当另一个更改客户端时，Telerik RadGrid设置单元格值

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了当另一个更改客户端时，Telerik RadGrid设置单元格值相关的知识，希望对你有一定的参考价值。
我有一个RadGrid，其中某些列处于批量编辑模式。我还有两列依赖于另一个值（EstLengthFt和EstLengthRds）。我需要在编辑EstLengthFt单元格时更新EstLengthRds值，反之亦然。我只更新html而不是值的当前函数。我需要更新控件的值并将其设置为BatchEditChanged模式，以便我可以保存它。
我不能做任何回发，因为编辑的值会丢失。
任何帮助将不胜感激！
function AllSetCellValue(sender, args) {
var grid;
var master;
var selected;
var row;
var ft;
var cell;
var rods;
if (args.get_columnUniqueName() == "EstLengthFt") {
grid = $find('<%=RadGridAll.ClientID%>');
master = grid.get_masterTableView();
selected = master.get_selectedItems();
row = selected[0];
ft = args.get_value();
cell = master.getCellByColumnUniqueName(row, "EstLengthRds");
rods = Math.round((ft * .060606060606) * 100) / 100;
cell.innerHTML = rods;
}
if (args.get_columnUniqueName() == "EstLengthRds") {
grid = $find('<%=RadGridAll.ClientID%>');
master = grid.get_masterTableView();
selected = master.get_selectedItems();
row = selected[0];
rods = args.get_value();
cell = master.getCellByColumnUniqueName(row, "EstLengthFt");
ft = Math.round((rods * 16.5) * 100) / 100;
cell.innerHTML = ft;
}

答案
看一下BatchEditingManager提供的客户端API，看看你是否可以把它放在一起：http://www.telerik.com/help/aspnet-ajax/grid-batch-editing.html。本文的第三部分处理客户端API。

我能够通过在我的comboBox模板列中使用OnValueChanging事件来解决这个问题。我还添加了两个隐藏的列来存储原始值，以便我可以进行比较并确定哪个单元格已更改。唯一的问题是当值更改时，comboBox再次触发OnValueChanging事件并创建一个连续循环。我在更改值后为comboBox添加了一个.Set标志以防止这种情况发生。以下代码解决了我的问题。
function AllConvertValue(sender, args) {
var grid = $find('<%=RadGridAll.ClientID%>');
var master = grid.get_masterTableView();
var getRow = master.get_selectedItems()[0];
var row = master.get_dataItems()[getRow._itemIndex];
var cellFt = row.findControl("txtEstLengthFt");
var cellRds = row.findControl("txtEstLengthRds");
var oldFt = row.findControl("OldFtValue");
var oldRds = row.findControl("OldRdsValue");
if (cellFt != null && cellRds != null) {
if (oldFt._value != cellFt._value) {
var rods = (cellFt._value * 0.060606061).toFixed(2);
if (cellRds.Set != true) {
cellRds.Set = true;
cellRds.set_value(rods);
}
if (oldRds.Set != true) {
oldRds.Set = true;
oldRds.set_value(cellRds._value);
}
if (cellFt.Set != true) {
cellFt.Set = true;
cellFt.set_value(cellFt._value);
}
if (oldFt.Set != true) {
oldFt.Set = true;
oldFt.set_value(cellFt._value);
}
}
if (oldRds._value != cellRds._value) {
var ft = (cellRds._value * 16.500033).toFixed(2);
if (cellFt.Set != true) {
cellFt.Set = true;
cellFt.set_value(ft);
}
if (oldFt.Set != true) {
oldFt.Set = true;
oldFt.set_value(cellFt._value);
}
if (cellRds.Set != true) {
cellRds.Set = true
cellRds.set_value(cellRds._value);
}
if (oldRds.Set != true) {
oldRds.Set = true;
oldRds.set_value(cellRds._value);
}
}
if (oldFt._value == cellFt._value && oldRds._value == cellRds._value) {
cellFt.Set = false;
cellRds.Set = false;
oldFt.Set = false;
oldRds.Set = false;
}
}
}
