Expanding groups propagates to detail tables with GroupLoadMode="Client"

Hello,

I am having a problem when I use GroupLoadMode="Client" and HierarchyLoadMode="Client" with a RadGrid. The problem is that when I expand a group, all of the group's row's detail tables expand as well.

Is there a setting to stop this or any way to work around this? Fetching the data in our real life application is costly so the client modes are the only acceptable ones for the scenario.

The markup looks like below and is being fed data from a dataset, also shown below.

<telerik:RadGrid ID="RadGrid1" runat="server">

<MasterTableView DataMember="Employee" DataKeyNames="ID" GroupLoadMode="Client" HierarchyLoadMode="Client" GroupsDefaultExpanded="false">

<GroupByExpressions>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="Location" />

</GroupByFields>

<SelectFields>

<telerik:GridGroupByField FieldName="Location" />

</SelectFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<DetailTables>

<telerik:GridTableView DataMember="EmployeeProperties" DataKeyNames="ID">

<ParentTableRelation>

<telerik:GridRelationFields MasterKeyField="ID" DetailKeyField="EmployeeID" />

</ParentTableRelation>

</telerik:GridTableView>

</DetailTables>

</MasterTableView>

</telerik:RadGrid>

protected override void OnInit(EventArgs e)

{

RadGrid1.NeedDataSource += new Telerik.Web.UI.GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);

RadGrid1.DetailTableDataBind += new Telerik.Web.UI.GridDetailTableDataBindEventHandler(RadGrid1_DetailTableDataBind);

base.OnInit(e);

}

void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

DataSet ds = GetDataSource();

e.DetailTableView.DataSource = ds;

}

void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

DataSet ds = GetDataSource();

RadGrid1.DataSource = ds;

}

private DataSet GetDataSource()

{

DataSet ds = new DataSet();

DataTable employee = ds.Tables.Add("Employee");

DataTable employeeProperties = ds.Tables.Add("EmployeeProperties");

var empKey = employee.Columns.Add("ID", typeof(int));

employee.Columns.Add("FullName", typeof(string));

employee.Columns.Add("DepartmentID", typeof(string));

employee.Columns.Add("Location", typeof(string));

var empPKey = employeeProperties.Columns.Add("ID", typeof(int));

var empPFK = employeeProperties.Columns.Add("EmployeeID", typeof(int));

employeeProperties.Columns.Add("Title", typeof(string));

employeeProperties.Columns.Add("Value", typeof(string));

employee.PrimaryKey = new[] { empKey };

employeeProperties.PrimaryKey = new[] { empPKey };

ds.Relations.Add(new DataRelation("rel", empKey, empPFK));

employee.Rows.Add(new object[] { 1, "Scott Smith", 1, "Sweden" });

employee.Rows.Add(new object[] { 2, "Adam West", 1, "Sweden" });

employee.Rows.Add(new object[] { 3, "John Doe", 2, "Norway" });

employee.Rows.Add(new object[] { 4, "Sven Svensson", 2, "Norway" });

employee.Rows.Add(new object[] { 5, "Anders Andersson", 3, "Finland" });

employee.Rows.Add(new object[] { 6, "Jane Doe", 3, "Finland" });

employee.Rows.Add(new object[] { 7, "Stan Smith", 4, "United States of America" });

int i = 0;

foreach (DataRow emp in employee.Rows)

{

string[] s = ((string)emp["FullName"]).Split(new[] { ' ' });

employeeProperties.Rows.Add(new object[] { ++i, (int)emp["ID"], "GivenName", s[0] });

employeeProperties.Rows.Add(new object[] { ++i, (int)emp["ID"], "GivenName", s[1] });

}

return ds;

}

RadGrid get reference to RadDatePicker control within EditFormTemplate on Clientside

Hello,

Can you tell me how to find reference to a RadDatePicker control that resides in the EditFormSettings of a RadGrid on client side javascript for validation purposes. I have spent quite some time browsing the forums and other online help but can't find the answer.

I need this on the OnClientClick event of a button control, I have tried attaching the event from the code behind but it is not behaving correctly. So i want to get the reference to the control on client side itself.

Please Help!!!

Thanks,
Kavitha

Self-Referencing Hierarchy using LINQ and Nullable Guids

Following the help from http://www.telerik.com/help/aspnet-ajax/grdselfreferencinghierarchy.html, I cannot seem to find a FilterExpression that works with my data source. I am using the NeedDataSource event to set the data source like this:

dcConnections dc = new dcConnections();

g.DataSource = dc.GetMetrics();

dcConnections is my DataContext, GetMetrics is a stored procedure that returns a list of Metrics. The Metrics have an ID and ParentID, both of which are Guids. ParentID can be null. So, from the example, I tried to set the FilterExpression like this:

if (Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("3.5") != -1 || Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("4.0") != 1)

{

g.MasterTableView.FilterExpression = @"it[""ParentID""] == null";

}

else

{

g.MasterTableView.FilterExpression = "ParentID IS NULL";

}

This errors out with "No applicable indexer exists in type 'Metric'", which makes sense, since I need to use the it.ParentID format to get to the column in the Metric normally, so I change it to this:

g.MasterTableView.FilterExpression = @"it.ParentID == null";

That errors with "Operator '==' incompatible with operand types 'Guid?' and 'Object'".

So now, I can't figure out how to compare the values of a Guid? in a FilterExpression. Normally, using == null would work for Nullable Guids. Any suggestions?
