The back color of appointments loses after cancelling edit the appointments

Hi There,

I am working on the timeline view of the Scheduler. I set the back color for appointments in RadScheduler1_AppointmentDataBound function. But the back color of the appointments loses after clicking the cancel button on the advanced pop-up form. Please see the following for my test code. Any help is much appreciated.

RadGrid W3C validation error

We have seen validation errors (we used W3C validator at https://validator.w3.org/) that are related to colspan being set to number that is less than the number of col elements defined in colgroup. Example:

We have seen these errors in your RadGrid demo source too (http://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx)

When can we expect this issue to be resolved?

Thank you.

Exception with Telerik.Web.UI.WebResource.axd?_TSM_HiddentField_=

Hi,

In my project, I always have exception with the WebResource.axd. For example:

Exception was thrown at line 4596, column 6 in http://localhost:49573/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:fr-FR:c9cbdec3-c810-4e87-846c-fb25a7c08002:ea597d4b:b25378d2;Telerik.Web.UI:fr-FR:df833b2e-28ee-45e7-8320-6f2a9cb883d7:16e4e7cd:f7645509:22a6274a:ed16cbdc:874f8ea2:24ee1bba:f46195d3:19620875:490a9d4e:bd8f85e4

And error in script is line:

{var f=this

._iframe.contentWindow.document.title;

So, as my project is huge, I reproduce it in a simple application:
I had a webpage with a RadWindow. Exception occur (javascript exception).
I had another webpage using a masterpage. This time, RadWindows even do not open!

I think it's a configuration pb but I'm unable to find it.

RadRating: Show selected item on another page

Hi

I am using the RadRating list control. Once the user has entered there data - I would like to show what they have chosen on the next page. The value they have chosen is storing just fine. But when they are on the next page I want to show the rating they choose. I thought the RadRating1.SelectedItem.Value might do the trick but this does not set the item that has been selected.

Any ideas how I show the item they selected on another page - but using the same RadRating control

Thanks in advance

Telerik Rad Grid is not able to access ClientID.

Hi,

I have telerik Rad Grid Control. I want disabled row to be checked even if someone check/uncheck select all functionality. So I have written below Jquery code to handle it.

$(document).ready(function () {
        $("#SelectColumnSelectCheckBox").click(function () {
            var checked = this.checked;
            if (checked == false) {
                $("#ctl00_MainContent_gridRules_ctl00 tbody tr").each(function () {
                    if ($(this).attr('disabled') == "disabled") {
                        $(this).find("input").attr('checked', 'checked');
                    }
                });
            }
        });
    });

I want to change the hardcoded value of grid (ctl00_MainContent_gridRules_ctl00) and Select all checkbox (SelectColumnSelectCheckBox) to clientID.

I have tried <%=Radgrid.ClientID%> but that does not work.

Does anyone know how to get the clientID of the telerik RAD grid?

Please give me reply sooner as this is urgent for me.

Thanks in advance.

Regards,
Devendra.

How let user rename node client-side

Hi,

I have a "Rneame" context menu on my treeview that gets handled client-side and initiates node.startEdit(); The node goes into edit mode & the user can edit the text and hit enter and all looks fine on-screen.

The problem come during postback though - the node in code-behind still has the old name?

function tvwListData_ClientContextMenuItemClick(sender, args) {

var tree = $find("<%= tvwListData.ClientID %>");

var node = args.get_node();

tree.trackChanges();

var item = args.get_menuItem();

switch (item.get_value()) {

case "Rename":

node.startEdit();

break;

case "Delete":

node.get_parent().get_nodes().remove(node);

break;

}

tree.commitChanges();

}

[Solved] Get clientside RadGrid inside RadGrid Edit Form

Hi,

I have a RadGrid inside the EditForm of the main RadGrid:

<telerik:RadGrid runat="server" ID="RadGrid1">

<EditFormSettings EditFormType="Template">

<FormTemplate>

<div>

<asp:Panel runat="server" ID="Panel1">

<table><tr><td>

<telerik:RadGrid runat="server" ID="InnerRadGrid"></telerik:RadGrid>

</td></tr></table>

</asp:Panel>

</div>

</FormTemplate>

</EditFormSettings>

</telerik:RadGrid>

How can I reach via javascript the InnerRadGrid?

I tried using

RadGrid1.Controls.Add(new LiteralControl("<script type='text/javascript'>window['InnerRadGrid'] = '" + InnerRadGrid.ClientID + "';</script>"));

var grid = document.getElementById(window['InnerRadGrid']);

in RadGrid1_ItemCreated() but id doesn't work.

I need it because in the header of some TemplateColumn in the InnerRadGrid I have a checkbox which, when toggled, shoul select/deselect every checkbox in that column. If there is another way to reach this functionality, it'd be fine.

Thank you, regards

Nick

[Solved] Hyperlink Manager URL Encoding issue

On the Telerik site, hyperlinks are not encoded when saving the link in Linkmanager, see screenshot #1.

In our application the %20 are once more encoded to %2520 when OK-ing the Linkmanager, see screenshot #2.

All ContentFiltering is set Standard, just like the demo site...I am using EditorDialogs/LinkManager.ascx though.
