Hi,
I have been coming across this error very very often.
"A data source instance has not been supplied for the data source"

Please advise why it comes and how to fix it.

I googled it but did not get any solid method to fix it.

Thanks
Furqan

I am facing error A data source instance has not been supplied for the data source

3 solutions

Solution 3

I had the same problem, with 3 datasources in the report while i only used 1.

It looks like i caused this by referencing the same datatable, from multiple datasets.

I removed all extra references to datasources in the form's designer page.

But when i click on the report, to select the datasource all three where still there.

One solution that worked, was to click on the report, and set all datasource instances to the correct dataset-datatable.

But the correct solution that solved the problem, was to edit the report.rdlc file with notepad.

There you will find under "datasets", a section for each datasource.

Carefully delete the sections for the datasets you dont want, problem solved..

Solution 1

I just found the way to fix it.

Got o your ReportViwer that carries the report.
Click on the triangle above and click
Choose Data Sources. Here you will find the binding sources in in your data sets.
Just choose your binding source and you are done.

Donot find triangle can you unfold secret?

Tareq Newaz Shahriar 26-Jan-12 4:20am

lol...here the triangle means the 'smart tag' of the report viewer control. which is actually a '>' sign. and can be found on the designer view of the aspx file.
1. go to your aspx file where the ReportViewer has.
2. click on designer or split view.
3. then on the report viewer control you can see the small smart tag button at top right of that control.
