Default style for GridViewCheckBox

[Edward]

I changed my Checkbox to display a ? instead of - when the value is null by changing the IndeterminateIcon from a rectangle to a path that resemble a "?".  Can you provide the default style for the GridViewCheckBox so I can do the same?

Hello Edward,

 

You may change this by altering the appearance of GridViewCheckBox and replace the indeterminate icon with a TextBlock, which Text property is set to "?", please refer to the attached picture. 
If you need any further assistance do not hesitate to contact us!

Best wishes,

I made the change and while the ? is showing up, once I switch to edit mode then it defaults back to the -.  Is there a EditTemplate somewhere?

Hi Edward,

 

When GridViewCheckBoxColumn goes into edit mode the standard CheckBox appears. If you want to maintain the same behavior in edit mode you should change the Indeterminate icon for CheckBox control in the same way and apply it within GridViewCheckBoxColumn's EditorStyle, as shown below:

<Style x:Key="style1" TargetType="CheckBox">
.....The rest of your style
</Style>

<telerik:GridViewCheckBoxColumn EditorStyle="{StaticResource style1}" ... />

You may also mark this style as an implicit without specifying the x:Key attribute and it will be applied to all CheckBox in your current application.

I already have a implicit checkbox style defined, using the ? instead of -.  However, the checkbox inside the grid still use -, where the checkbox outside of the grid use ?.

In fact, I don't think the checkbox in edit mode is the same as the regular checkbox at all.  The default checkbox in grid edit mode has 2 borders (so the tick in it is smaller), while the normal checkbox only have 1 border.

Hello Edward,

 

The CheckBox control is one of the native Silverlight controls supported by our theming mechanism.
As you might know we ship our themes as separate projects. You may get the xaml files for any Telerik theme from the Themes folder of your personal installation. May you please open the Themes/Office_Black folder, find the CheckBox.xaml file. Copy this style to your current project change the Indeterminate icon to "?", mark this style as an implict and let me know what happens.

I already have a style for checkbox using the ?, defined as implicit in one of my resource dictionary file.  That style is working fine outside of the grid.  I saw that file, but it is largely a duplicate of my own and it is just another implicit style.  

I am guessing the implicit style stored under the theme is overriding my own implicit style.  If that's true then I need to edit then recompile all the themes myself?

[Vanya Pavlova]

Hi Edward,

 

Indeed the styles are theme specific and they use their own resources for a particular theme. In each theme you have a separate styles for a control and its parts. For example: if you want to change the CheckBox in Windows7Theme you may copy only the style for this control in Windows7 theme to your current project and modify in in a desired way. Then the changes will be reflected correspondingly.  


Please let me know if you need a sample project that demonstrates this approach.

I said I already have a working implicit style with my checkbox.  But anyways, I removed my own working copy, then copy the one from OfficeBlack to my project and modified it there.

At the end, nothings change:  checkbox outside of the grid reflects the changes; checkbox inside the grid does not.

Hello Edward,

 

I have prepared an example for you using binaries as part of our latest internal build that demonstrates how this can be achieved.
