RegisterClientScriptBlock的问题 [英] Issue with RegisterClientScriptBlock

问题描述

我对RegisterClientScriptBlock有问题.
场景是，我在javascript中声明了数组，并在后面的代码中将值传递给它.有一个带有checkbox的gridview，其checkstate更改了，我在获取数据，然后再次将其分配给javascript中的数组.

 DataTable tblDeliveries = 空;
        tblDeliveries = 此 ._ bingmapData.SelectDriversDelivery(driverId);

        StringBuilder脚本= 新 StringBuilder();

         int  i =  0 ;
         foreach (数据行 in 中的tblDeliveries.Rows)
        {
            script.AppendFormat(" ，即第[ 拉特"，]，行[" ]，行[" ])；
            i ++;
        }
ScriptManager.RegisterClientScriptBlock( this ， this  .GetType()， " ，script.ToString()， true ); 

这是复选框checkstate change event中的代码.工作正常，但是当我应用updatepanel时，我没有得到想要的结果.在页面Source上，它们是较旧的条目，而不是我从事件传递的新条目.

我花了4个小时在此，最后发现一个很小的东西导致了这个问题.我必须重新初始化数组.
script.AppendFormat("_ locations = new Array();");
真的很小的事情很重要.

Hi,
I have a issue with RegisterClientScriptBlock.
Scenario is,I have array declare in javascript and from code behind I am passing values to it.There is a gridview with checkbox with their checkstate changed I am fetching data and then again assign it to array in javascript.

DataTable tblDeliveries = null;
        tblDeliveries = this._bingmapData.SelectDriversDelivery(driverId);

        StringBuilder script = new StringBuilder();

        int i = 0;
        foreach (DataRow row in tblDeliveries.Rows)
        {
            script.AppendFormat("_locations[{0}]= new VELatLong({1}, {2});_driverColor[{0}]='{3}';", i, row["Lat"], row["Long"], row["DriverColor"]);            
            i++;
        }
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "PointArrays", script.ToString(), true);

This is the code in checkbox checkstate change event.Working fine but when I apply updatepanel i am not getting desired result.On page Source their are older entries not the new that I passed from event.

解决方案

I have spend 4 hours in this and at the end I find a very small thing that causing the problem.I have to reinitialize the array.
script.AppendFormat("_locations=new Array();");
Really small things matters.
