ASPxGridView - How to use the CommandButtonInitialize event and get row values

created 13 years ago

Hello DevExpress,
I have a question which was discussed some times, but I got no answer so far which is practical.
In an ASPxGridView I need to hide the delete and edit command buttons conditionally.
In some examples you recommend the CommandButtonInitialze event.
There are several examples which demonstrate to handle the buttons visibility on oddRow condition.

But this is not practical for me, as I need to set the condition on a fields value in the particular gridrow.
For example: in my grid I have a column "processed". In all rows where Processed is true, I want hide the commanbutton,
when false the show it.
My question: How can I get the value of the column in the row inside the CommandButtonInitialize Event?
Thank you
Regards
Juergen

Hello Juergen,
Thank you for contacting us.

Absolutely. Please use the E3028 - ASPxGridView - How to specify the CommandButtons’ and Custom CommandButtons’ properties based on any custom criteria Code Central example as a starting point.
It illustrates how to accomplish this task based on a particular DataRow's values:

C#
protected void ASPxGridViewInstance_CommandButtonInitialize(object sender, ASPxGridViewCommandButtonEventArgs e) {  
    e.Visible = CommandButtonVisibleCriteria((ASPxGridView)sender, e.VisibleIndex);  
}  

private bool CommandButtonVisibleCriteria(ASPxGridView grid, int visibleIndex) {  
    if (visibleIndex == -1) return false;  

    bool processedValue = Convert.ToBoolean(grid.GetRowValues(visibleIndex, "processed"));  
    return processedValue == true;  
}

Thanks,
Mike
