Hello Sir

i have a form having 4 rows inside repeater and first column is checkbox on checbox click i want enter value in order no. column textbox. Suppose any checkbox i click the value should be 1 again if i click any check box then value should be 2 again i click any checkbox the vale should be 3 like that 4 also. but if i uncheck any checkbox then value will decrease which is greater that checked value.

Like if i uncheck checkbox of value 3 then checkbox of vale 4 will become 3 in repaeter and so on. https://ibb.co/jgzBgL
