Question

Due to fact that I load data from a database and place it into a DevExpress TextEdit control on FormLoad, the event handler TextEdit_EditValueChanged is called. Is it possible to make any checking in the event handler, or prevent the event from being raised?

Answer 1

Something like this:

bool dataLoaded = false;

private void LoadData()
{
    // do the loading and set the Text property of the textEdit
    dataLoaded = true;
}

private void TextEdit_EditValueChanged(object sender, EventArgs e)
{
    if (dataLoaded == false) return;
    // the code after this comment will run only after the data was loaded
}

Or you can add the event handler after the loading was done, like this:

private void LoadData()
{
    // do the loading and set the Text property of the textEdit
    TextEdit.EditValueChanged += TextEdit_EditValueChanged;
}

private void TextEdit_EditValueChanged(object sender, EventArgs e)
{
    // the code after this comment will run only after the data was loaded
}
