Please add support for tags in exported PDF documents. We need these tags for accessibility purposes. Currently, when we export a PDF from a RadGrid, it is created without any tag structure, which can make it difficult for a screen reader to process correctly.

Resizing a column in the Grid Leads to resizing of the Grid wrapper along with the GroupPanel. The problem can be replicated with the following Resizing settings:

<Resizing AllowColumnResize="true" AllowRowResize="true" EnableRealTimeResize="true" ResizeGridOnColumnResize="false" EnableNextColumnResize="true"/>

The issue occurs only on certain Screen sizes, or when the browser/display has some zoom applied.

RadImageGallery is a great control and supports many image formats out of the box (JPEG, PNG, BMP, etc.)

However, it does not provide native support for HEIF.  HEIF is now the default format for most Apple devices (anything after iOS 11 update).

It would be great if RadImageGallery were updated to provide support for this format so that developers don't have to force image conversions of photos taken by Apple devices.

Code & steps to replicate the issue.

1. At the initial load, the TargetButton is enabled.
2. Click the "Toggle Enabled State and Do PostBack" which will disable the button using the set_enabled property and do a PostBack. 
3. Click again on the "Toggle Enabled State and Do PostBack" to enable the TargetButton and do another PostBack.
4. While the TargetButton gets enabled via JavaScript, the server still renders the Button as disabled after the PostBack.

<telerik:RadButton runat="server" ID="RadButton1" Text="Target Button" AutoPostBack="true" EnableViewState="true" />
<br />
<br />
<telerik:RadButton runat="server" ID="RadButton2" Text="Toggle Enabled State and Do PostBack" OnClientClicked="toggleEnabledState" AutoPostBack="true" />

<script>
    function toggleEnabledState(sender, args) {
        var radButton1 = $find("<%=   RadButton1.ClientID %>");

        radButton1.set_enabled(!radButton1.get_enabled());
    }
</script>

Using the latest 2022.3.1109.45, our web application is catching "Invalid Resource Request" exceptions when the Windows7 or Vista (maybe others too) loads the "Editor" control in "Classic" mode.    By decoding the URL, the control is having problems locating the image below

WebResource.axd?d=ZHkUja8e5EF7zNoz8IiY_kAGH7MBQgCnq0BEYT2AtFLv57GDfGbEymwRG8H68WuiE_6l2fpZpqb_FzVc_OItknX-LMTzvQOwC0Mk8HaCtGvNzWl-5nNlZ6xpbOjNSk4A0QtPGtyV0UA-BWX4bOfPU8EI30eAVg8UO6p7yERiuEbCUoiZOGUevYGPdrNVvPel0&t=638034624000000000

Change the skin of the radeditor in the default.aspx to another skin such as "metro" and the problem will not happen.    It works OK at least on Black, Metro and Silk but haven't tested others, you can tell it doesn't work when the divider bars in the editor toolbar don't appear properly.

When a big number of items are bound to RadGrid on the server side and Virtualization is enabled paging to the last item is not working as expected.

The problem can be reproduced with the setup in the following demo:

• https://demos.telerik.com/aspnet-ajax/grid/examples/performance/virtualization/defaultcs.aspx 

Increasing the number of Customers bound to the Grid to more than 1000000 leads to the problem.

The Window will not open in the center of the screen if it was already opened once and the page has been scrolled. It seems that the Window keeps opening at the same position initially was opened, hence it could open out of screen bounds.

Steps & Code for Reproduction

1. Copy/Paste the Code from below and Load the page
2. Click on the Button, the Window will open at the center
3. Scroll toward the top of the page until the button is barely visible
4. Click the button again. At this point, the Window will open out of the screen boundaries, in its initial position

Code

<style>
    .mydiv {
        margin: 2000px 100px;
    }
</style>

<telerik:RadWindow ID="RadWindow1" runat="server">
    <ContentTemplate>
        <h3>RadWindow1 Content</h3>
    </ContentTemplate>
</telerik:RadWindow>

<script>
    function ShowEditForm(sender, args) {
        var wnd = $find("<%= RadWindow1.ClientID %>");
        wnd.show();
    }
    Sys.Application.add_load(function () {
        setTimeout(function () {
            $telerik.$('.mydiv')[0].scrollIntoView();
        }, 100)
    });  
</script>

<div class="mydiv">
    <telerik:RadButton runat="server" ID="RadButton1" Text="OpenWindow" AutoPostBack="false" OnClientClicked="ShowEditForm" />
</div>

Similar to the property in the ComboBox

select an item from the dropdown, different than "1"
expected: buttons become enabled
actual: radbutton is still disabled
<asp:Button ID="ButtonTest" runat="server" enabled="true" Text="Test" EnableViewState="False" />
<telerik:RadPushButton ID="RadButtonTest" runat="server" Text="RadButtonTest" Enabled="True" EnableViewState="False" RenderMode="Lightweight"></telerik:RadPushButton>

    <Items>
        <asp:ListItem Text="1" Value="1"></asp:ListItem>
        <asp:ListItem Text="2" Value="2"></asp:ListItem>
        <asp:ListItem Text="3" Value="3"></asp:ListItem>
        <asp:ListItem Text="4" Value="4"></asp:ListItem>
    </Items>
</asp:DropDownList>
 
protected void Page_LoadComplete(object sender, EventArgs e)
{
    if (DropDownTest.SelectedValue == "1")
    {
        ButtonTest.Enabled = false;
        RadButtonTest.Enabled = false;
    }
    else//workaround
    {
        string script = string.Format("function f(){{$find('{0}').set_enabled({1});Sys.Application.remove_load(f);}}Sys.Application.add_load(f);",
                                            RadButtonTest.ClientID,
                                            "true");
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "someKey", script, true);
    }
}

protected void SelectedIndexChanged_Test(object sender, EventArgs e)
{
}

Repro: 

<telerik:RadStyleSheetManager runat="server"></telerik:RadStyleSheetManager>

<asp:UpdatePanel runat="server">
    <ContentTemplate>
        <asp:Button Text="Postback" OnClick="Unnamed_Click" runat="server" />
        <telerik:RadButton runat="server" Visible="false" ID="RadButton1" Text="Telerik button" AutoPostBack="true" />
    </ContentTemplate>
</asp:UpdatePanel>

protected void Unnamed_Click(object sender, EventArgs e)
{
    RadButton1.Visible = true;
}

<add key="Telerik.ScriptManager.EnableHandlerEncryption" value="true" />

Workaround:

Temporarily set EnableHandlerEncryption to false or do not use a StyleSheetManager

<add key="Telerik.ScriptManager.EnableHandlerEncryption" value="false" />

Hello,

I can't tell you how long we've racked our brains trying to figure this issue out. We are using the Bootstrap theme for RadListView and are doing drag and drop. We've been getting a "This is an invalid webresource request. " error when first dragging an item on the page.

I just came across this article which provided me some new guidance:
https://feedback.telerik.com/aspnet-ajax/1586960-windows7-and-vista-skins-generate-application-error-when-using-editor-control

And we decrypted the querystring of the WebResource request and it is looking for this:

pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Bootstrap.ListView.drag.gif

When we change our RadListView skin to "Default" or "Black", this drag and drop error is gone so there clearly must be a broken link/reference for that image because we also see the little drag and drop cross overlaying the items we are dragging.

Thank you,

Curtis

Hi,

currently the only way to set the translation for the "All" option that is created through the enabled "EnableAllOptionInPagerComboBox" property is to set the translation in the "RadGrid1_ItemDataBound" method, which is described here: Localization on RadGrid: Paging Option All

It's a workaround for a missing localisation. By setting the translation in the RadGrid1_ItemDataBound method the if-statement is being checked for every row processed, which is not good for performance.

Could you please make it possible to set the translation with a property and have the default value set in the resource file of the grid?

Thank you.

Due to recent changes to the keyboard accessibility of the RadMenu (i.e. it is now only accessible using the arrow keys instead of moving around using tabs), mega menus are no longer keyboard accessible.

We have designed a mega menu using a telerik RadSiteMap embedded in a RadMenu control, as suggested in the Telerik Demo site: http://demos.telerik.com/aspnet-ajax/menu/examples/megadropdown/defaultcs.aspx

However, this is no longer accessible. Previously, you could open the dropdown by pressing the down button, then move around in the dropdown using tab. Now, however, pressing tab just closes the dropdown.

We need the menu to be accessible in one way or another.

Instead of having the property to select single or multiple it would be more productive to have a property called SelectCount and we can enter the amount of listings to be selected. If its a single I select 1... for multiple I select how many I need. No more need for the Single/Multiple property except for backward compatibility.
