Web References VWD2010 Express

I'm trying to feed live data from my sql server to a radgrid.

I'm using VWD2010 Express and I created a Web Service and then referenced that service in my project. However, the project will not build because of the attached error.

could not find sgen.exe using the sdktoolspath

If this problem can not be fixed, is there another way that I can stream live data from my sql server to the radgrid. I want to be able to see all records even as records are added from many different sources without having to refresh. Ideally, as quickly as displayed in this http://demos.telerik.com/aspnet-ajax/grid/examples/client/livedata/defaultcs.aspx example.

AdvancedEditTemplate user control postback

Dear TELERIK,

I'm using custom user control as AdvancedEditTemplate in RadScheduler.

This user control has COMMIT and CANCEL buttons - both server side ones, with different command names: "Update" and "Cancel".

But I'm also planning to add some server side data validation in the user controls's code behind.

Imagine the COMMIT button had been pressed and then my server side validation passed UNsuccessfully.
Is it possible to avoid closing of the AdvancedEditTemplate pop-up, in the same way as if CANCEL button was pressed?

Many thanks!

- Stepan.

Serialization Error

I am using AjaxManager with a farily complex page. It's sometimes tough to reproduce, but I get a serialization error at the end of a request, during the response back to the client after all of my server code has run. It is within some Telerik code. The odd thing is that once I do a full page refresh, it doesn't happen again.

Any help you can provide will be greatly appreciated.

AfterClientCheck and AfterClientClick not firing/hitting correct js function

I'm trying to use the AfterClientCheck javascript event on a simple test page in a VS2008 test project, but it's not working. OnClientMouseOver is working just fine, so javascript is working.

Any thoughts?

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="myNamespace.WebForm1" %>

<!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>

<script type="text/javascript">

function test(input, args) {

alert("test");

}

function AfterCheckHandler(node) {

alert("You have checked " + node.Text + " which is now " + node.Checked);

} function AfterClickHandler(node) {

alert(node.Text);

}

</script>

</head>

<body>

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

<div>

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

</telerik:RadScriptManager>

<telerik:RadTextBox ID="RadTextBox1" runat="server" ClientEvents-OnKeyPress="test">

</telerik:RadTextBox>

<telerik:RadTreeView ID="RadTreeView1" CheckBoxes="True" runat="server" AfterClientClick="AfterClickHandler"

AfterClientCheck="AfterCheckHandler" OnClientMouseOver = "test">

<Nodes>

<telerik:RadTreeNode runat="server" Text="Books" ExpandMode="ClientSide">

<Nodes>

<telerik:RadTreeNode runat="server" Text="Fiction">

</telerik:RadTreeNode>

<telerik:RadTreeNode runat="server" Text="Non-Fiction">

</telerik:RadTreeNode>

</Nodes>

</telerik:RadTreeNode>

</Nodes>

</telerik:RadTreeView>

</div>

</form>

</body>

</html>

As you can see, I used one of the simple samples and only added the events I was interested in to test them.
Thanks

Row Disappear on page refresh

So I'm adding a new row to my radgrid.

Then, after I finish inserting the row... I press F5 to refresh the page and my most recently entered row disappears! I'm doing this in debug and running it off my local machine.

If I stop debugging, stop the development server, and then press play to debug...the row appears! However the same thing happens with the next row I insert if I refresh the page again.

I talked with a co-worker about this and he seemed to think it has something to do with the viewstate. Regardless... we're having trouble figuring it out. It's like something is not getting refreshed with my radgrid when the page refreshes.

Any help is greatly appreciated.

[Solved] FilterExpression issue - ToList vs Not ToList

Can someone explain why FilterExpression is LINQ syntax for List but SQL syntax for others.

Here is what I have tested:

public class TheData

{

public string Subject { get; set; }

}

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

{

MyEntity ent = new MyEntity();

IQueryable<TheData> gridData = from t1 in ent.Documents

join t2 in ent.Approve on t1.Id equals t2.DocumentId

where (t1.InsertById == 1 || t1.ApprovedById == 1)

select new TheData

{

Subject = t1.Subject

};

string filterExpression = RadGrid1.MasterTableView.FilterExpression.Replace(".ToString()", String.Empty);

RadGrid1.VirtualItemCount = filterExpression != string.Empty

? gridData.Where(filterExpression).Count()

: gridData.Count();

var testData = (filterExpression != string.Empty

? gridData.Where(filterExpression)

: gridData).ToList();

var finalData = (from f in testData

select new

{

Subject = f.Subject.Replace("someval", "tosomeval"),

}).ToList();

RadGrid1.DataSource = finalData;

}

If I call .ToList() for the finalData filterExpressions syntax is
(iif(Subject == null, "", Subject).Contains("sometext"))

but if I do not call .ToList() filterExpression syntax is
([Subject] LIKE '%sometext%')

PS: EnableLinqExpressions="true" doesnt reflect any changes.

TIA.
