Hi Cemil, 

In default dialog, we handle click events for ok and cancel button internally in order to save the edited value and cancel the editing action internally. While rendering custom dialog we need to manually update the record using updateRecordById method. In the provided sample we rendered custom dialog with Name field. On change event of ok button, we have updated the record using updateRecordById method. This method will update the values in Db also. So, Gantt can be reloaded with updated records Please find the below code snippet. 

 

[Index.razor] 

 

<SfDialog ID="DialogContainer" @ref="Dialog" Width="700px" IsModal="true" Header="Add Custom Dialog" @bind-Visible="@IsVisible"> 

        <DialogTemplates> 

            <Content> 

                // Render Textbox for ID  

               <SfTextBox ID="InputIdContainer" @ref="InputId" Placeholder="Id" Width="300px" Value="@Id" Enabled="false"></SfTextBox> 

               // Render Textbox for Name 

                <SfTextBox ID="InputNameContainer" @ref="InputName" Placeholder="TaskName" Width="300px" Value="@Name"></SfTextBox> 

            </Content> 

        </DialogTemplates> 

        <DialogButtons> 

            <DialogButton Content="Ok" OnClick="@OkDialog" ></DialogButton> 

            <DialogButton Content="Cancel" OnClick="@CloseDialog" /> 

        </DialogButtons> 

    </SfDialog> 

    <SfGantt ID="GanttExport" @ref="Gantt" TValue="Table" Height="450px" Width="700px" 

             …// 

    </SfGantt> 

 

@code {  

    public string Name { get; set; } 

    public string Id { get; set; } 

    private bool IsVisible { get; set; } = false; 

 

    public void OnActionBegin(ActionBeginArgs<Table> args) 

    { 

        if (args.RequestType == "beforeOpenEditDialog" || args.RequestType == "beforeOpenAddDialog") 

        { 

            args.Cancel = true; 

            RenderDialog(args.RowData.TaskData); //Pass selected data 

        } 

    } 

    public void RenderDialog(Table data) 

    { 

        Id = data.Id.ToString(); // Render Id textbox with id value of selected data 

        Name = data.Name; //Render Name textbox with Name value of selected data 

        this.Dialog.Show(); 

    } 

 

    private void CloseDialog() 

    { 

        this.Dialog.Hide(); 

    } 

 

 

    private void OkDialog() 

    { 

 

        this.Gantt.UpdateRecordByID(new Table() { Id=Convert.ToInt16(this.InputId.Value), Name=this.InputName.Value}); // Update record using method 

        this.Dialog.Hide(); 

    } 

 

    public SfGantt<Table> Gantt; 

    public SfDialog Dialog; 

    public SfTextBox InputName; 

    public SfTextBox InputId; 

} 

 

We have prepared sample for this. Please find it from below sample link.

Hi !

Do we have option to fully refresh Gantt view from datasource based on current datasource state (not only by

UpdateRecordByID).

Assume scenario:

1. Datasource - ExpandoObject column list (TValue = "ExpandoObject")
2. Action changes datarecords (ChildDrag, Leftresising, RightResizing, ParentDrag, ProgressResizing, changing Cell etc..)
3. OnActionComplete I modify Datasource records - and anything can be changed in source List<ExpandoObject>.
4. I would like to refresh Gantt View and expecting RefreshAsync() to do this but nothing happens. So I get Gantt view not synchronized with original source data..

Does it really only one option exist ? - Find modified records and iterate through by UpdateRecordByID to get data integrity ?
