Line Chart Error

I've got the line chart below on my page and am binding this to a dataset on click of a search button once the user has selected their criteria.

This dataset contains columns Country, Product & Price. I would like Country displayed along the bottom (x-axis), and then have Price plotted on the graph for each product.

I believe I've got this defined correctly however when I run the report I get a js error "'t.options' is null or not an object". Please can you advise on this?

In the code behind I'm simply retrieving my dataset and then:

chartPriceCorridor1.DataSource = Prices;

chartPriceCorridor1.DataBind();

<telerik:RadHtmlChart ID="chartPriceCorridor1" runat="server" Width="600px" Height="400px" Skin="Metro">

<ChartTitle Text="Price Corridor" >

<Appearance Align="Left" />

</ChartTitle>

<Legend>

<Appearance Position="Bottom" />

</Legend>

<PlotArea>

<Series>

<telerik:LineSeries AxisName="Country" Name="Product" DataFieldY="Price"></telerik:LineSeries>

</Series>

</PlotArea>

</telerik:RadHtmlChart>

Can the OnAjaxRequest property of the RadAjaxManager be set programmatically?

It says in the documentation that you can only have 1 RadAjaxManager on a page... I am thinking that I could really use the RadAjaxManager to be multi-purpose! I am currently triggering the ajaxrequest from closing a spawned radwindow) see code below...

//OnClientClose function

function runthisOnWindowClose() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();

}

I was thinking that if I wanted to refresh my parent page from a second spawned radwindow ( on it's onclose event)....I would need to call a different code-behind function from the same RadAjaxManager's onajaxrequest property. So wouldn't it be nice if I could dynamically set the onajaxrequest from the codebehind when using a different popup.

RadGrid Disabled Selection

In the attached image there is a RadGrid with a GridClientSelectColumn with some of the checkboxes disabled.

I would like the 'select all' checkbox at the top, to only select the rows that are enabled, just two rows in this case. I would like the 'select all' checkbox to function as it would normally, but only take into account the two rows that are enabled.

e.g.

. tick the 'select all' checkbox and both enabled rows are selected.

. untick the 'select all' checkbox and both enabled rows are deselected.

. tick the first enabled checkbox and then tick the second enabled checkbox and the 'select all' checkbox at the top becomes ticked and vice versa.

I've tried several different methods but each one has not quite worked, including various server side code and jQuery.

The problem with the most obvious approach is that the 'select all' checkbox at the top will end up ticking all the checkboxes regardless of whether they are enabled or not.

Many thanks in advance

Mike

[Solved] Access GridGroupHeaderItem client-side (javascript)

Is it possible to access the GridGroupHeaderItems client-side? Assuming I have something like this in my grid:

<GroupHeaderTemplate>

<asp:CheckBox runat="server" ID="cbGroupHeader"/>

</GroupHeaderTemplate>

I can do something like this server-side:

foreach(GridGroupHeaderItem item in RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader))

{

var cb = (CheckBox)(item.FindControl("cbGroupHeader"));

cb.Checked = true;

Can I do something like this client-side (i.e., with JavaScript)? All I can seem to get is the data items.

Thanks,

J

Unregistered handler for RadAsyncUpload breaks the File Browser dialogs of RadEditor in Q3 2012

To provide better File Upload experience and usability, starting from Q3 2012, RadAsyncUpload is enabled out-of-the box in RadEditor's File Browser dialogs. Therefore the handler for the AsyncUpload should be registered in the web.config explicitly:

<httpHandlers>

<add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />

<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />

</httpHandlers>

...

<handlers>

<add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" />

<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

</handlers>

If the Telerik.Web.UI.WebResource.axd handler is not registered AsyncUpload will not function correctly and the File Browser (ImageManager, DocumentManager, MediaManager, etc) dialogs will look in a similar way:

Both Telerik.Web.UI.DialogHandler.aspx and Telerik.Web.UI.WebResource.axd handlers can be registered in the web.config file via the RadEditor's smart tag.

[Solved] Radconfirm Problem when using RadButton

Hi,

In my page I have to popup the radconfirm on a button click. Depends upon the value return by radconfirm I have to perform some actions that is if it is false or null then cancel the click event action. If it is true then I donot perform no operation because i have written the server side button click event handling function so it will call. My problem is if i click button radconfirm is popuped and it doesnt wait for the value return by the radconfirm it postbacks and perform the server side action.

I checked the documentation in following tutorial
http://demos.telerik.com/aspnet-ajax/window/examples/confirmserverclicks/defaultcs.aspx,

In this they are using ASP button but I have to use radbutton. Please give a solution for this.

Thanks
Velkumar.

Update RadGrid with Update SQL command

Trying to update RadGrid with the following SQL update command along with this sql select statement. The table I am updating to has 1 column named "Contactnum" which contains contact #'s and a column "Priority" which lists the Priority as 1,2, or 3. In my update statement, I need to know how to add the Contactnum2 & Contactnum3 and the Priority 2 and 3 to the update statement.

DECLARE @ContactNum NVARCHAR(50)

SET @ContactNum = '555-5555 Office'

DECLARE @Priority int

SET @Priority = 1

UPDATE Physician_Contacts

SET ContactNum = @ContactNum

From Physician_Contacts

WHERE Priority = @Priority

SELECT A.Phys_Name, E.Specialty, A.Clinic, A.Office_No, A.Residence_No, A.Fax_no, A.Beeper_note,

b.ContactNum, c.ContactNum as Contactnum2, d.ContactNum as Contactnum3

FROM PhysicianMainList as A

left join Physician_Contacts as B on A.Phys_Staff_ID = B.Phys_Staff_ID and b.priority = 1

left join Physician_Contacts as C on A.Phys_Staff_ID = C.Phys_Staff_ID and c.priority = 2

New Comments feature conflict with Browser Context Menu

In Firefox / Safari / Chrome (all non IE browsers), IF we have the new Comments feature enabled, it will bypass the Browser Context Menus and only show the Commenting feature.

In IE, all RADeditor, and Browser Content Menu's appear. I understand this is not possible to duplicate on Firefox and Safari, but I would still like the ability to correct spelling errors by allowing the default browser context menu for Firefox/Safari/Chrome.

Is there a way we can enable the default browser content menu for the other non IE browser, but still retain the RADEditor context menu for other elements (like right clicking images, tables, links, etc...)?

Grid only partially translated

Hello,

we use the RadGrid and translate it via ressource files. Strangely not all texts are translated, most of the times the header right-click menu (for grouping, hide columns etc.) is translated but the filter strings (contains, between, equal etc.) are not. Those texts are taken from the default ressource file instead. Even more strange: for one of our grid instances those filter texts are translated...

Anything we might be missing?

Regards
Chris
