Hello,

I have two grids on one page. The first one has SelectionMode="GridSelectionMode.Single" and the second one is re-reading the data (SQL) based on this selection. I am using Single Selection and handling the SelectedItemsChanged event. This works fine except the first grid is not unselecting the previously selected row so now it displays all previously selected rows.

Click on first grid first row. First grid first row selected. Grid2 content refreshed. That's fine.

Click on first grid second row. First grid second row selected. Grid2 content refreshed. But the grid1 first row is still selected.

I am using UI Kendo 2.1.

Thanks.

Ideally the Telerik control suite should support some level of drag and drop.

The use cases I'm working through require an explorer folder/file tree to be mamipulated, so being able to drag and drop treenodes around. But I can also see use cases for dragging ListView items and content from other containers.

Blazors built in support for drag and drop is not great, so some kind of basic built in support for this would be really handy.

Hi

I have a grid like these

<TelerikGrid Data="@List_GEST_Ordini_Teste_Filtrato" Height="auto"
                 Pageable="true" Sortable="false" Groupable="false" PageSize="20"
                 FilterMode="Telerik.Blazor.GridFilterMode.FilterMenu"
                 Resizable="true" Reorderable="true"
                 SelectionMode="GridSelectionMode.Single"
                 SelectedItemsChanged="@((IEnumerable<ViewListaOrdini> employeeList) => OnSelect(employeeList))">

....

In OnSelect I use the next, to move another page

Navigation.NavigateTo("ordineediting", false);

In 2.9 all works fine, but I've upgraded to 2.10 all stopped to work: OnSelect i called multiple indefinitly

tnx

Hi

I've put a TelerikComboBox inside a TelerikWindow not visible by default.

<TelerikComboBox Data="@ListaUnMis"
                                         Filterable="false"
                                         Placeholder="Selezione Unotà di Misura"
                                         @bind-Value="@selectedProduct.CodUnMis" TextField="@nameof(CMD_UnMis.Descrizione)"
                                         ValueField="@nameof(CMD_UnMis.CodUnMis)" AllowCustom="false" >
                        </TelerikComboBox>

In a grid when I click an edit button I open the modal TelerikWindow and set the selectedProduct.

...but .... the inital valu is not displayed. Remain only blank.

Using TelerikDropDownList all works fine.

Tnx

Hello,

I have a bool column in my grid displaying checkboxes. This works fine. In the column header I have filer's drop-down box with text "All", "Is true", "Is false".

Is there any way to change this text? I need it be All, Selected, Unselected or something else.

Thanks.

 

Hi, 

It seems as though these things only work on the current page. Is there a way to do these things at teh dataset level?

Any guidance would be great!

Thanks  …. Ed

I would like to add a icon in the TextBox, like a search icon, or email or phone. (see attached file) Is this possible?

 

Is there anyway to do an 'addon' button with the TelerikTextBox?

I've tried the following but it puts the button on it's own line:

 

In this case I want to add a way for the user to clear the contents of the TextBox. Another way would be to add an 'X' to the right side of the textbox, but I don't see any documentation to support that method either.  Any suggestions?

Hi

Is their anyway to make the Edit Appointments - ReadOnly - and remove the Save button.

What about removing or changing the labels?

thx in advance
