    I have a RadGridView that has data bound to it.  One of the fields is a bool field type.  What I want to happen, is if the user changes that value, I want the forecolor of the entire row to change.  So, in my RowFormatting, I have to code to change the forecolor, and this works, only after I move the record pointer or selected a different cell in the same row.  How can I get the row to change color as soon as I change the cell's value?

     

    TIA

    Hi Mark,

    This is because the value is changed after the cell is changed. You can set the EditMode of the checkbox column to fix this:
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        var col = radGridView1.Columns[0] as GridViewCheckBoxColumn;
        col.EditMode = EditMode.OnValueChange;
    }

    I hope this will be useful. Let me know if you have additional questions.

    This was what I was exactly looking for, I just could not find it.

     

    Thanks for the help.

    I do have one other question, I was trying to do this similarly to a GridViewTextBoxColumn, but I don't see editmode property there. What are the properties I would need to update to do the same for other editor control columns to do the same as the CheckBoxColumn?

    Hello Mark,

    There is no such property for the other editors. The checkbox is a permanent editor that is visible at all times, the other editors are only visible when the user is editing the cell. However, you can use ValueChanged event instead of CellValueChenged. This event will be fired after the value in the editor is changed. 

    Should you have any other questions do not hesitate to ask.

    Well, this poses a problem then, as I am subscribing to the bound data's PropertyChanged event and not any event on the grid or its children.  Your proposal would have me subscribe to column's ValueChanged event for columns that I want to be Read/Write, which is inefficient, also would not work, as in the RowFormatting of the grid, I am looking again, at the bound data's values to determine if I am formatting the row or not, the Value of the cell doesn't affect the bound data until Validated.

    Hi Mark,

    The data-bound value will be changed when the user leaves the cell and this will trigger the PropertyChanged event. There is no way to change it after each keystroke. What is the code that you are currently using to format the rows?

    I have attached a small project that shows how you can use the ValueChanged event to format the row. I am using the Tag property to determine which row should be styled.

    I am looking forward to your reply.
