I have a TelerikDialog who host a component, when some logic occurs on component i would like to hide the dialog buttons, now i can do this for each button inside DialogButtons element, but this cause the dialog to show some empty space with a separation line.
I would like to hide entirely the DialogButtons element to prevent showing empty space, i tried with hidden html attribute or @if statement but it's not supported.
There is a workaround?
It woud be glad to have a Visible property on DialogButtons component in future releases.
I am trying to create something I've seen a lot on other websites. I want to create a tooltip that shows "Copy to clipboard" when I hover over a <span> element, but when I click on the <span> I want the text to change to "Copied!"
This is what I am doing now
<TelerikTooltip TargetSelector="#propvalue>span[title]" Position="@TooltipPosition.Top" ShowOn="@TooltipShowEvent.Hover" @ref="@tooltipHover">
<Template>
@{
<div>
@copyToolTip
</div>
}
</Template>
</TelerikTooltip><span id="myCoolSpan"
style="cursor:pointer;"
onclick="@(()=>_copyButtonHandler(value as string))"
title="this is the title">
Text of my span
</span> private async Task _copyButtonHandler(string value)
{
copyToolTip = "Copied!";
await _clipboardService.WriteTextAsync(value);
}Hi, I'm using TelerikMultiSelect with grouping. I tried to create a custom filter on the group field, but the value entered by the user cannot be read. Do you know how to read the value?

Here's a code snippet demonstrating the issue:
https://blazorrepl.telerik.com/cRODPclB17lz8CCi20
Row drag and drop works like in the documentation example, except the indicator to show where the row will be dropped is missing.
If you press escape this both cancels the drag and drop and closes the window. It also shows the indicator where it would have been, and there is no way to remove the indicator without refreshing the page.
How can this issue be resolved?
I populate the Grid with ~5000 results from a database. The Grid does the paging, sorting, and filtering in memory, except it won't filter for this one column that is a List<string> CustomerNamesList. I'm attempting to use the FilterMenuTemplate -- I just need a textbox and a dropdown like "Contains" and "Does Not Contain" but I can't figure out how to filter the Grid.
<GridColumn Field="@(nameof(CustomerNamesList))" Title="Customers" Sortable="false" Filterable="true">
<FilterMenuTemplate>
<label for="NameMenuFilter">Customer Name:</label>
<TelerikTextBox Id="NameMenuFilter" ValueChanged="@((value) => UpdateCustomerNameFilter(value))">
</TelerikTextBox>
</FilterMenuTemplate>
<Template>
@* display - loop thru List of customer names *@
</Template>
</GridColumn>
This code gets hit, but it's not doing anything...
public void UpdateCustomerNameFilter(string itemValue)
{
var filter1 = partyNamesFilterContext.FilterDescriptor.FilterDescriptors[0] as FilterDescriptor;
filter1.Value = itemValue;
filter1.Operator = FilterOperator.Contains;
}When I click Filter, it gives me a blazor.server.js error
Error: System.ArgumentException: Provided expression should have string type (Parameter 'stringExpression')
Update
Here's what I'm using as the datasource to make things clearer: IEnumerable<Companies>public class Companies
{
public int Id {get; set;}
public List<string> CustomerNamesList {get; set;} = new List<string>();
// Other fields
}

Hi there.
Using the Grid component, setting "Navigable" to "true" and having a DropDownList makes the popup of the component not appear after the user has clicked on the input box.
The DropDownList has a button (with an arrow pointing down) on its right side. Clicking on the button makes the popup appear. The popup also appears if the user clicks on the input box of the component, but this last scenario does not happen if the component is inside a Grid which has "Navigable" set to "true". In this state, the button mentioned also makes the popup not appear.
Here is a gif which showcases this behaviour: https://i.gyazo.com/a071f9fba72d08261d438e31b240d606.mp4
This also affects the ComboBox component: https://i.gyazo.com/bcf2f10a6a6c923d825865ecdf0a7f5a.mp4

Hi,
I am trying to do something simple but having trouble.
All I want is a grid that displays columns for a name and an IsActive property.
I tried using:
<GridCheckboxColumn Field="@(nameof(AppRole.IsActive))" Title="Is Active"/>
but got nowhere with it.
The basic code is show below. How can I center the checkbox in the column and make not editable unless the are in edit mode?
Also, I want the checkboxes centered in the column.
Any help would be great.
Thanks … Ed
