Dear Support,

I have a grid when each row have a number cell header on the left side.

I want that the row, or the first editable cell in the row will be selected when the number cell is pressed. Cuurently when I hover over the number cell, the cursor changes to a left pointing arrow, and clicks are ignored.

This is how I initialize this cell:

    CExtGridCellHeader* pCellHeader = (CExtGridCellHeader*)GridCellGetOuterAtLeft(0, nRowCountIndex, RUNTIME_CLASS(CExtGridCellHeader));
    
    if (NULL==pCellHeader)
    {
        return -1;
    }

    pCellHeader->ModifyStyle(
        __EGCS_HDR_FOCUS_ARROW_RESERVE_SPACE|
        __EGCS_HDR_FOCUS_ARROW_DISPLAY|
        __EGCS_HDR_ROW_COLUMN_NUMBER|
        __EGCS_TA_HORZ_RIGHT);

A click on a header cell can be used for sorting rows/columns or selecting them. We thing you should simply apply the __EGBS_SF_SELECT_OUTER_ROWS style with the grid’s SiwModifyStyle() method.

I have this flag set, and still, when clicking the row header cell nothing happens. I sort my rows by clicking the column headers, I don’t need to sort columns, the row header is used to give each row a serial number to identify the rows, so I would like it that when the number is pressed, the first cell in the row will be selected.

Please compare how you initializes your grid window with how it is done in the Order Details grid in the SimpleGrids sample. The grid sorts rows when a header cell at top is clicked. It selects rows when a header cell on left is clicked. Unfortunately, it’s not possible to select
only grid cells in the first column when a header cell on left/right is clicked. You should override the CExtGridBaseWnd::OnGbwAnalyzeCellMouseClickEvent() virtual method to determine which header cell was clicked and select appropriate cell areas using the CExtGridBaseWnd::SelectionSet() method.
