OnClientDoubleClicking property missing?

Hi guys,

Am I doing something silly here, looking at the documentation for the RadTreeView (http://www.telerik.com/help/aspnet-ajax/tree_overviermigrating.html) I see there should be a method OnClientDoubleClicking that would allow me to hook into the handling of a double-click and cancel under certain conditions.

However, I only see OnClientDoubleClick which occurs too late for what I need to do.

Frustratingly I can see OnClientNodeClicked and OnClientNodeClicking so what's going on? And yes I've tried a dummy method using the same signature and it doesn't fire.

Any ideas?

thanks

GridLines in RadGrid

Hello All,

I have a RadGrid, I have applied skin webBlue to it, now what I want is the border for the items in the grid, I want the Gridlines on the grid. The only solution what I am getting is to apply border to all fields but I don't want to do this.

OnInsert Event

** SORRY POSTED ON WRONG FORUM ** (--->MVC)
Is there a way to catch the new row event - like OnEdit() ?
I wish to do some manipulation on the new inserted row (in edit mode).
But I don't want this manipulation to occur in existing rows in Edit Mode (hence the OnEdit Event doesn't help).

To be more specific - I have a dropdownlist , while in inset mode I want to pass values from the selected item to other columns.
but I don't want it to be enabled on regular edit mode at all....

How can I achieve this ?

RadGrid problems with data

Hi,

I'm having some problems with records disappearing from grid.
I'm attaching screenshots to show the problem.

This is the behavior of the problem:

Web page is loaded and all records are retrieve (164 records) paged every 10 records (very fast, 3 sec).
Moving to another page of records all works fine but very slow (22 sec).
If I try to filter the grid from the filter field, for a record in the list, the record is not found (confirmed, the record exists).
If I clear the filter (setting button to None) it takes a lot of time to get all record again and only 131 records are showed.
I've confirmed that the bind function always return 164 records and not 131 as grid show.

This is the code for aspx page:

Code Behind for binding:

// Bind main grid

{

ListGrid.DataSource = BindControls();

}

protected IEnumerable<Customer> BindControls()

{

var customers = customersRepository.GetAllCustomers();

return customers;

}

// Bind contacts grid

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

{

(sender as RadGrid).DataSource = BindContactsControls();

}

protected IEnumerable<Contact> BindContactsControls()

{

var contacts = contactsRepository.GetContactsByCustomer(System.Convert.ToInt32(CurrentRecordId));

return contacts;

}

// Bind addresses grid

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

}

protected IEnumerable<Address> BindAddressesControls()

{

var addresses = addressesRepository.GetAddressesByCustomer(System.Convert.ToInt32(CurrentRecordId));

return addresses;

#endregion

And this is the code for Customers repository:

using System.Linq;

using System.Transactions;

using System.Data;

namespace Quasar.Repository

{

public class CustomersRepository

{

// Create data context

private QuasarEntities entities = new QuasarEntities();

// Retrieve all Customers

public IQueryable<Customer> GetAllCustomers()

{

return entities.Customers.OrderBy(o => o.Name);

}

// Retrieve a Customer by Id

public Customer GetCustomer(int id)

{

return entities.Customers.FirstOrDefault(d => d.CustomerId == id);

}

// Add Customer

public int Add(Customer customer)

{

using (TransactionScope transaction = new TransactionScope())

{

try

{

entities.Customers.AddObject(customer);

entities.SaveChanges();

// Commit Transaction

transaction.Complete();

return customer.CustomerId;

}

catch

{

return 0;

}

// Delete Customer

public bool Delete(Customer customer)

{

using (TransactionScope transaction = new TransactionScope())

{

try

{

// Delete Customer and childs

entities.Customers.DeleteObject(customer);

entities.SaveChanges();

// Commit Transaction

transaction.Complete();

return true;

}

catch

{

return false;

}

// Persistence

public bool Save()

{

using (TransactionScope transaction = new TransactionScope())

{

try

{

entities.SaveChanges();

// Commit Transaction

transaction.Complete();

return true;

}

catch

return false;

}

Please, any help?

animation

I'm using q3 2010 controls. I am using the Fade animation on a modal window. The first time I do a window.show(), it flashes the form quickly, and then it does my animation. Any subsequent window.show() animates without this initial flashing.

exportToExcel client side not functioning with column renderers

Greetings folks,
I'm using the client side exportToExcel function like so: gridView().exportToCsv().
The csv that gets generated doesn't contain all of the expected data I see on the grid.
The problem is I'm using column renderers on these fields to interpret numerical values and display them as text in english.
For some reason the exportToCsv only includes the underlying numerical data.

Is there anyway around this?
Or do I just have to bind the text data to the grid...

thanks

Setting Checked Nodes

I'm trying to set checkboxes as checked on a radtreeview with tristatecheckboxes set to true. Using the code below works when there is only one level, but having trouble where there are 3 levels (passing in a comma delimted string of checkbox values).

protected void selectCheckedNodes(RadTreeView treeView, string val)
        {
            if (!string.IsNullOrEmpty(val))
            {
                string[] cbarray = new string[] { "" };
                cbarray = val.Split(',');

                foreach (string i in cbarray)
                {

                    RadTreeNode obj = treeView.Nodes.FindNodeByValue(i);
                    if (obj != null)
                        obj.Checked = true;
                }
            }
        }

Can someone show me how to iterate thru the treeview to check the approriate nodes? I am not passing in the parent categories, just the specific nodes I want checked. Thanks!

RadAjaxManager fails radscheduler advanced edit form

Hi,

I'm trying to fix this error for days now.

I have got a radscheduler control in my web form and of course RadAjaxManager with radAjaxLoadingPanel.

Since i have replaced my Q1 radcontrols with Q2, my nightmare began.
With Q1 controls, when I clicked twice on an appointment, the advanced edit form was shown immediately after Ajax was loaded. With Q2 controls, when I click on an appointment twice, the advanced edit form should appear. It appears, but there is no form...only the buttons to save and to cancel editing are shown. ???

If I disable RadAjaxManager, everything works normal.

Does someone have a clue what is going on?

I am about to conclude my project, and I really don't know what to do with this any more.

Please help.

LP, Luka
