To restrict the CheckBox checking capability in Blazor, you can handle the ValueChanged
event and check whether the CheckBox should be allowed to change its value. Here's an example:
bool canCheck
property in your component, which will determine whether the CheckBox can be checked or not:public bool canCheck = true;
ValueChanged
event:<input type="checkbox" @bind="isChecked" @onchange="OnCheckedChanged" disabled="@(!canCheck)" />
@code {
bool isChecked;
void OnCheckedChanged(ChangeEventArgs e)
{
if (!canCheck)
{
isChecked = false;
}
else
{
isChecked = (bool)e.Value;
}
}
}
OnCheckedChanged
method, check whether canCheck
is true or false. If it's false, set the isChecked
value to false as well.void OnCheckedChanged(ChangeEventArgs e)
{
if (!canCheck)
{
isChecked = false;
}
else
{
isChecked = (bool)e.Value;
}
}
canCheck
property to false whenever you want to disable the CheckBox's checking capability:public void DisableChecking()
{
canCheck = false;
}
With this approach, you can easily control whether the CheckBox can be checked or not in your Blazor component.
