I have a grid which has ServerOperations set to TRUE.  The total number of records is very large, so we're only displaying 20 at a time.  One of the columns contains a filter dropdown containing a list of checkboxes for selecting specific values to filter on.  I want the Filter dropdown to include ALL possible values for the user to choose from...not just the ones that are returned for each page.  Is there a recommended approach for doing this?  (I have provided the grid initialization code below...)

Hi,

I am trying to do inline editing on a local datasource provided from a controller source. 

When I add the command button I get the following error:

System.InvalidOperationException: 'The parameter conversion from type 'System.String' to type 'System.Boolean' failed. See the inner exception for more information.'

This is the error message: 		"-1 is not a valid value for Boolean."

I'm wondering what I am doing wrong.

Thanks

Sean

I use a kendo Splitter with 2 vertical panes (top-pane and bottom-pane).
Inside the top-pane .Content( ), I have a Kendo TabStrip with 3 tabs. Inside the bottom-pane .Content( ), I have a DropDownList / textbox controls and one input button "Save".
When the Main View page loads, my Main Controller Action retrieves the data and return the MainViewModel for my DropDownList / textbox controls and determines which Tab to select (ie show) to the user.

Here is my Kendo TabStrip on my main view with the MainViewModel

Each of the tabStrip .LoadContentFrom( ) calls the action "ConditionAction" to load data in the tab's corresponding PartialView.

With the codes that I have so far,  displaying the right data for the appropriate tab contents works.

My problem is when user clicks on the "Save" button (at the bottom-pane), how do I read from the form data of the Tab that I want.

For example, user clicks "Tab 2" and types some inputs in Textboxes, then clicks the Save button. I just want to read the form in Tab2 and save its data. (form in Tab1 and Tab 3 are ignored) and additionally read the main form controls (DropdownList etc) and save as well all at the same time.

I was planning to do an Ajax call onClick of the Save button. But don't know how to read and pass the PartialViewModel to my Controller.

Any suggestion? 

I am using the kendo dropdown tree with vuejs. Below is how I am using the dropwdowntree.

The "mySelectedList" contains an array of IDs. If the form is being edited and the array is populated, this array will check items on the dropdowntree. This is as expected.

But as items from the dropdowntree are checked or unchecked by the user, this array "mySelectedList" does not get updated.

What is the proper way to bind a property to the dropdowntree?  How do I get "mySelectedList" to get updated as the user checks or unchecks items in the dropdowntree?

<dropdowntree 

:data-source="myDataSource"
autoClose: false
:checkboxes="true"
:check-all="true"
:placeholder="'Select from tree'"
dataTextField="text"
dataValueField="id"
v-model="mySelectedList"
>
</dropdowntree>

I have been trying to get a scheduler to show simple events, but Im doing some wrong (probably something simple I'm not seeing.

I have a field in a grid, which is a nullable Boolean. However, the filter option for this field, shown by the grid just has options for true and false.

This is obviously incorrect for a nullable Boolean, which should also show a filter option for null.

How can I rectify this?

I'm using version v2021.1.119 

Thanks

Hi,

I am trying to use the same Dropdownlist in a parent grid, and its hierarchal/child grid. This Dropdownlist was written in jQuery and is kept inside the Shared/EditorTemplates folder and works as expected for the parent grid. However, when I apply it to columns on the child grid, it does not appear. It ignores the template and prompts me for an input like usual for inline editing instead of displaying the dropdownlist options.

Is it possible to use the same EditorTemplate inside of a hierarchy grid?
