UltraGridCell In row.Cells
      'some code goes here
   c.Appearance.BackColor = Color.Red   '<--Changes the background of the cell to red
Next

I have a utility function that displays a error marker next to a webcontrol. I have used it with textboxes but don't know how to use it with  Infragistics.Win.UltraWinGrid. How can I put an error marker on the left of a row.
 
06.07.2007 at 01:43PM PDT, ID: 19237211
We're starting to deviate from the original question, but you can change the appearance of the row selector (make sure they're turned on) per row like this...assuming you have an error image file located at C:\Images\Error.ICO:

UltraGrid1.Rows(0).RowSelectorAppearance.Image = Image.FromFile("C:\Images\Error.ICO")

 
06.08.2007 at 08:01AM PDT, ID: 19242647
For rows that are good and don't cause errors, I guess I need to do the following:

UltraGrid1.Rows(0).RowSelectorAppearance.Image = ""

Please confirm if that's true.
Thanks.
 
06.08.2007 at 08:19AM PDT, ID: 19242821
Setting it to "" will just be assigning it an empty string for an Image...which works, but I believe a more accepted approach would be:

UltraGrid1.Rows(0).RowSelectorAppearance.Image = Nothing
Accepted Solution
