Compare Validator Control

Rajiya

Hi, I have 2 textboxes one is txtStartTime and the other is txtEndtime. Compare Validator is not Working for these 2 textboxes.I am storing DateTime values in both the textboxes. I want to check if EndTime is Greater then StartTime.If StartTime is Greater then Endtime then It should give an error message saying StartTime cannot be greater then EndTime. Plz suggest me how to do it. thanks, riz

use a compare validator to validate two dates. add one comparevalidator on properties select controltocompare,controltovalidate and value to compare. give value as >, < and change the type property into date this wil fulfil ur requirement, if any error let me know coolsweety

I think you would also want to check that valid dates have been entered. Does this help?
