Clear focus on edited item when prepopulated

I have a grid that, upon new or edited record displays GridNumericColumns with partially prepopulated values (e.g. 1234).

When clicking the cell, the prepopulated value is highlighted. Any typing will clear the prepopulated value. I don't want that.

Ideally, I'd like the cursor to position after the partially prepopulated value when the user clicks the cell, so they can complete the value (e.g. 12345678).

Any ideas?

Is there a way to center the RadGrid Edit Popup Window in the browser window? I have found a way to center it in the RadGrid, but I would prefer it to be in the center of the whole web page.

Thanks.

Disappearing Pager?

I set the AlwaysVisible property on the MasterTableView, but I also set the Position to be Top and Bottom. When the PageSize is greater than the record count and there is only 1 page of data (PageSize is 10, but 4 records are returned) the pager only displays at the bottom. I would like the Pager to either display top and bottom OR allow for the section where the pager resides to be available to the user to display page count and record count (4 records).

How can I provide this? It seems like "something is missing" when the pager doesnt display in with records less than the page size.

Thanks,

Grid

Using a Web Service to populate RadGrid

Hello.

In order to familiarize with the RadGrid component, I have created a small application whose grid is populated by a web service.

Default.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadGrid ID="RadGrid1" runat="server">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn DataField="ID" HeaderText="ID" DataType="System.Int32" />

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" DataType="System.String" />

</Columns>

</MasterTableView>

<ClientSettings>

<DataBinding Location="WebService.cs" SelectMethod="RetrieveRows" />

</ClientSettings>

</telerik:RadGrid>

</form>

</body>

</html>

WebService.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.ServiceModel;

using Telerik.Web.UI;

namespace WebApplication1

{

[ServiceContract(Namespace = "")]

[System.Web.Script.Services.ScriptService]

public class WebService

{

public WebService ()

{

}

[OperationContract]

public Dictionary<string, object> RetrieveRows(int startRowIndex, int maximumRows, List<GridSortExpression> sortExpression, List<GridFilterExpression> filterExpression)

{

Dictionary<string, object> dictionary = new Dictionary<string, object>();

dictionary.Add("Data", new[] { new { ID = 1234, Name = "Test" }});

dictionary.Add("Count", 1);

return dictionary;

}

The compilation was successful, but the following error message was displayed at runtime by the built-in script debugger of Internet Explorer:
Line: 6563
Error: Sys.ArgumentException: Cannot deserialize empty string.
Parameter name: data

I would appreciate whether some assistance could be provided to solve this problem.

Last but not least:
a) I was wondering how the application could be implemented using a server-side binding solution.
b) What is Telerik's recommendation in regard to client versus server-side binding implementations using a web service?

Thank you in advance.
Paulo

RadTextBox casues validation errors

I have been searching all over for an answer to this but to no avail... I am hoping someone here can help me.
I have a form that is intended to send field information to a support email address. I have disabled validation on all of the controls on this form to troubleshoot this.
When i fill the form out and click submit, it works fine, i get my Email as expected...

However, if i have special characters in any of the radtextbox fields, i get a validation error. Just the simple phrase <ValidateThis> will break the page.

Now i have created a routine to clean the text and replace the characters which ascii equivalents but the problem is that the validation error occurs before anything is run. How do i intercept this?

Thanks
Phil
