Hello, I am currently evaluating the Telerik control sets for use in a large project to start soon.  I have a requirement where we will be building a treeview in our ASP.NET MVC controller code using TreeViewItemModel list and passing to the view.  In the view razor code and/or javascript, is there a way to access the TreeViewItemModel as a user is selecting different nodes in the tree?  Specifically, when building the TreeViewItemModel, I populate the .Text and .Id properties and I need to access these values to post back to my controller code to handle the selection changes.  Is this possible? I need to quickly mock something up to demonstrate this.

Controller code to build the treeview contents is here:

public List<TreeViewItemModel> BuildTreeContents()
{
List<TreeViewItemModel> tree = new List<TreeViewItemModel>();
IQueryable<SupplierModel> suppliers = GetSuppliers();
IQueryable<ManagedOrgModel> managedOrgs = null;
IQueryable<ManagedLocationModel> locations = null;
TreeViewItemModel node = null;
List<TreeViewItemModel> orgs = null;
List<TreeViewItemModel> locs = null;
foreach (SupplierModel supplier in suppliers)
{
node = new TreeViewItemModel();
node.Text = supplier.SupplierName;
node.Id = supplier.SupplierID;
managedOrgs = GetManagedOrgs(supplier.ClientID, supplier.SupplierID);
orgs = new List<TreeViewItemModel>();
foreach (ManagedOrgModel managedOrg in managedOrgs)
{
TreeViewItemModel orgNode = new TreeViewItemModel();
orgNode.Text = managedOrg.ManagedOrgName;
orgNode.Id = managedOrg.ManagedOrgID;
locations = GetLocations(managedOrg.ClientID, managedOrg.SupplierID, managedOrg.ManagedOrgID);
locs = new List<TreeViewItemModel>();
foreach (ManagedLocationModel location in locations)
{
TreeViewItemModel locationNode = new TreeViewItemModel();
locationNode.Text = location.ManagedLocationName;
locationNode.Id = location.ManagedLocationID;
locs.Add(locationNode);
}
orgNode.Items = locs;
orgNode.HasChildren = true;
orgs.Add(orgNode);
}
node.Items = orgs;
node.HasChildren = true;
tree.Add(node);
}
return tree;

Thanks,

Hello support,

I am using a MultiColumnComboBox widget in this way

So far so good.

The question is: How can I specify the width of the whole dropdown list and in case the sum of the width of each column is greater than the width of the whole dropdown list then show a horizontal scroll bar (like the grid widget does) ?

Attached is a screenshot of the current widget rendered and below it the scrollbar I want to show (if necessary)

Thank you.

PD: I’ve tried with this post but it didn’t work https://www.telerik.com/forums/dropdownlist-should-take-size-of-biggest-option

I need to display a confirmation dialog on the screen using kendo.confirm. Everything work as expected until I resized the browser to see if the message displays correctly on the mobile. However the confirmation dialog text did not wrap on the screen. I tried to reproduce this in a dojo but can not. After further investigation I found that my site is missing the "display: block" or "display: inline-block" from the window wrapper.

Could you tell me who adds this so I can try to debug and see why the "display" property is not added.

Would someone be able to provide a code snippet of how to programmatically select a row in the Kendo MVC Grid? 

We have the value for the ID (a column in the Grid) in a javascript variable.  We want to display the matching row in our grid and mark it as selected.  I saw the Kendo demos on how to select the row using grid.select(n), where n is the index into the row on the page.  But the demo example doesn't solve this problem.

Note, my data contains several thousand rows and my pageSize is limited to 10 rows per page.

@(Html.Kendo().Grid<ReportViewer.Models.EntityModels.tblTreeView>()
   .Name("grid")
   .Columns(columns =>
   {
     columns.Bound(c => c.Name).Title("Report Name");
     columns.Bound(c => c.Path).Title("Path");
     columns.Bound(c => c.Id).Title(string.Empty).Width("200px");
   })
   .Pageable(pageable => pageable.Refresh(true).PageSizes(true).ButtonCount(3))
   .Selectable()
   .Events(e => e.Change("showInTree"))
   .Sortable(sortable => { sortable.SortMode(GridSortMode.SingleColumn); })
   .DataSource(dataSource => dataSource
   .Ajax()
   .Model(model => model.Id(p => p.Id))
   .Sort(sort => sort.Add("Name").Ascending())
   .PageSize(10)
   .Read(read => read.Action("ReportsGridRead", "Home"))
)
)

Any help is greatly appreciated.

As the title states, is it possible to submit multiple partial views with a single button? Open to using javascript, jquery, ajax. 

I have them coming from the same model, but there are two partial views with separate forms, I am wondering if there is anyway to submit it with just using a single click?

Thanks

Hi All,

I have a grid inside a partialview of index view in a MVC project. I add a context menu to the grid. This menu has 4 items.  Which item(s) will show up depends on how many rows of grid are selected. I assign id to each menu item and tried to use hide() and show() to show certain menu item(s) but it doesn't work.  Anyone know how to do that?

Thanks.

I use a gridview with inline editing, when i Update a double value with 

This is the grid :

This is my View Model:

This is my EditorTemplate "Poids"

This is what i receive when I post modification with decimals (see Attachement).

Additionnals info :

• Kendo 2018.3.911.545 
• Culture is set to fr-FR in web.config solution

Do you have an idea to fix this issue of null value ?

Thank you, 

Julien

I have been trying for several days to bend the menu to my will, and nothing has worked.

I'm using MVC5, Bootstrap 3, and Telerik UI for MVC (2019.1).

I have a div that is 28px tall, and I'm trying to get the menu to be constrained within that div's height. The problem is that the menu appears to be padded/margined and is 50px tall, regardless of the class styles I've tried to set. There doesn't appear to be any documentation (that I've found) that describes how to re-style the components.

For instance, it would be real nice if I could find a description regarding what to do to change the colors, the sizes, and the positioning. What css classes affect each widget?

Hi!

I'm getting all red squigglies on my CSHTML files but the site is still working without compile-time or runtime errors. I'm getting this warning on CSHTML that has Kendo() used on them:

Warning CS1702

Assuming assembly reference 'System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' used by 'Kendo.Mvc' matches identity 'System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' of 'System.Web.Mvc', you may need to supply runtime policy

Also, maybe not related, but all kendo control is not rendering properly at all: Attached

Here is my Web.Config:

As per chrome's Network tab in dev-mode, there is no missing file and no errors on the console tab either.
