因此，您可以将各种字段绑定到class HeaderColorChanger implements ViewPager.OnPageChangeListener {
private ArgbEvaluator argbEvaluator = new ArgbEvaluator();
private View mView;
private int[] mColors;
HeaderColorChanger(View view, int[] colors) {
mView = view;
mColors = colors;
}
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
mView.setBackgroundColor(getHeaderColor(position, positionOffset));
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
private int getHeaderColor(int position, float positionOffset) {
if (position == mColors.length - 1) {
return mColors[position];
}
int startColor = mColors[position];
int endColor = mColors[position + 1];
int color = (int) argbEvaluator.evaluate(positionOffset, startColor, endColor);
return color;
}
}
，这样ComboBox的选定值就会自动填充文本字段。
ComboBox 您可以对var SID = Convert.ToInt32(cbosSID.Text);
using (Entities2 db = new Entities2())
{
var student = (from a in db.Students where a.SID == SID select a).First();
txtsFName.Text = student.FName;
txtsLName.Text = student.LName;
txtsPhone.Text = student.Phone;
txtsAdd1.Text = student.Add1;
txtsAdd2.Text = student.Add2;
txtsState.Text = student.State;
txtsSuburb.Text = student.Suburb;
txtsPost.Text = student.Postcode;
dteDOB.Value = student.DOB;
dteStart.Value = student.SDate;
}
的各个列做同样的事情吗？
我已在DataGridView，学生ID和标记中添加了两列。我尝试使用DataGridView进行此操作，但这并不起作用。
editDataGridView.Columns[course.SID].DataPropertyName = "clmSID";
