我已将WebHierarchicalDataGrid拖到页面上并告诉它不要自动生成波段或自动生成列。启用Ajax未选中。通过代码隐藏，我手动为父表和子表创建了网格上的列。我双击RowSelectionEvent来测试事件是否会触发。当我从子表中选择一行时，事件永远不会触发。是否有我不知道的子行选择事件？如果没有，有人可以告诉我从所选子行获取字段数据的正确方法。我已经在这方面工作了好几天，我很沮丧，似乎没有简单的方法来完成这项任务。任何帮助是极大的赞赏。
这是我的代码：
protected void WebHierarchicalDataGrid1_Init（object sender，EventArgs e） { string physicianNPI; physicianNPI = Session.Contents [“physicianNPI”]。ToString（）;
// Create Parent Row - Patient Table
WebHierarchicalDataGrid1.DataSource = WebHierarchicalDataSource1;
WebHierarchicalDataGrid1.DataKeyFields = "MPI";
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("MPI", "MPI"));
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("Fname", "Fname"));
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("Lname", "Lname"));
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("DOB", "DOB"));
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("Address", "Address"));
WebHierarchicalDataGrid1.Columns.Add(CreateNewBoundDataField("SSN", "SSN"));
// Create Child Rows - Referral Table
WebHierarchicalDataGrid1.Bands.Add(CreateNewBand("LinqDataSource1Referrals_DefaultView", "LinqDataSource1Referrals_DefaultView", "REFGUID"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("MPI", "MPI"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("RefDate", "Refferal Date"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("RefReason", "Referral Reason"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("Insurance", "Insurance"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("AcceptDate", "Accept Date"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1Referrals_DefaultView"].Columns.Add(CreateNewBoundDataField("DenyDate", "Deny Date"));
// Create Child Rows - UpLoad Table
WebHierarchicalDataGrid1.Bands.Add(CreateNewBand("LinqDataSource1UpLoad_DefaultView", "LinqDataSource1UpLoad_DefaultView", "UploadIndex"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1UpLoad_DefaultView"].Columns.Add(CreateNewBoundDataField("MPI", "MPI"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1UpLoad_DefaultView"].Columns.Add(CreateNewBoundDataField("FileDate", "File Date"));
WebHierarchicalDataGrid1.Bands["LinqDataSource1UpLoad_DefaultView"].Columns.Add(CreateNewBoundDataField("FileType", "File Type"));
this.WebHierarchicalDataGrid1.Columns[0].Hidden = true;
WebHierarchicalDataGrid1.Bands[0].Columns[0].Hidden = true;
WebHierarchicalDataGrid1.Bands[1].Columns[0].Hidden = true;
}
public static BoundDataField CreateNewBoundDataField(string columnName, string headerText)
{
BoundDataField boundDataField = new BoundDataField();
boundDataField.DataFieldName = columnName;
boundDataField.Key = columnName;
boundDataField.Header.Text = headerText;
return boundDataField;
}
public static Band CreateNewBand(string key, string dataMember, string dataKeyField)
{
Band band = new Band();
band.AutoGenerateColumns = false;
band.Key = key;
band.DataMember = dataMember;
band.DataKeyFields = dataKeyField;
return band;
}
protected void WebHierarchicalDataGrid1_InitializeBand(object sender, BandEventArgs e)
{
foreach (var item in e.Band.Columns)
{
if (item is BoundDataField)
{
BoundDataField field = item as BoundDataField;
string fieldname;
fieldname = field.ToString();
// Set the column width for each field displayed in a grid.
if (fieldname.Contains("Fname"))
{
field.Width = Unit.Parse("75");
}
if (fieldname.Contains("Lname"))
{
field.Width = Unit.Parse("75");
}
if (fieldname.Contains("Address"))
{
field.Width = Unit.Parse("190");
}
if (fieldname.Contains("DOB"))
{
field.Width = Unit.Parse("75");
}
if (fieldname.Contains("SSN"))
{
field.Width = Unit.Parse("75");
}
if (fieldname.Contains("FileDate"))
{
field.Width = Unit.Parse("75");
}
if (fieldname.Contains("FileType"))
{
field.Width = Unit.Parse("100");
}
}
}
取得一些进展。当我选择第二个子行时，行选择事件现在正在触发。我在WebHierarchicalDataGrid上更改了以下属性。
WebHierarchicalDataGrid1属性 - ＆gt;选择 - ＆gt; AutoPostBackFlags - ＆gt; RowSelectionChanged - ＆gt;真（原本是假的）
我也做了这些改变。不确定他们是否有所作为。
属性 - ＆gt; RowSelectorClientEvents - ＆gt; RowSelectorClicked - ＆gt; WebHierarchicalDataGrid1_Selection_RowSelectionChanged
属性 - ＆gt; RowSelectorClientEvents-＆GT; RowSelectorClicking - ＆gt; WebHierarchicalDataGrid1_Selection_RowSelectionChanged
这是GRID ASP.net代码：

尝试将您的行为部分更改为
<Behaviors>
<ig:Selection RowSelectType="Single" CellClickAction="Row" CellSelectType="None">
<AutoPostBackFlags RowSelectionChanged="True" />
</ig:Selection>
</Behaviors>
只需确保在任何点击行选择被触发
