Using CheckBoxList filtering changes the filter menu for all columns. I would like to specify CheckBoxList only for certain columns, but that doesn't currently appear to be an easy option.

1) Leave as FilterMenuType "Menu" but implement a custom filter template for the columns I want. That would be the most obvious, but CheckBoxList is not a usable control on its own?

2) Or do the inverse, use FilterMenuType "CheckBoxList" and implement a custom filter template for all the columns where I don't want to use that. Seems like a lot of extra work to manually recreate default filters.

3) I guess I roll my own clone of the CheckBoxList control and use that like #1 on individual columns?

Any chance the CheckBoxList control could be publicly exposed for direct use?

When you scroll to the right in a grid and filter so that there are no items, the horizontal scroll disappears and you can no longer come back to the filter in order to clear it and work with the grid again.

Hello,

 new version has broken "dynamic" changing column properties/visiblity runtime, especially- selection mode and causing lot of "rerendering".

Video attachment:
1 - first part is OLD version(prior 4.1.0) 4.0.1
2 - seccond part(after changing next browser tab) is new version 4.1.0

SAME setup
Iam already using hint for blazor with IDs of columns, found in Your documentation...etc. @key="@("sIDX")"

.....
-->>Clicking on Button for changing grid mode and visibility of columns**
<TelerikToggleButton Title="Oznaceni vice radku" Icon="@FontIcon.ListUnordered" OnClick="@( _  =>{ CurrentStackItem.gSelectionMode=(CurrentStackItem.gSelectionMode==GridSelectionMode.Multiple)?GridSelectionMode.Single:GridSelectionMode.Multiple;CurrentStackItem.gSelectedItems = Enumerable.Empty<ExpandoObject>();})"
				Selected="@(CurrentStackItem.gSelectionMode==GridSelectionMode.Multiple)"></TelerikToggleButton>
....
<GridColumns>
-->>First "static" 2 columns**
<GridCheckboxColumn Visible=@(CurrentStackItem.gSelectionMode==GridSelectionMode.Multiple) @key="@("sIDX")" Width="70px" Locked="true" SelectAll="true" SelectAllMode="GridSelectAllMode.Current"></GridCheckboxColumn><GridColumn FieldType=@typeof(bool) Visible=@(IsPicker==true || (XSmall==false && CurrentStackItem.gSelectionMode==GridSelectionMode.Single )) @key="@("sCMD")" Filterable="false" Sortable="false" Locked="true" Width="@((IsPicker==true && XSmall==true)?"45px":"120px")">

-->> here is LOT OF dynamic buttons.

				}
					</div></Template></GridColumn>

-->> rest of the dynamic columns. In video, starting with "ciiislo org" in header

Thanks, have a nice day

Hello,

I seem to have stubled upon a strange bug in TelerikGrid. We have wrapped a TelerikGrid and the Columns are also wrapped to allow special actions.
The bug is present in "raw-telerik-code" as well.

We have an edge case where we have a TelerikGrid and some of its columns should be Locked (Stickied/Frozen) as a default behaviour.
But depending on user interaction we want to change the state. We cannot use a property for each column that we want to be Locked/Unlocked as it should be handled by the GridState.

When the Column is using default behaviour (not Templated), it works as intended. But as soon as you use a <Template> for the Column, the Locked state cannot be changed from the default/supplied value.

TLDR: Programmatically changing the Locked state of a column where the cell is templated will not change the locked state.

I have prepared two REPL examples. One for 3.7.0 as it is what we currently are using, and one for 4.0.1 as to prove that it still exists in the current itteration.

3.7.0
https://blazorrepl.telerik.com/cHEHurlI06olUsJ410

4.0.1

With best regards

I would like to be able to customize the default format for dates and numbers that the grid has to, for example, use the current UI culture of my app.

As of UI for Blazor 4.0. ExcelExportableColumn is inaccessible due to its protection level and GridExcelExportColumn should be used instead.

I am trying to add the hidden columns to the exported file through the OnBeforeExport event. However, I am unable to create an exportable column instance using the GridExcelExportColumn. I get the following error:

CS1729: GridExcelExportColumn does not contain a constructor that takes 0 arguments.

The GroupFooterTemplate works great for showing aggregate values per group.

Need the same functionality for the entire Grid, ie, sum of all values displayed for a column even if no grouping is applied.

A Blazor Grid column having a boolean data type field should display as checkbox instead of the text True/False.

A checkbox is a fine representation for the end user, True/False may be ok for a developer ;-)

Editing the boolean value by a checkbox is already fine.

The Custom Filter Menu in the Grid is not working as I would expect.

I am trying to do two things

1. Apply filters programmatically through the Grid State
2. Populate a custom Filter Menu with values that exist in that column

I am doing something very similar to the demo for the custom filter menu: https://demos.telerik.com/blazor-ui/grid/custom-filter-menu

I have observed that if I set a filter programatically through the grid state, those filters are applied to the grid but are not being passed through the FilterMenuTemplateContext object in the FilterMenuTemplate when I open the Filter Menu for that column.  Therefore, I cannot update my custom filter to show which values are currently being filtered on.

Is it by design that the FilterMenuTemplateContext does not contain Filters applied through the grid state or a bug?

ADMIN EDIT

As of Dec 2020, there is one outstanding issue - using complex filters (having a CompositeFilterDescriptor) for the FilterRow filter template gets saved in the grid state, but is not loaded as expected - the filter row uses a "regular" FilterDescriptor and cuts off additional descriptors. Thus, the context of the template does not provide all the data from the grid state and you need to extract it manually. I have attached a sample that shows one way of doing that in the StateInit handler.

The FilterMenu already provides all the data in its context and you can bind inputs in the template directly to the filter descriptors. Once the filter row can work with more complex filter descriptors as well, you would be able to create the extra descriptors (if they are not already there) and directly bind the inputs to their value, as opposed to the current approach where view-model fields are used.

Hello,

First of all: thank you for implementing the Excel like filtering with the new CheckBox Filter! This was a feature that was highly sought after in our development team.

But there is one thing I am missing: the checkbox list has no option for sorting.

If we want to sort our filters now we have to implement the FilterMenuTemplate in every column that has filtering active (which are a lot) and define the list with filter options and filter it ourselves. 

Is this something that can be fixed easily?

---

ADMIN EDIT

We will probably sort ascending the values by default (out-of-the0box), and any other custom sorts should be implemented through the filter menu template.

---

How do I get the filter menu to allow input of Date *and* Time for a DateTime column?

Grid column header and content alignment (horizontal +Vertical)

---

ADMIN EDIT

For the time being, this is possible through the CellRender event, see below in the thread for an example.

Description

The left offset style value is not correctly formatted. It is culture-specific, however, the CSS rules should be formatted with culture invariant decimal separator - dot. 

Reproduction (if bug)

1. Create a grid with locked columns. 

2. Set the culture to one that has a comma as the decimal separator.

3. Resize the frozen columns, the left value is formatted with a comma instead of a dot.

Expected (if bug)

The value should be formatted with a dot.

Browser (if bug)
All

Project type (if bug)
All

I want to place the Pager on top of the Grid. I know it can be handled with a Pager component integration in the Grid Toolbar, but I want to use the Toolbar for other purposes/actions. Please allow control over the Pager position.
