Question

I set up a gridview to display search results on a webpage.

I have the code below that is “supposed” to replace any instance of a search term, with a bolded version of that word.

I’ve tried many different versions, but nothing is working.

    Private Sub gvSearchResults_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvSearchResults.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        For Each cell As TableCell In e.Row.Cells
            If cell.Text.Contains(searchTerm) Then
                cell.Text = cell.Text.Replace(Session("SearchTerm"), "<span style='font-weight: bold;'>" & Session("SearchTerm") & "</span>")
            End If
        Next
    End If
End Sub

Is there anything missing in my logic?

Thanks!

If the Cell.Text is blank, then likely the gridview is placing a Literal control in the Cell.Controls collection. You should put something like this in:

If e.Row.RowType = DataControlRowType.DataRow Then
    For Each cell As TableCell In e.Row.Cells
        If cell.Controls.Count > 0 Then
            Dim ltl as Literal = CType(cell.Controls(0), Literal)
            If ltl.Text.Contains(searchTerm) Then
                cell.Text = cell.Text.Replace(Session("SearchTerm"), "<span style='font-weight: bold;'>" & Session("SearchTerm") & "</span>")
            End If
        End If
    Next
End If
