Setting image in list control item

I want to set image only in particular rows of listctrl.

If I use CListCtrl's SetImageList, it is setting image in first column of each row.

Is it possible to set image only in whichever row I want.

A simple way to achieve it is adding a transparent image in your CImageList and set it on the list item you don't want the image to appear.

I think it's a little bit messy but it works for me.

If your CListCtrl has LVS_OWNERDRAWFIXED style, than you can decide which column which image will have. For this purpose you need to set extended style LVS_EX_SUBITEMIMAGES for your list after it will be created. Than you add CImageList field to your CListCtrl-derived class, for example it will have m_imgList name. This field has to be initialized with default values and with image resource that will be using. After that you have to call SetImageList and pass it m_imgList. As long as your list will have LVS_OWNERDRAWFIXED style you need to implement DrawItem function in which you will call something like this for image drawing:

LVITEM lvItem   = {0};
lvItem.mask     = LVIF_IMAGE;
lvItem.iSubItem = nCol;         // column index
lvItem.iItem    = nItem;        // item index 

GetItem(&lvItem);

POINT p;    // init it like you want
pDC         // pointer on device context

m_imgList.Draw(pDC, lvItem.iImage, p, ILD_MASK);

And before that, when you will fill the list with values, you have to fill in LVITEM structure for needed column:

LVITEM lvItem   = {0};
lvItem.iItem    = nItem;    // item index
lvItem.iSubItem = i;        // column index
lvItem.iImage   = nImg;     // image index from imageList
lvItem.mask     = LVIF_IMAGE;

And after that you have to call InsertItem or SetItem with this lvItem parameter.
