Introduction

Gets or sets the text to display in the empty data row rendered when a DataGridView control is bound to a data source that does not contain any records 

Background 

The empty data row is displayed in a ASP.Net GridView control when the data source that is bound to the control does not contain any records. Use the EmptyDataText property to specify the text to display in the empty data row using EmptyDataRowStyle in ASP.Net. But this is not in Windows Form Application, so i have created a Component for this functionality.    

Using the code 

Following screen is display properties of EmptyDataText Grid component.

Binding grid with 0 records:

After binding grid it looks like:

Following code is self explanatory.
Following code that have been written in Component\DataGrid.cs In DataGrid.cs i have Overrides Pint method of DataGridView.

Points of Interest

Now I will try to support automatic label display instead of checking following lines of code. 

//You should use only following 5 lines of code.
            dgEmptyData.DataSource = dt;
            if (dt != null && dt.Rows.Count > 0)
                //Remove text when records exists
                dgEmptyData.EmptyDataText = "";
            else
                //Assign text when no record found
                dgEmptyData.EmptyDataText = txtEmptyText.Text;
