You can customize the existing toolbar, however it is not possible to extend it.
You can hide the default reportviewer toolbar using the code
ReportViewer1.ShowToolBar = falseCustomize your Toolbar
You can write your own Find Button as:
Dim found As Integer = Me.ReportViewer1.Find(txtFind.Text, 1)
If found > 0 Then
btnFindNext.Enabled = True
Else
MessageBox.Show("String not found", "Info", MessageBoxButtons.OK, MessageBoxIcon.Information)
btnFindNext.Enabled = False
End If
Return True
Your own export to pdf button:
refer my earlier article "render rdlc as pdf"
Your own export to excel button:
Follow the steps as mentioned in my earlier article "render rdlc as pdf"
and replace the code in Samples.aspx with the one given below :
Protected Sub Page_SaveStateComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.SaveStateComplete
Dim warnings As Warning() = Nothing
Dim streamids As String() = Nothing
Dim mimeType As String = Nothing
Dim encoding As String = Nothing
Dim extension As String = Nothing
Dim bytes As Byte()
Dim FolderLocation As String = "D:\SampleProjects\"
'First delete existing file
Dim filepath As String = FolderLocation & "Employee.xls"
File.Delete(filepath)
'Then create new excel file
bytes = ReportViewer1.LocalReport.Render("Excel", Nothing, mimeType, encoding, extension, streamids, warnings)
Dim fs As New FileStream(FolderLocation & "Employee.xls", FileMode.Create)
fs.Write(bytes, 0, bytes.Length)
fs.Close()
'Set the appropriate ContentType.
Response.ContentType = "application/vnd.ms-excel"
'Write the file directly to the HTTP output stream.
Response.WriteFile(filepath)
Response.End()
End Sub
End Class
To customize the reportviewer Messages
You can implement the IReportViewerMessages interface to provide custom localization of the ReportViewer control user interface. This implementation can be passed to the ReportViewer control by adding a custom application setting to the the web.config file using the key “ReportViewerMessages”.
For example:
<appsettings>
<add value="MyClass, MyAssembly" key="ReportViewerMessages">
</appsettings>
The following code is an example of a class that implements the IReportViewerMessages interface.
Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.Reporting.WebForms
Namespace MySample
Public Class MyReportViewerCustomMessages
Implements Microsoft.Reporting.WebForms.IReportViewerMessages
#Region "IReportViewerMessages Members"
Public ReadOnly Property BackButtonToolTip() As String
Get
Return ("Add your custom text here.")
End Get
End Property
Public ReadOnly Property ChangeCredentialsText() As String
Get
Return ("Add your custom text here.")
End Get
End Property
Public ReadOnly Property ChangeCredentialsToolTip() As String
Get
Return ("Add your custom text here.")
End Get
End Property
Public ReadOnly Property CurrentPageTextBoxToolTip() As String
Get
Return ("Add your custom text here.")
End Get
End Property
#End Region
End Class
End Namespace
Note: All messages are not implemented here. If you do not specify custom messages then the default is taken.
