I want my users to be able to add only one level of groups to their filters. I want to remove the "Add Group" button in the second level toolbar.

===

ADMIN EDIT

===

For the time being, such a result can be achieved with CSS. You can target and hide the "Add Group" button of the desired level to prevent the user from creating another nested group.

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")"> <HeaderTemplate>&nbsp;</HeaderTemplate><Template Context="ctx"><div @onclick:preventDefault="true" @onclick:stopPropagation="true"> -->> THIS part is hitting LOT OF TIME in debug (expected is at best only once) @{if (XSmall==false) { -->> here is LOT OF dynamic buttons. } </div></Template></GridColumn> -->> rest of the dynamic columns. In video, starting with "ciiislo org" in header

@if (GridDef.ColStore != null && GridDef.ColStore.Any()) { foreach (var it in GridDef.ColStore.Where(x => x.Verejny == true)) { <GridColumn @key=@it.FldName Field=@it.FldName FieldType=@it.FldType Title=@it.VerejnyNazev ShowFilterCellButtons="false" Width=@it.cSirkaSestava TextAlign=@it.cZarovnani ><FooterTemplate> @if (it.Sumovat == true) { @context.Sum } </FooterTemplate></GridColumn> } } </GridColumns>

Feel free to change the Subject.

Thanks, have a nice day

Greetings!

I've been waiting for a few months now to swap to blazor, but one of the things that's currently holding us back is that the filter row can't be used together with the column menu.
I've always found this to be strange, since it's supported in the Angular and MVC versions, which we currently use.
Our users never filter via the column menu, always via the filter row. They hide/lock their columns via the column menu and sometimes sort.
This functionality is thus critical for us.

I can't find any feature request for it, nor any planned roadmap item.
Will this ever be supported because if not, we're gonna have to start looking for alternatives.

Kind regards.

Currently, the empty cells in the exported Excel file contain zero-length strings. As a result, the ISBLANK() function returns false for them while the cells essentially do not have content.

Please allow the empty Grid cells to be treated as blank in the exported Excel file.

===

ADMIN EDIT

===

For the time being, you may extend the formula to also check whether the length of the cell content is 0. For that purpose, you may use the LEN() function as suggested here:  https://learn.microsoft.com/en-us/office/troubleshoot/excel/isblank-function-return-false#workaround.

Grid with columns price1 and price2. Enter value in price1, switch to price2, enter value there, and editor is set to old value after async events finish.

The value entered in price2 is correctly set to the property, but the editor reverts to the previous value. If you escape edit mode of the cell, the value entered before the events finish will be shown.

On (fast) tabbing and entering values, this removes the first values entered before the async background events finish.

I tried reproducing the problem in REPL, but could not get the exact same behaviour. In our case no specific value is being set to price2, it just reverts.

https://blazorrepl.telerik.com/cxEzvQvE52q8aaAi27

 

How would you approach preventing the editor from being overridden by other cells' delayed events?

The Grid footer row will not scroll horizontally if:
  • the Grid is initially rendered without columns
  • I am using OnInitializedAsync

Here is a runnable REPL test page. A possible workaround is to render the Grid only if it has columns:

@{
    if (GridColumns.Count() > 0)
    {
        <TelerikGrid Data="@Data">
            <GridColumns>
                @foreach (var column in GridColumns)
                    {
                    <GridColumn Field="@column.DataField"
                                ShowColumnMenu="false" Title="@column.DisplayName" Resizable="true" Width="500px">
                        <FooterTemplate>
                            foo
                        </FooterTemplate>
                    </GridColumn>
                    }
            </GridColumns>
        </TelerikGrid>
    }
}

When initial grouping is set through the state, the GroupFooterTemplate does not render. One has to perform some action for refreshing the Grid in order to display the template - for example, collapsing/expanding a group.

For reference, the GroupHeaderTemplate renders correctly.

Reproduction: https://blazorrepl.telerik.com/wRaJFgFy10vagYnf05

ADMIN EDIT

The GroupFooterTemplate renders with a delay after the Grid. A possible workaround for the time being is to refresh the Grid after it has been initialized to ensure the GroupFooterTemplate will be displayed.

Example: https://blazorrepl.telerik.com/mxkJvAbI17SoNaE148

Is there a way to hide the header?  I'm trying to use the Grid as a ListBox and it almost works using an empty span for the <HeaderTemplate>

I want my users to confirm the update of a cell value with the built-in Confirmation Dialog for Blazor. If I use the keyboard (Enter, Tab) to close the edit the Confirmation dialog will popup, but after closing it the Grid hangs.

Are there any plans to have the datagrid be both groupable and draggable?

Hello

 

What is the purpose of this (https://docs.telerik.com/blazor-ui/components/grid/selection/overview#row-drag-and-drop);

Row Drag and Drop

If the user drags selected rows, the current row selection will be cleared on row drop.

 

Is this a bug? As when you select multiple rows, then drag and drop the rows, it clears the bound selectedItems object (but the rows still remain ticked in the UI). Just confirming this is something that will be fixed?

 

Cheers

Phil

Triggering Edit in a Grid bound to a DataTable or ExpandoObject and with edit mode set to Popup throws an unhandled exception. This started to occur in 4.1.0 - the same code runs fine on 4.0.1

To reproduce:

  1. run https://blazorrepl.telerik.com/cduHQkPS34V0enTc50 (note this is the DataTable demo, but with changed edit mode)
  2. trigger edit mode
  3. observe the unhandled exception

Hello,

Do you have any sample for custom group Header template.

 

e..g. To  calculate the value of the column based on the other fields.

---

ADMIN EDIT

---

Once aggregates for all fields are exposed, we will need to provide an option to align them with the corresponding columns. This can be achieved through a GroupHeaderColumnTemplate which is targeted in a separate request.

ADMIN EDIT: Please review this thread and add your comments so we can get the community feedback on this. We have attached to this opener post a small sample that shows how to achieve this with a few lines of code, and a short video of that behavior.

Hello Team;

The Grid Popup is a great feature, but my understanding is that the Popup form ONLY shows properties that are assigned as columns to the Grid.
If true, this poses some restrictions for us. Many times we might show ONLY small # of columns in Grid, however the form requires MORE properties during ADD or UPDATE.
Is it possible that we can use two ViewModels, one for the Grid columns with less properties and one with more properties for ADD & UPDATE?

Note: If this FR is considered, perhaps we can have separate ViewModel for Update and ADD, as sometimes, ADD might require more properties to be added than later be updated.

This feature will save a lot of time to build apps that have many tables and we have to create CRUD operations

Hi Telerik team,

 

When I want to bind the Blazor Grid to an ExpandoObject I need to assign the FieldType. I know I have to use non-nullable types.

But I want to use nullable types (for example int?) to have a blank cell within the Grid when there is no value for it. With "typeof(int)" instead of "typeof(int?)" every empty cell shows "0" which I don't want.

Is there any chance to let FieldType accept nullable types?

 

Best regards,

Rayko

When using the Filter Menu inside the Column Menu filter value is reset if Rebind is called. For reference, if using FIlter Row or a standalone Filter Menu value is not reset upon invoking Rebind.

I would like to put my "Add new record" button there (which requires this) so that I don't have to use the toolbar - this will let me conserve vertical space.
