I have a treeview which currently shows a hierarchy of items that are different at each level.  The TreeView is configured to use checkboxes and to check the children whenever the parent is checked.  An example (without checkboxes) of the item types is illustrated as follows:

TypeA
    TypeB
    TypeB
    TypeB
        TypeC
        TypeC
    TypeB
TypeA
    TypeB

Since the items vary by level, I want to write some javascript that retrieves the corresponding values by level.  That is, I want to retrieve the values of all checked items at level 1, or all checked items at level 2, or all checked items for level 3.  That said, I modified the code, provided by the example at: http://www.telerik.com/blogs/how-to-get-the-checked-items-from-a-treeview-with-checkboxes which recursively loops through all nodes in the treeview.  Basically, the code examines each node and evaluates the 'checked' property to determine if the node has been checked.  Unfortunately, the 'checked' property is undefined when only a subset of the descendants are checked.  It would be nice if the node had a property indicating that at least one descendant was checked.  I know that I can examine the 'hasChildren' property and recursively loop to determine if any descendant is checked, but I'm hoping that someone has a better approach.  In lieu of a simple property, what is the most efficient way to determine if a node has any 'checked' descendants? 

Thanks.

I am just starting to learn the MVC charts, and I am having a problem with the x-axis labels.  I have not found the right setting to correct it.  I have a line chart that may or may not go below zero on the Y-axis.  The date labels are showing under $0, where they should always be at the bottom of the chart.

Here is the view:

@(Html.Kendo().Chart<tpe2.db.CFForecastData>()
.Name("chart")
.Title("Weekly Cash Flow")
.Legend(legend => legend.Position(ChartLegendPosition.Bottom))
.Tooltip(tooltip => tooltip.Visible(true))
.DataSource(ds => ds.Read(read => read.Action("CFForecastData_Read", "Chart")))
.Series(series => {
series.Line(a => a.CashBalance).Name("Cash Balance").Color("Blue").Markers(false);
series.Line(a => a.RequiredBalance).Name("Required Balance").Color("Yellow").Markers(false);
series.Line(a => a.ZeroLine).Name("Zero").Color("Red").Markers(false);
series.Line(a => a.Receipts).Name("Receipts").Color("Green").Markers(false);
series.Line(a => a.Disbursements).Name("Disbursements").Color("Black").Markers(false);
})
.CategoryAxis(axis => axis
.Categories(model => model.ReportDate)
//.AxisCrossingValue(-200000)
)
.Pannable(pannable => pannable
.Lock(ChartAxisLock.Y)
)
.Zoomable(zoomable => zoomable
.Mousewheel(mousewheel => mousewheel.Lock(ChartAxisLock.Y))
.Selection(selection => selection.Lock(ChartAxisLock.Y))
)
)

Thanks!

I found multiple examples where Master/Detail is nested in the Master Grid using hierarchy.  I wanted to have two separate grids.  I am using Telerik ASP.NET MVC 6 which uses Kendo UI MVC Grid.  Do you have example code to implement this?

Thanks

I have a inline grid and 'sumBudgetAmount' value in a page. When user clicks edit and updates 'IncreaseByAmt' in the grid, I have to check the sum of all the records of 'IncreaseByAmt' in the grid and see it is not greater than 'sumBudgetAmount' value. I want to do client side validation on gridsave event.

I can not do server side validation as I am not updating to the database when user clicks update button. It is a batch editing where user clicks save and then I am saving all the values to the database. So I can use only client side validation.

Thanks,

I have a bar chart (see attached), that I would like to display only the top 10 categories in order by alarm count.  I cannot see a way to only display top N number of categories. This this possible with the bar chart? 

Here is the code.

Hi,

 We use a framework that wrap every ajax response. Instead to have this :

 the response from controller method are :

I would like to use a javascript function so that  can manipulate the ajax response and extract the data before passing it to the Grid.

Is there a way to achieve that? Thank you.

I'm trying to create a string using the text values in the multi select list using Jquery but I'm having trouble trying to get the selected value's text fields.

I can see that theres a value function which returns the ID's of the list (i.e. DataValueField?) but not the text fields (i.e. DataTextField?).

I've had a look at the datasource to see if i can iterate through that instead and find the text values that i need but as im virtualising the multi select list, im only getting a limited subset of the items i need.

Is there any way to get the selected items using Jquery? It seems like such an easy task to do as the objects are already displayed on screen but i cannot figure out how to access them.

Thanks

Hi

I am working through some Telerik sample code and having some errors. I am trying to understand how it works in order to troubleshoot the problem.

Specifically, I am using a ComboBox widget with an id value (let's call it comboID) which is set in the .Name property.

 Now this code from the sample:

$(comboID).each(function () {

eval($(this).children("script").last().html());

});

I think adds a new combo box. What does the ("script") keyword signify?

Now I need to find the ComboBox and update the selected item. 


$(comboID).data().kendoComboBox.value(status);

But get undefined for the kendoComboBox. I'm not sure what this line does. I assume we are looking into the DOM but what is the type that is returned?

Thanks for your help. Just trying to understand.

I have a dropdown inside a grid which currently takes 100% width of the column. Because of number of columns, width of this column is very less compared to the length of each item I have for the dropdown.

I want to make the options list of the dropdown to display full text in single line with out increasing the width of the column. I am using white-space:nowrap to get the text in online but the options list gets  scroll bar. Is there a way that I can increase its width to 100%?
