I want to do something like what happens at http://demos.telerik.com/aspnet-mvc/treeview/checkboxes, where when you click a node, its parent nodes light up but are not checked. I've looked at the demo and can't figure out how to make this happen. Any ideas would be helpful.

It's the end of the day on Friday, so I don't really have time right now to come up with samples of my code. If no one has an idea by Monday, I will do that.

Thanks!

Hi, after following the guide on setting the colour of tasks on data binding, which worked great, we have noticed an issue. If we have something like the following tree

Level 1

-- Level 2

---- Level 3

---- Level 4

Level 5

Level 6

If level 3 and 4 have a background colour set to say purple.... its working fine, but if we collapse Level 2, Level 5 and 6 have the background colour changed to purple as Level 3 and 4 would have been.

From looking at the source code, Levels 5 and 6 seem to replace the details in the rows for Level 3 and 4 but don't change the styling used. What we need to do is on collapsing the level, we need to repaint the rows to refresh the styling.

Is there any event we can use to detect the expanding / collapsing function so i can call another function which repaints the displayed tasks? I've included 2 screenshots which demonstrate the behaviour.

I have set  a java script method

validatePhone

to be called for customeValidator against any change on a RadMaskedTextBox.  But its never gets called.

Can you please help whats wrong here?

<td>
                <telerik:RadMaskedTextBox ID="sNumberPhoneMasked" runat="server" SelectionOnFocus="CaretToBeginning" 
                    Text='<%# SafeEval(Container, "DataItem.Test") %>' ValidationGroup="PhoneValidationGroup1" ></telerik:RadMaskedTextBox>
                <asp:Label ID="sNumberPhoneMaskedValidationIndicator" runat="server" class="WizardValidationRequired_Person vAdjustment" >*</asp:Label>
                    
                
                <asp:CustomValidator runat="server" ID="sNumberPhoneMaskedValidator" ValidationGroup="PhoneValidationGroup1" ErrorMessage="Phone Number is required."
                             SetFocusOnError="true"   ControlToValidate="sNumberPhoneMasked" ClientValidationFunction="validatePhone"></asp:CustomValidator>
                    <asp:ValidatorCalloutExtender ID="sNumberPhoneMaskedPopupValidator" runat="server" 
        TargetControlID="sNumberPhoneMaskedValidator" Width="200px" />

            </td>
 
<td align="right" colspan="2">
    <asp:Button ID="sPhoneGridEditFormSubmit" CssClass="button-blue" Text='<%# (Container is GridEditFormInsertItem) ? "Add" : "Update" %>'
        runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "Add" : "Update" %>' ValidationGroup="PhoneValidationGroup1"
        CausesValidation="True"></asp:Button>&nbsp;
    <asp:Button ID="sCancel" CssClass="button-blue" Text="Discard" runat="server" CausesValidation="False"
        CommandName="Cancel"></asp:Button>
</td>
 
<script type="text/javascript">
function validatePhone(Source, args) {
    debugger;
    alert('test');
    args.IsValid=false;
    
}
</script>

Hi,

I'm looking for some guidance on the best way to pivot data that is being returned from a .NET MVC controller. I'm able to read it into the regular grid by doing the following :

 @(Html.Kendo().Grid<Project.Models.viewMyModel>()
    .Name("grid")
    .ToolBar(tools => tools.Excel())
    .Columns(columns =>
    {

        columns.Bound(p => p.Field1).Width("auto");
        columns.Bound(p => p.Field2).Width("auto");
        columns.Bound(p => p.Field3).Width("auto");
        columns.Bound(p => p.Field4).Width("auto");

    })
       .Excel(excel => excel
       .FileName("Report1.xlsx")
       .ProxyURL("Report?handler=Save")
       .AllPages(true)
       )
    .Height(550)
    .AutoBind(false)
    .Pageable() 
    .Sortable()
    .Scrollable()
    .Resizable(r => r.Columns(true))
    .Filterable()
    .DataSource(dataSource => dataSource
    .Ajax()
    .Read(read => read.Action("GetSummary", "Reports").Data("getParams"))
    .PageSize(100)
    .ServerOperation(false)
    )
    .Events(ev => ev.ExcelExport("onExcelExport"))
    .NoRecords(n => n.TemplateId("no-records-template-id"))
    )

The form post submits some date parameters to the 'GetSummary' controller and returns the json data source for the grid.

I would like to pivot these results so that Field1 results are my column headers and the other fields are my rows. Would PivotGrid be a good option or is that overkill? If so - I wasn't sure how to get it to read the json results as as I did with the grid above. Or would you suggest I pivot/manipulate the data beforehand and continue to read with the traditional grid method?

Thanks,
Adam

At some point the telerik textbox has become a full widget and it generates a script.

I have a form where I need to have an input and it should look like the telerik textbox. I do not want to use the span / input template I just need to have the input alone.

I know I can define my own styling but I would need just a telerik class on the input that if I change something to be applied to all telerik textboxes.

Hi,

I have this code here inside the form and only code for the switch(), : 

<div class="create-section">
    @(
        Html.Kendo().Form<WeighmoreSouth32Web.Models.Role>()
            .Name("createForm")
            .HtmlAttributes(new { action = "Create", method = "POST" })
            .Validatable(v =>
            {
                v.ValidateOnBlur(true);
                v.ValidationSummary(vs => vs.Enable(true).TemplateId("validation-message"));
            })
            .Items(itemGroup =>
            {
                itemGroup.AddGroup().Layout("grid").Grid(g => g.Cols(3).Gutter(20)).Label("Role Info").Items(items =>
                {
                items.Add()
                .Field(f => f.RoleName)
                .Label(l => l.Text("Role Name"));
                items.Add()
                .Editor(e => e.Switch().Name("AddCustomer")).Field(f => f.AddCustomer)
                .Label(l => l.Text("Role Name*:"));
            });
        })

        )
   

</div>

 it is working fine for the textbox input but when I use switch to pass the true value it is passing it two times one true and other one false. But it does not do the same when switch is off, only passes the false value. Here is a picture of it. I did also tried some Js/Jquery code to bind it but it didn't worked as well. Please help. 

https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/listview/binding/ajax-binding

@(Html.Kendo().ListView<ListViewCore.Models.OrderViewModel>()
          .Name("ListView")
          .TagName("div")
          .ClientTemplateId("template")
          .DataSource(dataSource => dataSource
              .Ajax()
              .PageSize(6)
              .Read(read => read.Action("Orders_Read", "ListView").Data("additionalData"))
          )
          .Pageable()
      )
      <script>
          function additionalData() {
              return {
                  firstName: "John",
                  lastName: "Doe"
              };
          }
      </script>
 
the .Ajax() instantly doenst work. EVERY sample fails !!!
 
Anyone have a listview<T> that actually works? the demos and samples all fail.

Hi people,

I have a little big org chart.

Does anyone have an idea how to optimize the chart ? How to make it more readable ? the free spaces are so big.

Thanks

Is there anyway to use the DropDownTree without it having to make so many requests.

It looks like it is essentially building the tree one request at a time for each item inside it. This is ridiculously inefficient.

Why can't it be passed a single data structure in a request to build itself, after all a dropdownlist,  combobox even a grid can be built with a single request for the IList<data> to databind. 

There is little to no documentation on the DropDownTree control which is disappointing.

For a Data structure like this, it makes 6 request which makes no sense.

• Item 1
  • Item 1A (parent=1)
  • Item 1B (parent=1)
• Item 2
  • Item 2A (parent =2)
• Item 3

Could someone at telerik please provide an example of how to create such a data structure that can be passed to the DropDownTree in one request to allow it to render this. Currently this control is not very usable if it needs one request per item.

A treeview will load all it's data with a single request that returns an

var data = (IList<DataModels>)object .ToTreeDataSourceResult(request, e => e.ID, e => e.Parent_ID, e => e);

Does the DropDownTree not have something similar to a TreeDataSource? Why can't it use the same TreeDataSourceResult Object?
