Draggable in Predefined Dialogs

4 Nov 20254 minutes to read

Predefined dialogs support dragging by the dialog header, allowing users to reposition the dialog within its target container. Enable this behavior using the DialogOptions.AllowDragging property. The default value is false. Dragging requires a visible header; if the header is hidden or replaced, dragging behavior may be affected.

The following examples demonstrate enabling dragging for Alert, Confirm, and Prompt dialogs.

alert.razor

@using Syncfusion.Blazor.Popups
@using Syncfusion.Blazor.Buttons
@inject SfDialogService DialogService
    <div>
        <SfButton @onclick="@AlertBtn">Alert</SfButton>
    </div>
@code {
    private async Task AlertBtn()
    {
        await DialogService.AlertAsync("10% of battery remaining", "Low Battery", new DialogOptions()
            {
                AllowDragging = true,
            });
        }    
}

confirm.razor

@using Syncfusion.Blazor.Popups
@using Syncfusion.Blazor.Buttons
@inject SfDialogService DialogService
    <div>
        <SfButton @onclick="@ConfirmBtn">Confirm</SfButton>
    </div>
@code {
        private async Task ConfirmBtn()
        {
            bool isConfirm = await DialogService.ConfirmAsync("Are you sure you want to permanently delete these items?", "Delete Multiple Items", new DialogOptions()
            {
                 AllowDragging = true,
            });
    }
}

prompt.razor

@using Syncfusion.Blazor.Popups
@using Syncfusion.Blazor.Buttons
@inject SfDialogService DialogService
    <div>
        <SfButton @onclick="@PromptBtn">Prompt</SfButton>
    </div>
@code {
    private async Task PromptBtn()
    {
        string promptText = await DialogService.PromptAsync(null, "Join Wi-Fi network", new DialogOptions()
        {
            AllowDragging = true,
            ChildContent = @<table class="Table">
                    <tbody>
                        <tr>
                            <td>SSID:</td>
                        </tr>
                        <tr>
                            <td><b>AndroidAP</b></td>
                        </tr>
                        <tr>
                            <td>Password:</td>
                        </tr>
                        <tr>
                            <td>
                                <span class="e-input-group">
                                    <input type="password" id="password" name="Required" class="e-input">
                                </span>
                            </td>
                        </tr>
                    </tbody>
                </table>
        });
    }
}
