View 1 RepliesAsp.net GridView IF Empty Show Message?
Apr 2, 2012I've got a grid view. I want it to say "you have nothing to show" if there are no details.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If GridView1.Rows.Count = 0 Then
[Code].....
However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.
I've tried a variety of combinations with the below IF statement below but no success.

View 4 RepliesShow Bit Column As A Checkbox Column In Unbound Datagridview
May 14, 2010Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

VS 2005 - Remove Empty Column From Table
Oct 3, 2011I am using TextFieldParser to Read a Tab Delimited Text DataFile. The problem I have is that some times the data file (3rd party provided) contains an extra Tab which therefore creates an extra column. I need to remove this unnecessary column. Some columns will have rows that are empty so I cant just delete the column if it has a blank row, So I think I need to loop through each column and if if every row is blacnk then delete that column.
Here is the code that reads the file, I was going to remove the column from the table called table before I populate the table called dtAll , which is what my program uses
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)
myReader.SetDelimiters(vbTab)
Dim currentRow As String()

View 1 RepliesC# - Retrieve Not Empty Rows In First Column Of Excel Sheet
Feb 4, 2011My requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example:
358218033354974
359473035499561
358218036156129
354022038366247
358218032490035
359473030516492
353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated):
Using connection As New OleDbConnection(sExcelConnectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
[Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to:
Get only first column of every worksheet
All values that are numeric
Skip empty values
Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.
