Textbox validating menu click
For this I write simple VB code and place it in the custom code window.
Function Description Here you see I have written a function Check Date that accepts a Start Date and End Date parameter and checks the validation against these dates and returns a Boolean value true and false.
Now we can access the Is Valid Date parameter in the SSRS report where we need to call the Check Date function.
If you want to learn about SSRS report creation then go to this link: Here we see only validation using custom code. Apply validation on the from date and the to date parameter of SSRS.(The From date should be less than the To date.)For this we need to go SSRS report (RDL file) where we need to implement the same validation.I've been trying to find a plugin, but haven't really found anything that does this...EDIT: There are some other good answers here that will prevent the input from taking place.
