                                    // Access properties of the data item and perform actions accordingly
                                    var addressType = dataItem.intInternetAddressTypeID;
                                    var inputField = dataItem.strInternetAddress;

                                    // Perform validation or other actions based on the properties
                                    if (addressType === "2") {
                                        // Email validation for input field
                                        var emailRegex = /^[^\s@@]+@@[^\s@@]+\.[^\s@@]+$/;
                                        if (!emailRegex.test(inputField)) {
                                            // Set validation message on the corresponding cell
                                            e.container.find("[name=strInternetAddress]").closest("td").attr("data-strInternetAddress-msg", "Invalid email address format");
                                            e.preventDefault(); // Prevent saving the record
                                        }
                                    } else if (addressType === "10") {
                                        // Phone number validation for input field
                                        var phoneRegex = /^[0-9]+$/;
                                        if (!phoneRegex.test(inputField)) {
                                            // Set validation message on the corresponding cell
                                            e.container.find("[name=strInternetAddress]").closest("td").attr("data-strInternetAddress-msg", "Invalid phone number format");
                                            e.preventDefault(); // Prevent saving the record
                                        }
                                    }
                                },

i also enable the tooltip from databound
dataBound: function (e) {
   e.sender.element.find("[data-strInternetAddress-msg]").each(function () {
                                    $(this).kendoTooltip({
                                        position: "bottom",
                                        content: $(this).attr("data-strInternetAddress-msg"),
                                    });
                                });
}but tooltip is not showing in the page , it preventing from saving but not showing tooltip after inspection i found that it creating this html

<td role="gridcell" data-container-for="strInternetAddress" data-strinternetaddress-msg="Invalid email address format"><input type="text" class="k-input k-textbox k-valid" name="strInternetAddress" required="required" data-required-msg="Internet Address is required" data-bind="value:strInternetAddress"></td>


Help me how to show the tooltip not alert i dont want alert

Hi,

I am doing default PDF export functionality of Kendo Grid. But exported PDF file has extra characters in meta data. That results weird title of the PDF in Chrome browser. I have attached screen shot of the exported pdf and also a meta data of the file.  

I found few solutions (https://www.telerik.com/forums/saving-grids-or-charts-as-pdf-and-getting-strange-characters-in-the-metadata) that mentioned that I need to have <meta Charset='UTF-8'> in my code, where grid has been initialized. But I have set UTF-8 charset only in my entire code, still facing same issue.

I have few questions:

1) Which charset value is getting used to export the grid in PDF? (i) <meta Charset='UTF-8'> written in my code or (ii) default export functionality has its own charset value

2)  I am using Telerik.UI.for.AspNet.Core 2020.3.1021 version for kendo UI. Which specific library is being used for PDF generation in Telerik.UI.for.AspNet.Core  2020.3.1021 ? 

3) Is there anything else to try to resolve this issue?

Hi..

I have Radio button. But I don't see the radio getting focus, or any indication that it has focus. How can set the CSS so it show's that it has focus???

 

<input type="radio' id="radio1" class ="k-radio"

 

I have tried...

 

K-radio:focus{

  border: 10px solid red;

 color : red

}

 

nothing

Any ideas?

thx

 

I have a basic Telerik Grid using Batch Edit Mode. This all works great but I have had feedback from User Testing that it is not initially obvious the grid is being used for Data Entry. 

Is there a way I can show the Cells that are editable, by always showing the Inputs / Select Dropdowns without the user having to focus onto the cell first?

I have attached a picture of how the grid looks currently, I would like the inputs / select dropdowns to be visible all the time.

I have been playing around with the new DropDownnTree component (which I love btw) but found that there isn't a "clear" event so I have to use the "change" event which the clear button triggers. The problem is that the value is not reset before triggering this event therefore I can't use it to check if the change event was fired by the clear button.

Dojo: https://dojo.telerik.com/UNIdEjEH

I would think either resetting the component before triggering the change button or adding a clear event is needed.

Thanks.

Hi,

 

hopefully, someone reads my finding.

 

I already posted the issue in ASP.NET Core forum.

https://www.telerik.com/forums/bug-drag-drop-in-grid-within-tabstrip-not-working

 

However, I like to repost it here.

 

Problem description:

When inside a tabstrip the grid loses the ability to reorder rows. 

Example

See dojo: https://dojo.telerik.com/UcEJiSaj

Screenshot

it's impossible to drop the dragged row

 

What I want to achieve is changing the colour of a group on a series based on its category. I have an example below.

So if "Group 1" had a sub group value of "B" the colour is set based on that combination. And that colour might be different to "Group 2" + "B".

So i'm using Kendo's grid but i need a more advanced type of grid. With columns headers and rows headers, but know how to do it. The row headers need to stay under the "Mov Aberto" column.

so I have JS code . In UI I have two radio buttons like communities  and badges . When I clicked on Badges then kendo.data.DataSource transport.Read() method is calling two time but read method should call one time . how can I stop read method for multiple calling. Here I am sharing my code . Can you modify this code by which we can call read method at one time not multiple time

            $scope.searchDS = [];
            var count = 1;

I have a grid that contains several columns.  In the code below I have removed a few just to make it easier to read.  The standard display of this grid has the rows alternating between a light blue and white row color.  I need to be able to change the color of a row based on a specific value in that row.  For example, if the "ReportClassDescription" column is equal to "Express" then the background color for that entire row should be red. 
If it is easier I could also just changed the color of that particular cell.  So again, if "ReportClassDescription" is "Express" then that cell could just be red. 
How can I accomplish either of these scenarios?
