Hello.

I've made a progress bar column like it's explained in your documentation: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/creating-custom-cells

Protected Overrides Sub SetContentCore(ByVal value As Object)

If Me.Value IsNot Nothing AndAlso Me.Value IsNot DBNull.Value Then

Me.radProgressBarElement.Value1 = Convert.ToInt16(Me.Value)

End If

End Sub

 

how can i set the value2 of the progressbar?

and i'd like could modify the maximum value.

i've found:

 

protected override void CreateChildElements()
{
    base.CreateChildElements();

    radProgressBarElement = new RadProgressBarElement();
    radProgressBarElement.Minimum = 0;
    radProgressBarElement.Maximum = 10;
    this.Children.Add(radProgressBarElement);
}

 

but in this case the maximum it's diferent in each row of the grid (it is defined by an other field -column- )

 

would be it possible??

 

thx very mucht

Hello, Jose,    

Note that the CreateChildElements method is fired just once for the cell element when creating. Due to the UI virtualization in RadGridView, cell elements are created only for currently visible cells and are being reused during operations like scrolling, filtering, grouping and so on. The appropriate place to synchronize the value of the progress bar with the value of the cell is the SetContentCore method. Thus, you can access the data row to which the cell element is currently associated and determine what settings to apply to the RadProgressBarElement, e.g. Maximum

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Thx for your Answer.

I don't understand how to pass two different values to the setcontentcore, for example value1 and maximum of the progressbar.

Hello, Jose,    

Following the help article for creating custom cells in RadGridView, I have prepared a sample project for your reference, where in the SetContentCore method, a different maximum is specified for the RadProgressBarElement

            protected override void SetContentCore(object value)
            {
                if (this.Value != null && this.Value != DBNull.Value)
                {
                    if (this.RowIndex % 2 == 0)
                    {
                        this.radProgressBarElement.Maximum = 100;
                    }
                    else
                    {
                        this.radProgressBarElement.Maximum = 50;
                    }
                    this.radProgressBarElement.Value1 = Convert.ToInt16(this.Value);
                }
            }

The following screenshot demonstrates how the cells illustrates the same value with the different maximum:
