remove empty rows in Gridview
Is there a way to remove rows from Gridview if the entrie rows are rows are empty? I do not know in advance the name of the columns or how many columns are are going to be.
Just make sure that you check its Data Source before Data Binding.
Because you mention GridView I'm assuming you're talking about an ASP.NET application using WebForms.
Are you binding the GridView to something or filling it programmatically? If you're binding it, why not filter the datasource before doing the bind (which I think is what the previous responder was getting at). There are several ways to approach that, depending on what the datasource is (objects, datatable, etc).

ASKER
The source is Excel. When I bind to Gridview, I get some empty rows. I want to be able to remove the entire row if they are blank.
See if this works:
Protected Sub Gridview1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Gridview1.RowDataBound
If e.Row.RowType = DataControlRowType.EmptyDataRow Then
e.Row.Style.Add("display", "none")
End If
End Sub
If not, you might need to check each cell:
Sub Gridview1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Gridview1.RowDataBound
dim bolEmptyRow as boolean = false
for i as integer = 0 to e.row.cells.count - 1
if e.row.cells.item(i).text.trim = "" then
bolEmptyRow = true
end if
if bolEmptyRow = true then
e.row.style.add("display", "none")
end If
next
End Sub
Oops... you might need to declare bolEptyRow as global then modify the code above:
Partial Class Utilities_SkuLookUp_SkuDetail
Inherits System.Web.UI.Page
dim bolEmptyRow as boolean = False
dim iRow as integer = 0
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' ...
End Sub
Sub Gridview1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Gridview1.RowDataBound
for i as integer = 0 to e.row.cells.count - 1
if e.row.cells.item(i).text.trim = "" then
bolEmptyRow = true
end if
next
iRow = e.row.rowindex
DeleteRow()
End Sub
Sub DeleteRow()
if bolEmptyRow = true then
Gridview1.rows(iRow).style.add("display", "none")
end If
End Sub
