How to get the cell value by column name not by index in GridView in asp.net

GridView does not act as column names, as that's it's `datasource` property to know those things.

If you still need to know the index given a column name, then you can create a helper method to do this as the `gridview` Header normally contains this information.

    int GetColumnIndexByName(GridViewRow row, string columnName)
    {
        int columnIndex = 0;
        foreach (DataControlFieldCell cell in row.Cells)
        {
            if (cell.ContainingField is BoundField)
                if (((BoundField)cell.ContainingField).DataField.Equals(columnName))
                    break;
            columnIndex++; // keep adding 1 while we don't have the correct name
        }
        return columnIndex;
    }

remember that the code above will use a `BoundField`... then use it like:

    protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            int index = GetColumnIndexByName(e.Row, "myDataField");
            string columnValue = e.Row.Cells[index].Text;
        }
    }

I would strongly suggest that you use the `TemplateField` to have your own controls, then it's easier to grab those controls like:


   
       
           
               
                   
               

           
       
   


and then use

    string columnValue = ((Label)e.Row.FindControl("lblName")).Text;
