ASPXGridView ClientSideEvents如何获取所选行的KeyField值

Question

我正在尝试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, 'MyKeyFieldName', OnGetRowValues); }">
//This gives the same result with Method #2

问题是:如何在没有回调或回发的情况下在客户端RowClick事件中收集当前所选行的KeyField Value(而不是之前但是)？

Answer 1

方法#2和#3

这两种方法都需要回调服务器.

确保已指定行选择操作所需的ASPxGridView.KeyFieldName属性.

如何在没有回调或回发的情况下收集所选行@客户端的KeyField值？

处理客户端ASPxClientGridView.SelectionChanged事件;

确定刚通过" e.isSelected "属性选择的行;

通过客户端ASPxClientGridView.GetRowKey方法确定行的keyValue .

将" e.visibleIndex "属性作为参数传递:

<ClientSideEvents SelectionChanged="function(s, e) {
    if (e.isSelected) {
        var key = s.GetRowKey(e.visibleIndex);
        alert('Last Key = ' + key);
    }
}" />
