Hello,

I have a simple grid that works fine. MVC 5 project. jquery read only grid. I added one line only to the grid definition - "toolbar: ["pdf"],":

                        function createHoldingsTable() {
                            $("#gridHoldings").kendoGrid({
                                toolbar: ["pdf"],
                                height: 600,
                                resizable: true,
                                sortable: true,
                                scrollable: true,
                                dataSource: {
                                    data: holdingsData

The holdingsData is json array that populated by drop-down control on the web page. When I click on PDF button then one PDF report generated per a click and that's is expected. Close it and click again - one PDF generated with the same content. If I choose another value in the drop-down box, the grid updated fine and displays new content. PDF button will now generate two PDFs, one have old (for first drop-down value) and another with new content. Changing the drop-down value third time will produce three reports.

I've checked the javascripts and they included ones:

<script src="/Scripts/jquery.unobtrusive-ajax.min.js"></script><script src="/Scripts/jquery.validate.js"></script>

<script src="/Scripts/jquery.validate.unobtrusive.js"></script>

<script src="/Scripts/kendo/2018.2.516/kendo.all.min.js"></script>

<script src="/Scripts/kendo/2018.2.516/kendo.aspnetmvc.min.js"></script>

<script src="/Scripts/modernizr-2.8.3.js"></script>

What I am doing wrong? Where my problem could be?

Thanks.

I need to show a tooltip on the items of a dropdownlist. However I would like for the tooltip to close after one second. I looked on the telerik forums and it seems that it exists but only for ajax AutoCloseDelay

Can this be achieved also in kendo UI for jQuery?

I am trying to make code sample of editable grid with external form.

I followed the the documents at https://docs.telerik.com/kendo-ui/controls/data-management/grid/how-to/Editing/grid-external-form-editing.

I added the property editable:true to the grid and added custom validation for both the grid and the form on the field "ProductName".

The validation rule is that only input which is not "wrongInput" is valid.

I want to change the behavior that in case that the user enter invalid input in the grid then the grid will stay in the same row until a valid input is entered.

Secondly I if the user go to the form and fix the the field there then the corresponding field in the grid will be updated with the correct value.

This is the link to the code https://dojo.telerik.com/anopA

Thanks,

Hi,

I have following code:

    //Autocomplete Gemarkungssuche
    $("#al_gemarkung").kendoAutoComplete({
        minLength: 1,
        dataTextField: "bez",
        select: onSelectAlkisplace,
        enable: true,
        dataSource: new kendo.data.DataSource({
           transport: {
               read: "mod_alkis/gem_search.php",
               //parameter
               parameterMap: function(options, operation) {
                   return {
                       placename: options.filter.filters[0].value
                   }
               }
           },
           schema: {
               data: "data"
           },
           //Filter aufServer nicht Client
           serverFiltering: true
       })
    });   

if I enter a letter everything works fine, but if I go back to the beginning of my input with the backspace key or delete everything in the input field I get the following error in the console:
TypeError: options.filter.filters[0] is undefined
How can I prevent this?

Thanks Sven

I have a DatePicker where I want validation to happen(the message to say something like "Date is already Posted" when a user selects a date from the datepicker that has  Posted(a bool column in the database) value of 1. It will be reading from the column Transaction_Date to look at the date and the Posted column to see if it is true. 

The other possible function would be to disable the date in the datepicker where the Transaction_Date value has a posted = 1 

Either way would work but I would prefer the validation as I plan to disable a different set of dates in the datepicker.

I am having a problem with the inline toolbar editor dropping to the bottom on drag if I am scrolled down on a page. It works just fine if I am scrolled all the way to the top. Once I scroll down whatever the offset calculations are seem to be off and the toolbar drops instantly to the bottom.

The same offset problem is happening to the drop-down menus when scrolled down on both editors, not just the inline. To reproduce be scrolled to the top with a focus on the editor and open a drop down. Then scroll down a little and open the same drop down again. The drop-down appears to render in the same location the toolbar was in before you scrolled. 

Hello, when I   a spreadsheet as follows:

```

$("#spreadsheet").kendoSpreadsheet({
  changeFormat:() => {
    console.log("Change!");
  }
});

```

The callback for changeFormat is not called when I change a cell's styling. However, if I change a cell's format, like currency, number, date, etc, it is called.

Perhaps there is a different event fired for when a cell's styles change? Though I'm unable to find any other event in the list that is even somewhat close to this. The "change" event also does not get triggered in this case.

I'm looking through your docs, and I can't seem to find an easy way to remove the validation on a range of cells.

I've tried passing an empty object to range.validation without success.  Any ideas?
