[Solved] - Can i show busy circle while load file or data?

[The GridLock]

Hi,

When I use combobox to select a table from database, it will take some time to wait, I want to prevent users from manipulating it during this time!

Can I do something similar to datagrid?

Thanks you!

Hi GridLock, 

Thank you for using Syncfusion controls. 

You can use the SfDataGrid.ShowBusyIndicator property to show the busyindicator while loading the data.

Hi Susmitha,

I have a few datagrid and a few combobox on winform (not just one),

My idea is that while loading the file (data), there will be an animation in the middle of the form. I was thinking of a datagrid match, but it took me a few more steps to show the table in the datagrid so if the show was busy circle right away it wouldn't be appropriate. Should I use the progressbar?

Hi khanh dang, 

 

You can load the BusyIndicator for Form. Please check the below code, 

 

public partial class Form1 : Form 

{ 

    BusyIndicator busyIndicator = new BusyIndicator(); 

    Timer timer = new Timer(); 

    public Form1() 

    { 

        InitializeComponent(); 

        timer.Tick += Timer_Tick; 

    } 

 

    private void sfButton1_Click(object sender, EventArgs e) 

    { 

        timer.Enabled = true; 

        busyIndicator.Show(this); 

        timer.Start(); 

        timer.Interval=10000; 

        this.sfButton1.Text = string.Empty; 

    } 

 

 

    private void Timer_Tick(object sender, EventArgs e) 

    { 

        busyIndicator.Hide(); 

 

    } 

 

} 

 

Here, we just show busy Indicator in certain time interval. You can use this based on your requirement. 

 

If you use the ProgressBar, you need to change the value of progressbar in the interval of loading.
