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!

how do I resize Gridview columns to keep data from wrapping programmatically?

Asked by bd9000 in Programming for ASP.NET, Microsoft Visual Basic.Net

Tags:

I'm having a hair puller with the GridView in ASP.Net (2.0) getting it to NOT wrap the data in the columns.
I set all the templates to WRAP=FALSE, with no effect in Internet Exploder 7.  FireFox does not wrap the text, so it works like it should.
I tried to access the data as it is being bound to the gridview (from a DataSet) and set the width dynamically depending on the data for each column.  This just generates an index out of range error on the Columns() property, no matter what the ordinal (I suppose the column(s) in the GridView could not be accessed by ordinal because it hadn't been created yet - a Catch-22).

The example below should determine the width of the data in characters, determine the pixels needed, and turn off wrapping (i borrowed this from MS KB, but it won't work).
Any ideas on how to make this work? Start Free Trial

Protected widestdata As Integer = 0
 
Protected Sub gvSpreadSheetRawData_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvSpreadSheetRawData.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  
            Dim drv As DataRowView = DirectCast(e.Row.DataItem, DataRowView)
            Dim cc As Integer = e.Row.Cells.Count
            For x As Int16 = 0 To cc - 1
                Dim itemlen As Integer = drv.Item(x).ToString.Length
                   If itemlen > widestdata Then
                        widestdata = itemlen
                        Me.gvSpreadSheetRawData.Columns(x).ItemStyle.Width = widestdata * 25
                        Me.gvSpreadSheetRawData.Columns(x).ItemStyle.Wrap = False
                    End If
            Next
        End If
    End Sub
