Posted on by Bharath B J 85

Hi guys,

I'm quite new to SSRS reports. While designing in Visual studio i somtimes get this error.

The error reads "IIF is invalid. InvalidIdentifier". I just want know where this is pointing to. 

I must have done a minor syntax error. I want to know in which tablix/textbox the error is pointing to.

Thanks in advance.

    You have use IIF function wrongly, the valid syntax of IIF is IIF(Your boolean expression, true part, false part). Try to see where you have used IIF function and see if it is valid expression. The error in output screen reflect the textbox name where you have used this function.

    You can open rdl file as xml in notepad and do ctrl+F to find all "iif". (You can find file from VS, there is an option "open file location"). That's the fastest way to find something in SSRS report. I know.
