我试图在客户端获取选定的网格行KeyField值;
我曾经尝试过以下各种结果：
方法#1
<ClientSideEvents RowClick="function(s,e) {var key= grid.GetSelectedKeysOnPage()[0];}" />
//This gives prevIoUs selected rows value everytime
方法#2
<ClientSideEvents RowClick="function(s,e) { grid.GetRowValues(grid.GetFocusedRowIndex(),'MyKeyFieldName',OnGetRowValues); }" />
//This gives prevIoUs selected row and also gives an error: "A primary key field specified via the KeyFieldName property is not found in the underlying data source. Make sure.. blabla" But the MyKeyFieldName is true and i dont want to make a callback,i dont want to use this method!
方法#3
<ClientSideEvents RowClick="function(s,e) { grid.GetRowValues(e.visibleIndex,OnGetRowValues); }">
//This gives the same result with Method #2
问题是：如何在客户端RowClick事件中收集(不是以前的但是)当前所选行的KeyField值,而不用回调或回发？
@H_301_18@解决方法
Method #2 and #3
这两种方法都需要对服务器进行回调.
确保您已经指定了行选择操作所需的ASPxGridView.KeyFieldName属性.
How can i gather KeyField Value of selected row @ client without a callback or postback?
处理客户端ASPxClientGridView.SelectionChanged事件;
确定刚刚通过“e.isSelected”属性选择的行;
通过客户端ASPxClientGridView.GetRowKey方法确定行的keyValue.
通过“e.visibleIndex”属性作为参数：
<ClientSideEvents SelectionChanged="function(s,e) {
if (e.isSelected) {
var key = s.GetRowKey(e.visibleIndex);
alert('Last Key = ' + key);
}
}" />
