How to access a gridview column on rowdatabound ?


I would like to change the value of my gridview column to active when the value is 1. I have gridview column like

<asp:BoundField   DataField="STATUS" HeaderText="STATUS" SortExpression="STATUS" HeaderStyle-HorizontalAlign="Left">
                <HeaderStyle HorizontalAlign="Left"></HeaderStyle>
            </asp:BoundField>

and cs code

 protected void gvCategory_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.Cells[5].Text=="0")
            {
                e.Row.Cells[5].Text = "INACTIVE";
            }
        }
    }

This is working but it would fail if i change the column order. What i need is something like findControl function. Thanks.


Solution

  • Here's a few utilities I wrote years ago that may help you:

    // ---- GetCellByName ----------------------------------
    //
    // pass in a GridViewRow and a database column name 
    // returns a DataControlFieldCell or null
    
    static public DataControlFieldCell GetCellByName(GridViewRow Row, String CellName)
    {
        foreach (DataControlFieldCell Cell in Row.Cells)
        {
            if (Cell.ContainingField.ToString() == CellName)
                return Cell;
        }
        return null;
    }
    
    // ---- GetColumnIndexByHeaderText ----------------------------------
    //
    // pass in a GridView and a Column's Header Text
    // returns index of the column if found 
    // returns -1 if not found 
    
    static public int GetColumnIndexByHeaderText(GridView aGridView, String ColumnText)
    {
        TableCell Cell;
        for (int Index = 0; Index < aGridView.HeaderRow.Cells.Count; Index++)
        {
            Cell = aGridView.HeaderRow.Cells[Index];
            if (Cell.Text.ToString() == ColumnText)
                return Index;
        }
        return -1;
    }
    
    // ---- GetColumnIndexByDBName ----------------------------------
    //
    // pass in a GridView and a database field name
    // returns index of the bound column if found 
    // returns -1 if not found 
    
    static public int GetColumnIndexByDBName(GridView aGridView, String ColumnText)
    {
        System.Web.UI.WebControls.BoundField DataColumn;
    
        for (int Index = 0; Index < aGridView.Columns.Count; Index++)
        {
            DataColumn = aGridView.Columns[Index] as System.Web.UI.WebControls.BoundField;
    
            if (DataColumn != null)
            {
                if (DataColumn.DataField == ColumnText)
                    return Index;
            }
        }
        return -1;
    }
