Hello,

Looking for an easy solution to enable/disable all grid rows based on other values/selections on the page.

The following selectable parameters for the grid gives me exactly what I need but I need to be able to configure the grid based on the user's input values on the page.

.Columns(columns => {
    columns.Bound(e => e.Id).Hidden();
    columns.Select()
        .Width("20px");
    columns.Bound(e => e.Name)
        .Title("Name")
        .Width("400px");
    columns.Bound(c => c.Description)
        .Title("Description")
        .Width("400px");
})
.Selectable(select => select
    .Mode(GridSelectionMode.Single)
    .Type(GridSelectionType.Row)
)

 

I've tried using the following jquery to toggle the rows, with no luck.  'enabled' is the parameter passed to the function.

var grid = $('#grid').data('kendoGrid');
 
grid.items().each(
    function (index, value) {
        $(value).find('.k-checkbox').attr('disabled', !enabled);
    }
);

 

Any suggestions on how I can achieve the functionality needed with the grid component?

Thanks.

Jason

Are Razor Pages supported by the Forms widget.  I keep getting an unhandled exception caught in the middleware after the Exception Handler has completed and nothing is returned just the <div></div> that I placed around it

The demo here: https://demos.telerik.com/aspnet-core/autocomplete/clientfiltering

is missing this script which is in the other demos.

<script>
      function onAdditionalData() {
      return {
          text: $("#[your control's name]").val()
      };

</script>

It would be helpful to be able to report these things from the page.

I'm building an ASP.Net Core app that fills PDF documents and saves them. I had planned on building it to run on Linux servers and develop on a Mac. But....it appears the document processing libraries are Windows-only? I get an error stating"Could not load type 'System.Windows.Point' from assembly 'WindowsBase...". Is this the case? Does this have to be built and ran on a Windows machine?

I am trying to place an Editor inside of a pane in a Splitter. The only problem is that the Editor goes past the end of the Splitter when I set the height to 100%, creating overflow in the pane, which I have hidden.

The workaround that I have found is putting the editor to have a height of calc(100% - 0px), but I feel as though this should not be necessary. Have I missed something here?

 

Here is the Tag Helpers with the editor height at 100% which produces the overflow.

 

<kendo-splitter name="cp-homepage-splitter" orientation="SplitterOrientation.Vertical" style="height:100%;">
    <pane size="115px" collapsible="false" resizable="false" scrollable="false" id="cp-homepage-top-pane">
        <p class="iv-title iv-title-2">Home page</p>
        <p class="alert">Set the content for the first page shown.</p>
    </pane>
    <pane collapsible="false" resizable="false" id="cp-homepage-bottom-pane" style="height:100%;overflow-y:hidden;">
        <kendo-editor name="HomepageEditor" aria-label="editor" style="height:calc(100% - 0px);">
            <resizable enabled="false" />
            <tools>
                <tool name="bold" />

Standard List View, nothing special. In the template, there is an "a href" link which redirects the user to a details page for the item.

The user clicks on the item, which redirects them to the details page, this works well.

The problem is when the click the "back" button on the browser to get back to the list view, the paging starts at page 1 and not the page they were looking at (example: page 5)

How can I retain the current page value? I guess I need somehow to fetch the current page the user is looking at, and then store it in a session variable. Thanks for the guidance.

Hello,

I've followed the example found here: https://demos.telerik.com/aspnet-core/grid/remote-data-binding to create a grid that is bound to remote data.  Everything works great.  However, my IT security team has run the Rapid7 Appspider security scan  on my web application and all that comes up is "vulnerabilities" related to the scanner sending bogus values for the filter, sort, and group parameters to the Grid controller.  Here's an example:

Attack type:  Buffer Overflow string of 100 characters

Basically it's sending a string of 100+ characters as a value to the "filter" parameter.

https://mysite.com/Grid/Orders_Read?filter=100characterlongstring

In other cases, it's sending potential harmful strings such as ./*][ and %s%f%d%x.  The Grid seems to handle it by returning an error, but they may force me to handle/validate these parameters.  The problem is I don't see where/how I can do that?  Can you please shine some light on how I can prevent these "vulnerabilities"?

Thanks

I have 2 dopdowntree's with checkboxes on my page. They are basically cascading, depending on what they choose in #1 it will fill the 2nd one with specific options.

When the user clears all selections from the 1st one I want to clear out everything in the 2nd and reload its data with the default options.

All I'm doing in my code when they clear everything from #1 is this

 

var secondDDT = $("#ddt2").data("kendoDropDownTree");
secondDDT.dataSource.read();
secondDDT.value([]);

 

What happens is that it does indeed reload the data in #2, and if I open the dropdowntree, there is nothing checked in the control, so it has cleared the checked items. The issue is that the items are still showing up in the multiselect view of the control (see attached)

Additionally, the items that are still displaying in the multiselect view of the control are now 'frozen', you cannot manually delete them from the dropdowntree with the little 'x'. When you look at the html you can see how all the nodes have unselectable="on". Also you can see the select tag witht eh options in it. I tried clearing that manually in script but it made no different. What's going on here and how do I fix it?

 

<div class="k-multiselect-wrap k-floatwrap" unselectable="on">
    <ul role="listbox" unselectable="on" data-template="tagTemplate" data-bind="source: tags" class="k-reset" id="3c0fe359-03e8-467f-b301-838dd5d7cd37_tagList" data-stop="true">
        <li class="k-button " unselectable="on" role="option">
            <span unselectable="on">DummyItem1</span>
            <span title="delete" aria-label="delete" class="k-select">
                <span class="k-icon k-i-close"></span>
            </span>
        </li>
        <li class="k-button " unselectable="on" role="option">
            <span unselectable="on">DummyItem3</span>
            <span title="delete" aria-label="delete" class="k-select">
                <span class="k-icon k-i-close"></span>
            </span>
        </li>
        <li class="k-button " unselectable="on" role="option">
            <span unselectable="on">DummyItem5</span>
            <span title="delete" aria-label="delete" class="k-select">
                <span class="k-icon k-i-close"></span>
            </span>
        </li>
   </ul>
    <span unselectable="on" class="k-input k-readonly" style="display: none;"></span>
    <span unselectable="on" class="k-icon k-clear-value k-i-close k-hidden" title="clear" role="button" tabindex="-1"></span>
</div>
<select id="ddt2" multiple="multiple" name="ddt2" style="width: 100%; display: none;" data-role="dropdowntree">
    <option value="31" selected="">DummyItem1</option>
    <option value="29" selected="">DummyItem3</option>
    <option value="33" selected="">DummyItem5</option>
</select>

Currently i can't find an option for radiobuttons like the one for other editors : 

 

i.e. :     .Editor(e =>
                    {
                        e.NumericTextBox();
                    });
            });

 

What is the best way to add radiobuttons in the form since the form component doesn't seem supporting the radiobutton standard?
