Add Group Header: Please check mark this option, If you want to add a header to this group.Group By: Here, you have to specify the grouping column name.How do you use a row group in SSRS report? In Group expression, leave the expression blank.In the Grouping pane, right-click a group that is an innermost child group.On the design surface, click anywhere in a tablix data region to select it.

Now, lets see how to use this new defined function in our SSRS report.To add a details group to a tablix data region

Give your votes to this in order to have SSRS to support this.īasically this code defines a function GenerateThumbnail that given an url ImageUrl and a couple of parameters, fetches the image then resize it to the newWidth and newHeight (preserving the aspect ratio, if needed) and finally returns it as an array of bytes - something SSRS can understand. NOTE: unfortunatelly the SSRS custom code does not support the Imports statement and because of this we can't "beautify" the code. MemoryStream.Read(bytes, 0, CInt(bytes.Length)) bitmapData = memoryStream.ToArray() Try Dim req As = (ImageUrl) Dim response As = req.GetResponse() Dim img As = (response.GetResponseStream()) Dim imgresize As = Nothing Dim bitmapData As Byte() = Nothing If resize Then Dim newWidth2 As Integer Dim newHeight2 As Integer If preserveAspectRatio Then Dim originalWidth As Integer = img.Width Dim originalHeight As Integer = img.Height Dim percentWidth As Single = CSng(newWidth) / CSng(originalWidth) Dim percentHeight As Single = CSng(newHeight) / CSng(originalHeight) Dim percent As Single = If(percentHeight < percentWidth, percentHeight, percentWidth) newWidth2 = CInt(originalWidth * percent)lin newHeight2 = CInt(originalHeight * percent) Else newWidth2 = newWidth newHeight2 = newHeight End If imgresize = New (img, newWidth2, newHeight2) Else imgresize = img End If Using memoryStream As New System.IO.MemoryStream() imgresize.Save(memoryStream, .Png)ĭim bytes As () = New ( memoryStream.Length - 1) In this case I added a function like below: Function GenerateThumbnail(ImageUrl as String, Optional ByVal resize as Boolean = False, Optional ByVal newWidth as Integer = 64, Optional ByVal newHeight as Integer = 64, Optional ByVal preserveAspectRatio as Boolean = True) In there you can put any custom code in VB.net that would solve your specific problem. Make sure you're using Visual Studio and not SSRS Report Builder because the latter one does not permits you to type in your custom code. So here I'll walk you through the solution 2 as I think it can be handy also for others. The most elegant, and low maintenance, solution is the second one. Solution 2: write custom code in SSRS report that would resize the image on the fly. Make the sales order attribute point to the new low resolution image url. Solution 1: set up a script that from time to time would get all the images, make a copy, resize them all and save. One could say that instead of sending the report through the email we better enable those users to SSRS portal and to the cube. This is because the images are high resolution.
When it comes to export the report into an excel file then we run into some problems - the report is actually too big (200MB and more) to be sent through the email. The users can actually run the report and the images are rendered correctly along with the sales orders figures. The datasource is a multidimensional cube and the image is rendered thanks to an image url (pointing to an image on an intranet website) attribute on sales order dimension. We have a SSRS report that, due to business requirements, need to have on each row some sales orders figures and an image that somehow represents what is sold in that specific sales order (an image of all the products in that sales order). As you'll see at the end of this brief artice this isn't actually a difficult requirement but it is somehow not so widespread requirement and because of this very few material can be found that helps you with the implementation. Recently, thanks to one of our client I came accross a simple requirement, yet difficut to implement.
