Hi

Using Filtermenu  , an user set a filter on multiple columns,  i want to save  this filter in the database and reuse it later.

Is this possible.

Also when filtering , the user can not see what filters he or she placed.

Can it be possible to have a grid property that describes the filter like

( A > 10)  And ( (B=2) or B=3)  ) and COUNTRY = 'USA" ?

This way we can drop a label and attach t to the property

Hi, I was looking for a way to specify that a grid column should toggle thru the ListSortDirection in a different order. By default it appears a sortable column toggles through its sort directions in this order:

1st click to sort - Ascending

2nd click - Descending

3rd click - no sort

That works for a majority of our grids and their columns (primarily strings and numbers) but we have some columns like 'Last Modified' dates that I'd like it to:

1st click to sort - Descending

2nd click - Ascending

3rd click - no sort

This would also be more intuitive with our grids that we set their initial sort column to a date column in Descending order on page load. The 'first sort' a user expects is Descending on those columns.

I assume there's a way to use OnStateChanged to do this but it'd involve tracking state changes ourselves and other custom code to try to indicate a certain column should toggle sort directions through different orders. Way too much work for us to introduce into our product at this time. Other tech stacks provide a way to specify the toggle order via column properties, and was hoping such a feature either existed or could be added. Thanks!

I like the ability to select a row by clicking on a checkbox. But the handler for clicking on the row supplies the contents of the row where as putting a GridCheckbox like

only gives me the state of the checkbox. Is there anyway to have the row click handler also respond to the checkbox? Or how can I get the contents of the row that the checkbox that was clicked is on?

Hi,

Is it possible to get event when user click/double click task on Gantt chart (grid/timeline). We should update some properties based on selected task.

Is it possible to create new dialog for popup editing?

I am trying to use the Telerik.Blazor.Components.TelerikNumericTextBox.  

Upon opening the form in question, I receive the following in the output window:

   [2022-05-18T14:08:20.156Z] Error: System.AggregateException: One or more errors occurred. (Format specifier was invalid.)
    ---> System.FormatException: Format specifier was invalid.
      at System.Number.NumberToString(ValueStringBuilder& sb, NumberBuffer& number, Char format, Int32 nMaxDigits, NumberFormatInfo info)
      at System.Number.FormatDecimal(Decimal value, ReadOnlySpan`1 format, NumberFormatInfo info)
      at System.Decimal.ToString(String format, IFormatProvider provider)
      at Telerik.Blazor.Common.Parsers.TelerikGenericDecimal`1.Format(T value, String format)
      at Telerik.Blazor.Components.TelerikNumericTextBox`1.get_FormattedValue()
      at Telerik.Blazor.Components.TelerikNumericTextBox`1.get_Text()
      at Telerik.Blazor.Components.TelerikNumericTextBox`1.GetNumericTextBoxOptions()
      at Telerik.Blazor.Components.TelerikNumericTextBox`1.OnAfterRenderAsync(Boolean firstRender)

The razor markup for the control is:

                <TelerikNumericTextBox  Width=@ControlWidth.ToString() 
                                        @bind-Value="@NumericValue"
                                        Decimals="2" 
                                        Format="D" 
                                        Id=@FieldProperties.Field_Name
                                        OnChange="@TextOnChangeHandler"/>

Right now the control is bound to a Decimal Property  (public decimal NumericValue)

and the initial value is hardcoded to 1200.26M

Any assistance would be appreciated.

Hello -

I've been really enjoying my time with the Telerik Blazor Grid component, but I'm running into trouble with the filtering functionality.  This is using a Blazor Web Assembly Client with a ASP.NET Core 3 backend.  When my client requests data from the API without a filter, I get appropriate responses as expected.  Paging works great, everything is good.  As soon as I try any off-the-shelf filter, I get an error response from the server with the message :

Could not create an instance of type Telerik.DataSource.IFilterDescriptor. Type is an interface or abstract class and cannot be instantiated.

It looks like this is some sort of deserialization error that is being run into when the server is trying to parse my DataSourceRequest.  It gets parsed fine without a filter, but as soon as I try to filter, I get the above message.

Has anyone else seen and tackled this problem?  Thanks much!

I don't see any loading indicator when going between pages of a grid with remote data... are there plans for this?
