Hello Kristian,

I have know what cause the trigger InitializePostBack event,It is because in client side ,I have an event

function WebGrid1_OnRowSelect(gridId, tblName, rowIndex, rowElm) {

            var grid = ISGetObject("WebGrid1");

            var key = rowElm.keyValue;

            {

                grid.AddInput("key", key);

                grid.SendCustomRequest();

            }

            return true;

        }

and grid.SendCustomRequest() cause to trigger the InitializePostBack event.

 I want that when just mouse click one row ,it trigger InitializePostBack ,this has been realized.But when I selected the checkbox,it also trigger InitializePostBack ,I wonder when choosing checkbox,it should not trigger  InitializePostBack ,can this be realized? please see my attachment.Thank you!

Hello,

It is not possible when you use SendCustomRequest(). This method will do flypostback request to the server. Besides, to click checkbox will automatically call OnRowSelect event. This is a default behaviour.
