Restrict special characters

Hi,
How to restrict special characters in rad grid?
I have the UI as below:

<telerik:GridTemplateColumn DataField="ProductNumber" HeaderText="Product Number"

UniqueName="ProductNumber" Visible="true">

<InsertItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text="">

</telerik:RadTextBox>

</InsertItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("ProductNumber") %>'>

</telerik:RadTextBox>

</EditItemTemplate>

<ItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("ProductNumber") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

I want to restrict the special characters in InsertItemTemplate and EditItemTemplate.

Thanks

Multiple issues with Export

I am using the Export facilities of the grid straight out of one of your examples and encountering several different problems. The only option that is working correctly is to export to CSV.

(1) When exporting to Excel, my Excel 2010 is opening and the data is loaded from the grid, but after a few seconds, Excel goes into a loop and I have to kill it from Task Manager.

(2) When exporting to a PDF file, the PDF file never displays but I do receive a new window filled with .net errors. (see attached screen capture.

(3) When exporting to CSV, everything works fine and the data is opened in an Excel spreadsheet which operates fine (no problem).

(4) When exporting to Word, Work 2010 starts to open then hangs (never even shows in Task Manager) and I have to click on "Cancel" on the splash screen to get out of Word.

I have included the code (both display and code-behind) below.

The version being used is 2012.3.1016.45; Windows 8 64-bit, VS2012. SQL Server 2008 R2 Standard.

Maintain Selected menu item

HI

Appologies if this has been covered, but I can't find a solution that works to my particular problem.
I have a RadMenu in a user control. This user control is in a place holder on a master page.

What I cant get to work is the menu to maintain the selected menu item when a user clicks on the menu item and the page loads.

I have enabled the EnableSelection property, but I didn't expect it to be that easy.

Radgrid Edit and Insert with different number of columns

I tried to build a grid which has selected 10 columns out of which 3 are readonly.

I should be able to insert by selecting "Add new item" into only 4 columns and when it comes to edit

it should edit 6 columns.

I used this URL to start working
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/templateformupdate/defaultcs.aspx

Grid doesn't compile if I use less fields in insert than edit in SQL Datasource.

There is a also a problem to hide and print grid. One another problem about displaying grid rows in Red if there is a negative value in row.
Please help me and suggest some examples with the above requirement.

multi-field search in mluticolumn - Combo

Hi,

I'd like to use a multicolumn Combo for search reasons.
Here's my current configuration (based on this demo) :

ASPX:

<telerik:RadComboBox ID="rb_fvCustomer" runat="server"

DataSourceID="Customers" EnableAutomaticLoadOnDemand="true" ItemsPerRequest="10"

DataTextField="name" DataValueField="kundennummer"

EnableVirtualScrolling="true" ShowMoreResultsBox="true" Width="190px" HighlightTemplatedItems="true">

<HeaderTemplate>

<table style="font-size: 10px">

<tr>

<td style="width: 140px;">Name</td>

<td style="width: 200px;">Kundennummer</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="font-size: 10px">

<tr>

<td style="width: 140px;">

<%# DataBinder.Eval(Container.DataItem, "name")%>

</td>

<td style="width: 200px;">

<%# DataBinder.Eval(Container.DataItem, "kundennummer")%>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

DataSource Definition:

<asp:LinqDataSource ID="Customers" runat="server" ContextTypeName="DataAdapterRR.CustomerDB_ConnectorDataContext"

OrderBy="name" TableName="kp_customerdata">

</asp:LinqDataSource>

Nothing happeing in code behind.
The sarch on the datavalue works and data is shown in the dropdown.
Is there a way I can make the combo to search in all colums but display only the "name" once selected?

drag and drop in RadTreeView replaces template with text

Hi, I am trying to get client-side drag-n-drop working for a RadTreeView. Each node is templated. When I drag a node, the drag-n-drop works fine, but the node looses it's template and instead displays the fully qualified name of the data bound object in plain text (all client-side; no AJAX yet). Here is my code. See the attachment for how the tree looks *after* I drag and drop nodes (fully qualified names blurred).

    
            Telerik.Web.UI.RadTreeNode.prototype.insertBefore = function(destinationNode) { 
        
                var parent = destinationNode.get_parent(); 
        
                var index = parent.get_nodes().indexOf(destinationNode); 
        
                parent.get_nodes().insert(index, this); 
        
            }; 
        
            Telerik.Web.UI.RadTreeNode.prototype.insertAfter = function(destinationNode) { 
        
                var parent = destinationNode.get_parent(); 
        
                var index = parent.get_nodes().indexOf(destinationNode); 
        
                parent.get_nodes().insert(index + 1, this); 
        
            }; 
        
            Telerik.Web.UI.RadTreeNode.prototype.positionRelativeTo = function(destinationNode, dropPosition) { 
        
                switch(dropPosition) { 
        
                    case "over": 
        
                        destinationNode.get_nodes().add(this); 
        
                        break; 
        
                    case "above": 
        
                        this.insertBefore(destinationNode); 
        
                        break; 
        
                    case "below": 
        
                        this.insertAfter(destinationNode); 
        
                        break; 
        
                    default: 
        
                        break; 
        
                } 
        
            }; 
        
            //actual client event handler 
        
            function nodeDropping(sender, eventArgs) { 
        
                var source = eventArgs.get_sourceNode(); 
        
                var destination = eventArgs.get_destNode(); 
        
                var position = eventArgs.get_dropPosition(); 
        
                sender.trackChanges(); 
        
                source.positionRelativeTo(destination, position); 
        
                sender.commitChanges(); 
        
            }

Thanks!
