A JavaScript error is thrown when the Print dialog is being disposed.
Error message:
Uncaught TypeError: Cannot read property 'dispose' of undefined

    at $IE.Print.dispose (<anonymous>:90:18)

 

Workaround:
Enable the external dialogs of the Editor/ImageEditor and modify dispose() function of the Print.ascx dialog:

 

Print.ascx

				dispose: function ()
				{
					this._attachHandlers(false);

					this._printBtn.dispose();
					this._cancelBtn.dispose();

					$IE.Print.callBaseMethod(this, "dispose");
				},

We recently added row group functionality to our grids and we and our users are very happy with this.

 Only thing that bothers us is the drop functionality on the grouppanel. We an issues to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns.

The drop marker indicated the new column to group will be added in front, but the column is added to the end of the grouped columns.

Forum reference:

This is reproducible in the demo on your site. See also the added video.

Just updated the controls and as usual got bitten by the change.  Very simple, we had a button that changed colors based on a change in an edit page.  The Button remained a White Color if nothing was entered, a Green Color if the fields were all correct and a Red Color if the fields were in error.  The determining factor is all behind the seen analysis on a save which has nothing to do with the Button.  Code behind the scenes sets a db value for the status of the Button. We know that the status is being set correctly because activity allowed or disallowed occurs correctly and that the DB settings having been checked are 100% correct as well.

There are seven Buttons with 7 Entry Pages that are affected and the users are totally confused when there is no visual direction as to the problem.

How do we Fix the Button to change Colors

See online demo:

https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

 

Steps to reproduce (seen in Chrome and Edge):

- Click the "x" on the 2nd to last record on page 1 to mark it for deletion  (Click "OK" at the prompt)

- Click "Add new record" button

 

Observe:

 - the record marked for deletion moves up by one record (but fortunately it appears the correct record will actually get deleted upon Saving)

 - a blank new record is creating correctly

 

If you repeat this procedure but choose a different record for deletion you can see it is functioning correctly.

 

I am seeing the same behaviour in my own project.

Release R1 2020

This bug started happening in version Telerik 2019.3.917, and is still present in Telerik 2019.3.1023.

The reproduction is extremely basic:

<table runat="server">
    <tr>
        <td>Month/Year:</td>
        <td>
            <telerik:RadMonthYearPicker ID="MonthYear" runat="server" Width="150px">
            </telerik:RadMonthYearPicker>
        </td>
        <td>
            <asp:Button ID="btnGenerate" runat="server" Text="Get Report" OnClick="btnGenerate_Click" />
        </td>
    </tr>
</table>

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            MonthYear.SelectedDate = DateTime.Today;
            MonthYear.MaxDate = DateTime.Today.AddDays(1);
        }
    }

When i select a month/date from the control and submit the page i'm getting this script error:

The page freezes and i can get this error in Chrome from browser right-click->inspect->Console tab

You can see at the base of the call stack that the RadMonthYearPicker control is referenced.

.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.

There is a black line that has appeared in my RadMenu.

The problem can be solved by adding a display: none in the following class:

.RadMenu .rmGroup:before, .RadMenu .rmMultiColumn:before, .RadMenu .rmScrollWrap>.rmHorizontal:before, .RadMenu .rmScrollWrap>.rmVertical:before

RadCodeBLock and RadScriptBlock is not able to handle the server tags for all case scenarios, hence RadAjaxManager throws the exception mentioned in the title.

In WebService binding scenario, the text of the items is not encoded and HTML code might get executed. 

In Server-side Load on Demand binding this is not observed. 

The following code can be used as a temporary workaround for WebService binding scenario: 

<script type="text/javascript">
    Telerik.Web.UI.RadComboBoxItem.prototype._renderItemContent = function (d) {
        if (this.get_imageUrl()) {
            this._renderImage(d);
        }

        //https://stackoverflow.com/questions/6234773/can-i-escape-html-special-chars-in-javascript
        function escapeHtml(unsafe) {
            return unsafe
                    .replace(/&/g, "&amp;")
                    .replace(/</g, "&lt;")
                    .replace(/>/g, "&gt;")
                    .replace(/"/g, "&quot;")
                    .replace(/'/g, "&#039;");
        }

        d[d.length] = escapeHtml(this.get_text());
    }
</script>

To replicate the problem:

  1. Create RadGrid and bind it a datasource
  2. Set ClientSettings - Selecting - AllowRowSelect to true
  3. Set ClientSettings - EnablePostBackOnRowClick to true
  4. Add a GridEditCommandColumn or a ButtonColumn with Edit/Save/Cancel CommandNames
  5. Enable AJAX for the Grid
  6. Run the application in FireFox

Clicking on the Edit button fires the RowClick event of the Grid instead of Edit/Save/Cancel.

Hi, I have trouble with RadScriptManager. I would like combine scripts on page to only one file. But when I enabled it, my site threw javascript error on loading.
Please help me fix it, it would also be better if you can help me understand what happened.

First image is what I set up for RadScriptManager

Secondary image is the error.



I have no idea what's Telerik.Web.UI.Point, I haven't used it anywhere.

Please help me get this error out & fix it.
Thank you.

We suspect a bug of Telerik controls:

 

Bug of Telerik: PageView.set_contentUrl(MyUrl) method - call MyUrl twice if RadTabStrip and RadMultiPage is inside RadAjaxPanel control. Firefox only.

Code: http://bit.ly/2NVbm8Z

It enter here two times: http://bit.ly/2NZ0cQH

 

If try it in chrome - request goes only one time.

If remove RadAjaxPanel - also request goes only one time.

 

Is it bug of your Controls?
