This is my last hope please help me I am stuck with that check box in pdf editor. I'm using iText library to generate pdf file based on template. But when I try to set checkbox field it won't filled. My code is below

form.SetField("topmostSubform[0].Page1[0].c1_01_0_[0]","1");
form.SetField("topmostSubform[0].Page1[0].c1_03_0_[0]", "true");
form.SetField("topmostSubform[0].Page1[0].c1_02_0_[0]", "2");
form.SetField("topmostSubform[0].Page1[0].c1_04_0_[0]", "On");

I have tried with following values

1) "Yes"
2) "1"
3) "true"
4) "On"
5) "2"

some one suggest me pass this value. I tried but this one also not working in my code.

The way you are setting the value is fine, but the value you are going to set should be matched with the Export Value

Q: how to find export value

Ans: If you can open the pdf in the Acrobat or any other pdf designer/editor You can find its value by right click property ... Export Value

If Export Value is Y just set the value like

form.SetField("topmostSubform[0].Page1[0].c1_01_0_[0]","Y");

You already use 'Yes' for checkbox. I also filled pdf using ItextShap.

As per my knowledge, If you pass 'Yes' then it will check, you pass nothing then It will uncheck. Do one thing, Please share file with me.I will check in my code, after I will tell, what is the problem exactly.

Thanks .
