I'm attempting to load default chart settings from an xml file like this:-

RadChart chart = new RadChart();
chart.LoadFromXml (filename)

But the default size of chart (400px x 300px) seems to get used despite the fact that my xml starts like this :-

<RadChart Location="0, 0" Size="300, 200" TabIndex="0">

Why is this? Is it a bug? Are there any other items that cannot be set from the xml file?

RadGridView GridViewCheckBoxColumn bug?

hi there,

I've noticed some odd behaviour with a RadGridView in a project of mine-

Basically the grid is built at runtime as the data is provided by a stored proc that can vary the number of rows/columns depending on parameters.

As such, to correctly create a checkboxcolumn for "bit" type data, on Databind, I locate columns with bit data and instantiate GridViewCheckBoxColumns to replace them. This works as expected and populates the checkboxes appropriately, so so far so happy.

The odd thing I noticed after implementing various bits of logic on the ValueChanged ValueChanging cell, and while fiddling around with right-clicking on the grid (context menus etc) was that if you right click on the checkbox cell, a context menu appears as expected, but if you right click on the actual check-box element, sometimes the check toggles, but most mysteriously without firing the ValueChanged or ValueChanging event... !

I'm pretty sure it's not something I've done, so may be worth investigating?

I unfortunately don't yet know enough about C# or your internal object structure to be able to work around this particular issue

Regards,

MIke Renwick

HierachicalListView with expandable usercontrol rows


Hi,
I want to build a control which has the following capabilities.
1. ListView like columns, with image buttons (to expand)
2. A row will expand to show another control (details)
3. The ListView should be hierarchical
Sorry for my poor ASCII art, consider it a christmas laugh : )
> Col1        Col2          +
    > Col1    Col2          -
	___________________________________
	|Some user control with charts etc|
	|_________________________________|
> Col1        Col2          -
	___________________________________
	|Some user control with charts etc|
	|_________________________________|
> Col1        Col2          +
What would you recommend? I thought of using the Grid.
But, at least in Q2, I couldn't add my tailor made user 
controls as rows.

Thanks, happy christmas holidays!

Column layout changes when rebinding in 2009 Q1

Hi!

Today I uppgraded to Q1 2009 (from Q3 2008)

Before I upgraded all my grids were working fine but after the upgrade my grid layouts changes after I rebind the grid.
Am I missing something or is this a bug?

Heres what happens:
1) I have a rad grid that is connected to a datasource
2) I open the rad grids property builder and select visible=false on the 2 first columns in the list
3) I press OK, now the 2 first columns are not visible in the VS IDE
4) I run the program and the 2 first columns are still hiden, perfect
5) I now press a button that binds the datasource to a list of object
6) What happens now is that every settings that I made in the property builder is gone and all columns in my objects are displayed!!!

It's like it do a "auto create columns"

Please tell me that im missing something..

Regards

Change background color

Hi,

I would like to change the background color of a bottom using visual style builder.

In control structure, I go to the path: RootRadElement/RadButtonElement/ImageAndTextLayoutPanel/ImagePrimitive. Here, in Appeareance (the properties on the right of the window) in "Image" property I want to set an image but is not allowing me to even choose an image.

How could I do this?

Thank you.

PD I edit my post because the title of a thread is "Change background IMAGE" and not color.

A regex validating textbox

Hi!

How about extending the textbox by adding a "RegularExpressionValidation" property to it.
In this field I can add a regular expression that I want the control to validate against when validation occurs :)

Using this new control with a errorprovider and I get a very easy input box that I can customize so the input text is just as I want it :)
