I have a grid with several foreign key columns which display combo-box editor templates. The user enters and selects an item, which sets the id on that column for that record in the grid.

If the user unfocuses the cell without selecting an option, the built-in validation message (shown in the attached screenshot) 'X must be a number' appears. This occurs when the input does not load any data (i.e. they type a name that doesn't exist in the database and so auto-complete doesn't find anything). It seems the validation skips the 'required' message and goes to this invalid-type message. We would like to change or bypass this so that the user doesn't see this user-unfriendly message.

Is there a way to (1) somehow force the combo-box to select an option when losing focus in this case where there was no valid auto-complete option (since normally it does auto-select said option), or (2) to somehow override this error message?

When you hover over the legend it displays all the points for the series you are hovering over.  See attached image.  Is there a way to turn this off?

 

In our application we want the filter on a date column to prompt the user for a start date and an end date, with the filter returning rows where the field in question falls between (or on) those two dates.

Initial Approach

Our initial approach was to restrict date types to use gte and lte operators, and add the "extra : true" filterable option on the column. This came close, but presented the following problems: A) Each date input could use either the gte (Start) or lte (End) operator, providing undesired flexibility and the option for the user to create a filter that would never return results, and B) Presented a logical comparison (And / Or) that we don't want.

Better Approach

A better approach was found on this StackOverflow question. This question has an answer by Matthew Erwin that gets us very close: it allows us to completely re-style the filter entirely, so we can present simply a Start Date input and an End date input. However, what I can't get working is associating the right filter operation with the right input (gte for the Start date, lte for the End date). My custom filter is as follows:


With this approach, the Odata filter option is generated for each of the dates, however it uses the eq Equal To operator, so no values are ever returned. We aren't building filters specifically on the data source.Is there a simple way I can associate each of those date inputs with a specific filter operator? Is there a better way to approach this subject? It seems like filtering dates based on a Start - End range would be commonly desired.

Other Details

We are using AngularJS, and WebAPI with Odata.

Hi,

I have an editor grid that has one editable cell. I want that cell to always be the input box (numeric text box in this case) instead of going back to a regular dirty cell after clicking out. So basically always keeping cells in edit mode.How can I achieve this? See attached image for example of what I mean.

 

I'm using a Kendo Editor in TextArea mode, is there a way I can configure the styles (font, size, color) it applies to the content by default?

Hi,

We have a grid with a detail template containing a tabstrip - much like the demo at https://demos.telerik.com/aspnet-mvc/grid/detailtemplate .

Three tabs got their content from calling controller actions which returned different Partial views.

We do not need to show multiple tabs now - we only need to show one so do not need the tabstrip control.

How can we keep the same method of getting the detailtemplate content from a controller action partialview without the tab strip?

The data is a single model - not a listing - so not suited to a grid or listview.

Many Thanks.

Hi all,

I am trying to make an HtmlHelper to create sub grids by passing an ISubGridBuilder which will contain the construction detail of my sub grid.

Example:

The problem is that at runtime I get a reference error:

How can I add the ParentId parameter on the routeValues for the controller call.

Thank you!

Hello,

We have an MVC project that uses the Kendo MVC grid to return well data records.  Because we use paging and can return several thousand records, we're using Ajax with server side paging like this (abbreviated):

@(Html.Kendo().Grid<GroundWater.Models.GroundWaterSearchResult>()
          .Name("grid")
          .Columns(columns =>
          {
              columns.Bound(p => p.well_id).Title("Well ID").Width(75).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Well_Name).Title("Well Name").Width(105).Locked(true);
              columns.Bound(p => p.Permit).Title("PermitNo").Width(90);
              columns.Bound(p => p.Well_Depth).Title("Well Depth").Width(64).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Water_Level_Depth).Title("Water Level Depth").Width(66).Format("{0:n2}").HtmlAttributes(new { style = "text-align: right;" });
               columns.Bound(p => p.Measurement_By).Title("Measurement By").Width(111);
              columns.Bound(p => p.publication_name).Title("Publication Name").Width(93);
              columns.Bound(p => p.Elevation).Title("Elevation").Width(78).Format("{0:n2}").HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Elevation_Accuracy).Title("Elevation Accuracy").Width(121);
              columns.Bound(p => p.Top_Perforated_Casing).Title("Top Perforated Casing").Width(84).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Bottom_Perforated_Casing).Title("Bottom Perforated Casing").Width(85).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Base_of_Grout).Title("Base of Grout").Width(65).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Contact).Title("Owner").Width(130);
              columns.Bound(p => p.DIV).Title("DIV").Width(54).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.WD).Title("WD").Width(54).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.County).Title("County").Width(69);
              columns.Bound(p => p.basin).Title("Designated Basin").Width(91).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Management_District).Title("Management District").Width(91);
          })
          .Pageable(pager => pager
              .PageSizes(true)
              .PageSizes(new int[] { 10, 20, 50, 100 }))
          .Sortable(sorting => sorting.AllowUnsort(false))
          .Scrollable(scroll => scroll.Height(500))
          .Filterable()
          .Resizable(resize => resize.Columns(true))
          .Reorderable(reorderable => reorderable.Columns(true))
          .ColumnMenu()
          .DataSource(dataSource => dataSource
              .Ajax()
              .Read(read => read.Action("Wells_Read", "GroundWaterSearch").Data("filterData"))
              .ServerOperation(true)
              .PageSize(50)
          )
)

And the JS 

<script>
    function filterData() {
        return {
            Publication: document.getElementById('publicationArea').value
            //WellName: document.getElementById('wellname').value,
            //StartDate: document.getElementById('startdate').value,
            //EndDate: document.getElementById('enddate').value,
            //ContrArea: document.getElementById('contributingarea').value,
            //WaterDistrict: document.getElementById('waterdistrict').value
            //........ up to 10 additional fields
        };
    }
</script>

And the Controller looks like this:

 public ActionResult Wells_Read([DataSourceRequest]DataSourceRequest request, string Publication, ......add more parameters)
        {
            List<string> criteria = new List<string>();
            GetPublicationArea(Publication, criteria);

           .... additional search criteria

            var tempCalls = CallMgrData.GetGroundWaterLevelsResult(criteria);
            List<GroundWaterSearchResult> values = tempCalls.ResultSet.Select(x => ModelMapper.Map<GroundWater, GroundWaterSearchResult>(x)).ToList();
            DataSourceResult result = values.ToDataSourceResult(request);
            return Json(result);
        }

My question is, what are my options for returning the additional parameters to the Controller?  The View contains complex search criteria (including strings, numbers, and datetime) so I need to return up to 16 parameters from the DataSource.   I don't really want to keep adding a long list of parameters (many would or could be null).  I would rather return a single object to the controller.  I read somewhere I can pass a class object or maybe a json string as the DataSource.Data?  Any help would be appreciated.  Thanks

Hi I have need to display multiple dynamic grid on single page. I created partial view with dynamic grid binding and passing model and method name to bind data from view. First grid displays data and call data read action but rest of the grid do not display data or call method. It shows column names but no data. 

This is partial view

 

 

In main view I am passing list of datatable and in partial view it is getting datatable from ajax call. I have created 3 separate method (ReadData1, ReadData2, ReadData3) in RanData controller.
Thanks in advance.

 

why is there no option to set a drop down list from readonly back into an editable mode?
