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.

I would like to export custom data to excel, for example - the selected items.

 

<AdminEdit>

As an attached file, you can see a sample implementation that shows how you can export the Selected Items from the Grid to excel.

https://docs.telerik.com/blazor-ui/components/grid/editing/incell#notes 

I am using an EditorTemplate with a method called ChangeHandler(). After clicking in another row everything works fine but if I leave the cell by pressing enter the UpdateHandler gets called more than two times and comparing args.Item with the GridItem doesn't help because the calls are asynchronous.

Admin Edit

With 2.22.0, the InCell editing mode was revamped to provide better user experience and this alters the way it worked. In the common case, there will no longer be double OnUpdate calls (unless explicit application logic invokes them). With 2.23.0, Tab and Enter keys that bubble from editor templates will be handled by the grid like they are handled for the built-in editors.

This means that this issue is, effectively, solved. You can see the Notes section about editor templates to see how you can also handle the OnBlur event to capture mouse clicks outside of the component so that you can save changes and remove the edited item. See the full notes here (the Event Sequence section was heavily revamped for clarity) and here on editor template behavior.

Thus, the previous ides about  Save and Cancel methods on the edit context might not be implemented, which will also be one breaking change that we could avoid:

After discussion with the development team, the proposed resolution is to provide a context that provides Save/Cancel operations. The goal is to provide easier configuration for IncellEditing and EditorTemplates and consistent behavior with mouse and keyboard interaction. However, the change will introduce a breaking change in our EditorTemplate, should be researched further and that is why this is logged as a feature request.

I want to reduce length of pagination selection below the grid  ( currently is showing as   << 1  2 3 4 5 6 7 8 9 10 ...>>     but I want to have it like << 1 2 3 ....>>)

I want to fetch grid records page per page according to the appropriate filter settings. While this is possible through the OnRead event, I want to be able to send the request to the server so that it is easier to fetch the data, like in the UI for ASP.NET Core grid. Currently you can do this only for a server-side project because you can pass the request object by reference, but for a WASM project it needs to serialize in an HTTP request.

You can find examples of doing this here: https://github.com/telerik/blazor-ui/tree/master/grid/datasourcerequest-on-server

I am editing parent and child records in the hierarchy grid.  I can edit parent and child records without issue.  The only problem I have now is this; when I click edit on a child record, then collapse the parent, the edit of the child record is lost or cancelled but there is no event I can see to use to put things back in non-edit mode.

I enable buttons and links in non-edit (view) mode and disable them when editing a record.

So,  is there an event or some way to know the user is collapsing or expanding a parent record?

 

Thank you,

It would be nice if the title of a column is fetched from Display(...) or DisplayName(...) attribute of field.

Allow end users to drag the columns into an order of their choosing

Please allow to set Group By fields at Design time, currently only user has control to Drag and drop to group.

we need feature to group by fixed set of columns and don't allow user to change the grouping, also need option to hide group collapse icons.

 

 

Currently the blazor grid must be a specific, static height.  If one is not provided, the grid uses a default of 500px.

Kendo grid implementations in other UI frameworks allow for more flexibility in the height of the grid.  It would be great if the blazor implementation could support this as well. 

Two specific scenarios that are valueable:

1) Grid height adjusts to accomodate all of the items in the grid

For other kendo grid implementations, this is typically the case when "Scrollable" is set to false.   If there is a plan to allow toggling scrolling for the blazor grid, then I think that this would come along with that.

2) Ability to set grid height to 100%

With other kendo implementations this is normally done via CSS, and is useful for when you want a "full screen" grid.  This is normally combined with "Scrollable=true" and often combined with Pagination="true" as well.   Currently it's not possible to do this - since the height is defined on the k-grid element, it cannot be overridden with CSS.

Hello there,

 

I am looking for the ability to display hierarchical data in the grid control similar to that available in the asp.net core grid: https://demos.telerik.com/aspnet-core/grid/hierarchy

 

Thanks!

Using the Excel Export for Grid creates the Excel file, but on opening it, the columns that contain data are hidden. Unless I unhide the columns, the sprceadsheet looks empty.

ADMIN EDIT:
One idea to go about this is to expose an event that would allow users to modify the column width values before they get sent for export. The benefit of this approach is that if the columns are resized, the user will receive their current size in the specified unit e.g. rem, em or % and will be able to set the width in px.

Another idea is to default such column widths to some hardcoded value (say, 64px) or even the grid might try to calculate them (which can cause questionable results in stranger settings, but it is an idea - if an event gets exposed you will be able to do that in your application code).

Horizontal scroll bar is visible, but doesn't move with cursor/current-cell.

ADMIN EDIT

Applies also to vertical scrolling with or without row virtualization (e.g., using InCell edit mode, pressing Enter will open the next row for editing, but it will not work out with row virtualization at all after the current viewport, and without virtualization you will not see what's happening until you start typing and the browser calls .scrollIntoView() for the editor)

At the moment the numeric and date filters keep the filter button visible even on narrow columns. This must be implemented for the string filter as well - it has a set width at the moment.

The "clear filter" button must always be visible as well (when there is a filter applied, of course).

Ideally, the filter elements will also have a common container with an accessible class so, for example, you can set its max-width to 50% or 100px to match desired UI easily without hacking through several different layouts and selectors.

Would like a parameter in the grid definition that would display a Clear/Refresh button to return the grid to all originally selected records.  This feature would work similar to the Excel clear filter function.  

At the moment it is not allowed, but I would like to freeze a few columns in the 100 columns that I have, and I use column virtualization for.

Is there any way to default the values that are used when I create a new row?

So for example, I have a row where I want to default a date to Jan 1st of the following year.  However, when I add the row, it adds nulls to all fields and the date shows up as 1 Jan 1900 and there's a lot of fiddly clicking to set the right date.

Does the grid support groups and group headers? Didn't see an example.

It is a common request to show grids in alternating colors, rather than simply white and grey.  Because the Grid component generates the <tr> element, we are left with manually setting each <td> element.  A tedious but effective solution.

The feature I would like to request is to add 2 new tags to the <TelerikGrid> component, call them EvenRowClass, and OddRowClass.  The behavior is the same as the Class tag, but they operate on Even and Odd numbered rows of data, respectively.  Their values would be added to the <tr> element as <tr class="MyEvenClass"> or <tr class="MyOddClass" in the same manner class k-alt is generated or not.  This would provide a simple yet extensible mechanism to achieve custom alternating row colors in a Grid.

 

When binding to an observable collection, and the data source changes, the current behavior is that the page index remains the same (let's say, page 4). If the new data source has less data, you will see nothing. In such cases, the page index should remain the same only if there is sufficient data. If there isn't, it should reset to the first page.
