[Solved] Issue with displaying date (from x axis) in tooltip

Hi everyone,

I am using a RadHtmlChart to display some data amount. I display the amount of
all items (as area series) and the new items per day (as column series) on one
timeline. Therefore I use a data table with a date column (type is
System.DateTime), an absolute value column (type is System.Int32) and a per day
value column (type is System.Int32). On page load all data is displayed. There
are two date time pickers (RadDatePicker) to change the displayed time range.
The change of the time range is done on client site. Therefore I take the
original dataset, store it (for later changing back to another time range) and
creating a new data source with all elements in the selected time range. After
the data source is build I bound it to the chart and repaint it. This
works perfectly, but I face a strange
issue with the tooltips. In the tooltips I want to display the date of the
hovered item (this seems to work. I´ve done this as shown in your demo).
Everything seems to work perfectly until I choose a time range containing only
two entries and there date values are not in the same month. The values are
shown correctly in the chart and the JSON string behind (gotten with
chart.get_dataSourceJSON ()) looks correct to me, but the displayed date in
the tooltip is not the correct one.

Could you give me a hint what’s going wrong with my tooltips? Any help would be
appreciated.

The error occurs if you select time range from 15.05.2014 to 10.06.2014 or
16.06.2014 to 05.07.2014.

If you choose another range where one more item is displayed the error
disappears. Also ther is no issue if
you select a time range containing just two elements but in the same month.
Here is the code I use for this lightweight version. If the project is needed i can send it to you

new to radeditor and export to pdf

I am just starting to work with a C#.net 2010 web form application, where I need to make small changes. I have never worked with the RadEditor before. I am getting the following error message when I run the application listed below.

My questions are the following:
1. Where can I obtain a copy of the Radeditor so That I can work with it? My company has a license for teletrik?
2. Once I have the radedior installed, can you tell me how to use it so that I can find the error that is being referred to below?
3. Will using a regular html editor be good enough?

[Exception: Invalid XHTML. RadEditor content should be correct XHTML in order to export to PDF.

Get count of selected child rows in hierarchical grid in JavaScript

Hi guys,

I am using RadGrid in RadControls for ASPNET AJAX Q2 2008. How do I get a count of all selected rows in the child grids on the clientside (JavaScript). Please note that I am using Q2 2008 RadGrid. The examples I have seen on this site and elsewhere work for newer versions of the RadGrid but they don't work on the Q2 2008 version. Kindly assist. See attachment for the sample of what my grid looks like.

Thanks,

Class added to Node does not persist after postback

I have two RadTreeViews and am using these to create a data picker... so Available nodes on the left treeView... User Selected nodes on the right treeView...

After the user has selected a node and moved it to the right treeView, I would like to style the nodes as follows:

SelectedNode : Bold [Node Enabled]
ParentNode: Grey [Node Disabled & Node Expanded]
ChildNodes: Normal font [Node Disabled]

I use javascript to achieve this, which works fine the first time round using the 'window.onload' event.

Issue: When I postback the page... all settings remain in place (eg - enabled/disabled) but the styles do not.

I use the trackChanges() and commitChanges() around my javascript code.

I am using the following to remove classes
$telerik.$(node.get_element()).removeClass('bold');

I am using the following to add classes:
$telerik.$(node.get_element()).addClass('bold'); - Does not persist

I am using the following to enable / disable nodes
node.set_enabled(true); - Persists fine...

Can anyone advise why the settings persist but the css styles do not?

Thanks

RadGrid ignoring 'GroupHeaderItemStyle-ForeColor' Attribute

Hi,

I have a RadGrid on one of my ASP pages and I want to change the text color on the group header to something more readable. The default value is quite unreadable, as in the attached example1. I have set the 'GroupHeaderItemStyle-ForeColor="White"'-attribute, but it seems that it is simply ignored at run time. If I set the 'GroupHeaderItemStyle-Font-Bold="true"'-attribute, it is successfully picked up. I have tried setting the 'GroupHeaderItemStyle-CssClass'-attribute to a relevant value as well, but had no success with this as well.

How would I go about achieving this?

The second question I have is how to remove the header columns in the grid for the nested groups as in example 2? I wish to achieve a similar look to the grid in the Telerik example at: http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/grouping/grouping/defaultcs.aspx

Thanks for the assistance!
Regards.

trying to understand no license file licensing

I'm on a team that has one license for DevCraft UI Edition and I don't feel like I'm understanding licensing well enough. I've been reading this:
http://www.telerik.com/help/aspnet-ajax/introduction-deploying-on-shared-hosting.html

And I have the following paragraph that I think is key from the purchase confirmation email that went to the developer on my team that we purchased the license thru:
Note: The controls
come with a special build, which does not have domain or server deployment
limitations and can be used in an unlimited number of projects. That same
developer build works without license keys and never throws license key errors.
******************************************************************************************************

I'm not used to this type of licensing so I'd like to confirm: We can install the product on any number of our developer laptops -- the licensed version that we can download from Telerik or did already, deploy to as many servers as we want and all the laptops and servers will not ever display the "unlicensed version" overlay that happens with unlicensed versions.
