asp.net customdatagrid 或gridview绑定数据的时候经常要用到的 ItemDataBound 事件的方法

前台aspx页面：

JS获取索引号：

//判定值为大于0的整数
function checkDecisionValue(btn) {
if (btn.parentElement != undefined && btn.parentElement.parentElement != undefined) {
var gridRowIdx = btn.parentElement.parentElement.rowIndex - 1; //获取索引值 这里需要打断点，设置debugger调试才知道索引号
var gridIdx = btn.parentElement.parentElement.rowIndex;
var reDecisionValue = document.getElementById("grdLevelDeterminationResult_reNewDecisionValue_" + gridRowIdx);
if (!IsUnitFormat(reDecisionValue.value) || reDecisionValue.value < 0) {
alert(Resource("BeginWith") + gridIdx + Resource("Row") + Resource("factoryservicedetail_correct_newdecisionvalue"));
reDecisionValue.focus();
reDecisionValue.value = "";
return false;
}
}
}
