I am creating a webpart that has a radlistview on it. It uses a webservice (actually a generic handler because I cant figure out how to make a webservice actually return proper json and not xml) to get its data. That works perfectly. I have now added a raddatapager into my layouttemplate and I know that it is sort of working because if i change the pagesize member in the raddatapager, it does change the amount of records that come back. The only problem: none of the buttons are showing up in my datapager.

Here is a snippet of code:

Main code to build the RadListView

private void BuildResultPanel()

{

_mppUserListView = new Telerik.Web.UI.RadListView()

{

ID = "MPPUserResultList",

RegisterWithScriptManager = true,

AllowPaging = true

};

var mainDiv = new HtmlGenericControl("Div");

mainDiv.Attributes.Add("style", "overflow:hidden;border:1px solid black;padding:5px;margin-top:15px");

this.Controls.Add(mainDiv);

mainDiv.Controls.Add(_mppUserListView);

_mppUserListView.LayoutTemplate = new PhotoUploadLayoutTemplate();

var photoUploadResultItemTemplate = new PhotoUploadResultItemTemplate();

var container = new Control();

photoUploadResultItemTemplate.InstantiateIn(container);

var s = RenderControl(container);

//_mppUserListView.ItemTemplate = photoUploadResultItemTemplate;

//_mppUserListView.ItemPlaceholderID = "items";

_mppUserListView.ClientSettings.DataBinding.ItemTemplate = s;

_mppUserListView.ClientSettings.DataBinding.ItemPlaceHolderID = "items";

_mppUserListView.ClientSettings.DataBinding.DataService.Location = "/_layouts/services/MPPusersPhotoBioUpload/MPPUsers.ashx";

_mppUserListView.ClientSettings.DataBinding.DataService.DataPath = "GetMPPUsers";

if (MIAjax != null) MIAjax.AjaxSettings.AddAjaxSetting(_mppUserListView, _mppUserListView, MIAjaxLoader);

}

PhotoUploadLayoutTemplate:

public void InstantiateIn(Control container)

{

var dataPager = new RadDataPager { PagedControlID = "MPPUserResultList",

ID = "MPPUserResultList_pagerTop", PageSize = 20 };

dataPager.Fields.Add(new RadDataPagerButtonField() { FieldType = PagerButtonFieldType.FirstPrev });

dataPager.Fields.Add(new RadDataPagerButtonField() { FieldType = PagerButtonFieldType.Numeric, PageButtonCount = 5 });

dataPager.Fields.Add(new RadDataPagerButtonField() { FieldType = PagerButtonFieldType.NextLast });

container.Controls.Add(dataPager);

...

}

The raddatapager does render and shows a nice rectangle.. BUT NO BUTTONS!! :(

Please let me know what I am doing wrong. I have the ajaxmanager on the page, the radscriptmanager. And it would appear I have it right since the ajax call is being made and the result list is showing the first 10 or 20 records (depending on my pagesize). I just want to know why the buttons are not showing up. And its not a CSS thing because I can see in the HTML that they arent rendering at all.

Thanks
Loren
