Masked textbox combined with numeric textbox spinner

Does anyone know if it's possible to combine the RadMaskedTextbox with the spinner control that's on the RadNumericTextbox? I'm trying to replace a JQuery UI time picker, that implements a masked input and a spinner, with a Telerik alternative.

I've got the easy bit done...

<telerik:RadMaskedTextBox runat="server" ID="RadMaskedTextBox1" Mask="<0..23>:<0..59

>">

</

telerik:RadMaskedTextBox>

and as far as I can see there isn't an option to enable the spinner, but if anyone can suggest a solution I would be eternally grateful!

Is there a way to bind the cursor key up/down event to a button click?

Parent vertical orientation + child horizontal orientation

Hi,

I'm currently working with tabs. I saw on a forum post that it is impossible to change child orientation of tabs.
I made my own system of childs:

First, I have a ratabstrip wich is the main with 5 tabs( on the left)
This Radtabstrip have a multipage view. Inside it, i have 5 pages wich contain a radtabstrip. (on the top)
Each of this radtabstrip have a multipage view with 3,5,7 and 9 tabs.
See the attached picture "tabs" to see what i am talking about.

It's working fine when I select a left tab. My top tab change, and when I click on it, it display the appropriate content.
But when i select another tab, there is still the content of the other pages.
See the attached pictures "content".

2 questions :
Is it possible to make this more simple ?
How can I hide a multipage when I click on the left tabs ?

Many thanks for your help !

Selected and focus nodes not the same

Hi I've got a problem with the ASP.NET Rad Treeview, with checkboxes. The user is able to navigate about the treeview using the cursor keys. However it seems the actual focus is not changing, it appears the focus is changing as the class of rtSelected class is being applied corresponding to the user's navigation using the cursor keys. The actual focus can be changed using the tab key. I've got screen shots which clearly show the focus and the highlighted (selected) nodes being different in IE and Chrome

Chrome...

http://i49.tinypic.com/sf9og0.png

The selected field text is highlighted in grey. The input with focus is highlighted with a yellow box.

IE

http://i49.tinypic.com/adhhls.png

The selected field text is highlighted in grey. The input with focus is highlighted with a dashed outline.

This is not just a cosmetic issue I'm finding when the user selects a node using the space bar, OnNodeCheck is fired twice, once for the selected node and another time for the node with focus.

The focus and the selected node should be the same regardless of what input method is used.

I have GridEditCommandColumn with an image in it that I want to be invisible until I mouseover anywhere in its row.

I've been messing with cssclass and with the OnRowMouseOver client event but I've not been able to work it out.

Does anyone have the magic incantation I can use...

Thanks, Steve

Rebind certain child RadListView in client side

I have a hierarchical RadListView:

<telerik:RadListView ID="RadListView1" runat="server" DataSourceID="SqlDataSource0"...>

......

<ItemTemplate

> 

<%
 
# Session["CatalogID"] = Eval("SerialsID").ToString()%>

<telerik:RadListView ID="RadListView2" runat="server" DataSourceID="SqlDataSource1"...>

.....

<ItemTemplate

> 

<%# Session["ProductID"] = Eval("ProductID").ToString()%>
 
 
<asp:Button runat="server" ID="btnRebind_Production" Text="" OnClientClick="somefunction"/>

<telerik:RadListView ID="RadListView3" runat="server" DataSourceID="SqlDataSource2"

...> 

....

<ItemTemplate>

<div>

<asp:Button runat="server" ID="btnRebind_Detail" Text="" OnClientClick="somefunction()/>

 

 

 
 
 
<asp:ImageButton runat="server" ID="img1" AlternateText="" CausesValidation="false" ImageUrl='<%# Eval("ImageURL") %>' Width="180px" Height="180px" />

<div>

</ItemTemplate>

</telerik:RadListView>

</ItemTemplate>

</telerik:RadListView>

</ItemTemplate>

</telerik:RadListView>

When I click btnRebind_Detail, I only want to rebind RadListView 3. The problem was that when I call

$find(

"<%= RadListView1.ClientID %>").rebind(), the data sets for RadListView2 and 3 are wrong. I tried to wrap the RadListView3 with UpdatePanel and call _doPostBack("UpdatePanel1", ' '), but the dataset for RadListView 3 is wrong, it populated the ListView3 with another Catalog's details. Is there a way to only rebind certain child RadListView in Client-Side?

Client Side Validation with Nested UserControl and Ajax Manager

How do I get a Nested User Control to use client-side validation?

Here's the validator:

<telerik:RadTextBox ID="txtAuditor" runat="server">

</telerik:RadTextBox>

<asp:RequiredFieldValidator runat="server" ID="rfvAuditor" ControlToValidate="txtAuditor"

ErrorMessage="Auditor is required" Display="Dynamic" ForeColor="Red" ValidationGroup="Audit">*</asp:RequiredFieldValidator>

My user control has "btnUpdate" is inside the User Control:

<telerik:RadButton ID="btnUpdate" Text="Update" runat="server" CommandName="Update" ValidationGroup="Audit">

The user control includes the Validator in the RadAjaxManagerProxy:

<telerik:RadAjaxManagerProxy runat="server" ID="RadAjaxManagerProxy">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnUpdate">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="btnUpdate" />

<telerik:AjaxUpdatedControl ControlID="rfvAuditor" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy

>





The Grid in the parent control uses the User Control:


<EditFormSettings UserControlName="~/Controls/ComplianceFormAuditControl.ascx" EditFormType="WebUserControl">
                                                       <EditColumn UniqueName="EditCommandColumn1">
                                                       </EditColumn>
                                                   </EditFormSettings>



The Audit validation summary is available on the page:


<asp:ValidationSummary runat="server" ID="vsAudit" ForeColor="Red" ValidationGroup="Audit" />





The Rad Ajax Manager on the parent page is configured:


<telerik:AjaxSetting AjaxControlID="grdAudit">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="grdAudit" />
                <telerik:AjaxUpdatedControl ControlID="vsAudit" />
            </UpdatedControls>
        </telerik:AjaxSetting>





Doesn't seem to work. I have tried to manually call validation without success:


protected void grdAudit_InsertCommand(object sender, GridCommandEventArgs e)
        {
            Page.Validate("Audit");
            InsertUpdateAudits(e, ComplianceFormAuditEntity.Status.New);
        }





Any ideas?

What is the Right approach for CRUD operation using grid.

Hi,

For example sake: Lets take Orders table or Customers table or any table.

What i believe is in most of the cases, the grid is not used to display data from Orders table directly. Its always a view table eg. vOrders
Where vOrders connects to various other tables and data is displayed in grid. this means that any feature of automatic insert/update will not be of useful, also a grid might just display few columns that are needed , but while editing or inserting it needs all columns that are present in Orders table and not of vOrders. which means during edit/insert I need to query main orders table (single row by querying a particular OrderID)

Is there a live example to demonstrate this.

The only way I could see is using "Custom Control.ascx", but the related examples are a bit confusing , because it just passes current reocord to customcontrol as "dataitem" and then after insert/update the main aspx page queries control for individual values and proceeds with action. so there is very much tight dependency on aspx and ascx. (makeing it difficult to reuse .ascx elsewhere)

I wish to learn what approach other developers have taken or recommend me. It would be nice if telerik team gives some good suggestion/knowledge .

Regards

Sorting and Grouping at client side

Hi,
I would like to implement sorting and grouping at client side, no post backs. So, intention is to get all the data in one go and then let user group/sort at client side. Please let me know if I can use RadGrid's client side events for this.

Thanks,
SV
