I am using SSRS in VS 2010 (not sure if this was the correct forum). I am getting the following error:
Warning 1 [rsAggregateOfInvalidExpressionDataType] The Value expression for the textrun ‘Textbox118.Paragraphs[0].TextRuns[0]’ uses an aggregate function with an expression that returned a data type not valid for the aggregate function. M:\Reports\AgDirt\Project file backup\Test Purchase.rdl 0 0
I had a textbox118, that just had a database values in it (=First(Fields!EyeColor.Value, "SellerInfo")). Since I had copied and pasted the textbox. I thought it might have been corrupted somehow. So I deleted the textbox and created one from scratch. I still get the error.
I opened the RDL file and looked for that textbox. It does not exist in the RDL file.
Any ideas. Thanks in advance.
