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

Scrolling: static headers destroying layout

Hi,

I need to have static headers in my RadGrid. Here is the problem: My radgrid have width = 500px. When there is not enough rows for scroll to appear everything is fine. When I change data and there is more rows so scroll apears there are 2 strange things that occur:
1. radgrid width becomes about 520px and those 20 additional px initialy is only white column. Scroll is placed in width 480-500px.
2. when I move cursor over grid, scroll appears on this new white column.

When static headers are set to false, scroll behaves as expected. Issue occurs in IE 8 - browser that will be used by our client.

How can it be solved? I am attaching 4 photos. 1,2,3 are step by step description of problem, 4th is with static headers = false, represents what it would be expected to look like when problem is solved.

Regards,
Marcin

Uploading files AND form fields

Hi! Currently I'm planning a web application and I'm not quite sure, if the AsyncUpload component would satisfy my needs. Basically I'm trying to acomplish the following: - having multiple text input fields (e.g. for contact details) - allowing the user to upload multiple files at once - allowing the user to select multiple files at once if Flash or Silverlight is available - showing upload progress The operation doesn't need to be async but of course it would be nice if the upload could be started just after selecting files. I've already looked at the AsyncUpload examples but somehow I'm unsure if I can combine this component with regular form fields (and a submit-button). The regular RADUpload component could be easily used for that but in my understanding, it lacks the support of selecting multiple files because it doesn't use Flash/SL and selecting dozens of files one after another isn't an option for me... What do you think, can either of these controls work for me? chris
