Hi all ,
I have got problem when i am tring to exportGridview Data into Excel
format.
It is going into text format ,but what i want is if the field is
number/currency then it should go into number/currency format
itself .Data exported to excel are all exported as text.
Export to excel should maintain the formatting like numbers and money
should be numbers and money in excel .
Here is the code provided, please someone correct my code.currently i
am getting correct ouput but thing is i want exported data into
particular format.
Protected Sub btnExportToExcel_Click(ByVal sender As Object, ByVal e
As EventArgs)
Dim fromDate As String
Dim toDate As String
fromDate = txtFromEffectiveDate.Text.ToString()
toDate = txtToEffectiveDate.Text.ToString()
If PanelGVEffectiveDate.Visible = True Then
ExportToExcelFromTo(SqlDataSource1, "", fromDate, toDate)
ElseIf PanelGVDateAdded.Visible = True Then
ExportToExcelFromTo(SqlDataSource3, "", fromDate, toDate)
Else
ExportToExcel(SqlDataSource5, "")
End If
End Sub
