Using the highlightedCssClass property on a dock zone is great. However, I can't seem to find out how to set the css class when a dock is hovered over a forbidden zone, so I can highlight to indicate that the dock cannot go in that zone.

Any help?

I can not make a GridNumericColumn readonly !

Hi,

In a page a have combobox and a rad grid.

According to the selected value of combobox,
1-) I am making GridNumericColumn (say Col1) of my radgrid visible = false. (In NeedDataSource method -server side..-)
2-) I am making that GridNumericColumn (Col1) readonly as well. (In NeedDataSource or OnItemCommand method -again on the server side..-)

When I am inserting an item to grid, everything works fine.. (Since it is readonly and hidden, I will not be entering any data to that column.. ) So that column will be updated to database as NULL, which is fine..

But when I am editing the row I just entered, I am getting 'Object reference not set to an instance of an object.' exception..

If I remove the code which makes Col1 readonly, I am not getting this exception.. But I need that Col1 readonly, because I do not want user to enter any data to that column..

What should I do??

Colorize results in very dark skin

Hi,

I'm trying out the visual style builder and am having some problems with the "Colorize" option. Some of the standard colors (e.g. #00ff00) in the color chooser work as I would expect (leaving the "background" color as a "white/light" color, with the new color being applied to the control elements) while others (e.g. #00cc99) result in a very dark-looking control. Also, all of my custom corporate colors I am trying to use generate very dark controls when using the "colorize" option, even if I use a very light color:

100% #006A72

75% #33878f

50% #71a8ae

25% #b0ced3

10% #ddeaec

Also, the "start over" option does not appear to reset the changes I've made as it looks like any changes that are made are stacked up on top of each other regardless of whether you click on the or not.

I'm using the Web20 skin as a template.

Can you please tell me how I can easily generate a nice skin using my custom coroprate colors using the style builder? Am I doing something wrong here?

Thanks..

RadTreeView in RadCombo with Dynamic Data

I am using 2 RadComboBox controls (Region & Country). The Country drop-down is populated dynamically when user selects a Region in the Items_Requested event. I need to create a RadTreeView control which will have a Country Name and list locations for each country. How could this be implemented? I am getting script not registered Javascript error.

Thanks in advance.
