Hello Folks, How are you all? I have an issue with Contract Date field, when I write date value through third party project to web-form its working fine as using code below:

IE.Document.Forms.Form1.ctl00_ContentPlaceHolder1_dtContractDate_dateInput_text.Value = txtConDate.Text
But unfortunately Web-form still not see the date value i send to it and error message popps as "Please enter value" while the date value is exist in contract Date field (webform). But for sure will not have this error if entered date directly to ASP form. Please is there any other way to pass date from third party to ASP web-form? appreciated your help inadvance... Thank you
