Two checkboxes respond to each other

229022633

The first and last columns in the grid are checkbox columns;

Assume that the checkbox of the first column is replaced by A, and the checkbox of the last column is replaced by B;


Claim:

1. When B is selected, A is selected automatically;
2. In the state where A and B are selected at the same time, when A's selected state is cancelled, B must also be automatically unselected.

Please prawn, please.

itemCreate:

CheckBox A = e.item.FondControl ("Aid") as CheckBox
CheckBox B = e.item.FondControl ("Bid") as CheckBox

if (A! = null&&B! = null) {
    string js1 = string.Format ("if (document.getElementById ('{0}'). checked) document.getElementById ('{1}'). checked = true;", B.ClientID, A.ClientID);
    B.Attributes ["onclick"] = js1;
   
    string js2 = string.Format ("if (document.getElementById ('{0}'). checked) document.getElementById ('{1}'). checked = false;", A.ClientID, B.ClientID);
    A.Attributes ["onclick"] = js2;
