Can display the visited path only instead of whole sitemap ?

for example, my site structure as follow:

1. Home
2. Employee
2.1 Employee Details
3. Admin
    3.1 User
        3.1.1 Access Right
    3.2 XXXX

How can i just display the Path "Admin | User | Access Right" when i visit the 3.1.1 Access Right page ?
Thanks

RadGrid custom paging with NeedDataSource issues

I have used custom paging using NeedDataSource but i see a very strange behavior of my RadGrid. I have about 800 records and i am displaying 10 records per page. Also, there is a search mechanism at the top using that user can search records ( i am not using internal filters). Everything works fine. I am taking my search parameters in my radgvRecords_NeedDataSource function and its being passed properly with RowIndexNum and MaximumRows parameters which handles paging.

I see first 10 records on page 1. When i click page 2, i just see 1 record. I checked my stored proc. It is returning 11 records when i pass RowIndexNum =10 and MaximumRows =10. So data is coming perfectly from database but RadGrid only displays the last row from this result set. I see data going through my BAL to my ASPX.CS page. The other strange part is when i hit page 3,4,5,6,7,... i see data properly without any problem. Its just on page 2. I am pasting my bidding code here.

protected void radgvRecords_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

// get search paramters

string fname = txtPatientFName.Text.Trim();

string lname = txtPatientLName.Text.Trim();

string sDate = txtStartDate.Text.Trim();

string eDate = txtEndDate.Text.Trim();

string email = txtEmail.Text.Trim();

int docid = Int32.Parse(ddlDoctors.SelectedValue.ToString());

int clinicId = Int32.Parse(Session["cid"].ToString());

bool status = false;

// balance search parameters

if (sDate.Trim() == null || sDate.Equals(""))

{

sDate = System.Data.SqlTypes.SqlDateTime.MinValue.Value.ToShortDateString();

}

if (eDate.Trim() == null || eDate.Equals(""))

{

eDate = DateTime.Now.ToShortDateString();

}

objFactory fac = new objFactory();

IPrescription objPres = fac.getPrescriptionObject();

VirtualItemCount = objPres.getTotalCountForSearchResult(sDate, eDate, fname, lname, docid, email, clinicId);

radgvRecords.MasterTableView.VirtualItemCount = VirtualItemCount;

radgvRecords.VirtualItemCount = VirtualItemCount ;

int startRowIndex = ((ShouldApplySortFilterOrGroup())? 0 : radgvRecords.CurrentPageIndex * radgvRecords.PageSize);

int maximumRows = ((ShouldApplySortFilterOrGroup())? VirtualItemCount: radgvRecords.PageSize) ;

List<IPrescription> pList = objPres.searchPrescriptionCustomPaging(sDate, eDate, fname, lname, docid, email, clinicId, startRowIndex, maximumRows);

radgvRecords.DataSource = pList;

}

SelectedValue is empty when binding to a generic list

Hi,

I am binding a RadDropDownTree to a Generic List (ListofT) as shown in the example at http://www.telerik.com/help/aspnet-ajax/dropdowntree-databinding-array.html, but the control's SelectedValue property is always empty. Is there a way to get the ID of the selected node from the control? Or is there something different I have to do make the SelectedValue property take on the ID property in the example?

Thanks.

Charles

Hi, i try tu put a loading panel on a masterpage, but return me a error:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">

</telerik:RadAjaxManager>

<telerik:RadAjaxPanel runat="server" ID="loadPanel" HorizontalAlign="NotSet">

<asp:ContentPlaceHolder runat="server" ID="MainContent" />

</telerik:RadAjaxPanel>

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Hi,

With the new version Q2 I found a problem. I had code with Q1 that "creates items" in the entries collection and aftre the user clicks save the collection is read again and differences are saved to the db (via oa).

Now, with Q2 however, the collection is not changed after deleting an entry.

In the example 2 items are added on loading-first-time. When you delete an entry in the box and click the first button (left side) you can see that the count is still 2 and not 1. When you go back to Q1, you will find that the count = 1.

Is this a bug or a feature? ;-)

Automatic Rotation of X-Axis Labels

Hi,
I'm trying to achieve what's already provided in Microsoft Charting control, if the label text is large then it will automatically rotate it. How can I achieve it in Telerik?

I know we can set Rotation Angle of labels but chart shows different labels based on user selection, I don't want to always rotate them. As I don't know which user selection will cause large labels so I can't manually set the rotation angles.

Please see attached images ...if I browse chart on weeks, the labels are automatically rotated

Thanks,
Safeer
