Hello

We are looking for ways to export the UI Blazor TreeList to Excel. I don't see it in Demos and Documentation. Do you have any suggestions on how to accomplish this? Any code examples you can provide?

Thank you!

On the Telerik website, more specifically on Blazor Charts and Graphs - Overview, you can find a nice example of how to change the theme of the charts displayed. We would like to implement something like this in our project. However, a change in the theme affects the entire project. However, we would like the entire project not to be changed and the change in the theme only affects the Telerik chart.

I would like to know if anyone has a good idea for us.

Hi,

Is there a way to set the Y-axis culture directly within the chart? I prefer not to apply the culture globally.

Thank you,
Omar

Hi,

After populating the chart, I would like to clear it. How to clear the chart?

<TelerikChart  @ref="GNChart">

    <ChartSeriesItems>
        @{
            var swedishCulture = new CultureInfo("sv-SE");
        }
        @foreach(var group in ChartData.Select(c=>c.text).Distinct().ToList())
        {
            <ChartSeries Type="ChartSeriesType.Line"
            Data="@ChartData.Where(c=>c.text==group)"
            Name="@group"
            Field="@nameof(ChartDataClass.value)"
            CategoryField="@nameof(ChartDataClass.month)">

I have a Telerik Grid and it freezes when it has almost 3k rows. I have identified two reasons for that.

One: I have put custom margin and padding on cell-level. Suggest me some efficient way to achieve this style without hitting the performance issues

Second: I have a TelerikSplitButton in one of my columns which makes it more slower.


But even removing above two things, plain TelerikGrid still takes about 2-3 seconds to load only 3k rows.

I have pagination on my grid but pagination sizes cannot be very smaller. I need to show Datasets in thousands or more.

Suggest me some best approaches to achieve this with custom design and template.

Multiple clicking on button causing method(SaveAndSubmitClicked) to call twice. Even keeping bool variable(IsClicked ) to disable button not working.

OnClick="() => {IsClicked = true;SaveAndSubmitClicked();

I'm having an issue where my users set Desktop scaling to 300% and as a result my grid will collapse and not show any rows of data making users think there is no data.  I can Ctrl + Mouse wheel to adjust the browser scaling, but that's not really a good option to convey to users.

I've tried using:

Height="calc(34vh - 10rem)"

Property but not really able to solve the problem no matter how much I adjust the values.  What I was hoping to see is a "MinHeight" property for the grid but no such property exists?

Am I seeking something isn't possible with the Telerik Grid?

One of the DropDownButtonItem in my TelerikDropDownButton control is Delete.

The OnClick method for the Delete DropDownButtonItem uses Dialogs.ConfirmAsync to make sure that the user really wants to perform the delete.

The issue is that the Delete button item is still visible when the ConfirmAsync window pops up. Depending on where the TelerikDropDownButton is on the page, the DropDownButtonItem overlaps the ConfirmAsync window.

Here's an example that shows the DropDownButtonItem is visible when the popup is displayed: https://blazorrepl.telerik.com/GylvcgFS09nqh4ZM26

Is there a way to hide the DropDownButtonItem after it is clicked?

Hi,

Hi I am writing an app where user can upload files (multiple at once) and each file will have custom data attached to it.

How do I access individual files and attach custom data to each file once I load them into the select file grid?

Almost like a SelectedItem event in a grid where I can access the individual files which I click on it.

I can use the OnUpload and OnSelect to send custom data and look through all the files but They aren't bind to the individual file.

Example, I have data like a description for each individual files that I want to send with it when I upload and write to the database. How do I bind that data to the file?

I am working with an excel template (.xlsm) that contains dropdowns, buttons, images, charts and few shapes. I use Telerik radspread processing to read this template and insert data into it. However, when I download the modified excel file (.xlsm), these elements are missing.

It seems that RadSpread Processing is unable to read or preserve these elements. Is there a way to retain them when manipulating .xlsm files, or any workaround to handle such cases?

Any guidance or suggestions would be greatly appreciated.
