Enable context menu for some appointments, not for all

I'm using the scheduler with webservice databinding.

Is it possible to enable the context menu for some appointments, but not for all? If so, how could that be accomplished?

Reading Checkbox from ItemDataBound

I have a RadGrid that is bound to a SQL database. On the select statement I generate a column that is not in the table. "SELECT '-' as [CheckBox] ...". I then use the ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) event on the RadGrid to add a column of check boxes (one on each row). The user selects certain check boxes (specifying a row) and presses a submit button. How can I read what rows were selected?

I do not use the information to update the database. The database is used for management and does not change. If I can't read the selection is there a different way to do this? Using a RadGrid is just so nice so I would like to keep using that, but I don't need to bind it to a database.

Thanks,
Scott

Grid events not working as intended

Hello,
I've been working with radgrids lately and they are working very inconsistently for me.
Here is my latest grid:

[CODE] <telerik:RadGrid ID="PermissionsGrid" runat="server" AllowPaging="True" CellSpacing="0" GridLines="None" AutoGenerateColumns="false" OnPageSizeChanged="PermissionsGrid_PageSizeChanged" OnPageIndexChanged="PermissionsGrid_PageIndexChanged" OnNeedDataSource="PermissionsGrid_OnNeedDataSource" EnableLinqExpressions="False" Skin="Tabbed" EnableEmbeddedSkins="False" AllowCustomPaging="True" OnPreRender="PermissionsGrid_PreRender" OnInit="PermissionsGrid_Init"> <ClientSettings> <Selecting AllowRowSelect="false"></Selecting> <Scrolling AllowScroll="True" UseStaticHeaders="true"></Scrolling> <Resizing AllowColumnResize="True" /> </ClientSettings> [/CODE]

However the pageindexchanged event was not fiiring, therefore I added rebind on postback, which then fired onneeddatasource which made the page index changed event fire only then, which was very weird, as well it only worked if i did databind on the radgrid once again (rebind was not working).
Now I am having problem with PageSizeChanged event, was not inteding to put it, but it is not working for me at all. However this time it's neither fiiring even after rebinding on postback and I cant seem to find why.

Init and prerender are only for nestedViewTemplate purposes, therefore there is nothing interesting there.

I am using one of the newer telerik controls (2015.2.623.35)

As well as the pager dissapears even if I set pager style on mastertableview as always visible, on in the grid itself and even in the code, it does not intend to stay even with all this code on its back. I am out of ideas and I need help with this.

Checkbox in header not checking when RenderMode=Mobile

I love the look of the mobile version of radgrid paging so I want to use it regardless if the client is on a desktop. I don't want to use the "auto" render mode.

In the header I have the following Javascript which works correctly if RenderMode=Mobile is NOT set:

<script type="text/javascript">

function CheckAll(checkAllBox, checkboxName, allcheckboxName) {

//var frm = document.form1;

var frm = document.getElementById('form1');

var ChkState = checkAllBox.checked;

for (i = 0; i < frm.length; i++) {

e = frm.elements[i];

if (e.type == 'checkbox' && e.name.indexOf(checkboxName) != -1)

e.checked = ChkState;

}

</script>

A simple radgrid I created on a new webform clean of any of my own javascript and css:

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server"></telerik:RadScriptManager>

<telerik:RadGrid BorderStyle="None" Width="100%" ID="dgrTestGrid" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" GridLines="None" PageSize="20" RenderMode="Mobile" >

<pagerStyle Mode="NextPrevNumericAndAdvanced" />

<MastertableView EnableNoRecordsTemplate="True" >

<Columns>

<telerik:GridTemplateColumn UniqueName="TemplateColumn">

<ItemStyle HorizontalAlign="Center" CssClass="TableBodyLight"></ItemStyle>

<HeaderTemplate>

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

</HeaderTemplate>

<ItemTemplate>

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

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<NoRecordsTemplate>

<div class="NoRecords">You have no Records.</div>

</NoRecordsTemplate>

</MastertableView>

</telerik:RadGrid>

Bind your own data to this and you'll see what I mean. You can't check the checkbox in the header (you can but it doesn't toggle the checkboxes in the rows).

Any suggestions on how to set the pager to be mobile and have the check all functionality (without ajax.. I want it to be client side) other than just recreating the look with a custom pager or going with a simple ASP datagrid (which defeats the purpose of me using Radcontrols in the first place).

Problem with classic RadComboBox V2.8.8 and IE 11 and Umlaut

Hello

As the classic telerik controls are no more supported by telerik I try my luck here...

The problem occurs with a user control that dynamically creates a dialog
using some RadComboBox (version V2.8.8) controls. The problem occurs only when there are
items with umlaut (eg. 'Enhält') in the drop down box.

Is this issue known and is there a workaround for this? As for now we suggest to our customer to use another browser.

Here you find a working project demonstrating the issue with IE 11: http://www.filedropper.com/webcontrols-manualtests
There is also video and a word document showing the result in IE (not working) and firefox (working as expected).

Changing the code to use the latest telerik controls would be also an option, but I didn't manage to convert the code.

Hope someone can help!

Regards,
Tonino.

Set a value while load on demand by web service

Hi!

I'm using multiple RadComboBoxes that are filled by a web service like this:

1.<telerik:RadComboBox runat="server" ID="Value" Width="300px" EnableLoadOnDemand="true" OnClientItemsRequesting="LookupItemRequesting" OnItemsRequested="Value_OnItemsRequested" AutoPostBack="False">

2. <WebServiceSettings Path="/Handlers/IdmpService.asmx" Method="LoadDropDownValues" UseHttpGet="true"></WebServiceSettings>

3.</telerik:RadComboBox>

The method to fill the combobox looks like this:

01.[WebMethod(true)]

02.[ScriptMethod(UseHttpGet = true)]

03.public RadComboBoxData LoadDropDownValues(RadComboBoxContext context)

04.{

05. var res = new RadComboBoxData();

06. var itemType = context["ItemType"].AsString();

07. var valueProperty = context["ValueProperty"].AsString();

08. ...

09. var result = new List<RadComboBoxItemData>();

10. try

11. {

12. ...

13. foreach (Dictionary<string, object> item in items)

14. {

15. // process items...

16. result.Add(new RadComboBoxItemData { Value = "some integer id", Text = string.Join(", ", string.Format(displayFormat, values.ToArray())) });

17. }

18. }

19. catch (Exception ex)

20. {

21. result = new List<RadComboBoxItemData> { new RadComboBoxItemData { Value = "", Text = ex.Message } };

22. }

23. res.Items = result.ToArray();

24. return res;

25.}

Together with quite a few other Telerik controls this is a form used to view/edit data, so I need to set a specific value for thie ComboBox. How can I assign a value to the ComboBox to make sure that when I save the whole data, I can read the correct value from the ComboBox?

Thanks!

How to maximize the radwindow

Hi,
I added some custom tools in my radEditor and I open the RadWindow with this code :

Telerik.Web.UI.Editor.CommandList["InsertDoc"] = function (commandName, editor, args)

{

var myCallbackFunction = function (sender, args)

{

alert("Hello World");

}

editor.showExternalDialog

(

'/Test.aspx',

{},

950,

700,

myCallbackFunction,

null,

'Insert Document',

true,

Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Move,

false,

true

);

};

It works fine but now, I would like to maximize the RadWindow like with this code

var manager = $find("<%= RadWindowManager1.ClientID %>");

var oWin = manager.open("Test.aspx", "RadWindow1");

oWin.maximize();

How can I do that ??

Thanks.
