Hi All

In order to keep axis labels readable when a chart is resized, one can change the rotation Angle, or simply reduce the # of labels using the Step property. I do have a nifty routine for this,

But, In order to do this my method would have to know the dimensions (e.g. width/heigth in px) of the targeted chart area.

How can I obtain these dimensions?

Hello all,

In my app I use tile layout to let the user manage a bunch of charts and other things. when in "edit mode" I want the headers of the tiles to be displayed, but in "browse" mode I want the headers of the tiles to be invisible as the title of the tile et all is already in the chart displayed in the tiles content.

Using an empty <HeaderTemplate> I still get an empty  one line header for each tile.

Is there a way around this,? Otherwise, please see this as a FR.

Regards,

Hans

I have a datepicker on my page and on load I want to set its initial value to a date I get from a DB table.

I also want the user to be able to pick a date to set it to and it auto updates the page objects base don that new picked date.

I have the auto refresh working on the OnChange event but for some reason I cant set the objects first initial date!

REPL:

I only want my users to be able to add one level of groups to their filters.

For example:

Color = blue

AND

    (

        height > 3

        OR

        height < 1

    )

OR

       foo = bar

I don't want them to add sub-groups to groups (adding an AND group inside of the height block in the above). Is there a way to prevent that from happening in the control?

Hi all, 

I want to remove the word "Sum", and only keep the number at the footer of the Excel file when I export data from the grid as pictures below. Is there anyone know? Please help me.

Thank you

I have two Telerik Grid (Summary & Detail Grid). Detail Grid also have child rows. I need to export to excel for both the grid together in a single file with keeping all the formatting (filtering, freezing, sorting etc). Please provide the solution for this implementation with proper example.

My goal is to have a multi column combo box such that the list changes as the user types in the combo box (by hitting an API) and then when the user clicks one of the items in the drop down I'd like to show the value from one of the columns. I've gotten the first part working but the issue arises when the user clicks on an item.

With the code below what I'm observing is that when the user types in the combo box, the ValueChanged handler fires and gets sent the text the user has typed which allows me to call the API with that value. The drop down displays the data as I expect.  So far so good. Then when the user clicks on an item in the drop down, the ValueChanged handler fires not with the text but with the Id from my model since the ValueField is set to the Id. But I'm also getting an invalid cast error in the browser console. If I change the ValueField to a string, say OrderNumber, the ValueChanged and OnChange handlers fire with the OrderNumber value and I no longer get the error, but the problem is that OrderNumber is not unique so I can't find the distinct item in the collection. So the question is, how do I send the typed text into the ValueChanged handler and send the Id into the OnChange handler? Thanks in advance for your help.

I'm using a TelerikAutoComplete as a filter/searchbox for a Grid. I'm using the OnChange event to call a method that gets the filtered Grid data. It works great until the user clicks the (Add) button to add a new record. At this point, the OnChange event fires again because the OnChange also fires for the OnBlur. 

The effect is that the user clicks the Add button and they see the spinner in the TelerikLoaderContainer for a second or less, and then they have to click the button again to actually fire the event for the button.

I need to move focus away from the AutoComplete after the first OnChange fires, but FocusAsync() doesn't exist for a TelerikGrid or GridCommandButton.

I am using the tiles from openstreetmap and would like to apply a dark mode theme to the Blazor Map component.  There is mention of using the Sass Theme Builder on the overview page, but the Map is not one of the components listed.

Is this possible?

Thanks for any help on this topic.

Hi,

Rendering the whole TelerikGrid in Blazor can be slow when there are lots of rows. How do I update the value in a single cell or row, without re-rendering the whole grid?
