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

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

Hi, 

I would like to stop the incrementing of my NumericTextBox when I use the keyboard arrows. I use preventDefault, but it doesn't work.

<div @onkeydown:preventDefault="true">
     <TelerikNumericTextBox Id="test" Width="95%" Decimals="2" Format="C2" @bind-Value="@Test" Arrows="false"> 
     </TelerikNumericTextBox>
</div>

In GridPagerSettings we can configure if show pages as Button OR with an input box.  

In Angular version of Telerik UI il allowed to show pages as Button AND with an input box.

Who to allow this in Blazor UI?

Thanks

Hello forum, does anyone know how can I get the position of GridExcelExportColumn? I need to insert a few Hidden Columns in a specific place on grid's OnAfterExport Event is this the way to go?

GridExcelExportColumn afterThisColumnIWantToInsertHiddenColumns = args.Columns.Find(x => x.Field == nameof(Model.Property));
var index = args.Columns.IndexOf(afterThisColumnIWantToInsertHiddenColumns)

args.Columns.InsertRange(index , hiddenColumns);
