Hi all,

I have RadNumericTextBox with 10 DecimalDigits. I would like to hide any trailing zeros. If value is 0.1456000000, I want to display 0.1456.

Any ideas?

How do I control this area of the grid?

Referring to forum append: http://www.telerik.com/community/forums/aspnet-ajax/grid/gridhtmleditorcolumn---how-to-control-size-in-edit-form.aspx
I'm still learning the grid. I see how the size of the actual editing control (either the GridHtmlEditorColumn itself or a custom) can be controled.

What I'd like to know is if there's a way to control the area of the surface on which the editor itself opens.

What I mean is, if for example I set the editor height to 600 pixels given the technique outlined above, the editor overflows the bounds of the entire grid. Under some conditions it could obscure other controls.

Anyway to control this?

RadComboBox inside RadListBox - how to add items

I have followed the examples found elsewhere in the forums for adding a radcombobox to a listbox. Now that I have that working, how do I add the items to the control?
In the item template I have the following:

<ItemTemplate>

<span> <%# DataBinder.Eval(Container, "Text")%>

<telerik:RadComboBox ID="radTimeClockIDs" runat="server" CausesValidation="False">

<Items>

<telerik:RadComboBoxItem Text="1" Value="1"/>

<telerik:RadComboBoxItem Text="2" Value="2"/>

</Items>

</telerik:RadComboBox>

</span>

</ItemTemplate>

In the codebehind, I am adding items to the radlistbox, but they do not appear. I suspect that is because of the item template.

Now that I have the template in place, how do I add list items programmatically? Also, preliminarily I simply placed some items in the RadComboBox that is displayed. However, I will need to be able to put different items in the combobox based on the item that is placed as the list item.

My specific scenario requires a list of items that can be checked so the information can be supplied to a database function, however, each of the items that will populate the list will have a secondary value that is part of a configuration setting. The possible configuration values should appear in the RadComboBox, but each combobox may hold different values.
Essentially it will be three columns in the listbox. One with a checkbox, one with a text value and one with a combobox that is filled based on the text value in the listitem.

Is that possible with this control? If not, is there a better solution?

Thanks!

Hierarchical Business Object bind problem

Dear Supporter,

I've just started using Telerik, I could achieve a few things very nicely, but now I've run into a strange problem.
I'm trying to bind a grid to a hierarchical structure of business objects. I've set up the NeedDataSource event handler and even the DetailTableDataBind, and with the HierarchyDefaultExpanded = true parameter the hierarchy displays in the grid just as I need, the problem comes when the detail tables get collapsed and expanded again.

The code behind for a simple RadGrid (with 'RadGrid1' name):

public partial class Default : System.Web.UI.Page

{

public class Customer

{

public int id { get; set; }

public string name { get; set; }

public string city { get; set; }

public List<Contact> Contacts { get; set; }

}

public class Contact

{

public int id { get; set; }

public string name { get; set; }

public string email { get; set; }

}

public static List<Customer> Customers = new List<Customer> {

new Customer() { id = 1, name = "Bridget", city = "New York", Contacts = new List<Contact>() {

new Contact() { id = 1, name = "John", email = "johnny@hotmail.com" },

new Contact() { id = 2, name = "Mark", email = "mark@hotmail.com" }

}

},

new Customer() { id = 2, name = "Carol", city = "London", Contacts = new List<Contact>() {

new Contact() { id = 1, name = "Henry", email = "henry@hotmail.com" },

new Contact() { id = 2, name = "Hugo", email = "hugo@hotmail.com" },

}

};

void RadGrid1_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

e.DetailTableView.DataSource = ((Customer)dataItem.DataItem).Contacts;

}

void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

if (!e.IsFromDetailTable)

RadGrid1.DataSource = Customers;

}

protected void Page_Init(object sender, EventArgs e)

{

RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

RadGrid1.DetailTableDataBind += RadGrid1_DetailTableDataBind;

}

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;

RadGrid1.MasterTableView.AutoGenerateColumns = true;

RadGrid1.MasterTableView.DataKeyNames = new string[] { "id" };

GridTableView contactsTable = new GridTableView(RadGrid1);

contactsTable.AutoGenerateColumns = true;

RadGrid1.MasterTableView.DetailTables.Add(contactsTable);

}

When I collapse a detail table (by clicking on the expand/collapse button at the left side of the master row) and when I try to expand that again, the DetailsTableDataBind event handler throws an exception, because it doesn't receive the real business object (of the master row) which would contain the needed Contacts child list (the dataItem.DataItem in RadGrid1_DetailTableDataBind event handler is null after the collapse+expand action, but at first render it contains the needed Customer object as needed).

I have no more idea about the issue and I searched over the forum and googled a lot, but I always find solutions which binds to dataset or sqldatasources, but in our case custom classes is the only option.
I don't think I'm doing everything badly because the grid in full expanded mode displays correctly, only after collapse+expand the child table disappears (actually I think the master row's datasource is lost somewhere).

The pasted sample is a simplified version of our current situation, but it reflects my problem.
Btw. I was using RadControls for ASP.NET AJAX Q2 2012 SP2, Bin40 assemblies, 2012.2.912.40 versions.

Any help would be appreciated.

Regards,
Dexx

Grid shows new items on refresh, but not TreeView

Hello,
I'm using FileExplorer with a custom DB content provider, and everything works beautifully with one small exception: When I add directory items and do a refresh, the new child directories do not appear in the treeview, although they are correctly returned and displayed in the grid. I have tried all manner of suggestions found in the forums here, but with no satisfaction. The only thing that gets the new directories to display is a full refresh of the page containing the FileExplorer. I am using version 2010.1.519.20 of the controls. Any assistance would be appreciated.

Changing Status during RadAjaxLoadingPanel in process

I have following code.

1. What I want to achieve is, to keep updating label2 as program statements proceeds eg. "Loading,.... ", "Connecting....."
"Applying Changes......" "Done..". The Idea is to keep user inform about the current status , when processing takes longer time.

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Telerik" >

<asp:Label ID="Label2" runat="server" ForeColor="Red">Loading... </asp:Label>

<asp:Image ID="Image1" runat="server" Width="224px" Height="48px" ImageUrl="~/Loading.gif">

</asp:Image>

</telerik:RadAjaxLoadingPanel

Following is my code behind.

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

Label2.Text = "Connecting to Source";

......... Long code to retrieve data from DB into UC datasource.

RadGrid1.DataSource = uc;

Label2.Text = "Apply Results.";

}

But this does not seem to work...... Is there a better workarond ?

radStyleSheetManager error

I've got a radEditor in a form template of a radGrid editor. I had a problem with the size of the radEditor when it displays the first time, so on the advice of another forum post I added the following to my master page.

<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server">

<StyleSheets>

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Editor.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Window.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI.Skins" Name="Telerik.Web.UI.Skins.WebBlue.Window.WebBlue.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

This worked fine on my desktop at work, but on my laptap I get the following error:

Work computer is currently on Q2 2012 version and laptop is on Q3 2013. The only other difference I can find is that at work the referenced dlls are in my projects /Bin folder, and at home they are referenced from the GAC. Is there a problem with the StyleSheetManager finding dlls that are in the GAC?
