Is it possible to get all Theme names from SkinManager?

Is there a way in code behind to pull all possible Theme names from the Skin Manager into a string array?
I was thinking it might be stored in RadSkinManager.Skins but I didnt find it there. If it is possible please
show code example.

Thanks,

SkinManager

Recurrence Rule / Occurrence Count IEnumerable Error

Hello,

I am having a problem referencing any of the iEnumerable properties on Occurrences collection for the RecurrenceRule class. It is working OK in one project (4.0 framework) but I am having compilation errors in the other project such as:

Error 179 'Count' is not a member of 'System.Collections.Generic.IEnumerable(Of Date)'.

The above error is happening with this code:

If parsedRule.Occurrences.Count > 0 Then

In my other project the above works OK. I've tried adding references to different framework system libraries but it doesn't seem to make any difference.

Any idea why the above would be happening? Am I missing a reference or do I need to change a reference? I am using the Q3 2014 UI AJAX ASP.NET controls.

Paging lost while bind RadGrid clientside

Hello Team,

I have created a radgrid from Cs as per the wbelow code:

RadGrid radGridNew = new RadGrid();

radGridNew.ID = "rgAcc" + Guid.NewGuid().ToString().Replace("-", "");

radGridNew.ClientSettings.ClientEvents.OnGridCreated = "GridCreated";

radGridNew.ClientSettings.ClientEvents.OnCommand = "RadGrid1_Command";

radGridNew.AllowPaging = true;

radGridNew.PageSize = 10;

GridBoundColumn colLogDate = new GridBoundColumn();

colLogDate.DataField = "LogDate";

colLogDate.UniqueName = "LogDate";

colLogDate.DataType = typeof(DateTime);

colLogDate.HeaderText = "Log date";

GridBoundColumn colIPAddress = new GridBoundColumn();

colIPAddress.DataField = "IPAddress";

colIPAddress.UniqueName = "IPAddress";

colIPAddress.DataType = typeof(string);

colIPAddress.HeaderText = "IP Address ";

GridBoundColumn colResult = new GridBoundColumn();

colResult.DataField = "Result";

colResult.UniqueName = "Result";

colResult.DataType = typeof(string);

colResult.HeaderText = "Result";

radGridNew.Columns.Add(colLogDate);

radGridNew.Columns.Add(colIPAddress);

radGridNew.Columns.Add(colResult);

radGridNew.AllowSorting = true;

radGridNew.MasterTableView.AllowMultiColumnSorting = true;

radGridNew.ShowFooter = true;

radGridNew.AutoGenerateColumns = false;

radGridNew.MasterTableView.PagerStyle.AlwaysVisible = true;

radAcc.Controls.Add(radGridNew);

On Grid Created Event We have called a page that gives data in Json Object as below:

function GridCreated(sender, eventArgs) {

var Id = sender.ClientID;

$.ajax({

type: "GET",

url: "LoadWidgetsAsync.aspx",

contentType: "application/json; charset=utf-8",

data: { Wid: 1, widgetName: "AccountActivityWidget", ID: Id },

async: true,

success:

function (result) {

if (result.length > 0) {

var grid = $find(result[0]);

var tableView = grid.get_masterTableView();

tableView.set_dataSource(result[1]);

tableView.dataBind();

}

},

error: function () {

alert('Error on binding the data');

}

});

}

Once it bind the data to grid, It seems all data in one page rather then displaying only data of first page defined in page size.

Can anyone help me out with this?

Thanks and regards,
Ruchi Patel

RadAsyncUpload - OnClientFileUploading

Hi Telerik,

is "set_cancel" method still supporting OnClientFileUploading(http://www.telerik.com/help/aspnet-ajax/asyncupload-onclientfileuploading.html)?

I tried to use args.set_cancel(true) but got a javascript exception - Microsoft JScript runtime error: Object doesn't support property or method 'set_cancel'

Below is my code:

Javascript:
function OnClientFileUploading(sender, eventArgs) {

//cancel the upload

eventArgs.set_cancel(

true);

alert(

'no duplicate file: ' + args.get_fileName());

//hide the uploading item

$telerik.$(eventArgs.get_row()).css(

"display", "none");

}

HTML:

<

telerik:radasyncupload id="Radasyncupload1" runat="server"

OnClientFileUploading="OnClientFileUploading"

>

</telerik:radasyncupload>

[Solved] Paste image with Internet Explorer

Hi, I have trouble getting the image-paste-feature (inlined base64 data) of the RadEditor to work in Internet Explorer.

I see in the demo, that it actually works (IE11):
http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

However, when I use the demo code locally, it works in Firefox, but not in IE... I'm sure I forgot something (e.g.: is there a certain script I miss? I referenced only the DLLs).

ASPX code (no codebehind code)

radGantt problems with insert and delete

I am trying to implement radGantt per some of the demos, as it looks to be a very nice control indeed. Obviously it works ok on the demo page here : http://demos.telerik.com/aspnet-ajax/gantt/examples/overview/defaultvb.aspx

I would copy this page directly, and try and get it working, however Telerik.Web.SessionDS cannot be found, hence the tag can't be registered, and the page doesn't work. I am using the latest build, 2015.1.225.45. That's problem one.

Now at one point, I had insert working, which has subsequently stopped during some of the cobbling together of different demos. Current asp code is as follows :

<div class="demo-container no-bg">
        <rad:RadGantt ID="RadGantt1"
            runat="server"
            DataSourceID="SqlDataSource1"
            DependenciesDataSourceID="SqlDataSource2"
            ReadOnly="false"
            SelectedView="WeekView" AutoGenerateColumns="false" >
            <Columns>
                <rad:GanttBoundColumn DataField="Title" DataType="String" Width="120px"></rad:GanttBoundColumn>
                <rad:GanttBoundColumn DataField="Start" DataType="DateTime" DataFormatString="dd/MM/yy" Width="40px"></rad:GanttBoundColumn>
                <rad:GanttBoundColumn DataField="End" DataType="DateTime" DataFormatString="dd/MM/yy" Width="40px"></rad:GanttBoundColumn>
            </Columns>

            <DataBindings>
                <TasksDataBindings
                    IdField="ID" ParentIdField="ParentID"
                    StartField="Start" EndField="End"
                    OrderIdField="OrderID"
                    SummaryField="Summary"
                    TitleField="Title" PercentCompleteField="PercentComplete" />
                <DependenciesDataBindings
                    TypeField="Type" IdField="ID"
                    PredecessorIdField="PredecessorID"
                    SuccessorIdField="SuccessorID" />
            </DataBindings>
        </rad:RadGantt>
    </div>

    <asp:SqlDataSource runat="server" ID="SqlDataSource1"
        DeleteCommand="DELETE FROM [GanttTasks] WHERE [ID] = @ID"
        InsertCommand="INSERT INTO [GanttTasks] ([ParentID], [OrderID], [Title], [Start], [End], [PercentComplete], [Expanded], [Summary]) VALUES (@ParentID, @OrderID, @Title, @Start, @End, @PercentComplete, @Expanded, @Summary)"
        SelectCommand="SELECT * FROM [GanttTasks]"
        UpdateCommand="UPDATE [GanttTasks] SET [Title] = @Title WHERE [ID] = @ID"
        />
    <asp:SqlDataSource runat="server" ID="SqlDataSource2" SelectCommand="SELECT * FROM [GanttDependencies]" />

There is a radScriptManager and a radWindowManager out in the master page, with default settings.

At the moment, insert does the postback, but does nothing in the database.

If I try an update, whether double clicking the task on the left hand pane, or the right hand pane, on save I just get the spinning ajax icon. Normally I would expect there to be something amiss with the UPDATE statement causing an an error during the postback, but in this case the update occurs and you can see the results in the database directly. If you refresh the page you see the update reflected in the Gantt chart.

What's additionally frustrating is that when I am trying to use the developer tools to see what's going on in the response headers, I suspect Kendo is getting in the way and it reports script timeout errors. This doesn't occur if I have the dev console off.

What would really help is a demo ( preferably not in C# ) where I can take care of CRUD directly and get at the values in the Gantt control myself. I saw one posted using LINQ but I really don't want to go down that route, I want to stick with our typical environment of parameters/stored procedure calls.

Aside from that, a very useful feature for AJAX enabled controls would be to be able to turn AJAX off, and force a full postback so any background errors can be hunted down more easily.

Thanks in advance,

Gantt
