Object Relational Hierarchy not working

I am attempting to build hierarchy in a grid from business objects. If I select ‘Auto Generate Hierarchy’ and ‘Auto Generate Columns’ it does work. Expanding a parent row shows its related children in RadGrid.

However, when I attempt to programmatically build the relation it does not work. Expanding a parent row does not show its related children.

I have followed the GridView Object Relational Hierarchy Mode documentation word for word without success. I have used ‘property builder’ of the grid as per the tutorial but that did not help either.

Here is a sample code:

private void FormEventStaffPlans_Load(object sender, EventArgs e)

{

// --------- Parent -----------

// Staff plan unique identifier.

GridViewDecimalColumn dColumn = new GridViewDecimalColumn("StaffPlanId");

dColumn.HeaderText = "StaffPlanId";

dColumn.IsVisible = false;

dColumn.ReadOnly = true;

this.radGridViewStaffPlans.Columns.Add(dColumn);

// Total required staff.

dColumn = new GridViewDecimalColumn("NumberOfStaffPerShift");

dColumn.HeaderText = "Staff Req";

this.radGridViewStaffPlans.Columns.Add(dColumn);

// Total male

dColumn = new GridViewDecimalColumn("NumberOfMalePerShift");

dColumn.HeaderText = "Male";

this.radGridViewStaffPlans.Columns.Add(dColumn);

// Total female

dColumn = new GridViewDecimalColumn("NumberOfFemalePerShift");

dColumn.HeaderText = "Female";

this.radGridViewStaffPlans.Columns.Add(dColumn);

// Employee Id (TO DO: change this to dropdown box)

dColumn = new GridViewDecimalColumn("EmployeeId");

dColumn.HeaderText = "Empoloyee";

this.radGridViewStaffPlans.Columns.Add(dColumn);

// Labour hire company Id (TO DO: change this to dropdown list)

dColumn = new GridViewDecimalColumn("HireCompanyId");

dColumn.HeaderText = "HireCompanyId";

this.radGridViewStaffPlans.Columns.Add(dColumn);

this.radGridViewStaffPlans.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

// --------- Child -----------

// Create child template (for staff shifts)

GridViewTemplate childTemplate = new GridViewTemplate();

this.radGridViewStaffPlans.Templates.Add(childTemplate);

// Set columns of child template

// Shift unique identifier.

dColumn = new GridViewDecimalColumn("ShiftId");

dColumn.HeaderText = "ShiftId";

dColumn.IsVisible = false;

dColumn.ReadOnly = true;

childTemplate.Columns.Add(dColumn);

// Shift from (display date only).

GridViewDateTimeColumn dtColumn = new GridViewDateTimeColumn("ShiftFrom");

dtColumn.Format = DateTimePickerFormat.Short;

dtColumn.HeaderText = "Date From";

childTemplate.Columns.Add(dtColumn);

// Shift to (display date only).

dtColumn = new GridViewDateTimeColumn("ShiftTo");

dtColumn.Format = DateTimePickerFormat.Short;

dtColumn.HeaderText = "Date To";

childTemplate.Columns.Add(dtColumn);

// Shift from (display time only).

dtColumn = new GridViewDateTimeColumn("ShiftFrom");

dtColumn.Format = DateTimePickerFormat.Time;

dtColumn.HeaderText = "Shift Start";

childTemplate.Columns.Add(dtColumn);

// Shift to (display time only).

dtColumn = new GridViewDateTimeColumn("ShiftTo");

dtColumn.Format = DateTimePickerFormat.Time;

dtColumn.HeaderText = "Shift End";

childTemplate.Columns.Add(dtColumn);

// Shift part.

dColumn = new GridViewDecimalColumn("ShiftPart");

dColumn.HeaderText = "Shift Part";

childTemplate.Columns.Add(dColumn);

// Break duration.

dColumn = new GridViewDecimalColumn("BreakDuration");

dColumn.HeaderText = "Break Duration";

childTemplate.Columns.Add(dColumn);

// Variation code.

GridViewTextBoxColumn tColumn = new GridViewTextBoxColumn("VariationCode");

tColumn.HeaderText = "Variation Code";

childTemplate.Columns.Add(tColumn);

// Shift cost.

dColumn = new GridViewDecimalColumn("ShiftCost");

dColumn.HeaderText = "Shift Cost";

dColumn.ReadOnly = true;

childTemplate.Columns.Add(dColumn);

// Shift cost type.

tColumn = new GridViewTextBoxColumn("ShiftCostType");

tColumn.HeaderText = "Shift Cost Type";

dColumn.ReadOnly = true;

childTemplate.Columns.Add(tColumn);

// Area (TO DO: change this to dropdown list).

dColumn = new GridViewDecimalColumn("AreaId");

dColumn.HeaderText = "Area";

childTemplate.Columns.Add(dColumn);

// Shift type.

tColumn = new GridViewTextBoxColumn("ShiftType");

tColumn.HeaderText = "Shift Type";

childTemplate.Columns.Add(tColumn);

childTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

// Add the relation between parent (staff plans) and the child (staff plan shifts)

GridViewRelation relation = new GridViewRelation(this.radGridViewStaffPlans.MasterTemplate, childTemplate);

relation.ChildColumnNames.Add("EventShift");

this.radGridViewStaffPlans.Relations.Add(relation);

// Add data source to grid (parent).

IList<EventStaffPlan> list = _siteProxy.GetEventStaffPlans(34);

this.radGridViewStaffPlans.DataSource = list;

}

public class EventStaffPlan:BusinessObject

{

/// <summary>

LoadLayout Not Syncing Groups

Using 2009.3.9.1203 version of RadGridView.
When I load a grid layout with LoadLayout and the grid has grouping, the topmost group does not sync with the grid until the user clicks on the group header. Top + n level subgroups work fine. None of the routines to collapse or expand groups works for the top group. Manually adding and removing the group does not work.

NodeMouseUp not working on checkbox

Forgive me if I am missing something. I was using the NodeMouseUp event to detect when a node was checked or unchecked. The reason I used this and not the NodeCheckedChanged is that NodeMouseUp only fires once whereas NodeCheckedChanged fires for every node checked and when you select the parent node it fires for every child node. The NodeMouseUp worked fine till I upgraded to Q1 2011. Perhaps there is a better way to do what I want. I simply want to know when the selections for the entire tree have been changed and then refresh my GridView based on the values.

Thank You

Quick way to find a record in a bound gridview?

Hi guys,

I'm looking for a quick way to find a record based on one or several values in the grid, datasource for the gridview could be 100 thousand records or more (tied into inventory items for a large grocery store). Telerik gridview is used for a lookup,basically a seed value get's passed to the grid and it needs to locate the record (aka Row) and highlight it.

Could some direct me to right location of an example that would demonstrate the required functionality? Help is appreciated. Thank you.

Event clarification

Thanks in advance for any assistance.

What event would I use to grab the GridRowInfo when the navigates to a another row? I'm working with the RowsChanged event and it's firing after -each- change to the row when evaluating the NotifyCollectionChangedAction.ItemChanged enum.

Essentially, what I need to do, is if any value in the row changes, I need to get the row and update the database. If I use the RowsChanged event, I potentially would be updating the same record over and over if multiple values are changed for the same record.

Do I need to use a combination of events?
1. RowsChanged - store an instance of the GridViewRow to a local variable
then
2. RowValidated - commit row information to database?

Is there a more direct way to do what I need to do?

Thanks,

Morgan

Multiple maximize, minimize and close buttons on a MDI RadRibbonForm

Hello,

Sorry for the long subject line; I wasn't sure how else to phrase it.

First of all, here are my system details: I am using RadControls for WinForms Q1 2009 in C# (I know that it's old, but that's what I'm stuck using for now). I am using Visual Studio 2008 SP1 and this project is using the .NET Framework 3.5. I have some experience with the ASP.NET and Winforms RadControls, but I am by no means an expert.

This project is using a main RadRibbonForm as an MDI parent. It then has several child MDI RadForms which all inherit from a base RadForm. Because I am using a RadRibbonForm, I don't have a menu strip defined. The problem that I'm having is that I have multiple rows of minimize, maximize and close buttons appearing (Please see the screenshots). When I first open up the application, I don't have any of the MDI children visible. However, when I open up one of the MDI children, it opens unmaximized and I can see its title bar. When I maximize the MDI child, I see what is shown in the screenshot ribbonformmdi01.jpg. When I unmaximize or minimize the MDI child, I see what is shown in the screenshot ribbonformmdi02.jpg. Finally, when I close the MDI child, I see what is shown in the screenshot ribbonformmdi03.jpg.

I thought that by setting the the base child MDI RadForm's window state property to "Maximized" in design time, that this would solve the problem. The screenshot ribbonformmdi04.jpg shows what I see when I open the MDI child. It opens maximized, but I have no way of minimizing or closing the child MDI form.

I know that I must be overlooking something. Can anybody offer any help, please? What am I missing? I have been looking all over the forums but the only thing that I've been able to find is what to do if you have a RadMenu and you want to merge the child's RadMenu with the parent's RadMenu. This obviously doesn't apply. I have also tried without any success to set various properties in the child RadForms such as the TitleBar's visibility property but that hasn't done the trick either. Thanks in advance for any help that you can give.

Regards,
John

Various Question about RadGridViews

Hello All,

I have been working with a RadGridView, and I was wondering about a few things.

One, I have a gridview that is populated when an item from a list is selected and a button is checked. When I have BestFitColumns(), the column headers are not present. If I close the table and re-open it, they then appear. Ideas (this might be a bug that was fixed in SP1--I am running the version prior to SP1)?

Second, I have the horizontal scroll bar property set in one of my gridviews, and it never appears. I have tried manually sizing the columns, so that the columns would be bigger than the window and force a scroll bar; however, this isn't working (in fact, in this particular table, it appears that the size of the columns is being controlled by something else). Ideas?

Thanks,

single quotes in radtextbox

Hi,
I have a problem in my application: I have a radtextbox multiline (not ReadOnly) where some text is loaded; this text contains some words within single quotes (').
When I load the whole text of my application in this textbox, the text is correctly visualized, but if I try to modify the text, the control update the content deleting completing the words within quotes and it performs actions not requested.

I think this is due to the texts within quotes.
Is there a way to avoid this behaviour and to manage the text and the words within the quotes as pure text, avoiding the radtextbox text/character events?
I also need to manage text read from an xml document with a xmlnode object and copied to a string: the text contains words within quotes as before.
The text of the xml document is correctly read in the xmlnode object, but the string variable doen' t store the part of text after the first single quotes character and the character itself.
Is a different object more suitable for my purpose? In my application I must use a string variable to store the xml text.

Thanks in advance
