Hi,

I experience rather low quality results on scaling hires JPG image (2900x2900) to a size of 400x400

I can find that InterpolationMode.HighQualityBicubic is used but from my point of view the result should be better then.

Where can I send source photo (3.3MB), just try to scale to 400x400 and you 'll see what I mean.

Something changed in the scale procedure?

Telerik Grid Setting working with a web-site project but not with a web-application

I have a web-site project that I needed to convert to web-application. After I resolved all the compilation errors I hit a runtime exception in a piece of code I got from Telerik's Website.
In the part where I de-serialize the grid settings data I get an exception

System.ArgumentExceptionHResult=0x80070057Message=The serialized data is invalid.Source=BMS.WebAppInner Exception 1:SerializationException: Unable to find assembly 'App_Code.5gd62bdt, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

public static GridSettingsCollection LoadFromSerializedData(string data)

{

LosFormatter formatter = new LosFormatter();

// the line that throws the exception: formatter.Deserialize(data)

return (GridSettingsCollection)formatter.Deserialize(data);

}

This works no problem when it was a Web-Site project. I am guessing assemblies that start with an App_Code.* usually means that it is compiling at runtime. I tried clearing all the ASP temp folders.

Any help is greatly appreciated. Thanks.

Hide duplicate values in RadGrid column

I want to bind the grid to query results.
A person might appear several times and I want to sort the results using person ID.
Is there a way to hide duplicate values (e.g. ID, First name, Last name etc.) in the grid?

I wish there was a property like 'HideDuplicates' in MS Access.

Close RadMenu on client click

Hello,

When I click on a RadMenuItem of a regular RadMenu (not context menu), the menu is not closed.
I try to add some code in the ItemClicked event :
sender.close();
or even:
setTimeout(function() {sender.close();}
But it doesn't work since the menu is reopened just after the close because of a delayed event.

Does anybody have an idea.

Thanks in advance.

BR, Laurent

Export to PDF- with a Rad Grid and asp.net grid using ItextSharp

I have an aspx page that contains an asp.net grid created from codebehing and rendered on pageload. This acts as the header for a RadGrid that contains the detail. Both the grids are in separate pannel.
I am using iTextSharp to export both the grids into a pdf. I am using the code below to create a form dynamically and then rerender it into a pdf:

HtmlForm

form = new HtmlForm();

form.Controls.Add(MyRadGrid1);

StringWriter sw = new StringWriter();

HtmlTextWriter hTextWriter = new HtmlTextWriter(sw);

form.Controls[0].RenderControl(hTextWriter);

I am getting several errors during the 'form.Controls[0].RenderControl(hTextWriter)' .
This code is unable to render all the telerik controls in the RadGrid.

Is there any other way that this could be achieved? Should i look into other options that will be better than itextSharp ?

Thanks in advance.

Problem with RadGrid

Hello!
I have a grid with frozen columns and grouping. When the grid loads without horizontal scrolling and has hidden columns, I discovered two problems:
1) after displaying hidden columns manually and when horizontal scrolling becomes available - we can scroll the grid data, but the grid headers do not scroll
2) the “colspan” parameter is incorrectly calculated if some columns were hidden when the page was loaded.

it is my .aspx code:

I do not know which parameter makes these changes, can you help me?

I am using the latest version of Telerik - 2019.1.215.45

Upgrading RadFilter from Pre-2010.3.1109

I have been using the 2010.1.415 release of the RadFilter for some time now. As I look to upgrade to the latest release (2011.1.413), I've run into a problem where the RadFilter cannot load a previously saved state from the database. It looks to be the same issue as detailed here - that is, as of the Q3 2010 release (2010.3.1109), there is now a new way to save state.

I currently have customer RadFilter settings saved in a database. How can I upgrade this data to be compatible with the latest release?

Unable to show RadAjaxLoadingPanel as $find is not working

Hi there,

Bit of an odd problem here: I have a RadAjaxLoadingPanel that I want to display when I'm doing some client-side declarative data binding (http://demos.telerik.com/aspnet-ajax/grid/examples/client/declarativedatabinding/defaultcs.aspx). According to this http://www.telerik.com/help/aspnet-ajax/ajax-show-hide-loadingpanel.html , I can show and hide it via JavaScript. I've hooked into the RadGrid's client events of OnDataBinding and OnDataBound to show and hide the loading panel respectively.

Here are the two relevant JS functions, which are in a RadScriptBlock:

var currentLoadingPanel = null;

var currentControl = null;



function ShowLoading() {

currentControl = $find("<%= uxRGC.ClientID %>");

currentLoadingPanel = $find('<%= RadAjaxLoadingPanel1.ClientID %>');

currentLoadingPanel.show(currentControl);

}

function HideLoading() {

if (currentLoadingPanel != null) {

currentLoadingPanel.hide(currentUpdatedControl);

}

currentUpdatedControl = null;

currentLoadingPanel = null;

}

The odd thing is, the $find for RadAjaxLoadingPanel1 does not find the control, i.e. it comes back as null. I get the currentControl, which is the RadGrid, but not the loading panel. If I use document.getElementById, it finds the control but show(xyz) isn't supported.

I'll just mention that the grid, loading panel and script block are in a ASP.Net .ascx control, which gets loaded onto a content page inside a master page.

Thank you,

Mike K.
