Hi ..how to acsess the control  like textbox, label inside the radgridview  by clicking the button outside

[Ivan Ivanov]

Hello,

You can find it by traversing the visual tree with the WPF VisualTreeHelper, or with our extension method ChildrenOfType<FrameworkElement> (which is acually much easier to use). Can you please share which would be the ultimate goal of this activity? Generally, setting visual properties, or executing custom event logic for the cell elements is not recommended, as this can cause unexpected results when the UI virtualization logic is enabled.

hi.. what is equivqlent event of itemdatabound in wpf grid

Hi ..how to refresh the xaml page using vb.net

[Ivan Ivanov]

Hi,

I will try to address the listed inquiries in their original order. If you need any additional help, related to our controls, in the future, I would ask you to open a separate thread for every new question.

1. Looking through the provided XAML snippet, I am not sure which element do you want to access. However, you can always use our method ChildrenOfType<FrameworkElement> (that I mentioned in my first post) and find it by name.
2. You can use the RegularExpression attribute, to validate the input in the model.
3. You have an empty editor, as soon as you start editing, am I right? Can you please verify that the TextBox is properly bound? You can also check for binding expression path errors in the output window.
4. You can try the DataLoaded event.
