SSRS Dataset Field Refresh not updating for Tablix

Question 1

Just found it... I don't understand the need for hidden menus like this..

Click the report itself, then go up to View on the menu and at the very bottom there is "Report Data". From here you can select your dataset and go to its properties and refresh the reports attached dataset's fields. What a pain in the butt.

Here is a link that helps better explain it. http://blog.dontpaniclabs.com/post/2012/01/26/Developings-Reports-for-SQL-Server-Reporting-Services

Question 2

You can also delete the .data file if you still can't get it to refresh.

Go into the file folder where the .rdl file exists
Next to it, there should be a file with the same name with the .rdl.data extensions. Delete this file.

It appears to force the refresh probably because it has to recreate the file.

Here's a less invasive way but may not always work:

In the Report Data windown, right click on you dataset and click Dataset Properties like so:

Click Refresh Fields near the bottom right of the Dataset Properties window:

Question 3

After changing the Stored Procedure code, without changing the name and number of fields returned, I could only get the report to seemingly call the new format of the stored procedure by clicking the Refresh button in the report's Preview tab.

Question 4

Go into your solution folder, where the rdl's are stored and delete .rdl.data file for your report. Next time you'll run the report, new rdl.data file will be created and it will have all the new fields from the updated SP.

Question 5

ok, this maybe an older thread, but I kept running into the same problem on occasion. The absolutely easiest way to fix this is adding the following line of code to the beginning of the stored procedure that produces your dataset for the report:

SET FMTONLY OFF;

Happy coding :)

Question 6

I ran into a very similar issue:

Added a new field to an existing SQL table function
(With some difficulty) added the new field to the existing dataset in SSRS
Spent some time unsuccessfully trying to add the new fields to the table (tablix?) in design mode.

This didn't work for me so eventually I opened the particular report file [filename].rdl in a text editor and surprise surprise it was XML. It was easy enough to add the missing field manually, and visual studio then prompted me to refresh the report.

 <DataSets>
  <DataSet Name="DataSet1">
   ...
   <Fields>
    <!-- add new field at this level -->
    <Field Name="[newfield]">
      <DataField>Email</DataField>
      <rd:TypeName>System.String</rd:TypeName>
    </Field>
   </Fields>
  </DataSet>
 </DataSets>

Question 7

I am having exact same issue in VS 2012. The stored procedure used as a query will not allow to refresh fields. When the button is pressed nothing happens.

The only solution I found is to flip the Query Type to Text and provide the parameter values on the exec call to the SP.

Why do we have to put up with these obvious show stopper bugs?

Question 8

Had the same issue and I was able to resolve it by renaming my dataset in properties, creating a new dataset with the original name, and then hitting the refresh button.

Question 9

Old thread, but I ran into this using VS 2015 and SSMS 2016. I was certain it was an issue with VS. When I went back to SSMS and tried executing my stored procedure, however, I found that passing certain parameter values would cause the query to fail. Interestingly, I was able to ALTER the stored procedure without encountering any errors. (Perhaps because some combinations of parameters wouldn't result in a failure?)

Anyways, at the end of the day it was faulty coding in my sproc that was causing the fields in SSRS not to refresh. When I went back and corrected the issues with my code, everything worked as expected in VS.

Question 10

I am working in Visual Studio 2015 and none of the above answers worked for me. If you are getting the data from a stored procedure, you need to open the .xsd file and right click on the data model. Select Configure, and the correct values from the procedure should appear on the right of the window. Then refresh your dataset from the Report Data tab.

Question 11

I had the same issue. I installed SP1 so that .rdl.data file would get generated which inturn also fixed the data refresh issue.

Question 12

I was trying to use an ODBC driver for the datasource that connected ok, but wouldn't show Fields in VS 2015 SSRS report. I went back and used a datasource based on SQL Server driver (it's in the choices when designing a datasource) and it worked perfectly.

Question 13

I had this same issue but the cause was different from the other answers at the time of this writing.

In my case, the stored procedure used as the data source was returning multiple data sets (due to some debugging code that I had left in there).

SSRS was "seeing" the fields in the first dataset, whereas I was expecting it to see the fields in the second dataset.

Removing the extraneous datasets fixed the issue and SSRS was able to see the fields that I intended.

Question 14

Clearing reportviewer's datasources works for me.

this.(reportviewername).LocalReport.DataSources.Clear();

Question 15

Open the Visual Studio 2008 reports solution
Open (double click) your report (.rpt file) on left pane
Press Ctrl + Alt + D to open the Report Data panel
Expand the DataSets folder
Find the report's main data set and right click the "DataSet Properties" menu
Click the "Refresh Fields" button on the popup window.

Question 16

Deleting .data no work for me. Deleting Dataset and adding again worked. And I had previously configured VS/SSRS to NOT cache.

Question 17

refresh and deleting .data did not work for me. So I just manually added the fields.
