i'd like to display two values with the Telerik WinForm Progress bar; one value being the progress of a single action, and the second being the progress of all actions. For example, we're sending 5 emails, and performing an operation on each...one value is the progress of the operation of the individual email and the second is the overall progress.

Is this possible? Is there sample code available? I've looked at the documentation and demo app, but need more info.

Thanks in advance,

Gene

hello Tim,

I've prepared a small sample for you (just a RadProgressbar on a form) which sets the value1 for each of 4 tasks, and value 2 to be the overall progress.

Hope this helps but let me know if you have any questions.

Thank you Richard,

I created a new VB project and pasted your code in after adding the Telerik Progress bar, but when I run it I only see a single progess value (no lighter or darker shade). Is there a property that I need to set on the control?

Regards

Hello,

No, there's nothing else to set, but to be fair, the Value2 is not that easy to see on the default theme. Set the background colour of the FillPrimitive to white to see it a little better. Please can you add this to the end of the load event and you'll see it.

Dim prim As Telerik.WinControls.Primitives.FillPrimitive = CType(Me.RadProgressBar1.ProgressBarElement.Children(0), Telerik.WinControls.Primitives.FillPrimitive)
prim.BackColor = Color.White
prim.GradientStyle = GradientStyles.Solid

Let me know if you need more help

Richard,

Ah...Thank you very much- that was the issue. A '"ittle hard to see?"- thats an understatement! With the white background its a 'little hard to see'! I expect I have to create a custom theme to change the secondary color? I'm new to Telerik controls, so any documentation you could point me to would be appreciated- I lost a day just because I couldnt see value2 changing.

Regards

Hi Tim,

I'd suggest making your own theme for the radProgressBar if you intend to use a lot of them. Have a look at this link about the Visual Style Builder.

If you just want to change one or two colours on one RadProgressBar, then let me know what colours you want to change and I'll point you in the right direction.

Regards,
Richard

Thanks so much Richard,

I haven't used the Visual Style Builder yet so your help is greatly appreciated. For now I'd like to just use two shades of Blue,  a medium and a darker blue for the progress indicator values. Visual Style Builder looks pretty good, but for now I need to show it working. The default Green and very light gray obviously doesnt work for me.

You're welcome Tim,
may I ask that you mark as answer all suggestions that you find have helped.

There may be a quick way, but I'm not sure how well this would suit your requirements.
1: Drop a BreezeExtended theme onto the form from the toolbox
2: Change the ThemeName of the radProgressbar to BreezeExtended
3: Maintain the white back colour.

have a look and let me know if that's ok.

Here you go Tim,

This should be better.
Me.RadProgressBar1.ThemeName = "BreezeExtended"
Dim prim As Telerik.WinControls.Primitives.FillPrimitive = CType(Me.RadProgressBar1.ProgressBarElement.Children(0), Telerik.WinControls.Primitives.FillPrimitive)
prim.BackColor = Color.White
prim.GradientStyle = GradientStyles.Solid
Dim progressBarPrim As Telerik.WinControls.Primitives.ProgressBarPrimitive = CType(Me.RadProgressBar1.ProgressBarElement.Children(1), Telerik.WinControls.Primitives.ProgressBarPrimitive)
progressBarPrim.BackColor = Color.Blue
progressBarPrim.BackColor2 = Color.Blue
progressBarPrim.GradientStyle = GradientStyles.Solid

Richard,

The darker blue is great, but the light blue is still much too light.

Richard,

Thats much better. A shame to have lost the highlighting on the value1 progress, but I assume I can restore that by working with the visual Style builder. Thanks again,

Tim

to get the linear look back set
Dim progressBarPrim As Telerik.WinControls.Primitives.ProgressBarPrimitive = CType(Me.RadProgressBar1.ProgressBarElement.Children(1), Telerik.WinControls.Primitives.ProgressBarPrimitive)
progressBarPrim.BackColor = Color.Blue
progressBarPrim.BackColor2 = Color.Blue
progressBarPrim.GradientStyle = GradientStyles.Linear

Thats great. The odd thing is the 'highlight' lighter shade on the value1 bar is now on the bottom of the bar. But you've shown me plenty- I'm sure I can sort the rest. Much appreciated.
