The issue is observable when AJAX is enabled using asp:UpdatePanel, telerik:RadAjaxPanel, or telerik:RadAjaxManager because the event handlers are not added back to elements upon an AJAX postback. When no AJAX panels are used, the entire document is rendered, and all handlers are attached to elements again.

 

Reproduction

  1. Add the code listed below to a page
  2. Load the page for the first time.
  3. Open the Chrome DevTools and monitor the Console tab.
  4. Click on the page anywhere except the button, the console will show 'Document clicked'.
  5. Click on the Button to perform an AJAX post back.
  6. At this point, the click event handler attached to the document no longer exists. Clicking anywhere on the document will not log the message in the console anymore.

Code

<asp:UpdatePanel runat="server">
    <ContentTemplate>
        <telerik:RadAutoCompleteBox ID="RadAutoCompleteBox1" runat="server"></telerik:RadAutoCompleteBox>
        <asp:Button ID="Button1" runat="server" Text="Post Back" />
    </ContentTemplate>
</asp:UpdatePanel>

<script>
    $(document).on('click', function (e) {
        console.log('Document clicked');
    });
</script>

Hi 

I have a RadEditor control where some toolbar functionalities are not working.

After searching for a possible reason, I used the OnClientCommandExecuting client-side event and noticed that sometimes, instead of the args with its value, I found the item of a RadTreeList control present on the page.

I tried to reproduce the issue by inserting an Editor and a TreeList on a page. I write some text in the Editor and try to change the color or background. Not always (and I can't figure out when), but sometimes the args are incorrect.

For example, if I open a node of the tree, the error is almost certain after that.

I send you an image of my javascript debugger.

I don't know what I can do, do you have any ideas?

Thanks

Michela

When on an Android mobile device, dragging the Splitter SplitBar moves a small part of the Splitter and the page itself. The issue can be observed on the Splitter Demo when accessed from a phone.

The bottom part of the last page of the PDF document stays hidden. If dragged with the mouse, the Page will move and can be viewed, releasing the mouse will scroll it back as a result, hiding the bottom part.

Issue can also be observed with the following demo: https://demos.telerik.com/aspnet-ajax/pdfviewer/overview/defaultcs.aspx

Hi Telerik Team,

I have encountered a strange issue while working with RadEditor in Track Changes mode, specifically when editing tables. When deleting content inside a table cell, the entire cell behaves abnormally—either disappearing visually or causing layout disruptions. I have attached a screenshot to illustrate the issue.


Steps to Reproduce the Issue:

  1. Enable Track Changes mode.
  2. Insert a table with at least 3 columns and multiple rows.
  3. Type some content into different cells.
  4. Delete the content inside one of the table cells.
  5. The cell appears to be deleted or behaves unexpectedly instead of just removing the text inside.

Hi,

I am contacting you today to let you know I have found cross-site scripting vectors within the latest version of the RadEditor. I have attached images of the payloads that seem to bypass the XSS filter.

The second payload only works on Firefox browsers, but the first works on Chrome browsers too. While it still requires users to click on the link to trigger XSS, it can be easily social engineered in most situations.

Upon inserting a new record after filtering on the Grid with No records, the exception "No property or field 'Name' exists in type 'DataRowView'" is thrown.

Steps to reproduce:

  1. Bind the Grid to an empty data source at initial load
  2. Filter any column
  3. Insert a new record

Code to replicate the issue:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" AllowFilteringByColumn="true"
    OnNeedDataSource="RadGrid1_NeedDataSource" OnInsertCommand="RadGrid1_InsertCommand">
    <MasterTableView CommandItemDisplay="Top" DataKeyNames="ID">
        <Columns>
            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>
            <telerik:GridButtonColumn CommandName="Delete"></telerik:GridButtonColumn>

            <telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID" ReadOnly="true"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" />

            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name"
                AutoPostBackOnFilter="false" />

            <telerik:GridBoundColumn DataField="Category" HeaderText="Category" UniqueName="Category" DataType="System.String"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" />

            <telerik:GridBoundColumn DataField="Price" HeaderText="Price" UniqueName="Price"
                CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" DataFormatString="{0:C}" />
        </Columns>
        <EditFormSettings InsertCaption="Add New Item" />
    </MasterTableView>
</telerik:RadGrid>

 

C#

private const string DataTableSessionKey = "RadGridDataTable";
private DataTable SessionDataSource
{
    get
    {
        DataTable dt = Session[DataTableSessionKey] as DataTable;

        if (dt == null || !IsPostBack)
        {
            // Create an empty DataTable with schema defined
            dt = new DataTable();

            dt.Columns.Add("ID", typeof(int));
            dt.Columns.Add("Name", typeof(string));
            dt.Columns.Add("Category", typeof(string));
            dt.Columns.Add("Price", typeof(decimal));

            dt.PrimaryKey = new DataColumn[] { dt.Columns["ID"] };

            Session[DataTableSessionKey] = dt;
        }

        return dt;
    }
}
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    (sender as RadGrid).DataSource = SessionDataSource;
}

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)
{
    GridEditableItem insertItem = (GridEditableItem) e.Item;

    Hashtable newValues = new Hashtable();

    insertItem.ExtractValues(newValues);

    DataRow findLastItem = SessionDataSource.Select("ID=MAX(ID)").FirstOrDefault();

    newValues["ID"] = findLastItem != null ? (int) findLastItem["ID"] + 1 : 0;

    DataRow rowToInsert = SessionDataSource.NewRow();

    foreach (DictionaryEntry entry in newValues)
    {
        rowToInsert[entry.Key.ToString()] = entry.Value ?? DBNull.Value;
    }

    SessionDataSource.Rows.Add(rowToInsert);

When a TabStrip has Keyboard navigation active, the focus CSS class (rtsFocused) is not removed from the previously active tab when clicking on other tabs with the mouse.

<telerik:RadTabStrip RenderMode="Lightweight" ID="RadTabStrip1" runat="server">

When no keyboard navigation is used, the behavior is acting correctly.

When the JAWS screen reader is used alongside the Grid with enabled keyboard navigation, using Alt + Up/Down arrow doesn't work as intended, most noticeably trying to use Alt + UpArrow doesn't move the focus to the previous row. 

This behavior can be observer on the Keyboard navigation demo as well

Steps to reproduce

  • Open the AJAX theme builder
  • Select a theme - doesn't matter if it's Default or Bootstrap or whatever
  • Click Start Theming
  • Click Download
  • Name the download
  • Open/extract the zip

When the zip is opened with SecureZip, it reports 9 errors. When extracted with any zip utility, there are duplicate files in the zip. I think the files should be in folders within the zip. Attached is one such file. I've tried this several times with different base themes.

For RadGrid, after setting EnableKeyboardShortcuts to false, I find the Up/Down keys are also disabled. However, according to your online document below, the Up/Down keys shouldn't be disabled in this case.

According the Keyboard Support online demo, these buttons should not get disabled:

"The grid also features an additional property ClientSettings -> KeyboardNavigationSettings -> EnableKeyboardShortcuts which when set to false will disable all keyboard navigation shortcuts except for the Up/Down and Page Up/Page Down keys."

.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource

Steps to reproduce:

  • Make any change to the first record, such as modifying the Contact Name.
  • On the second record, Click the "x" under the DELETE column to mark it for delete.
  • Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())
  • Choose to Cancel at the popup prompt.
  • Click "Save changes".
  • Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.

Using the set_value() method of the DatePicker's Input, set "2024-05-08" (the date format is dd/MM/yyyy), the month and day are misplaced and the control gets the wrong date of 05/08/2024.

When the day is larger than 12, the correct date is received. For example,  '2024-05-14' will update the control correctly and we see the control with 14/05/2024.

An unwanted second captcha is being created and the UI does not update when the second captcha is created.  There are no other Ajax calls on the page that are causing this issue.

We have extended the BaseCaptchaCachingProvider and are now saving the image in the database. After making this change, the image is no longer grayed out; however, validation only succeeds after every three attempts. When we check the database, we notice that a second key with a different image has been added before the user clicks the submit. On the user interface, we still see the old image.
