Questions on UI for ASP.NET AJAX Forum

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

Validation on Selction with RadUpload.

HI Team,

I need to Validate a textBox if the RadUpload.UploadedFiles.Count !=0

Something Like this...
if (RadUpload.UploadedFiles.Count !=0)
then Validate TextBox should not be empty
if (RadUpload.UploadedFiles.Count ==0)
then TextBox can be empty.

And can we do this without post-back. Something on Client Side please.. Using JavaScript preferably...

Thanks,
Raja

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.

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.

Scheduler Confirmation Delete Position

Posted on Mar 1, 2010 (permalink)

Hi,

Is it possible to make the confirmation delete box to be displayed just beside the appointment to delete or at center of the screen?

Because if I have a scheduler page that is in full view (24 hrs) and I try to delete the meeting at 8AM, the confirmation box is in the center of the scheduler and we have to Scroll it down to click on OK.

we are using version "2011.1.519.40" of the dll Telerik.web.ui.

Thanks,

Mayur

radeditor does not work in iOS5

Hi, I upgraded my iPad to iOS5 this morning. I note that the upgrade allows the contenteditable property to work in the default safari browser on the iPad, so in theory this should mean that you can now use RadEditor on it. I tried the demos on this website and none of them work. Other rich text editors like CKEditor do work fine in iOS5 though.

Is there a css hack or workaround to get the editor working on the ipad or do we need to wait for Q3 2011 before this will be available?

thanks.

Questions about pdf exports

Hi,

I am doing some works with RadGrid to export pdf format, have questions:
(1) Is there a way to output graphics in pdf's header area? I tried to use html img tag in PageTitle property without success
(2) Is there a way to output "Page x of y"? I would prefer to output this into footer area.
(3) I can not get rid of page margins on header and footer areas no matter what values I set PageTopMargin and PageBottomMargin properties to. PageRightMargin and PageLeftMargin seem to function well.

TIA
