我正在使用以下代码。 在.aspx中：
function AccessOnclient() {
debugger;
var grid = $find("<%= dg_InvPat.ClientID %>");
if (grid) {
var MasterTable = grid.get_masterTableView();
var sumtemp = 0;
var Rows = MasterTable.get_dataItems();
for (var i = 0; i < Rows.length; i++) {
var row = Rows[i];
var RadNumericTextBox1 = row.findControl("txt_projInv");
if (RadNumericTextBox1.get_value())
{
sumtemp =sumtemp + RadNumericTextBox1.get_value();
}
}
for (var i = 0; i < Rows.length; i++) {
var row = Rows[i];
var RadNumericTextBox1 = row.findControl("txt_projInv");
var valinv=RadNumericTextBox1.get_value();
var res=Math.round((valinv/sumtemp)*100);
var revpat = MasterTable.get_dataItems()[i].findElement("lbl_revpat");//access the Label control
revpat.innerText = res;
}
document.getElementById("ctl00_MainContent_b1").click();
}
}

这里当我在radgrid中的templatecolumn中修改文本框时，相应的值存储在标签（Radgrid的GridTemplateColumn）中。那是用javascript编写的。但是没有显示相应的融合图。当我调试时，不考虑新值（由javascript计算）。只有在网格中绑定的值才会在融合图中绘制。
在DrawGraph（）函数中，我使用名为修改模式（GridTemplateColumn）值的标签作为<set label值。但新的价值不会到来。
例如。如果我在项目投资列中给出600，相应的百分比42将进入修订模式（GridTemplateColumn）。但融合图表没有改变。
如何解决问题？
任何人请帮助我.........
答案 0 :(得分：4)
我建议你去文本框而不是标签
因为文本框是服务器控件而标签有问题总是获取值 就像你使用更新面板一样...... 因此，文本框将是使用
的最佳选择
