I bought a version of Radcombo version 2.3.2.0 when it was sold separately. It was for a project that ran in asp.net (in vb) Developed with VS 2005.
I am now trying to upgrade the project to VS 2010 and run with framework 4.0, but Radcombo gives an error on the web page. I imagine this is because I am using the 2.0 DLL.
What do I need to do to get this working.
If I cant get a framework 4.0 version do I need to upgrade and how much does this cost. I am only using this one control.
Many thanks for your help.

Export button exporting data that appeared before postback.

Hello Telerik support team,
Of the lifetime of my application the RadChart's datasource is periodically updated on postback. This works when viewing the radgrid on the webpage, but when clicking the export button the first set of data is exported instead of the new data based on postback.

Any suggestions?

Two-way databinding in ListView

Is there a way to persist changes in a textbox within a listview to the correct object in a custom object list?
I cannot find an elegant way to do this.

ASPX:

<telerik:RadWindow ID="rwCreateTask" runat="server" Modal="True" Height="600px" Width="400px">

<ContentTemplate>

<telerik:RadListView ID="RadListView1" runat="server">

<ItemTemplate>

<table>

<tr>

<td>

</td>

<td>

Oppgave:

</td>

<td>

Type:

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Line") == DBNull.Value ? "" : Eval("Line") %>'></asp:Label>

</td>

<td>

<telerik:RadTextBox ID="RadTextBox1" runat="server" Text='<%# Bind("Text") == DBNull.Value ? "" : Bind("Text") %>' OnTextChanged="RadTextBox1_TextChanged"></telerik:RadTextBox>

</td>

<td>

<telerik:RadDropDownList ID="RadDropDownList1" runat="server" DataSourceID="taskTypeSource" DataTextField="Name" DataValueField="TaskTypeId">

</telerik:RadDropDownList>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:RadListView>

<telerik:RadButton ID="RadButton1" runat="server" Text="Legg til oppgave" OnClick="RadButton1_Click"></telerik:RadButton>

</ContentTemplate>

</telerik:RadWindow>

Code-behind:

public partial class TaskListControl : System.Web.UI.UserControl

{

BindingList<CogTaskGenItem> taskItems = new BindingList<CogTaskGenItem>();

CogTaskGenItem taskItem = new CogTaskGenItem();

protected void Page_Load(object sender, EventArgs e)

{

if (Session["taskItems"] != null)

{

taskItems = (BindingList<CogTaskGenItem>)Session["taskItems"];

}

protected void btnCreateTask_Click(object sender, EventArgs e)

{

string script = "<script>openWindow();</script>";

Page.ClientScript.RegisterStartupScript(Page.GetType(), "OpenTaskWindow", script);

}

public void RadButton1_Click(object sender, EventArgs e)

{

AddTaskItem();

}

private void AddTaskItem()

{

taskItem = new CogTaskGenItem();

taskItem.Line = taskItems.Count + 1;

taskItems.Add(taskItem);

RadListView1.DataSource = taskItems;

Session["taskItems"] = taskItems;

}

protected void RadTextBox1_TextChanged(object sender, EventArgs e)

{

taskItems.Clear();

foreach (var item in RadListView1.Items)

{

taskItem = (CogTaskGenItem)item.DataItem;

taskItem.Text = ((RadTextBox)sender).Text;

taskItems.Add(taskItem);

}

RadListView1.DataSource = taskItems;

Session["taskItems"] = taskItems;

}

ComboBox with dynamically added items strange behavior

Hi!

I'm populating RadComboBox (CheckBoxes = true) with items in Javascript:

combo.trackChanges();

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text(subType.Text);

comboItem.set_value(subType.Id);

combo.get_items().add(comboItem);

combo.commitChanges();

But when I'm selecting those items, they're not appearing in the combobox as selected (see attached screenshot).
If I'm adding items on the server, everything works well.
How do I add those items to get everything working as it should?

Thank you

RadRotator in DNN module

I have a news module I am modifying by adding a "slideshow" for news articles. I'm using the radrotator for the slideshow and have it set up on a regular asp.net but want to in cooperate it into the DNN site. Everything works fine when I am NOT logged in, but when I login it is just blank. Has anyone come across this before? If so how can I fix it?

Performance Issues when displaying 15 minute appointments

Hi

I have a RadScheduler which is displaying appointments of 15 minutes each, over a period between 11am - 9pm in week view. (364 appointments)

It takes about 9 seconds to load each time I navigate to a different week but only 1 second when viewing in day view.

I'm running on localhost so I don't think it's the database query and I'm returning only the visible appointments in the query:

var sessions = db.CableSessions.Where(o => o.StartTime > start && o.StartTime < schedulerInfo.ViewEnd).OrderBy(o => o.StartTime);

I am using Webservices to populate the radscheduler.

Is it normal for it to take this long to display 364 appointments? Maybe I'm being too ambitious. Is there anything else I could be doing to speed up the display of the appointments?

Thanks

[edit]:
I have since noticed that this performance issue only occurs when I run the application using CTRL+F5. When I open the page in a different browser, or close the browser and open it again to the same page, the performance issue is resolved.

RadAsyncUpload

Hi,

We have used a RadAsyncUpload in our application(dotnet 3.5 framework). The control works fine locally. When the application is hosted on IIS7, the files are selected but the status is shown unsuccessfull with red color besides.
On the click of Upload button files are not been uploaded and the textbox clears on post back.

Would you tell me what are the changes to be made in web.config file of application to use the control in server??

Regards,
Sid
