Hi Ajay, 

 

Thank you for contacting Syncfusion support. 

 

Based on the provided information, we understand that your requirement is show the expand / collapse icon after customizing the caption summary row in DataGrid Xamarin.Forms. If you customized using Template expand / collapse icon won’t be visible since applied template for the entire row. If you mentioned, customizing as applying style / customizing the caption summary text expand / collapse icon will be visible. For enabling expand / collapse icon, you need to set AllowGroupExpandCollapse property of DataGrid as true. 

 

We have checked the same and it is working fine as expected.

Please check and let us know if you have any query.

Hi,

Here i made "AllowGroupExpandCollapse"  as true. and here i used custom caption summary template which includes check box, label and icon.so when i customize it, i could not able to see the expand/collapse icon. Please check once the below images.

in this case i could not find the icons. your sample project is not related like this.

We have checked your requirement based on the last update "Need to display Expand and Collapse Icon even when we define the caption summary template." We have defined the caption summary template based on the shared screen shot and the Expand and Collapse icon is rendered in the caption summary row at our end.  

 

In the following link, we have attached the tested sample for your reference,

Hi Ajay, 

 

Sorry for the inconvenience caused. 

 

We have checked the reported issue in the last update and able to see Expand collapse icon is static not responding to the Expand and collapse action in the shared sample. But You have mentioned that Expand and collapse icon is not rendered if we define Caption summary template in your application.  

 

Regarding the static rendering of expand and collapse we will validate and update you further details in two business days (May 31, 2019). We appreciate your patience until then.

 okay , And one more requirement is...

When tap on group ,it is going to expand. again tap on the group,now it is going to collapse. Here , each group contains more than 100 records. due to huge records when i tap on the group, for expand (to show the records)  it takes some time.so here i need to show the indicator to user something is going like that.

Thank You

Ajay

Hi Ajay, 

  

Your requirement to load an indicator while expanding the groups can be achieved by using SfBusyIndicator. We had customized the SfBusyIndicator visibility in the Group expanding event. So that while expanding SfBusyIndicator is loaded. 

  

Refer the below code for reference 

  

public partial class MainPage : ContentPage 

{ 

    SfBusyIndicator indicator; 

    public MainPage() 

    { 

        InitializeComponent(); 

        indicator = new SfBusyIndicator(); 

        dataGrid.GroupExpanding += DataGrid_GroupExpanding;            

    }    

   

    private async void DataGrid_GroupExpanding(object sender, GroupChangingEventArgs e) 

    { 

        //// customize based on the requirement.            

        indicator.IsBusy = true; 

        indicator.IsVisible = true; 

        indicator.AnimationType = AnimationTypes.SlicedCircle; 

        grid.Children.Add(indicator); 

        await Task.Delay(200);             

        indicator.IsBusy = false; 

        indicator.IsVisible = false; 

    } 

}   

  

We had prepared a sample based your requirement and you can download it from the below link.

And we are analyzing the issue “Expand and collapse icon is not visible when we define the caption summary template”. We will update you with further details on 07^th June 2019.
