Accessing an Embedded Resource UserControl from a Embedded R

Posted by Community Admin on 04-Jan-2011 00:00

I have a Usercontrol that inherits from SimpleView that has a RadGrid control in it. The RadGrid uses a UserControl as an edit Form. How can I load the control into the RadGrid EditFormSettings?

I also am trying to use embedded user controls with other controls such as RadWindow. Below is the LocationManager class that manages the Primary page as a user control.

[RequireScriptManager]

public class LocationManager : SimpleView

protected override void InitializeControls(GenericContainer container)

LocationsGrid.NeedDataSource += LocationsGrid_NeedDataSource;

LocationsGrid.InsertCommand += LocationsGrid_InsertCommand;

LocationsGrid.UpdateCommand += LocationsGrid_UpdateCommand;

//LocationsGrid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;

////LocationsGrid.MasterTableView.EditFormSettings.UserControlName = "BranchManagementModule.Resources.EditLocation.ascx";

//LocationsGrid.MasterTableView.EditFormSettings.EditColumn.ButtonType = GridButtonColumnType.LinkButton;

//LocationsGrid.MasterTableView.EditFormSettings.EditColumn.UniqueName = "editColumn1";

//LocationsGrid.MasterTableView.EditFormSettings.EditColumn.InsertText = "Add a new location";

void LocationsGrid_UpdateCommand(object sender, GridCommandEventArgs e)

void LocationsGrid_InsertCommand(object sender, GridCommandEventArgs e)

var item = (GridEditableItem)e.Item;

var userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

var db = new RegionalDataContext();

var location = new BranchLocation

BranchLocationId = Guid.NewGuid(),

BranchLocationName = (userControl.FindControl("txtLocationName") as TextBox).Text,

AddressInfo = (userControl.FindControl("txtAddressInfo") as TextBox).Text

;

if (new Guid((userControl.FindControl("ddlRegionalOffice") as RadComboBox).SelectedValue) == Guid.Empty)

var region = new Region RegionId = Guid.NewGuid(), RegionName = location.BranchLocationName ;

location.RegionId = region.RegionId;

db.Regions.InsertOnSubmit(region);

else

location.RegionId = new Guid((userControl.FindControl("ddlRegionalOffice") as RadComboBox).SelectedValue);

db.BranchLocations.InsertOnSubmit(location);

db.SubmitChanges();

e.Canceled = false;

void LocationsGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

var module = new BranchManagementModule();

LocationsGrid.DataSource = module.GetLocationsAsQueryable();

protected override string LayoutTemplateName

get return "BranchManagementModule.Resources.LocationManagerView.ascx";

protected virtual RadGrid LocationsGrid

get

return Container.GetControl<RadGrid>("RadGrid1", true);

Below is the main page as a user control that is embedded as a resource.

var db = new RegionalDataContext();

var noRegion = new RadComboBoxItem("None - [Creates new Region]", Guid.Empty.ToString());

foreach (Region region in db.Regions.OrderBy(s => s.RegionName))

var regionItem = new RadComboBoxItem(region.RegionName,

Digging Further I have found EmbeddedTemplateAttribute but I am not sure how it works as it doesn't do anything when used as an attribute on the LayoutTemplatePath override

any help??

Hi John Tolar,

First, I want to apologise for the delay.

There is a difference between user controls and custom controls, and you could not have possibly created a user control that inherits from SimpleView, because it doesn't inherit UserControl. It is very important to understand the difference.

The RadGrid documentation states that you cannot load an edit form from an embedded template; it can be loaded as inner template (declaratively) or as user control.

RadWindow can be used as a controls container. It is an iframe, and as such, can open urls and embed them within your page. The effect you are referring to can be achieved if you had a page and pass it as the NavigateUrl of your dialog. The behaviour could be controlled with querystring parameters.
