I want to show a Kendo window, type something in a textbox in the window, and return the value from to the parent page. How can I do this?

My window definition.

JavaScript to open window

Razor page content for the window

JavaScript for the close where I want to get the value in the textbox in the window but user input is undefined.

Hello,

I am using a Kendo Toobar in RTL mode, and I have a couple of SplitButtons on it.  I have two questions:

1- Since the Toolbar is set to display its contents in Right-to-Left (RTL) mode, the drop-down arrows for the SplitButtons are displaying on the left side (which is understandable).  However, I would like these arrows to display on the right side of the SplitButtons.  How can I achieve this?

2- There is a line separating the drop-down arrow and its text (please see image).  How do I remove this line so that it's one smooth box?

Thanks,

Shawn A.

Hi All,

I created a simple project using the Telerik grid template.  In my script, I update "Freight" to zero for the selected row.   However, I want to set ALL ROWS that match the CustomerID of the selected row to zero.

  Here are the peices:

VIEW

MODEL

CONTROLLER

If this is completely the wrong approach, I'll take ideas for a better/easier solution.

Thank you in advance!

I want to display a line on the value axis of my bar chart. When using JS it can be done like this:

But when using a TagHelper I am missing the "data: [...]" part. How can I tell the notes-taghelper where to draw the line?

Hello,

Is posible to override behavior when multiple option is set, to not holding CTRL button to select multiple dates. I want user to use this behavior as default just by normal mouse click on dates.

Thanks.

I noticed that my ModelState becomes invalid if the user doesn't select any value from a cascaded set of dropdowns.  Once you select a value, it becomes valid.  How do I fix this, and actually save my model if the user doesn't actually select anything?  Not selecting anything just means I won't save anything on Post.

thanks

For a bar chart there is a property Stack

HtmlHelper-Example:

This I can not find in the TagHelper. How can I display a bar chart with stacked bars?

Hello,

I have problem with the ImageBrowser component inside the Editor component in .NET Core 2.2. (It's working in the local example, but I not find the difference)

I use the local example as starting point, I copy the code from the example to my project. 

1. My controller:

2. My view:

3. The result:

[Attached file: teler1.jpg]: It's shows undefined items. The image file structure can be find at the right. The item and file count are equal.

[Attached file: teler2.jpg]: It seems that the control detect the files as a directory instead of file.

4. Reference scripts used:

Can you help me please solve this problem?

Thank you!

I have requirement to allow editable row for one column in Parent row of Parent-Child Grid. I am able to display field in popup window by hiding all other non required field. But I am getting validation message for hide field while update the required field. Please help me to find out the solution either displays only required field in popup window without hiding all other fields or how to stop validation for non-required field in popup window. Below is my code in View:
