Hi,

I want to increase the height of the combobox control.Increasing the width of the combobox control is happening but when I am trying to increase the height of the control I am not able to drag it downwards.

I googled for long time and I did not find any answer, everywhere they are mentioning how to increase the height of the combo text but not the control height.

Can anyone please let me know how can I increase the height of the combobox control.

Thanks in advance,
Raja

Which height do you mean (the height of the edit/static field or for the dropdown area) and how do you want to set the height (programmatically or with the resource editor)?

To change the visual height, you need to make it OwnerDrawn and implement MeasureItem() function like:

void MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
lpMeasureItemStruct->itemHeight = 17;
}

Here is a good example:
IconComboBox - Selecting Icons[^]

Solution 1

The C++'s SetItemHeight example from MSDN:

C++

// Set the height of every item to be the 
// vertical size of the item's text extent.
CString str;
CSize   sz;
CDC*    pDC = m_pComboBox->GetDC();
for (int i = 0; i < m_pComboBox->GetCount(); i++)
{
   m_pComboBox->GetLBText(i, str);
   sz = pDC->GetTextExtent(str);

   m_pComboBox->SetItemHeight(i, sz.cy);
}
m_pComboBox->ReleaseDC(pDC);

Good luck,
Herb

Thanks for your reply.I have also done the same thing.After doing as above the size got increased(vertical height).But the text is not at the centre.It is exactly at the top.Normally if we take a standard combo box the text in the control seems to aligned correctly.Now,when I increased the height the text remains in the same position. Doesn't it move down when we increase the height(I mean to be aligned correctly).Can you please let me know how can get this done.
