Button with ContentTemplate RadConfirm callback in Firefox

I work on a large website that has many RadButtons with ContentTemplates, and uses a RadConfirm and callback functionality to confirm the user action and perform a PostBack. Recently, someone noticed that the JavaScript code inside the callback sender.click() does not work in Firefox.

This is a known bug, as documented here LINK

Great, so I've set about adding the Firefox-specific workaround, as seen in this demo. LINK

if (shouldSubmit) {

//initiate the original postback again

sender.click();

if (Telerik.Web.Browser.ff) {

sender.get_element().click();

}

Which works fine with normal RadButtons. But, I've found if the RadButton has a <ContentTemplate> declared, the postback is not executed, and the confirm keeps calling the OnClientClicking method which opens the RadConfirm again.

I've copied the code from this Demo into my own test page and reproduced the issue, it is very simple to reproduce. Simply add a ContentTemplate to the second button.

<telerik:RadButton RenderMode="Lightweight" ID="btnRadConfirm" runat="server" Text="RadConfirm" OnClientClicking="RadConfirm" OnClick="Button_Click">

<ContentTemplate>

Template

</ContentTemplate>

</telerik:RadButton>

And now the confirmation cannot cause a postback in Firefox. We are using Telerik version 2016.2.607.45

DatePicker ignores z-index?

I am opening a DatePicker from a asp:panel controlled by a modal popup extender. The datepicker is displaying behind the modal popup. I've added a CSS hack to kick up the z-index of the datepicker, and according to the dom inspector I'm using, the z-index of the datepicker is changing. But no matter how high I set that z-index, the datepicker continues to draw behind the modal popup.

Any ideas?

Run clientside javascript when RadEditor auto-sizes

I've tried following the directions in: http://www.telerik.com/forums/what-event-is-fired-on-resize but it doesn't appear that onResizeEnd is called when auto resizing.

I have the RadEditor inside a RadWindow and I need to run some javascript to resize the RadWindow when the RadEditor auto-sizes. Can I get some direction about what event to trap on so I can run my javascript to resize my Rad Window manually?

Thanks!

RadEditorStatistics off by One Character

I'm using the EditorModule RadEditorStatistics and it always returns one less character than what has actually been entered in the text box. I'm not sure if it's the way I've implemented it or if that is just the way it works. Any help would be appreciated. I'm including the markup and js I use. Any help would be greatly appreciated.

<telerik:RadEditor ID="redJustification" runat="server" EditModes="Design"

MaxTextLength="4000" SkinID="DefaultSetOfTools" ContentAreaMode="Div" OnClientInit="CharCountInit"

Allow html in some columns

Hi guys

I have a database that has been populated with raw html programmatically, but when I try to inline text-edit those fields to tweak content, it fails to 'Update' because the data in 2 columns contains some raw html. How can I tell radgrid to allow it for specific columns?

I (as webmaster) am not worried about users hacking because only I have (secured) access to this function.

Thanks for your help!

how to add ResourceStyleMapping from code?

first I have my RadScheduler in a page calling a webservice using a custom provider (MyDbSchedulerProvider)
I am adding dynamic category coloring to my appointments.
I was able to add them manually to the front code as

<ResourceStyles>

<telerik:ResourceStyleMapping Type="Calendar" Key="cat1" Text="category 1" BackColor="#DEB887" BorderColor="#000000" />

<telerik:ResourceStyleMapping Type="Calendar" Key="cat2" Text="category 2" BackColor="#000000" BorderColor="#FFFFFF" />

</ResourceStyles>

then in my provider code I tried a few things but only got this to work so far

Dim oResource As Resource

Select Case (i Mod 4)

Case 0

'apt.CssClass = "rsCategoryAqua"

'apt.BackColor = Drawing.Color.Aqua

'apt.ForeColor = Drawing.Color.Black

oResource = New Resource("Calendar", "cat1", "category 1")

apt.Resources.Add(oResource)

Case 1

'apt.CssClass = "rsCategoryBeige"

'apt.BackColor = Drawing.Color.Beige

'apt.ForeColor = Drawing.Color.Black

oResource = New Resource("Calendar", "cat2", "category 2")

apt.Resources.Add(oResource)

End Select

ok I tried to remove the code front tags and add instead in the page behind

RadScheduler1.ResourceStyles.Add(New ResourceStyleMapping("Calendar", "cat3", "category 3"))

RadScheduler1.ResourceStyles.Add(New ResourceStyleMapping("Calendar", "cat4", "category 4"))

^^ didn't work
I also tried this

RadScheduler1.Resources.Add(New Resource("Calendar", "cat1", "category 1"))

^^ didn't work
highest preference is to add these colorings only in the provider but if I need to I can also add them dynamically in my page vb code if needed.
I use the webservice to keep from doing any database calls in the page to slow down my page. it would help to have the coloring only in the provider (webservice call) also.

Insert a new item by positioning by row index, client-side

I am looking to programmatically insert a new item in the TreeList client-side (javascript). I basically want to create a new item, set the new cell values, its parent, and insert it into the tree at a predetermined position. I found how to do this with the TreeView, but not the TreeList.

troubles reading datatextfield of selected item

Hi,
I have problems retrieving the text of a raddropdownlist.
I populate the ddl in a quite basic way (Articles is a datatable):

ddlArticle.DataSource = Articles;

ddlArticle.DataTextField = "Description";

ddlArticle.DataValueField = "CodArt";

ddlArticle.DataBind();

Changing the selected value triggers nothing.
A button near the ddl triggers some events (basically, a databind on a radgrid); at this time i need to read datatextfield and datavaluefield:

string opv = ddlArticle.SelectedValue;

string articlename = ddlArticle.SelectedItem.Text;

ddlArticle.SelectedValue works perfectly and opv really contains the selected value, but ddlArticle.SelectedItem.Text throws an exception:

Exception thrown: 'System.NullReferenceException' in App_Web_prodotto.aspx.11948b1e.cmqcknjt.dll ("Object reference not set to an instance of an object.")

So i tried another way:

string opv = ddlArticle.SelectedValue;

RadComboBoxItem Item = ddlArticle.FindItemByValue(opv);

string article = Item.Text;

Again, opv contains the correct value, but Item.text is null, and Item is null too.

I am using Telerik 2016.3.

Thank you for any help you can provide.
