Radgrid button click to expand child grid

I need to click the "+" sign to open a Child grid, but my user doesn't want the "+" sign on the very left of the grid, they want at the middle of the grid in a column before the file status, when click the "+" sign to open another grid to see a list of files.

Then I think i need to put an image which has the "+" sign the the colum, when click the "+" sign, open the child grid to see the list of files. How to click the button to open a the child grid? How there are any other ways to do this? Do you have an example for it?

Thanks

RadGrid - Self-referencing Hierarchy

I have setup an application according to this demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx

Now i am facing a problem.
I dont know how to fetch the DataKey from my mastertableview (parent item).

My Grid looks like:
-Parent A
-Child A
-Child B
-Parent B

In the nestedtableview under Parent A (holding Child A and Child B) i hit the new button thats in the command item template, and want to insert Child C. Now i dont know how to get the DataKeyValue from Parent A, so that i can set the correct relation in my code behind insert method.

Hope you guys can help me.

Update:
Some pseudo code for further explanation:

protected void paGrid_Insert(object source, GridCommandEventArgs e)

{

string parentID = e.Item.ParentItem.DataKeyValues["PARENT_ID"];

//SQL Insert Statement with the parentID to set Relation ...

}

RadGrid with dynamic data

Hi Guys,

I'm using a RadGrid to show the results of a phone book on my company's website. I can load the information just fine, however the paging is just not right. I give the users the ability to search for a name and/or they can choose from a dropdown for the department or location. Initially the page loads just fine and if there is more than 20 results for their query the paging shows as it should. When I go to the next page in the paging, I get an empty grid.

The grid is connected to an SqlDataSource (as with the 2 dropdowns) and on the submit button, I dynamically change the SqlDataSource to whatever the user wants to search on.

Any help will be greatly appreciated!

William

Advanced Form with Object Data Source

I am trying to adapt the AdvancedForm Scheduler example to leverage the ObjectDataSource. However, it appears I am having problems with the parameter names on insert.

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" DeleteMethod="DeleteAppointment"

InsertMethod="InsertAppointment" SelectMethod="AllData" TypeName="Tradewind.Core.AppointmentList"

UpdateMethod="UpdateAppointment">

<DeleteParameters>

<asp:Parameter Name="ID" Type="String" />

</DeleteParameters>

<UpdateParameters> 

<asp:Parameter Name="ID" Type="String" />

<asp:Parameter Name="Subject" Type="String" />

<asp:Parameter Name="Start" Type="DateTime" />

<asp:Parameter Name="End" Type="DateTime" />

<asp:Parameter Name="RecurrenceRule" Type="String" />

<asp:Parameter Name="RecurrenceParentID" Type="Object" />

<asp:Parameter Name="RecurrenceState" Type="Object" />

</UpdateParameters>

<InsertParameters>

<asp:Parameter Name="Subject" Type="String" />

<asp:Parameter Name="Start" Type="DateTime" />

<asp:Parameter Name="End" Type="DateTime" />

<asp:Parameter Name="Description" Type="String" />

<asp:Parameter Name="Reminder" Type="Object" />

<asp:Parameter Name="UserID" Type="Object" />

<asp:Parameter Name="RoomID" Type="Object" />

<asp:Parameter Name="RecurrenceRule" Type="String" />

<asp:Parameter Name="RecurrenceParentID" Type="Object" />

<asp:Parameter Name="RecurrenceRuleText" Type="String" />

<asp:Parameter Name="RecurrenceState" Type="Object" />

</InsertParameters>

</asp:ObjectDataSource>

<div class="exampleContainer">

<telerik:RadScheduler runat="server" ID="RadScheduler1" Width="750px"

DataEndField="End" DataKeyField="ID"

DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentID"

DataSourceID="ObjectDataSource1"

DataStartField="Start"

DataSubjectField="Subject"

SelectedDate="2007-03-30" TimeZoneOffset="03:00:00"

OnDataBound="RadScheduler1_DataBound" AppointmentStyleMode="Default"

OnAppointmentCreated="RadScheduler1_AppointmentCreated"

OnAppointmentDataBound="RadScheduler1_AppointmentDataBound"

OnClientFormCreated="schedulerFormCreated"

EnableDescriptionField="true">

<AdvancedForm Modal="true" />

<Reminders Enabled="true" />

<AppointmentTemplate>

<div class="rsAptSubject">

<%# Eval("Subject") %>

</div>

<%# Eval("Description") %>

</AppointmentTemplate>

<AdvancedEditTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedEditForm1" Mode="Edit"

Subject='<%# Bind("Subject") %>'

Description='<%# Bind("Description") %>'

Start='<%# Bind("Start") %>'

End='<%# Bind("End") %>'

RecurrenceRuleText='<%# Bind("RecurrenceRule") %>'

Reminder='<%# Bind("Reminder") %>'

UserID='<%# Bind("User") %>'

RoomID='<%# Bind("Room") %>' />

</AdvancedEditTemplate>

<AdvancedInsertTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedInsertForm1" Mode="Insert"

Subject='<%# Bind("Subject") %>'

Start='<%# Bind("Start") %>'

End='<%# Bind("End") %>'

Description='<%# Bind("Description") %>'

RecurrenceRuleText='<%# Bind("RecurrenceRule") %>'

Reminder='<%# Bind("Reminder") %>'

UserID='<%# Bind("User") %>'

RoomID='<%# Bind("Room") %>' />

</AdvancedInsertTemplate>

<TimelineView UserSelectable="false" />

<TimeSlotContextMenuSettings EnableDefault="true" />

<AppointmentContextMenuSettings EnableDefault="true" />

</telerik:RadScheduler>

My Object which this is bound to "Tradewind.Core.AppointmentList" looks like the following.

public static void InsertAppointment(

string Subject, DateTime Start, DateTime End, string Description,

Object UserID, Object RoomID, string RecurrenceRule, Object RecurrenceParentID, string RecurrenceRuleText, Telerik.Web.UI.RecurrenceState RecurrenceState)

{

List<AppointmentInfo> sessApts = AllData();

AppointmentInfo ai = new AppointmentInfo(Subject, Start, End);

ai.RecurrenceRule = RecurrenceRule;

ai.RecurrenceParentID = RecurrenceParentID;

ai.RecurrenceState = RecurrenceState;

sessApts.Add(ai);

}

This worked fine for the basic example, but gets more complex with the AdvancedForm and new resources. I know this has something to do with my ObjectDataSource not having the correct parameters as I get the following error.

bjectDataSource 'ObjectDataSource1' could not find a non-generic method 'InsertAppointment' that has parameters: Subject, Start, End, Description, Reminder, UserID, RoomID, RecurrenceRule, RecurrenceParentID, RecurrenceRuleText, RecurrenceState, .

Any help on where I can find a collection or something of the proper parameters, or a better suggestion on how to do this would be welcome.

Many thanks.

Paging to Selected Row

I have a multi-page radgrid that allows the user to select a singe record. I persist that selection in a session variable while they go do other things on other pages.

Is there a way for me to load the grid (when they return) and have it load the grid-page that contains their selected row? I assume I can cause it to be selected during a server-side event but am not sure how I can control which page the grid shows or be sure that it is going to contain the saved selected item.

Advice?

Thanks.

Mike
